I'm writing the test for Macrob this year
I need tips particularly in Comprehension and writing.
Thanks! :) ;)
Post by: Phoenix11 on January 02, 2016, 02:22:03 pm
I really appreciate it.
Thanks again!
I will try to post my writing piece as soon as possible.

Personally, I found it easiest to read the question first and then quickly skim the extracts to identify the useful information and then read those parts more carefully. But I know some people who find that more difficult, so it's ultimately up to you to experiment.
I also remember having read a few of the extracts somewhere/knowing the story for some reason so I only read the first few sentences and just answered the questions based on memory. Not too sure if it's still like this, but they might be recycling stories/extracts? If so, reading broadly would be good - even if it's not the case, it'll help you with your vocab and other stuff!!
And if you can't finish it, just guess! lmao, you don't need to do everything perfectly to be offered a place, I remember I walked out guessing half the questions and it was fine!

Can't help you much with writing (the tests I did the worst in), but try not to overthink it. With the tiny amount of time you're given, they are not going to expect a perfect essay, so don't worry too much about getting the wording perfect etc.
For the multiple choice tests, as sprout said, just guess if you don't have time. For the maths test, I still had 20-30 questions unanswered when the lady said "5 mins to go", so I just randomly circled bubbles and somehow got a superior :P Try not to leave anything blank, you've got nothing to lose!
Best of luck :)

Thanks a lot

I'd recommend looking at the topic, swiftly thinking of 3 arguments (they don't have to be in-depth or groundbreaking, just some sound arguments) and writing three coherent body paragraphs. They do not need to have glossy words, just use simple words (if u have gr8 words then use em but it isnt a requirement... it wasn't for me)
If you write a sound essay, with three good fleshed out body paragraphs (try follow a teel structure or what not) you should be more than fine, because you are competing with others.
Dont worry about being absolutely unique and outstanding (if you can that's great, but dont fall into the pressure that this instills)
gl and happy studying :)

Thank you for all your help guysHi, I am a former Creekside Student and am currently a Melbourne High student. Creekside has a special program for talented kids. It's nothing like SEAL but it gives you more challenging work. Basically the only way you can join the special program is by your teachers referring you to the teacher operating the class (Who I believe should be Ms Verstageen I hope that's how you spell her name). You can't really ask to join the program, after your teacher refers you to the program you have to sit a couple of tests and usually if your in the top 8 or 9 students in year 8 you should be able to join the program. I'm not sure who you have this year, but if you do have Mr Bieg by any chance talk to him about wanting to go to MacRob he has some experience with the Selective School Program as he was a student teacher at MHS. Mr Bieg was my teacher last year 😀! Good Luck!
I will study hard.
Post by: Rick Grimes on January 30, 2016, 05:05:29 pm
HiAll the same. Although I went to the Glen Waverly and classes in the East to hopefully find some kids from high ranked schools (SEAL and Private) and to see how intelligent they were.
Does anyone know if in Hendersons,all the branches are the same or are there more preferred ones?
Thanks!

Yeah I go to the extension class with Ms Vesteegen.
Did the maths Olympiads too. ;)
Post by: Phoenix11 on February 01, 2016, 08:58:35 pm
I was wondering if you knew how many students wrote the exam and how many people got in
And also Mr Bieg left the school
Do you know any other teachers that will be helpful for the Selective school.
Thanks!

Does anyone know what order the tests are going to be given in the real exam..
Or if it changes every year?
Thanks!

Thanks Pi for all the tips on getting into MHS, I just won the junior cockhouse here as Forrest, hopefully we go to win the house cup.
Anyways, for comprehension, the best thing to do is to skip to all the easy definition type questions and answer them as quickly as possible, after that, go to all the ones with shorter texts as you can get through them faster, don't do the poems if you suck at them.
Know your practice exam topics, last year a complete replica of a text in the practice exam came up on the test and I managed to answer about 7 questions in 20 seconds due to that.
Other than that, just keep reading and improve your comprehension skills to a point where you can easily breeze through a text and understand it, start out with newspapers such as the herald sun.
Good luck :)
PS. The swimming carnival is tomorrow, what tram line do I take to MSAC once I reach flinders -_-

Hi guys

Thanks!
It will be given out a week before the exam.
From my memory, it was:
Verbal
Numerical
Persuasive
/break/
Comprehension
Maths
Creative
I think it was like that, been a while since I took the exam, might be different
Oh well

Got some of the best teachers here.
De korte for home room.
Kemp for Japanese
Veale for PE and health
Also someone else, I think it was Mt Moore for geography, he is the second longest serving teacher here and is an Essendon supporter, maybe got the name wrong.

