The answer to the first part is 1/x + 10/x^2 + 1/(10-x)
Cannot do part (ii) please help!
No problemthanks alot aleezay
in part i we got v= 40 + Tsin25 and x= Tcos25http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s12_qp_42.pdf
Can anybody please help me with question 4 part ii)?
in Q5bii) it says that either the male cousins will be selected or they will not it doesnt specify about the boys that are left so they must be included in the equationhttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_w09_qp_61.pdf
Q5 b(ii) why we are taking 11C+11C3 instead of 8C5+8C3 wont it be the same then if the question asked for random selection
and can someone plz explain Q6 also
Please answer this questionFor a biased cubical dice the probability of any particular score between 1 and 6 (inclusive) being obtained is inversely proportional to that score. Find the probability of scoring a 1.
what i thought at first thought but i dont know if it is riteI don't know .. I think this is what it will be... What's the answer?
1 ----- 2 ----- 3 ---- 4 ---- 5 ---- 6
x/1 + x/2 + x/3+ x/4 + x/5 + x/6 = 1
49x/20 = 1
x = 20/49
Probability of 1 = x/1
= 20/49 Answer
ii seems correct as all it required was a graphhttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s10_qp_12.pdf
Please help me with qn no. 11 (ii & iii).
I've tried to sketch the graph (Attachment)... please check if its correct. For (iii), I'm totally confused!
Thanks
For ii, the answer is k < 1, k > 7ii seems correct as all it required was a graph
iii basically it is asking for for those values of k for which the line y = k does not intersect each other so k>2 k<-3
plz help me, im terrible at mechanics.
