I ONLY FOUND ONE SIDE OF THE LID AHHHHHHH others found both, rip that 50
-
Apart from the ambiguous lid question I found it easy, easier than past exam 2's imho. But I have done all vcaa exams
-
Hope you all nailed it! :D
Can someone post the exam? ❤️❤️❤️
We will be at some point - might be a slight delay. :)

anyone know if we needed to find both sides of the lid or just one?

Anyone know what the answer for the second last question for matrices was?
-
Found the 1x3 L matrix question difficult. The wording wasn’t very clear and everything I tried didn’t seem to give me the answer I needed. What was it asking for?
-
Found the 1x3 L matrix question difficult. The wording wasn’t very clear and everything I tried didn’t seem to give me the answer I needed. What was it asking for?
It was asking for a summing matrix for only Rolls and Sandwiches.
Hence L=[0 1 1]
-

The matrix should've [0 1 1], it's asking for the matrix to find the total price of the rolls and whatever the last one was.

How did everyone do on the last couple of questions on the networks module? There were a couple of weird questions in there in my opinion, particularly the quesition about what the "0" in the Hungarian Algorithim meant? And what did everyone get for the max time and min cost reduction on the crashing question?
-

I believe the answer was [0 1 1] since it was asking for the total cost of 2 of the foods. Therefore, one of the element in the 1x3 matrix had to be 0.

That's exactly what I was going to ask! For the Hung Algo I said that Colin must be allocated to Tour 2, and for the new minimum time I did 17 days and minimum cost I did $4000 for the crashing question. That was hard!
-
Can someone please confirm for me the answer for the last Business question= $805.65?

I got the same for the Hungarian! Somehow I only got a reduction by 1 from the original minimum completion time, and $2000 for the crashing q, waiting for a copy of the exam to check!

I'm not sure about the crashing lmao but I reduced L first, giving reduction of one day, then I reduced I, J, and G, which were on the only three different critical paths, reducing another day. :-\

2 Mark matrices question: 25%
2 Mark recursion question: $805.65 or something like that
2 mark graphs question: $220
Last graphs question: 9 & 3
Graphs and relation intersection of 2 graphs: 10.98 minutes
Any other questions feel free to ask.

Whats this I hear about the matrix L question. What could it be besides [ 0 1 1 ]?

For the 2 mark matrices question, I think I got 30% of the senior students who were expected to do Investigation in term 3 and was expected in Service in term 2? It was similar to a question on 2016 VCAA exam 2.

The 0 indicates that the person from that column has to do task 2 because there were no other 0 in that column, or that's what I put?

You sure it wasn't 11.11 minutes?
Edit: omg i put y=-62.5x+1125 and y=50x into my CAS instead of 40... yeah it's 10.98. :'(
-
I got 11 minutes for the graphs and relations question after putting it in my CAS :(
-

I got [0 1 1] too
-

I got 11 too so..
-
what did u guys do for that total question for matrices?
Vague question but I did 750 junior students, or L = [0 1 1], or some other answer to the question you're asking?
-
I got 11 too so..
I got 10.98
It asked for the minutes to two decimal places, so it can't be 11 minutes.

For the last question in Business, i think, was the equation
Ao=428, An+1=1.00125an
-

Yesssss
-
For the last question in Business, i think, was the equation
Ao=428, An+1=1.00125an
I only did An+1=1.015An because the question said the rate was 1.5% per month! :-\

-
I think that matrix question in which L was required was wrong, they stated that the product of the matrix L and the given matrix will give the total cost of rolls and sandwiches over the 3 weeks, but instead it gives the total cost of all 3 food items over weeks 2 and 3?
Am I right?
-
Can someone please confirm for me the answer for the last Business question= $805.65?
Yeah mate thats the way
For the last question in Business it was pretty straight forward
Current value 360000
Find value after 4 years
Put that into ur current
Put your future as 500000
No interest has changed therefore the 800$ or so dollars is your monthly
-
I only did An+1=1.015An because the question said the rate was 1.5% per month! :-\
I did the same.
-
Did anyone struggle to finish?
A lot of people at my school, including me, said that they were unable to.
-
1.0125An I believe
Its already compounded monthly so i think is is 1.015An not 1.00125An

hi guys how many marks will I lose max for stuffing up the significant figures question??

