P3. Log question. It was to find value p and value q.
The value of p was like 550. What did u get for the value of q? Was it like 0.8 or 1.2. My friends are discussing which is correct.

do you remember the coordinates of the modulus graph? ...i got (-7/2, -10) ...
what was your range of the composite function ff(x) ..mine was 5 to 22

Hey, I'm taking FP2 and S2 too! (and S3) How did you find FP2?? It was more difficult than the past papers for me. Do you want to check answers if you remember them? I wrote down the questions in the pdf attached. Good luck with S2 today!

fp2 was the toughest in history of further mathematics. i messed uu like 15 marks ....man you are a genius , don't remember all the answers but your answers seem to be correct and you will end up getting full ums for sure ..i am really curious what do u eat ? i feel so stupid compared to u , prepared for full ums but got f**ked by this paper.

S2 was easier than I thought!
Someone asked for the pilot and last question in the other thread, so I wrote it down here as well
120 (?) was n and 0.045 was p
- Binomial to poisson approximations with landa = 5.4
- Exactly 5, so should use the poisson formula
96 was n and 0.75 was p
- Binomial to normal approximations with N(72, 18)
- Two tail test at 5% sig level (as no direction given)
- 67 is in the lower tail — probability of smaller than 67.5 was 0.1444 smth which is greater than 0.025, so accept H0

This was the last question for S2, in case anyone's curious!
Where A~U[10, 30], I did L~U[root 10, root 30]. L is one side of a square and A is the area.
Find P(L>=4.5)
- L^2>20.25
- (30-20.25)/20
Find Var(L)
- E[L^2] is just (10+30)/2
- For E[L] — should have integrated L/(root 30-root10) with root 30 and root 10 as limits
- I got 1.44 smth for the final value, and checked with a few of my classmates!
