Question 5-6 (2 Viewers)

[duy.le]

What did people get for the other parts of the probability, not the ratio?

i remember i got something along the lines of:

(x+1)(x-2):x(x-1):2/3(x)(x+1)

please dont quote me on that, i cant remember my exact answer, ill do it again later. but if u let x -> infinity

x+1=x

duy.le...

how many questions did u leave out.

man i was so no happy with that paper.

what will a raw mark of approx 70% will get you.

 

[duy.le]

i didnt leave out anything, but that doesnt mean i was able to do everything i attempted everything such tath i will get atleast 1 mark for them.

i actually dont know what a 70% will get you for this test. cause u guys are like top 10-20% of the state and u guys found it hard so...cant tell how the state found it, presumably hard.

so 70%-90 mayb

man i hope soo...

my internal mark is in the 90's *cries*

Nah mate, the answer for the torus is 2pi^2ab^2, not 4. Try doing it again

got destroyed by question 6; the binomial, the polynomial and the final part of the conics question. 3/15 for q6.