Thanks!
As a former Creekside student, I can answer for Rick. Last year, around 20 students tried out for the test. But only 10 got in because of the 5% percent cut off mark. In 2014, I only know 4 people who got in, but no idea how many tried.
Don't really know any teachers that can help, but you can ask the teachers for harder work.

The test is at 11:30 am.
Anyway i have a question that i can't figure out.
Can you guys please solve it?
If an aeroplane flies at 800 kilometres per hour for one third of its flight time, what is the speed it flies at for the rest of the journey if it has an average speed f 750 kilometres per hour for the total trip?
Thanks a lot.

I have another question that i need answered.
A block 8x5x6 was made to look solid from the outside, bu the outside blocks were stuck together so that the entire block was hollow on the inside. How many cubes would fit in the largest space possible which could be left within the block?
Thank you for the help!
;D
Post by: pi on June 11, 2016, 03:54:57 pm
Try looking at a simple 3x3x3 structure that is hollow. If it wasn't, it would contain 3*3*3 = 27 blocks. But if it was hollow, we would find the hollow volume by subtracting the blocks that make each face from each direction, ie. the hollow section would be (3-2)*(3-2)*(3-2) = 1 block. Always helps to break things down into something super simple for questions like this.
Post by: Phoenix11 on June 12, 2016, 11:39:38 am
I understand how to work out the question now!
I have another question that i need answered.
a+bc=-1
b+ac=-1
c+ab=-1
Which of these values of a is one solution for this system of equations?
A) -2
B) -1
C) 0
D) 2

- Factorising
- Linear Graphs
- Pythagoras
- Measurement (circles in terms of pi)
- And the last 10 questions were all trigonometry in terms on sin/cos/tan

To be honest with you: i don't know if i'm going to get in.Same here... I keep thinking that I've answered every question wrong, now... arghh
However my tutor did help as i learned stuff and tips i didn't know before.My JAC class did help, although not as much as I hoped.
Ah well, we get our results in just under 8 weeks... Oh, how uncomfortable and anxious the next 8 weeks will be ;_;

