I still need answers to those, even if they seem ezpz to you I've forgotten to solve those so they aren't ez for me..

Q10 part d i) ii) iii)??

 

[Maryum7]

Can anyone explain how we're supposed to answer Q11(c) and (d)(ii) from this paper? :3

question 1 part b
question 2 part d help me with tangents
question 3 part aiii how to do it! and part b ii
question 6 part c i and d
question 7 part b
question 8 part aii and iii
question 10 part b iii and d

q 1 part b -> 15-4 = 11
11/4 * 100 = 275%
q 2 part d -> do the graph, draw a tangent at 0.5 then use rise/run method to find gradient
q 3 part aiii -> percentile is percentage of the total frequency.
so 80/100*200
q 3 part b ii -> x/200 = 0.3
ans = 4
q 7 part b -> use simultaneous equations
q 8 part aii -> find x from the previous question. it's an isosceles triangle so base angles are equal, find base angles.
q 8 part aiii -> do 110 - angle CBD you get 79. ADB is an isosceles triangle so you find the same base angles.

THIS IS EASY !!!!!
WAIT A MINUTE I' LL POST U SOLUTION !!!!!

You havent replied yet with the solution!

 

[Evangeline]

please how to find the height of a bar in a histogram if another is given. For example:

 

[DeadlYxDemon]

Cant find the values! I tried the formula given by them, but ans is quite different! as i tested it with the first value of "x=-3" i got 9.1 but actually is 9.6

As stated in the diagram that triangles are equal.
Therefore: apply cosine rule to find OP^2, in this way you'll find the length of OP^5.


For d(ii) apply sine rule for O.
i.e p^2Op^3 = P/H
O = 1/ answer of (c)

It's okay
Let me know if you got the correct answers or not?
