i think i got A for MC 3, E for Q22
For short ans:
1c) u can simplify cube rt(500) to 5 cube rt(4)
2a) m = 8000
2e) i got an exact ans of 2hr 40min
2g) i think 3s sth?
rest of short ans should be pretty much the same..

You are sooooooooooooooooo lucky!! i have 2 exams left sigh

omg fuck i just realised i made the stupidest mistake EVER
for the amount of time its undr 1250.. my x values were like 28/3 and 32/3 or something like that.. anyway i counted that gap as 4 hours. instead of 4/3 hours! which x2 would have been 2.666 which is 2hr 40 mins which is right but instead i put 8 hours cos i copeltely was NOT thinking. FUCK FUCK i hate stupid mistakes

cubic equation
y=-2x^3-6x^2+2x+6

ps. um wait, what was the difference between the cas and normal exams? cos all these questions you speak of seem to be ones i did in the cas exam? so confused
-
i got 1.337*2 for total hours .. so it about about 2.67 hours overall .. so i think i got that right ... please let it be haha - i think i did write 2 hours 40.2 minutes ..is that okay for an answer?
btw, hifer- with your 3 seconds. did you get it because of the 1.337 hour interval, before the concentration hit deadly again? cos i got like 2 . something seconds, but im not for sure what i got numerically

I got exactly that
cubic equation

Did we have to expand it? I left it factorised
-
i used my calc to solve it.
hrm. its 160min isn't?
-
^ 160 minutes is 2 hours and 40 minutes ...
160 divide by 60 is 2.67 .. .67*60 is 40 minutes.
so yes, we are correct

ya.. i couldn't really rmb it was 2 or 3 sec i guess

but i think for some reason i wrote 180 minutes. :S oh well. there goes 1 mark. lost about 2000000000000 marks. LOL altogether...

Did Indiana...i mean, Tasmania Jones escape with 3.75 seconds remaining?
-
what study score do u think u got? anyone leave any qstns? i left last part of "deadly qstn" and last page of exam.
-
Did Indiana...i mean, Tasmania Jones escape with 3.75 seconds remaining?
indeed
-
lol, that's heaps of time. Indiana Jones only had about half a second to escape from that boulder thing.
-
lol, that's heaps of time. Indiana Jones only had about half a second to escape from that boulder thing.
I think I got even less than half a second?
Either way, that was a stupid question. :P
-

lol i think he is talking about INDIANA jones (i.e. the movie character) not TASMANIA Jones (the poor-man's Indiana Jones from our exam)

Lolz :P
But still, I got some very small value for the stupid guy from our exam...
-
What did youse guys get for the last probability question.
Max value of 'p' and 'q'
and : the value of 'b' at which it occurs
-
p=10, q=1.5
cannot remember b at all. honestly, i can barely remember the exam at all, soon as i walked out it seemed to disappear from my mind.
time left for tasmania jones (tasmania really is a girl's name i'm sure): 3.75 secs
-
lol
No I meant 'p' and Q
from last question.
But thanks anyways.

hahah told ya i can't remember the exam :D
-
Yeh I do not blame you there. :P
-
I am waiting for itute to post up their solutions.. :twisted:
-
i got p = 0.5858 and Q.... cant quite remember
-
i got p = 0.5858 and Q.... cant quite remember
why look who it is, the chris killer :shock:

Oh, Holly Shit
I just realised something.
Stupid me got 3.1414 for the probablilty, after getting the other maximum point(my calc did not show other max at 0.58).
:x :x :x :x :x :x :x :x :x :x :x :x :x
And so I got the wrong value of Q
And so I got the wrong value of 'b'
DAMN!!

what value for b did u get? i hope we are talking abt the very last qn...i got b= 20.9
-
now that i remember it i believe i got something close to p=0.5858 and q=0.5887, or some very very similar. i felt it was a little wierd that they were so similar but meh hahah. and b=20.9 does sound familiar too i think i had that.

gee iTute is quick: http://www.itute.com/mathline/2007_vcaa_mm_exam2_sol.pdf
According to those solutions and my poor memory, i lost 2 - 5 marks. I'm content with that

nice man! i think i lost at least 6marks...(2 from multi choice and 4 from short answer)

even better!

Looking at the solutions, I don't think I did as bad as I first thought, still bad, but not as bad.
Can anyone remember how many marks the following questions were worth...these aren't the one's I got wrong, I can remember most of the other mark allocations, I've just totally forgotten how much the following were worth...
2g, 3a ,4d, 5fii

what value for b did u get? i hope we are talking abt the very last qn...i got b= 20.9
I used Probability =0.03044(from previous question) , and so got the wrong value of b(like 19.2 mins or something like that) . I hope I get consequential marks, because I did write down an integral.
From the solutions it seems I lost:
1 mark in Tassie Jones
2-4 marks in final part of prob question.
-
2g, 3a ,4d, 5fii
4d) was worth 3 marks
Not sure about the rest thought. sorry

When, where and how do we access our Methods Results?
-
When, where and how do we access our Methods Results?
December 17th.
Online, SMS or wait for the mail that is supposed to arrive on the 18th.
-
When is it published in the age?
-
some are in the age
access in VCAA on 17th, or u can set up sms or call them but that cost money...
they mail it 2 u on 18th to ur door (if u checked ur address with school and VCAA and it's right)
yeah... check on VCAA website for more details
-
I think above 40 scores are published in the age/ the herald sun on the 18th.
-
Yeh
Results are out on the 17th at 7 am from VCAA

Yeah, unnecessary post-count inflation is annoying. I don't mind pointless posts, but when you have people (no names mentioned, because I can't actually think of everyone who I've noticed doing it) who post in every thread they can find, and bump up heaps of topics, it makes for really boring reading, and that sort of stuff keeps me away from FSN for a couple of days sometimes.