Post by: Genny.Bot on June 18, 2016, 11:51:19 pm
Oh okay.
How did you guys think you went with writing?
I think I went pretty well with my creative piece cause that's my forte and I somehow to managed to write something that seemed deep/dark. Persuasive was okay, I couldn't find three arguments for either side so i went with yeah they got paid too much and wrote a rebuttal. Overall I think I did okay for the writing portion :-\
You?
Post by: Phoenix11 on June 19, 2016, 11:24:50 am
I reckon i did better in Creative than Analytical but i finished them both in time so that was a relief.
For Analytical, i wrote about how they were getting paid too much and then so i wrote two body paragraphs which were the arguments, rebuttal and then conclusion.
:)
Post by: nights on June 19, 2016, 11:35:04 am
How did you guys think you went with writing?
For persuasive, I wrote two paragraphs 'for' the topic and one rebuttal. Two of my arguments were just based on what I read from the short text provided... I hope they don't deduct marks for unoriginal arguments :-\
Also, I forgot to state my contention clearly in my introduction, and define key words, etc... I was going for a more un-basic style of writing, so I hope both the examiners aren't specifically looking for those persuasive features -_-''
Creative was fine, I just needed to write one or two more sentences to really polish/finish off my essay. I didn't really have a plot, it was more of a descriptive piece... I ended at a point where the protagonist gets bathed by the contents of the box, and the surroundings fade away, etc, so I hope the examiners don't consider it as an unfinished essay ;_; I've heard that unfinished essays get put in one of the lowest categories, without much consideration.
Also, the prompt was really similar to one I got in Hendersons (you approach a book that says 'do not open')! So I didn't really have trouble coming up with ideas.
Generally, I don't think this year's prompts were as difficult as to the ones from previous years. Writing's usually my strongest area, but I'm still a little concerned about my essays since they lacked a few essential writing features/elements... :'(
Post by: Genny.Bot on June 19, 2016, 11:42:19 am
For persuasive I did almost the exact same as you two paragraphs for it and a rebuttal, I did the classic persuasive features though (definitions, clearly state. it was very template-like).
For creative, my person was trapped in the room and they were in a 'facility' and the box was a 'test'. Though I don't think it was bad, I think I could of added a few more sentences to really finish it off nicely.
I heard one of the prompts a few years ago was 'Imagine a world without sunlight' and I thought it would be something like that which would have been more enjoyable to write but I guess not.
Post by: nights on June 19, 2016, 11:50:23 am
I did the classic persuasive features though (definitions, clearly state. it was very template-like).Now that I think about it, I think we had to include those to get a reasonable score :-X
I heard one of the prompts a few years ago was 'Imagine a world without sunlight' and I thought it would be something like that which would have been more enjoyable to write but I guess not.I think last years (?) was 'imagine if you could read minds'. I agree, this year's prompt was not that interesting...
Post by: Genny.Bot on June 19, 2016, 12:00:38 pm
I'm not actually sure how they mark it which is why I was a bit iffy about writing a rebuttal in the first place. Meh it was okay all in all but I think it could have been better.
Post by: nights on June 19, 2016, 12:22:37 pm
they specified that it was a small boxReally? :o I didn't pick up on that, but I'm pretty sure I mentioned that the box was pretty small.
I'm not actually sure how they mark it which is why I was a bit iffy about writing a rebuttal in the first place.At my tuition, they said including a rebuttal was fine.
I think they mark your essay out of X or something, and you get a mark for showing good structure, vocab, etc...? Meeting a certain criteria will gain a point, if that makes sense. That's how they marked our essays at my tuition, anyway.
Eg;
Good paragraphing?: 1
Consistency of tense?: 1
Powerful language used?: -
...
Final mark: 12/20
It's not an unfamiliar method of marking essays, but don't take my word for it, I think this is their method.
They said 3 people were gonna be marking all 3,000 of our essays! I think it's to make our final mark more fair.
Meh it was okay all in all but I think it could have been better.That sums up how I feel rn
Post by: Genny.Bot on June 19, 2016, 12:45:49 pm
Though I feel like the worry for the exam will drift away soon, it will probably linger in the back of mind for the weeks to come...
Heh and the few days before the results come out, that'll be hell.
Post by: Phoenix11 on June 19, 2016, 01:02:27 pm
Do you think they mark one piece together or separately?
Post by: Genny.Bot on June 19, 2016, 01:22:29 pm
Post by: Phoenix11 on June 19, 2016, 01:32:37 pm
However it's going to take a really long time to mark the writing pieces that is both analytical and creative.
Post by: nights on June 19, 2016, 01:34:41 pm
I actually have no idea how they mark the exams.. Like I was almost unaware until after the exam had been completed ;-;
They compare your results against everyone else who sat the exam, which reflects upon the score you will receive later in August.
Your score from each test will be put into one of the six categories: below average (bottom 20%), low average, average, high average, above average and superior (top 12%).
Eg; your score for maths is 30/60, which places you in the superior category for maths, as only the top 12% of the population obtained that score.
Generally, to get a place at any of the schools, you'd need to get at least a high average for a few tests, and about one superior at the least.
However, your current school affects how likely you are to get an offer, if the 5% rule applies.
Eg; you go to a school with 200 students in your year level and 12 people are trying out for the schools. Even if you performed really well on the day (but not as great as everyone else who tried out from your school) you might miss out on a place as only 10 people (5%) from your school can be accepted.
Essentially the marking system is just based on how you performed compared to everyone else.
Hope this helps…
Do you think they mark one piece together or separately?
Probably separately, but they're likely to cross-check with each other

Essentially the marking system is just based on how you performed compared to everyone else.
Hope this helps…
Thanks so much!! This helps me understand it a lot, your way of speech (text talk?) is very easy to understand.

Your score'll be put into one of the six categories: below average (bottom 20%), low average, average, high average, above average and superior (top 12%).By this, I meant your score for each test

Do you guys know the exact date we get our results for whether we get in or not?
:D
The outcomes will be sent out via email or text (?) on the fateful morning of August the 11th.
The actual results of our performance comes out later in August (the 31st?).

I really wanna get in, I've been hyping myself up for it. Though considering how badly I performed in numerical and math.... *cringes*
Post by: nights on June 19, 2016, 10:03:42 pm
I hope that you two get in with dashing success! ;DI hope you get in, too! :)
I really wanna get in, I've been hyping myself up for it.I'd only be concerned about not 'getting in' if I came from a 'competitive' school with over 50 or so kids trying out, i.e GWSC... The 5% rule doesn't apply to me, thankfully
I'm really hyped about it as well, I really don't want to stay at my current school
Though considering how badly I performed in numerical and math.... *cringes*I'm sure those two tests (out of six!) wouldn't affect your chances too badly... yes, they were my weakest, too... ughhh...
But hey, one of my friends didn't even shade in their remaining bubbles (about 30 of the remaining ones)!
I avoided spending too much time on a single maths question, so I skipped heaps in between and only confidently answered the 15 or so questions I knew I could work out in a minutes' time. The rest of my answers were either all C's or 'educated,' yet probably bad guesses.
I thought I was prepared for maths, but nooope, I spoke too soon...
I don't really care about my Numerical and Maths results anymore, cos I think my other scores'll make up for it
Post by: Phoenix11 on June 19, 2016, 10:12:01 pm
For me, Numerical was the worst.
It's going to be so long until we get the results.

