GCE A Level H2 Maths Paper 2

jaydunkfull SG

yeah.

i put 120, 9, 175, 7560 for that.

i got 7560 too, but it looked really big

jaydunkfull SG

got stuck at the table tennis question too

secretliker SG

Why is 10(iv) 485?

xXxTaboOxXx SG

Is it : 12C8 - (no diplomats from K + no diplomats from L + no diplomats from M) = 12C8 - ( 9C8 + 8C8 + 0 ) = 495 - (9+1) = 485

deathmaster SG

yeah.

i put 120, 9, 175, 7560 for that.

tennis qsn part 3 i wrong. dang.

but i can tell u tt ur ans for part iv) of the diplomat qsn is wrong.

there is no permutation, only combination, cos here order is not important.

and taboo got the correct explanation.

X1ao-lang SG

yes. that was how i got 485. 7650 is simply too large man.

^tamago^ SG

hmmmmmm L>>

xXxTaboOxXx SG

how to do the poisson 1 the part where they ask why it's not a good model???

deathmaster SG

i dunoe wad to write also. i just randomly say that mean = 90 is large, thus poisson dist will not be accurate.

someone told me after the paper that we r suppose to write that it is poisson applies to rare occurences. so when applied on 50 weeks timespan will not be accurate.

Chocoholicxx SG

poisson is average per week. i wrote that sales flucuate monthly and hence it is not accurate for 50 weeks timespan.

my probability i got (i)0.5 (ii)0.512 (iii)0.109

PnC i got (i) 120 , (ii) 9 (iii)210 (iv) 485

so far.. only complex wrong ): hope for 90s range ><

xXxTaboOxXx SG

oh ya then what is the complex no ans?? for the angles?

^tamago^ SG

i got 0º and 36º.

imba.

xXxTaboOxXx SG

but the question say the argument more than 0 so is it only 36?

DrAlienology SG

i got 0º and 36º.

eh radians leh.

I think my maximum argument wrong, and as for the minimum arguement.. by drawing the argument would be zero. but they tried subbing in the equation for complex numbers, they got a angle very very close to zero, but not zero...

I keeping the faith that this paper can push up my very screwed maths paper 1

deathmaster SG

eh radians leh.

I keeping the faith that this paper can push up my very screwed maths paper 1

to an A?

DrAlienology SG

yeah an A. can only hope for the A.. sigh.

secretliker SG

xXxTaboOxXx SG

yay thks I got that ans too=D

I screwed up my P1 also!

^tamago^ SG

eh radians leh.

I keeping the faith that this paper can push up my very screwed maths paper 1

oh yeah.... shyt. my paper 1 is much better. i suck at paper 2. :(
