i believe 8 is supposed to be C and 10 is D

hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
are you sure? it says 'at least one'. I thought multiplication is for when all of them are true. I added them together to get a as it is EITHER of those probabilities.

yay skimming over those solutions i did pretty much did the same thing =)

For the bearing question, if you did the bearing from A to C instead of C to A, would that be a straight 0/3? Can't believe I did that...

And also just for curiosity what would a raw mark of ~90 align to?

I did the same thing for bearing... anyone have an answer to this?

My predictions were correct, Q 15 will be the hardest section

considerably, i mean q 16 was just full of 'show' this and 'show' that and they just chucked in a simple integration question and a slightly harder simpsons rule and a 'bit' more complicated r value (1.01/1.003) for the deposit part

How did everyone get 337 for the angle!

You get 0 since it was unnecessary to calculate that angle.

90 raw will align to 92-95 depending on the cohort's performance.

wow. i skipped part ii and iii - and im luck i did

1. A
2. B
3. D
4. C
5. B
6. D (burnnnnnnnn put b! Why?!)
7. C
8. C
9. A
10. D

No band 6 4 me.

I probably put D as well. just didn't recall properly
Are you sure that 10 is D? I thought it was A

P(at least 1) = 1 - P(No one wins) = 1 - (3/4 X 5/6 X 3/5) = 5/8

 

[Technoash]

P(at least 1) = 1 - P(No one wins) = 1 - (3/4 X 5/6 X 3/5) = 5/8

Thanks. I was wrong

Thanks. I was wrong

Yeah. Don't worry, 99 is better than nothing...

Lol I cant factorise that cubic so let us burrrrrrrnnn

Yeah lol me neither. I literally just had to expand them all to get the answer!! haha i was scavenging for marks whereever i could

can someone post the working out for the superannuation question

 

[Simile]

16gg , prone to silly mistakes and forgot, that you could do the maximum/ minimum question without doing th questions before! What did you get for k in the equation and the part I of the drug question

 

[rose_maylie]

yes. especially the exponential graph and tangent question. 16 was uncharacteristically easy :/

Anyone else find q15 much harder than q16?

part i) i just went screw it and put 10/3 + 10. it's wrong 99% sure

I'm curious about question 13 b)ii too im sure i got it wrong

 

[rose_maylie]

omg yes i got this!

Fuck you point p
also, fuck A, A1, and A2


was 16 c iii) x=1.5 and y=2.3?

 

[hublay]

Ye what the hell was the working for that superannuation question.. some please post.