hi guys how many marks will I lose max for stuffing up the significant figures question??
thanks
3 marks if you stuffed up all the significant figure rounding. 2 for the regression equation and one for the question above.
-
It is 1.015An as there is no need to divide by 1200, due to 1.5 being the monthly interest rate. The follow up question regarding the interest charged was $26.26.
The matrices question was difficult to see through but it wasn't 30%, it was 25%. You had to calculate the amount of students that joined I from S and divide by the total amount of students in I in term 3.
-

if I only stuffed one up number??
could I still get consequential marks?
-

They'd definitely make allowances for this when creating the marking scheme, best case scenarion one lost for the rounding, and consequentlials for the regression and question after or, worst case, two marks lost for rounding + regresssion and a consequential if you show that you used the incorrectly rounded figure

4C) Is 709 Hectares
-
hey what was the annual flat rate depreciation percentage looking for? i got 4.5% but how can there be one rate when its decreasing by a greater percentage every year?
The Flat rate of depreciation is a percentage of the initial value, so 4.5% I believe is correct.
-
I only did An+1=1.015An because the question said the rate was 1.5% per month! :-\
That's what i did as well
-
4C) Is 709 Hectares
Thats what I thought, but others told me it wasn't!
-
Thats what I thought, but others told me it wasn't!
Im not quite sure how it could be 708, if you solve it in the cas for log10(y)=-14.4+0.00854*2020 it comes out to 709.251 which is 709 to the nearest hectare?
-
4C) Is 709 Hectares
10^2.85 is 707.9457843841

anyone know if we needed to find both sides of the lid or just one?
I just found one; it was the first question in geometry so I wasn't expecting to have to read into it that much. Plus if you found both sides you're kinda treating it as a 3D object so with that logic wouldn't you need to find the areas of the sides as well? They didn't give us the thickness of the lid so we wouldn't have been able to do that anyway! I feel like if they wanted both they probably would have specified that we had to find the inside and outside but then again that's just me SERIOUSLY hoping that the answer I gave was right, they did use the phrase "surface area of the lid" too so they may have been implying both sides.....it could be either tbh, VCAA does what they want hahahaha

the question specified both the lid and base, it said that in brackets
-
10^2.85 is 707.9457843841
I think what is creating the confusion is the following:
If you use the exact values provided on the exam paper e.g. 2.85, then 10^2.85 = 707.95 ~ 708.
But if you do it off the regression equation: -14.4 + 0.00854 * 2020 = 2.8508 and then 10^2.8508 = 709.25 ~ 709.
Since the answer is provided in the question, I think 708 is the better answer. Or am I wrong?
-
Thats what I thought, but others told me it wasn't!
Nah it was 708 because you solve log10(x)=2.85 and you get x=707.945... which round to 708 hectares to the nearest hectare.
-
Yeah I got that.
-
Anyone know when the answers are going to come out?
-
For that matrices question, 25% or 20%?? I initially wrote 25% and then redid it and got 20% :/

Good point, I can't remember the question well, then I guess both are technically right if you're using any of the values you are given?
-
the question specified both the lid and base, it said that in brackets
Yeah but I think you're thinking of part b because it said it there but in part a it asked you to find the surface area of the lid but didn't specify whether it wanted just the outside area of it or the outside AND the inside area. I though because they specified it in part b and didn't in part a that I would just find the outside area of the lid and not the inside. Seriously have no idea now though.....

Yeh I agree considering they give you the number that you should use that number. It's not methods where you have to use exact numbers...
-

Not exactly sure, but since the value of 2.85 is in the question, I think the examiners would want you to use it and so 708 might be the better answer in this case.

Anybody know if a copy of Exam 2 is available yet?! 😂

Nah nah you're totally right, that makes sense. I did 708 because I didn't even consider using a different value! Also because they give you the value of 2.85 IN the question you would have to use that value, otherwise they wouldn't have bothered giving it to you at all! :)

Can someone please confirm for me the answer for the last Business question= $805.65?

6c is wrong, 7b is 805.65, 4c might be wrong
With 11B, can anyone explain what the answer is. When you use the matrix and solve it, the cost is equal to 3.8. However, the total cost was 487 or something from memory, and 3.8 x 159 (total sandwiches sold) = $604.20. The answer could be found using $487/159 = roughly $3.07. Thoughts?

