They are parallel because vectors are quantities which represent magnitude and directions, hence multiples of the same vector are parallel.

2. 12(b) was 9
3. No, it asked for ED not the total length, so it was 9-4, hence 5,
For part c of the final question, I believe you needed to state OP=2 QR or vice-versa to make it clear that you'd answered the question.

22b) it has to be a multiple of OP=p and it is 1/2p so it is parallel.
5. I think for part b of the Venn diagram question it was 5/9 and not 9/64, as it asked the probability of the students who both owned a desktop and a laptop to also have a tablet.

Wasn't Q1 3n+7 because the sequence was 7,10,13,16,19,21 etc?
7. (Original post by Dr Carlsberg)
Wasn't Q1 3n+7 because the sequence was 7,10,13,16,19,21 etc?
If it was 3n+7 the first number would be 3(1) + 7 = 10, with the second number being 3(2) + 7 = 13
8. (Original post by James the 23rd)
I think for part b of the Venn diagram question it was 5/9 and not 9/64, as it asked the probability of the students who both owned a desktop and a laptop to also have a tablet.
I agree.

OMG yeah, well that was stupid of me Thanks for explaining though!
10. I think 13 a) was 4p^3 if memory serves correctly.
11. (Original post by UmbralArbiter)
I think 13 a) was 4p^3 if memory serves correctly.
I think it was 1/4 (0.25) as you had to cube whatever p was and then M (or whatever the other letter was!) was divided by that

Can anyone remember the question that was like (2x - 5)^2 as part of it... I think I messed it up!

Was that the difference of 2 squares one? (With x^2 -25 on the top)

Also, can you remember the 2 values stated for M and P?
14. that last functions question though wtff
15. With the Venn Diagram, the other result as well as (4, 4, 6, 2, 5, 6, 2, 3) was 2 on the outside so that the total was 32 students
16. For 21, most people I've spoken to got 5/9 as in 5 people in the middle out of 9 people with laptops, desktops and/or tablets? Anyone else get 5/9?

Yes.
18. Doesn't Q 6 have a second part, where they ask about the original price during the sale?
19. Wasn't 16c 1/4?
20. (Original post by zaggalicious)
Doesn't Q 6 have a second part, where they ask about the original price during the sale?
Just times the stated value by 5 (or something similar)
