I factorised the letter one (t=5x+20y) will i still get the mark if thats right??

Probably not. While it still works, they didn't ask you do to it nor is it in the "correct" form.

You know for the crisps question where is says why is asking students at a school not a good sample.

Would this answer be ok:

It is not a good sample because asking students at a school is not representative of all people.

My predictions for grade boundaries (I've tried to look at the jumps between 2010-2015)

A*- highest the boundaries could go: 165-168/200
A*-lowest grade boundaries could go: 160-162/200

It is unlikely they will keep it around 155 like last year my personal thought because the test was doable

A-highest the boundaries could go: 133-136/200
A- lowest the boundaries could go : 128-132/200

The boundaries will usually go down by 30-35 for each grade

Yes the sample is too small and bad representation

another part of Q3 was: the sample was taken from students. Why is this a bad sample group?
i put because it would not represent everyone as it is an unvaried sample group.

I think it means it should be completely accurate so you have to leave it as a surd

Hey, if anybody is willing to contribute the answers, and preferably the questions, then I shall set up a mark scheme for you all. Thanks in advance!

Can people please attach question numbers to their answers? Method would be appreciated.

This will be updated as I go along.

Would i get method marks, i did get the correct answer, and wrote it down, but i put the factorised version in the answer box thing.

From the surds question i've seen.

ABD = 1/2 x rt2/2 x rt2/2 = 2/8 = 1/4

ABC = 1/2 x rt3/3 x rt2/2 = rt6/12

ABD - ABC = 1/4 - rt6/12

You can't do 100-25pi without multiplying out the Pi first. BODMAS.