Hey so is it true that losing one mark in the further maths exam is essentially the same as losing a study score?
-
The matrices question was difficult to see through but it wasn't 30%, it was 25%. You had to calculate the amount of students that joined I from S and divide by the total amount of students in I in term 3.
I see my mistake :( I divided 60 by 200 instead of 240. I should've checked it. I'm so devastated haha
Since it was a two mark question (and I showed my working out, e.g. no. of I students in Term 3=240, no. of S students in Term 2=200, no. of I students that joined from F=60, then percentage=60/200(shouldve been 240, not 200), will I still be able to get a method mark?
-
Hey so is it true that losing one mark in the further maths exam is essentially the same as losing a study score?
I believe so, because further is relatively easy, it is very dramatic and one mark is about one study score around the 45-50 range

What did we think for the final geometry question with the path length, I got 153 by finding the length of the triangle and minusing from radius 50 to get 12 which when adding the 50 times 2 and (65-12) gave me 153m

I think VCAA will only accept 708, but the regression equation is in part i of the same question and I guess it could be assumed that the predictions are supposed to stem from the regression line exactly? idk

For the lid questiobon, did people do one side of both, talking about part a not c
-
I did one because as they didn't give us the thickness of the lid so that wouldn't be the true total surface area anyway

For Question 4 apparently its wrong so im not so sure, and 3)d) for graphs apparently has to be 9.6 and 2.4 instead of the rounded values of 10 and 2, I rounded them because it made sense as you typically dont see 9.6 lifeguards like??

Hey Guys,
For the second question of finance if you divided the 1.5% by 1200, not realising that it was already in the monthly rate, you would drop the mark for part a, but get one mark out of the two for the recurrence relations, for getting the A0 value correct I assume? Would you also qualify for a consequential mark for the last mark of the question if you used your previous (incorrect answer) correctly?
Thanks

In Question 3 of the graphs and relations module, 10 and 2 are outside the feasible region. (As one constraint was y>=x/4 and 2 < 10/4) So the next choice was 9 and 3 as the lowest.

Does anyone have the actual exam (so we can see the ques)???
-
would a SSC of 43 be pushing it?
I heard from my teacher that the standard deviation for further maths is 6. So if the average is 30 and you want a 42, you have to be in the top 2.5% but with the amount of marks you lost, I don’t think that’s possible, so it’s probably pushing it.

Good point, I can't remember the question well, then I guess both are technically right if you're using any of the values you are given?
I've got a copy of the paper. It says 'Using this value of 2.85, calculate the expected area...' so the only accepted answer I believe will be 708.

I'm with you, I got 9048km as well. Plus in exactly the same boat! Average of 97, 1 mark lost on exam 1 and predicting around 0-3 on exam 2. I'm hoping for a 45+ raw score which I hope is possible providing I didn't lose any more than 3 marks on exam 2 which I doubt. With such a high SAC average (not perfect but only worth like 34% of the total) I think it's possible.As soon as you start losing more than 1 mark on exam 2 though it will probably drop your study score by around 1 per mark lost, or thereabouts.

ahh I hope so, If 9048 is right then I only lost between 1-2 (not sure about the surface area of the box including the lid or not, I've seen mixed answers), so hoping that'll be enough for a 45+

Yeah it was all a part of the one question, I used the recurrence relation we set up in the previous part (or you could do 428x(1.015)^4) to get the value she has to pay after 4 months which is $454.2635... and then I subtracted the initial amount to find the interest so 454.2635...-428= $26.26 (to the nearest cent or whatever it wanted) :)

I think that matrix question in which L was required was wrong, they stated that the product of the matrix L and the given matrix will give the total cost of rolls and sandwiches over the 3 weeks, but instead it gives the total cost of all 3 food items over weeks 2 and 3?
Am I right?
Yes, I think so too. I wonder if the VCAA would pick their mistake and credit the students accordingly.
-
Yes, I think so too. I wonder if the VCAA would pick their mistake and credit the students accordingly.
No I thought it was wrong too, but the 915ish number (can't remember) was the total of just rolls and sandwiches over the three weeks. The matrix they were looking for was [0 1 1] I believe.