This really makes me feel a lot better and I'm the same as you, I really don't wanna stay at my current school. I think that 20-25 people tried out from my school. I'm not sure if that counts as competitive though (like 150 people in my cohort?). And yeah though I'm not very proud of my maths and numerical, I'm fairly confident in my verbal reasoning and reading comprehension.

I think that 20-25 people tried out from my school. I'm not sure if that counts as competitive though (like 150 people in my cohort?).Time for the maths ~
5% of 150 = 7.5, which should be rounded down to 7. 7 people from your school can get in, out of the 20 people trying out. :-\
So it is a little competitive... 20-25 people is a lot, there's only about 5 people from my school trying out
Does the 5% rule makes more sense? I don't think I explained it clearly before

Do y'all remember those questions about what is certain, most likely, etc. to happen based on a short text in Verbal Reasoning? Did you guys find that confusing, hard...? I guessed A (certain) for all of those questions (which was about 15?) since I knew I'd waste away too much time on those :-\
Oh really? I thought those questions were quite easy, though I didn't answer a few of them until the end. I finished most of questions with about 5-10 minutes to spare and then did those ones when I had time left.

The 5% rule is talking about how much it is of a cohort in your school. For example, if your school had 100 students, 5% of it is students. This means that only 5 students can only get into any of teh selective schools which are Melbourne High, Macrob, Nossal and Susan Corie.
They will send you an email if you got in and if you didn't, ii'm pretty sure they won't send you anything. Then a week later or something like that, they send your actual results which are how many superiors and above averages you got etc.
Post by: nights on June 21, 2016, 06:58:21 pm
Can anyone go in depth into the 5% rule and how the offers get sent, like will they email you saying you didn't get in or something like that?If you need more details:

I haven't really put in much thought about a negative outcome, since I can't imagine staying at my current school until year 12.
You already go to a pretty fancy school (presuming from the fact that you go to a single-sex school), so you shouldn't be THAT disappointed if you don't get in... of course, it's exciting to go to a prestigious school and all, but just be thankful that you'll continue at a nice school if you don't make it through...

Um actually, I've gotten a scholarship to some school so i'll be going there if i don't get into Macrobertson.You've been offered a scholarship to another school, yet you're unconfident that you'll get an offer to Mac Rob...
What are you going to do for another choice?I'm probably doing the SEAL test later this year, for year 9 entry into one of those higher-end public schools.
:)
I actually sat a scholarship exam at the start of the year, too, but I didn't get an offer (too many people sat the exam, and about 10 spots for year 9 entry).

Well Macrobertson is a bit different to the school from which i received the scholarship as... you know...more people trying...like more than 3000.Actually, around more than half of that is sitting for MHS, SCHS or Nossal. It's around a 20%~ or so chance for entry.
:D

It's better than "chance" for you guys, because you guys actually studied :)
Best of luck all! I fondly remember getting my results over the phone from my parents (back in the day it came via mail, how times have changed!) when I was in Melbourne Central coming back from school on my birthday. Was a pretty decent present.
You'll all be fine :) And even if you don't happen to get in, you can still succeed in other schools if you maintain your positive outlook and study hard :)

Hi Everyone!Hii
How is everyone, it's been more than a month since the exam, and less then two weeks until we get our results back!! Is everyone coping well? :-[ :-X
It's actually 12 days from now, that's less than two weeks ;_; :-X :(
I've been training myself to keep my hopes as low as possible, so I don't feel too hopeless if I don't make it through (which I've learnt to be a highly unlikely outcome, anyway)
Ever since the exam, I've just been really bored lately (bored in school, being super unproductive unless there's homework to do at the last minute), and also since my report was pretty frustrating (some of my friends got A's only because they had pretty lenient teachers; our teachers are very inconsistent when it comes to reporting) I've been even more disinterested in anything school-related :P mehhh, I'm sure I'll get my motivation again...
What about you guys? :D
Post by: Phoenix11 on July 30, 2016, 03:02:34 pm
Yeah i'm coping pretty well.
It's just that i guess i am focusing more on school work as i don't have the test to think about or how i could get better.
I'm not being very productive either after the test so i am trying to get back into the flow and learning about other things.

