23) was 3-x/(x-3)(3x-4)
2. (Original post by MovedMasterMike)
I got 10 because you can't have 10.8 people
So you round it up to 11
3. (Original post by chrisbruv)
it was 3 bars and even if it was 2 you wouldve got it wrong because it said how many bars not half bars so it wouldve been just 1 bar in your case
I asked how did u get 3 pls
4. Thats what i glt
5. For the question with two triangles, I used sine rule and not pythagoras but still got 30.1 (by doing 180-90-59.926). It said that you must show working so would I still get marks? It's technically correct

I got told you always round up to nearest whole number of people in stratified sampling by my teacher, as it works out to be the right number of people in the sample as other classes have 2.2 for example, evening it out.
7. (Original post by MovedMasterMike)
y = 5p^2 - x
yep thats what i got
8. (Original post by muchunknown)
If you round before the final answer u get 80.4 if you are accurate and don't round and keep the sins in the equation you get 80.1
I didn't round until the end but got 80.4
9. could anyone put up the marks for each question and perhaps the question itself?
10. (Original post by junayd1998)
yh i got 3 wow do you think that is correct?
My friends got the same answer. Was that a 5 mark question?
11. If you tell me what each question actually involved, I'm sure I can remember the answers to some
12. I got medium packet too
13. (Original post by Barnewell)
80.4
or 80.1 we are having a school debate, you couldd say a maths debate
Sorry it was the other way round 80.4 is accurate 80.1 isn't

I asked how did u get 3 pls
250000/72960 = 3.892......
You can't have 3.89 bars so he can carry a maximum of 3 bars

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.