Please check the question Q1cii Matrices again. I still feel it is wrong. Because the total of just rolls and sandwiches over the three weeks adds upto 965.40 (604.20 for the sandwiches and 361.20 for the rolls)
Yup it is wrong. In cii, if you think about what each row represents, they're totals for weeks 1, 2 and 3. Rows 2 and 3 represent the total earnings for weeks 2 and 3 for all Rolls, Sandwiches AND Pies

Error in the exam. Matrices Q1cii
See the attachment. Clearly, rows 1,2 and 3 represent the total earnings for weeks 1, 2 and 3, respectively. Hence the sum of rows 2 and 3 in Q1cii represent the total earnings for weeks 2 and 3, NOT the total earnings for Rolls and Sandwiches for all 3 weeks.

What score do you think would be possible with;
SAC Score: 82 - 83 / 100
Exam 1: 36 / 40
Exam 2: (predicted) 55 - 56 / 60?
ranked roughly 7th or 8th in my cohort
Thanks!! :)

What did people get for the second geometry question (finding the full surface area)?
-
Found the 1x3 L matrix question difficult. The wording wasn’t very clear and everything I tried didn’t seem to give me the answer I needed. What was it asking for?
I believe it was a 1x3 summing matrix
-
Anyone got the solutions for modules 3 and 4? They have been posted but some seem questionable.
where are the answers?
-
What did people get for the second geometry question (finding the full surface area)?
2x32x19 + 2x32x40 + 2x40x19 = 5296m squared but I've seen other answers so not sure If I read the question wrong?
-
2x32x19 + 2x32x40 + 2x40x19 = 5296m squared but I've seen other answers so not sure If I read the question wrong?
I got the same, and I just checked with a friend so we should be right (hopefully)
-
What did people get for the second geometry question (finding the full surface area)?
I got 5296 as well but like others I am questioning if maybe I read the question wrong.....I’m pretty sure I read it right but won’t know until I see the exam again.
-
When it asks you to sketch the line. Do you need to label the line or label any of the points? WOuld you lose marks for not labelling. (Question 3b in core, sketching the regression line)
-
For the last question on Linear graphs is the objective function 15y+25x or 15x+25y
If it's the second one I got the question wrong but PLEASE SOMEONE upload the
linear graphs part of the exam
-
Study score estimate if dropped 1 mark all year, 40/40 on exam one and 56/60 on exam 2?
Probably sitting around 46-47 I'd think.
What score do you think would be possible with;
...
I'd suggest low 40s, maybe a 41 or a 42.
-

nope you don't have to, confirmed by our further teacher

SAC rank - top 3 in a strong cohort
Exam 1: 40/40
Exam 2: 59/60
Is a 50 still achievable?

Maybe that 1 mark is close to toppling you tbh

I'm totally freaking out! So I think I lost a max of 20 marks combined with both exams and finished with a rank of 7th, what will my study score look like?

Hey, what study score should I be looking at?
38/40 Exam 1
56/60 Exam 2
SAC Ranking: Top 35% of a strong cohort of 100 students
Also, can someone explain to me why the float time is 6 days and not 7 in the networks module? Thanks ;)
-
What about rank 1, 40/40 and 59/60? 50 still in question, or will it be too competitive at the top?

If we did 6b wrong, will we get consequential marks for part c??
Answers so far:
Core Q1ai 72
aii 25%
bi 84%
ii 209
c 105
2a place of capture
b 20mm
c min 16mm Q3 36mm
d 52 is greater than upper fence 50 so it is an outlier
e The median wingspan of moths in grassland is 30mm when compared with median wingspan of moths in the
forest of 21mm. Wingspan is therefore associated with the location where they are caught.
3a egg density = -46.8 + 18.9 x number of male moths
bi choose two points to input into equation given ie (10,504) and (60,2064) and draw line.
ii for every additional female moth caught the egg density increases on average by 18.9.
iii -412.5
iv 74.3% of variation in egg density can be explained by the variation in number of female moths caught.
4a 0.009
b log(area) = -14.4 + 0.009 x year
ci 708 hectares
ii Extrapolated result
5a 3375, 71625, 3375, 68250
bi $3375
ii 4.5%

