What was question 7 which answer was a coordinate (-3,-2) I think? Like what was the q about ????


It was something like 'M is the midpoint of PQ. M and Q are shown on the graph. What are the coordinates of P?'
I'm pretty sure Mwas at (1, 2.5) and Q was at (5, 7)

It gave you a line, with the mid point and the co ordinate A which you had to use to find B.

Was it in a graph? Like find the midpoint of 2coordinates? Thanks

It was looking for the angle near the bottom yes, touching the tangent and the right side of the triangle

On the right side of the triangle not the actual base of the triangle though right?
what was the answers to the question with the graph and quadratic equations?
Would I get the marks if I factorised it? For the envelope question?

Yeah, you had to do 1 - 4 = -3 and 2.5 - 4.5 = -2
(-3, -2)

the percentage question was 36%.
the number of females were 11.
the shaded area in a square was 100-25TT = 25(4-TT).


Yeah for the shaded area question I got that as well but didn't know if the "simplest form" was the factorised version or just 100 - 25π ... are you sure we were supposed to factorise it?

My maths teacher predicts a harder calculator paper to follow...wasn't to bad though, I I got reckon 62-70 marks


Can u send me it or something or tell me the topics
Q on vectors (towards the end of the paper)
a) a+b
b) 3b-a (think so, don't remember)
c) 0.75(a+b)
d) S is the intersect between PR(?) and OT and S lies on OT such that OS: ST = 3:1
the solve equation one was 3x=-6 which went to -2 i think, i hope

Standard form was 3.5x10^something / 5x10^-3 it comes out to 7x10^8
The questionnaire responses can't have overlapped


The possibly answers included:

No time frame
Answers to vague
Lack of option etc.

Couldn't really be overlapping providing the fact there weren't any numbers in the options?
******
Anyone want be to do the predictions for grades under an A?..
What about the question where the answer is W=1.4 or 7/5

Doubt you need to factorise it mark scheme will probs say 100-25TT oe (or equivalent)

Wasn't the probability tree 0.8 x 0.95? Some people are saying 0.8 and 0.04?
Can someone remind me what Q18 was?


the answer is 0.04
