Mathematical Methods CAS Exam 1 Discussion - How was it??

[paulsterio]

what would A+ sacs, 35/40 exam 1 and 75/80 exam 2 get you?

Around a 43-44 I'm guessing

[Hamdog17]

So say I got 33-35/40 on exam 1 today and destroyed tomorrow ~76-78/80 what raw study score would I be looking at? (assuming exam 1's cutoffs are a bit lower)

Exactly in the same boat brother. Probably 43-46 for us

I tried to stop myself from posting here but anyways, relax guys just take some time of and have a break and stay calm for tomorrow's exam, since the fact that so many of you guys are even on this site means that you all did better then most of the state.

On an aside @Hamdog: you're probably looking at 43-48 assuming exam 1 cutoff is lower this year, mainly based on some comments on this site.

for the domain question, would you still be right in saying:
R\ (-8,-2) ?

This is mathematically incorrect. You cannot mix set notation with interval notation. The correct notation is R\{x: -8<x<-2) or (-infinite,infinite)\(-8,-2) or (-infinite,-8)U(-2,infinite) or {x:x<=-8}U{x:x>=-2}.
Dr He. told us a story of a chick from MacRob that made this error one year in Methods and lost marks. He also suggested that it was because of these marks that she didn't get 99.95 because she got 99.90 at the end.

Awwwww man, dam it. The essentials textbook uses it! Why the hell did I choose to follow the stupid textbook. There goes a mark, lets hope the assesors are being lenient, although they probably won't be. On another note BRING ON EXAM 2!

there goes my 40 raw dream, I made so many little errors, think i got 35/40, or 34/40. shattered, feel like crying

My friend, Luffy, ended up with 35/40 for Exam 1 and he got a 47 Study Score, so it's possible to get a very good study score with a 35/40, just remember to keep trying and use this as an impetus for trying to do your best in Exam 2, it's best to give Exam 2 your best shot!

considering he got full marks on exam 2..

[mimi123]

wow, jesus, just left out the important part 100 percent on exam 2... wow

[Ilovemathsmeth]

Anyone want to upload the exam ?

[luffy]

Just did the exam for the 'lolz'.

In all honesty, it wasn't too difficult. I would much rather have preferred this exam over my one last year. There was no real student "distinguishing" questions in my opinion. Perhaps the last two questions may have done the trick. The exam favoured students with a strong sense of algebraic manipulation, which was great!

Nonetheless, if you didn't do too well, note that I got 35/40 for exam 1 last year and hence can still get high 40's. Best of luck with exam 2!

where'd you get it from?! :O
btw, how'd you find it, our second last and last questions were on par with the "cone" question right?

Re: topic

I'll be happy with 40 raw after my performance, not good

btw, how'd you find it, our second last and last questions were on par with the "cone" question right?

Nah, cone q was much easier and harder to make a silly mistake in imo

Our spesh teacher (Ms. Callow) lent me her copy so that I could do the exam and go over the solutions with her/other students.

I disagree - I would much rather have preferred those two questions than the cone. The cone had a "trick" to it, in which if you chose the wrong two triangles, you were somewhat.... "unable" to figure out the right answer. (or maybe the pressure got to me... meh). Your last two questions were straightforward algebra manipulation. If you made a mistake, the error was simple to pick up.

Hence, in my opinion, the cone was worse (But remember that my opinion is biased). Nonetheless, a fairly interesting exam.

well you obviously smashed your sacs and exam 2,

[luken93]

Well iTute is standing with 0 < p < 1, and I'd kinda tend to agree with what they say.

If this is the p=0 question. I disagree with itute. Here's my case:

1) Bias = Show prejudice for or against (someone or something) unfairly (google source). Hence, the prob of one event may be diminished to = 0. The coin may have two tails for example, that's realistic (more realistic and do-able than 75% heads in any case).
2) p=0 satisfies the other parts of the question as does p=3/4.
3) Never does it say in the q that a head actually occurred, it only asked the "prob" of it occurring, inferring that it may not happen at all. (I may stand corrected on this point though, I don't have photographic memory).

Although, I did quite badly, so my answer isn't the be-all-and-end-all for this question. VCAA should accept both if they are logical.
