1. That's what I got too I think it's right
2. the one about if Paul and his car losing over half of it value after 3 years was no because pauls car after 3 years value was £7600 (something like that) and 15000/2=£7500

Expansion of (3-X)(-3x-4)=3x^2-5x-12 which is what the bottom was - how am I wrong?

7(c) was not 2.61m. It wanted a 145% increase and 2.61m is only a 45% increase. You needed to find 100% of 1.8 (double it) and find 45% of 1.8. Add these two values together (3.6m and 0.81m) to get 4.41m.
100% isn't double... 100% of something is just it's self
8. [QUOTE=LilyKitty;65592433]I got 80.4 too. 🤗[/QUOTE

Can I ask how you did your working out because I got 40 degrees and it's really bugging me.

The question was:

All the angles are acute
one length is 7cm, one is 8cm
the area is 18cm^2
find the between the two lengths.

I put 80.38 not sure if that's to the right degree of accuracy
The question asked for 3 significant figures so the answer was 80.4 you'll prob lose 1 mark

Expansion of (3-X)(-3x-4)=3x^2+5x-12 which is what the bottom was - how am I wrong?

14. there was a cubic graph question that was like x^3-3x+1 for -2 to 2

Ahhhhhh that's going to annoy me forever especially if I miss out by a mark or two. Oh well it was only out of 2 wasn't it so I'll get 1 for the working?

No I'm certain it was 0.45 becase 9 people out of 20 got below 28
Do you think you'd get a mark with putting 9/20?
19. (Original post by Cakes717)
What was the answer for stratefied sampling? I put 10 students...
10 or 11 is right
20. how many marks was the first question on probability? the answer was 9/20?