:D I got in! The email was actually sent in the junk folder, and I didn't realise that until ten minutes ago. I'm so surprised because halfway through the Creative Writing I realised that I had misread the prompt (I thought that the character was stuck in the box that said "DO NOT OPEN"), and so I had to restart the entire thing. Also during the Mathematics, I guessed about half of it, not knowing what to even do.
Also, congrats to everyone else who got in!
For mathematics I was the exact same. I got barely halfway when I realised there was barely 5 minutes left so I circled all Cs and with the spare time left I look at some questions and changed the answers to what was probable :P
Congratulations!!

I got the second round offer a few weeks after the first round offers. If you get into your second preference school (e.g. Nossal or Suzanne Cory) and get a principal's discresion, you will have a good chance of getting into Melbourne high via second round offers.

If you get into your second preference school (e.g. Nossal or Suzanne Cory) and get a principal's discresion, you will have a good chance of getting into Melbourne high via second round offers.You mean if I got a PD to my second preferred school during the first round of offers?
My second preference was MHS, and my first was NHS… I didn't get a PD to either of the schools.
Did you get a PD to your second preferred school?
Also, did you get any superiors? If so, how many?

Second round offers should be out by late August to early September. I got an offer to Nossal which was my second preference school and a principal's discresion for mhs, my first preference school. Did you get an offer for suzanne cory? If you did, then you have a decent chance at getting into Nossal for second round offers. I only got 1 superior, but I still got into mhs, since I went to a pretty bad school, so it was easier to get in.

So, both the offers you got were late offers?
And do you think second round offers are pretty likely? i.e how many people do you know got a late offer?
Sorry, I have too many questions about these offers >.<

Sorry, I have too many questions about these offers >.<
The offer to Nossal was a first round offer for me, but the offer to mhs was a second round offer. I know quite a few people who got second round offers, so it happens quite often. This is because some people just take the exam to test their abilities. Also, for private school kids sometimes they can't leave their current school because if they do they have to pay back their scholarship. Seeing as you didn't get an offer to any of the schools, it may be unlikely that you get into either mhs or nossal, but you may get a late offer to suzanne cory.
But, if you participate in cocurricular activities, you should consider taking a test and interview for year 10 entry next year. Also, John Monash is another great selective school you should try out for (pretty sure it's about as good as nossal in rankings). There are still more opportunities for you even if you don't get in this year.

Seeing as you didn't get an offer to any of the schools, it may be unlikely that you get into either mhs or nossal, but you may get a late offer to suzanne cory.Heyy, your prediction turned out to be correct ;)
I got a late offer to Suzanne Cory on the 22nd, just over a week since the initial round of offers. I didn't really expect to get any late offers (especially getting one this early), but I suppose people rarely put down SCHS in their preferences.
We accepted the offer, but we hope it'll get replaced by Nossal or MHS later this year.
UPDATE: got an offer to Nossal around early October.

You got into Nossal! I'm so happy for you!
Good luck at MacRob next year!
Well for preparation classes, I went to JAC!Went to JAC for about 10 weeks, and did 1 Hendersons mock exam a week prior to the exam.
Where did you guys go?
Did JAC actually help you? Their course was pretty poor imo.
How were your exam scores? :D

Also they gave a mock exam a week before the exam.
Their writing feedback was good too.

Does anyone know how to solve this problem?
A man cycles at a certain speed, then motors 30 km at three times that speed. Altogether he is travelling 1 hour and 20 minutes. Find his cycling speed.
Any help will be greatly appreciated!
Thanks again!

Post by: nights on October 16, 2016, 04:05:19 pm
JAC was helpful as we did practice tests every week or second week.They did help in terms of practice, but I just found their test questions pretty different to those in the actual exam :P
Also they gave a mock exam a week before the exam.
Their writing feedback was good too.Agreed :)
A man cycles at a certain speed, then motors 30 km at three times that speed. Altogether he is travelling 1 hour and 20 minutes. Find his cycling speed.Can't help you here, sorry :o dealing with rates/speeds is my weakest area in math
All I know is that speed = distance/time, but I don't think it's that relevant to this question :P

How are you?
Long time, no see!
I was just wondering if anyone knew how to solve these questions?
a) Use the discriminant to show that the line y=2x+1 does not intersect the parabola y=x^2+3.
b) Determine for which values of k the line y=2x+k does intersect the parabola y=x^2+3.
Thank you so much, you guys!