Just to add to the onslaught of study score questions!
If I got 93,94,96% on sacs with a ranking of about 5
And got
39/40
58/60
What am I looking at?
-
what am I looking at with a
37/40 for exam 1
52/60 for exam 2
and maybe like 7th or higher rank
-
Hey, can anyone tell me what study score I could be looking at? (A range would be awesome :))
SACS: 85/100
Exam 1: 39/40
Exam 2: 59/60
-
My answers. Please let me know if you believe there are errors ::)
-
Are you able to get working out marks for the 30%/25% matrices question if you wrote 0.3*200=60? Or at least half a mark (to a consequencal mark)?
-
This may be possible as it shows that you have part of the working out requirement.
-
My answers. Please let me know if you believe there are errors ::)
Isn't the last graphs and relations question = 9 and 3
-
My answers. Please let me know if you believe there are errors ::)
So there were a few things I got different (could have just been typos you made idk)
DATA Q1bii) I got 975 because 97.5% of 1000 is 975 not 9750.
DATA Q3a) Your value of 46.8 needs to be negative (probably just a typo?)
GEOMETRY 2a) I got 8pm Wednesday because you need to subtract 2 hours to account for the fact that they said the two places had a time difference of 2 hours, and the destination was further East so you would have "gone back in time" *I don't fully remember the question though so I would ahve to read it again to be sure.
GRAPHS Q3d) I got 9 and 3 because you can't just simply round, you have to look at the graph and find the integer (whole number) solution points near the corner point that gives you the minimum. This point was (9.6,2.4) and the two closes integer points that are INSIDE the solution region are (9,3) and (10,3) however (9,3) will obviously give you a smaller value than (10,3) so that's why I wrote that instead :)
-
Isn't the last graphs and relations question = 9 and 3
Yeah I got that as well :)
-
Guys thank you for your replies. Yes last Graphs and Relations answer is 9 and 3 as this is still within the feasible region and provides the minimum cost. Core question 1bii is 975 as I added an extra zero and definitely -46.8 for Q3a. ;)
Thanks
-
Hi guys,
I was wondering if you can help figure out what kind of study score I will get for further. I didn't find the exams hard at all and am ranked 2nd in my school.
- exam 1: ~38/40
- exam 2: about 56/60
- Sacs: 91/100
*edit: thanks Paolo

Hey, I was wondering what study score i can expect for further
My exam 1 score was low so i'm not sure that I can still achieve a 35-40 study score
Exam 1 26/40
Exam 2 52/60
SACS 84/100
Thank you!

If we had [0 1 1] as an answer, would that be considered wrong. And also for the question which requires the total number of students in term 4, if we added values of the initial matrix and added, no one would leave the elective activities, would we still be awarded full marks or did we have to create a transition matrix and find values at term 4
Thank you
-
Hey guys,
I am kinda stressed because I wrote the whole exam in pencil when it says write in blue or black pen in the front of the exam page.
Will my exam be unmarked??? :-\ :-\ :-\
-

Id say theyd mark the [0 1 1] as correct because despite it being contradictory to the written statement its the only matrix that made the equation provided true.

No no! Don't worry they will definitely mark your exam! I had a friend who wrote theirs in pencil last year and they still crushed the exam! The only reason they get you to write in pen is because they scan them or do some part of the marking electronically and pencil can sometimes not show up. I'm sure you're not the only one though and I most definitely would not stress about it. It probably happens every year so they know how to deal with it :)
-
For the question which requires the total number of students in term 4, if we added values of the initial matrix which equal to 750, and then added to the answer: "no one would leave the elective activities" would we still be awarded full marks or did we have to create a transition matrix and find values at term 4
Thank you

Thank you
It's only one mark, so I think just as long as you write the correct answer "750" it's totally fine. My reasoning to the answer was the same as yours but I checked it with the values in Term 4.

SAC mark 98/100 (equal 2nd in strong cohort)
Exam 1 39/40
Exam 2 59/60 (unless 749 is accepted for matrices 2c)
What study score would I be looking at? Is it 45+?

Also, how do you calculate/predict your study scores?

100% 45+ and probably minimum 48... be sure your safe for a high study score

If I received 86-87% for my sacs (whilst being ranked 12 or 13 out of 85 in a strong cohort), 35/40 for exam 1 and 57/60 for exam 2 what study score would I be looking at.

probably low 40s high 30s given that you dropped lots of marks in exam 1 but that exam 2 mark might push you to the 40+ range.

Would 98/100 in Sacs and Exam 1: 38/40 and Exam 2 59/60 get me 45+???? My teacher told me today that there is no way im getting 45 with these scores.... and im super worried now....

the A+ cutoff was 76/80 last year and to get 45+ you need high A+ in both exams. Unless the A+ cut off would be decreased sue to the difficulty of exam 1, I think you're teacher knows what his on about. Don't worry, you never know what could happen at the end
