Math Advanced Prediction/Thoughts (1 Viewer)

[hellohowslife]

I can’t decide whether the exam was way harder than last years or whether I can’t math in exam conditions.

that was like 10x harder than last years imo

Doesn't sound good based on the thread so far ... what were the hardest topics in the exam?

I thought so, you thought they’d make it easier too but nah

 

[Greninja340]

wait was there no max min problem? Or did I just miss a page?!?

the maximum height one and the mode of the Cumilative frequency graph both had maximisations

test was a bit harder than last years, but not crazy. They really abused the shi out of statistics in that paper tho lol

Guys if you want to feel better just go to the HSC fb discussion group

idk i didn’t even read some of them cos they were so mf long and they didn’t make sense, like damn i thought this was a maths test not a reading comprehension test?

you had to find the height of the male

from the data of the females

my only redeeming quality in this exam is that i remembered to divide the sphere by 2

but yea still not that confident haha

 

[stressedadfff]

understood all the concepts in all the questions but might've made silly mistakes

Tf was the last one then???

the probability of all P(X=x) equals to 1, it was a geometric series, sub, simplifying it gives you which equals to part of answer which I forgot. the expected value can be found by multiplying X by P(X=x), and every column equates to from memory, for a total of n scores, the expected value would be

then you sub the value from the sum for which proves it

Omg I put that formula down and subbed in the values but didn’t make it equal one you reckon I could get one marks…?