I'm not very good at explaining so can someone else please explain the steps in more detail? Thanks.
Spoiler
For an intersection, we need to have both equations equal to each other.
Using the quadratic equation, we know that =ax^2+bx+c)
Therefore,
Now we can use the discriminant formula:
^2-4(1)(2))
Since D<0, we know that the lines do not intersect.
Therefore,
Now we can use the discriminant formula:
Since D<0, we know that the lines do not intersect.
Spoiler
Again we equal both equations to each other and rearrange:
Using the discriminant formula:
(3-k))
For there to be one solution
For there to be 2 solutions 
Therefore, for any solutions
For there to be any intersections, k≥0.
Using the discriminant formula:
For there to be one solution

Hello everyone!hey ! So it's been a while since i did this desciminant stuff but I'm pretty sure for part a) you equate the two equations and then combine both equations so that the right hand side of the equations equals to 0. Them you use the values for 'a', 'b' and 'c' and substitute them into the discriminant which is b^2-4ac and if the answer is > 0 there should be 2 points of intersection, if the answer = 0 than there is only one point, it should be tangent. If the answer is < 0 (which is the answer you should get in this question) there are no points of intersection. Correct me if I'm wrong guys, I'm a bit rusty on this haha
How are you?

The left side gives you a parabolic equation. Since you know the intercepts, do a quick sketch of the curve y=(m+2)2 - 16 and find the values of m for which the graph is greater than zero i.e. above the m-axis.

But how would the answers be m>2 and m<-6?

Hello.Have a sketch of the graph ∆ = (m+2)2 - 16 and label the intercepts
Thank you for responding.
But how would the answers be m>2 and m<-6?
(Note ∆ is basically the same as y, and m is the same as x - we're just using different letters/variables to fit the question)
You can see that when m > 2 OR m < -6, the value of ∆ (discriminant) is positive i.e. this is when the discriminant is greater is zero.
Hope that clarifies things :)

For the same question above,
b) intersects the line in two places.
c) does not intersect the circle.
So for 'is a tangent to the circle (i.e. one solution), i got ±√3.
For question b) and c), how do we figure out which sign(> or <) to put for each number(+√3 or −√3), without drawing a graph?
Post by: Shadowxo on August 23, 2017, 04:02:01 pm
OK, so if we continue on.You either have to draw a basic graph / know the shape of the graph or use common sense (or just testing a point) to figure out if it's < or >
For the same question above,
b) intersects the line in two places.
c) does not intersect the circle.
So for 'is a tangent to the circle (i.e. one solution), i got ±√3.
For question b) and c), how do we figure out which sign(> or <) to put for each number(+√3 or −√3), without drawing a graph?
Eg (x-4)2>16
You know as x gets larger than 8, (x-4)^2 gets larger than 16, and when x is below 0, it's also larger than 16 so x>8 or x<0
Basically, no easy way to do it, drawing a basic graph is usually the easiest :)

I was wondering if anyone knew how to solve this question?

Find the probability that the card is an ace and not a spade.

Recall the addition rule for probability:
What are the probabilities on the right hand side? Can we work them out?
Hint
What's the probability of not getting a spade? What's the probability of getting an ace? What about either a non-spade or an ace?

I just have a quick question.
So Pr(A'U B')
=Pr(A')+Pr(B')-(AUB)
Using this method I got an answer for a different question.
Now why do you have to subtract AUB when there was no interserction to be subtracted from?
As in Pr(A')+Pr(B') there was no intersection of AUB involved right?
Thank you so much!

Thank you so much!
Pr(A' U B') = Pr(A') + Pr(B') - (A' U B')?
The reason that you subtract the union A U B (not intersection, A n B) is because when you're looking for the probability of picking a card that is an ace, but not a spade, you will be adding the total number of aces and non-spades, and subtracting all that aren't both an ace and non-space.
This might be confusing, so I'll try explain using another example. Let's say we have the numbers {1, 2, 5, 10, 15}. Pr(odd number) = 2/4 = 1/2, and Pr(divisible by 5) = 3/5. What about Pr(not even AND divisible by 5)? The only numbers that fulfill this are 5 and 15. That is, we find all the odds (1,5,15) and all the numbers divisible by 5 (5, 10, 15). Now, which are both odd and divisible by 5? 5 and 15. We had to eliminate those which weren't both (1, 10).
That is, Pr(odd and divisible by 5) = Pr(odd) + Pr(divisible by 5) - Pr(odd OR divisible by 5)
I hope the example didn't confuse you even more, but hopefully this clarifies things :)

Pr(A U B) = 13 + 9 - 3

So everything outside the union is 5, or likes neither which is 5/24

However I still don't know how to do it with a tree diagram as I tried but I am a bit confused.It says "The probability of rain on any particular day is 0.2" so start off with this. Create one branch with "rain" (I recommend using R) and probability 0.2. The other branch will therefore have "not rain" (NR) with probability 0.8.
From there, you should know the rest of the probabilities. For the Rain branch, you know the probability of rain on the next day is 0.85, and not rain is hence 0.15 ("The probability of rain on a day after a rainy day is 0.85"). For the Not Rain branch, use the same logic using the numbers for when the day before didn't rain (using "The probability of rain on a day after a non-rainy day is 0.1")

Consider, the probability of flipping a coin and landing a heads (1/2) and the probability of rolling a 4 (1/6) on a standard 6-sided die. If you write out the entire sample space and circle all that satisfy heads on the coin and 4 on the die, you will see that you have circled 1/12 (= 1/2 x 1/6) of all the possibilities.

