What did ppl get for the volume of torous?
and the ratio Ps d : Pm?

And question 6a) ?? i got b=0 ... cant remember the rest

volume i got like... 4 * a * b^2 * pi^2

Yeah i got something along those lines.

i got b=2 not b=0. But a cppl of other ppl said b=0. Can u explain it?

Q6 was easily the hardest in the test that binomial was fucked. And i fucked up the volume as ai spent 30 minutes trying to get rid of the b's and a's as i didnt see that they were constants so massive loss of marks there.

for torus i got 2 x pie ^2 x a x b ^2

Yeah i believe i got b-2 , didn't get any 0

What did people get for the probability question?

i got the ratio as
1:2:6 i think

for the torus i got 2(a)(b^2)(pi^2)

yeah same - i hope that's right! i usually do completely the wrong thing in probablity! and u know how it said assuming n is v large - well i didn't have any n's in mine to start with. assuming that's wrong then?
i think i had ratios as 1/9 : 2/9: 1/6 and then simplified.

what did people get as the eventual elephant population ? i don't remember exactly but it was either 21000 or 2100 or 7000... haha that's helpful

and the rate of growth i got 10%

what was question 6a?

eventual elephant population was 3000, just insert t= infinity into the formula, i hope u guys are right about the ratio being 1:2:6, cause thats what i got, its strange how so many ppl had problems with the probability and didnt attempt, that was probably my fave part of the course :uhhuh:

pop today - 2100
predict - 3000
growth - 10%

vol torus - something like 2ab^2 pi^2 u cubed

limiting value of the sum of 6iii - r / r-1

for the prob question im almost 100% certain its

1:1:2/3 or 3/2 (cant remember what i wrote)

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

the answer is 4pi^2ab^2

=]

I know for a fact because they tried t trick you and you had to chang h^2 into y^2

well done i got the same answers as you.

but see the growht it was actually 9. something percent.

also limitin value i didn't understand jack..

but i got the 1st part and second part right.
