am i the only one that did 14 b) iii like this

That sort of thing is kind of a gamble on whether there was an implied hence.

However, chances are good it's ok

I fudged a lot of q8 tryna scrape some marks, how much. is needed to get like 1/2 in each part?/

same i made so much up trying to scrape 1 lol

Riuace seems to be the first to do complete solutions. He beat Terry Lee.

The format is a bit strange. Big long pictures. You'll have to zoom in.

Maybe Terry Lee still doesn't have Q6 and 7.

Oh no.. I thought that a score question was 68% cause I used the approximation from the previous question

 

[Trebla]

do u have a solution to 14) a) please?

It's very wordy, but hopefully makes sense...

 

[shashysha]

Oh no.. I thought that a score question was 68% cause I used the approximation from the previous question

is that question wrong? I swear it was P(55<x<65) not P(55<x<60) so the z score should be -1<z<1 which is 68%

Looking at the sample answers, I think my raw marks are 67/70. What hsc mark do you think that will align to?
I cannot believe for the differential equation I did y as a function of x and not the other way around. I'm so stupid lol. But I would only lose 1 mark for that, wouldn't I? But I think its wrong and it is 68% score question as well.

 

[anthony___]

yeah he stuffed it, it was definitely between 55 and 65

Few.... that scared me for a second

honestly i think youre chilling on a 97-98

The vector multiple-choice solution is wrong as well isn't it? Shouldn't it be D and not A, or am I missing something obvious?

They originally went on discord when it became clear that riuace was also missing Q6 and 7. Eventually they found their way to him and he was able to complete his solutions.

They used to let students keep the question papers (the parts where there are no responses written).

Just a heads-up that this appears to be an outdated version of this set of answers.

i feel like that too, i mean his solutions look exactly like A. i just assumed it was D and hoped for the best LOL

yeah, thought it was D too

 

[henry_1234]

For the last part of 14a I wrote the answer at the very start then spent probably 15 minutes trying to simplify it and equate it with part iii cause I thought thats what it wanted, but would I still get the marks for that.

 

[ItzZoni]

yeah, thought it was D too

I think it is D for 6. RuiAce updated the solutions to make 6 D