Hello guys!It's been a while, but to conduct electricity you need charged particles (ie positive or negatively charged particles) that can move around (so liquid or aqueous, or electrons free to move). Some substances dissolve in water to form + and - charged particles, this means they conduct electricity.

Eg lead is a metal so has electrons that can move around. It'll conduct electricity.
Eg potassium nitrate dissolves into K+ and NO3-, and can move around in water (soluble / aqueous) so does conduct electricity.
Edit: I was only thinking about materials that would result in water conducting electricity. Some answers will depend on the experiment (eg was it a big block of salt or was it dissolved in water? It'll conduct if dissolved in water but won't if it's just in a big block, as it won't be free to move)
Fixed accordingly
Post by: Yan035 on September 12, 2017, 05:39:59 am
Potassium nitrate and salts have ionic bond. This means when they dissolve into water they will form ions which are also conductive.
Sugar and wax are kind of organic and they have covalent bonds. they don't form ions in water, so they are not conductive.
Deionised water, from its name you can tell there are no ions, so not conductive.

I just wanted to ask a quick question. Why can't the bases of logarithms be negative?

:)
So we can't draw a proper graph for a negative base, and can't manipulate it well. If it's positive, it's continuous and we can use the rules relating to bases.
In theory we could say log-2-8=3 but we couldn't do much with it. Like, what does log-22 equal? Whereas for positive bases, we can use it to find a variety of non-integer values on a continuous scale
Sorry if it doesn't make much sense but hope this helps anyway :)

Sorry about the misrepresentation.By doing long division you would get x-1+(4x+1)/(x^2-1)
I meant (x^3-x^2+3x+2)÷(x^2-1).
But if you wanted to solve when the equation was equal to zero, its still not possible without a graphics calculator because the numerator is a cubic that can't be grouped.

There are a couple ways to do it, and it'll depend on what you've been taught. One way is long division, like Eric did. Another way is to just group terms / introduce terms.
If you haven't learnt this, don't worry about it. It's just another way to do it. How they expect you to do it will depend on what you've been taught :)

Find the equation of the circle with centre (2,-3) which touches the x axis.
Fidn the equation of the circle which touch the x axis, have radius 5 and pass through the point(0,8)
Thanks guys ;)

Guys how do you solve the following questions.For the first question, you know the coordinates of the centre you just need to determine the radius. Since the centre is three unit below the x axis, for it to only touch the x axis, the radius would be 3.
Find the equation of the circle with centre (2,-3) which touches the x axis.
Fidn the equation of the circle which touch the x axis, have radius 5 and pass through the point(0,8)
Thanks guys ;)
So your equation would be (x-2)2+(y+3)2=32
The second question is a bit harder though.
Since you know it has a radius of 5 and touches the x axis, you know the centre is either 5 units above the x axis or 5 units below the x axis. But since it passes through the point (0,8) you can deduce that it is above the x axis.
So you know the centre of the circle has a y coordinate of 5 and a radius of 5 and passes through the point (0,8). Because it is a circle, the distance from the centre to any point on the circle will be the radius. So you know the distance from the centre to the point (0,8) will be 5.
Let a be the x coordinate of the centre, giving you the two points (a,5) and (0,8). Using the distance formula this gives you:
This gives two circles which have centres of (-4,5) and (4,5), giving you two equations;
(x-4)2+(y-5)2=52 or
(x+4)2+(y-5)2=52
Hope this helps :)

Find the equation of a circle which passes through the points A(0,2), B(2,0) and C(-4,0)

Great answer by Eric :)
Another way to do it, is by using the formula for the circle again. As you know the centre is (a,5) and the radius is 5, you can write the equation of the circle as
(x-a)2+(y-5)2=25
Subbing in (0,8) you get
a2+9=25
a2=16
Which results in the same answer as Eric got
Thaaaaank you soooo much! Can you also help me with this one?You have two useful points (2,0) and (-4,0). From this you can deduce that the centre has an x value between these two points (as they have the same y value). So h=(2-4)/2 = -1
Find the equation of a circle which passes through the points A(0,2), B(2,0) and C(-4,0)
From this the equation of the circle is
(x+1)2+(y-k)2=r2
Sub it a couple of these points to get the values of k and r

I was wondering if anyone knew how to solve this question?
Find the values of p for which the equation px2+2(p+2)x+p+7=0 has no real solution.
Thank you so much guys!

Hello guys!

Thank you so much guys!
A quadratic has no real solutions when its discriminant is less than 0 (i.e negative). Discriminant = b2 - 4ac, wherein a = p, b = 2(p + 2), and c = p + 7. Plug all those values in, make it < 0, then solve for p.

Thank you so much! I figured it out.
I was wondering if anyone knew how to solve this question?
Show the equation x2+4mx+24m-44=0 has a solution for all values of m.
Also, since if a is negative and c is positive and the graph gives two solutions(in ax2+bx+c), does that mean that there are two solutions for all values of a,b,c?
Since in these questions:
a)Find the discriminant of 4mx2+4(m-1)x+m-2=0. I got the answer 16
b)Show the equation 4mx2+4(m-1)x+m-2=0 has a solution for all values of m. Since the discriminant(16) is higher than 0, there are two solutions. Now does that mean for all values of m, there are two solutions?
Thank you so much.
This is greatly appreciated.

for your first question, the equation has a solution when the discriminant is greater than or equal to zero. Plug in the values and you should get something with the form am2 - bm + c ≥ 0. <-- This is essentially telling us that the parabola is shaped like a smiley face. In order to show that it's positive for all values of m, you have to show that the turning point is positive (b/c if it is, the entire graph is above the x axis and therefore positive - and also all values of m). You can do this with the formula x = - b/a and using the x point you get to find the corresponding y value.
for your second question, yeah ( i think? check with someone else - i'm not entirely sure, sorry :-\)

Yep, lovelyperson is right. The discriminant is 16 for all real values of m, and so this also means that there are 2 solutions for all values of m :)

I really appreciate all your help!
Okay, so I am just posting a piece of my argumentative writing here and I was wondering if someone could give me feedback for it? I am not too sure about the arguments so it would be great if someone could confirm that my arguments are valid and make sense!
Also, when should we use will, might, may, would and should in this situation as I don't know whether we should stick to one modal verb in the whole essay or whether we can use it at different times, depending on where it makes sense. The modal verbs I am not sure about are in bold
Also, for my third paragraph, are there too many ideas and if there are should I limit it to one whole idea and expand so the main theme is more clear?
Sorry for all the questions!
Any feedback at all is greatly appreciated!
Thank you!
The minimum driving age should not be raised.
The minimum driving age exists to ensure that young, curious drivers have an experience that is worth remembering. However, raising the minimum driving age will limit the drivers' freedom. The minimum driving age should not be raised. If the driving age is raised, there would most likely be rebellious minors who may still drive without a licence anyway, causing havoc. Also, teenagers need to be able to learn from their mistakes so the driving rule should stay unaltered.
To begin with, the minimum driving age should not be raised as a teenage rebellion may arise, ultimately causing havoc. Teenagers specifically want to adhere to their own desires so if the minimum driving age is raised , they would not comply to the rules. They may create havoc in the society by persuading people to join their campaign for young drivers' rights. For example, there may be long arguments between these youngsters and their parents and other adults. This will ultimately cause unnecessary conflicts that the government will eventually have to solve so we should keep the teenagers comfortable with the current driving rule. Therefore, the minimum driving age should not be raised as unnecessary conflicts may arise within communities.
Furthermore, keeping the minimum driving age unchanged will mean that teenagers can keep making mistakes, which they can learn and benefit from. Raising the driving age will only delay the process of teenagers learning from their own mistakes when driving a car so it would advantageous if they learnt it at a younger stage when they are still accepting new things. This would eventually limit the mistakes these minors might make in the coming years. For instance, drink-driving an text-driving are global issues that affect people and individuals around them. If someone was drink-driving and nearly struck a person walking across the zebra crossing, they will learn that you shouldn't drink and drive. Since they experienced nearly killing someone, they would associate drink-driving with a bad consequence, allowing them to be more aware of their actions. Since young drivers such as 17 year olds are immature, they will have more situations to learn from their mistakes. Hence, the minimum driving age should not be raised as teenagers would be able to learn from their mistakes earlier, limiting mistakes later.
In conclusion, the minimum driving age should not be raised as teenagers might cause a rebellion, meaning conflicts may arise within the society. Also, teenagers would be able to learn from their mistakes by experiencing many situations at a younger stage.
