    For question 19, I done the correct formula but I think I put 10 males instead of 11, would I get a mark
    Yeah they should both be correct because you can't get that much of a person

    Can anyone tell me what question 21 was asking it's the only question I can't remember and the answer was 29.25 according to the unofficial mark scheme.
    it was that one about the bounds i think, i= 5(v-u) or something

    Honestly if you look at a stratified sample past paper question then the mark scheme is quite lenient usually. They give the correct answer in mark scheme and they USUALLY allow you to be 1 higher or 1 lower.

    This is because sometimes what you work out, if you add all of the values up including your one, the total may be off by 1, so sometimes 10.8 should be 10.

    But they are lenient usually, so I think 10-11 will be allowed.

    Good luck!

    it was closer to 3.7. all my friends, teachers agreed with me. if we are all wrong well thats a bummer because itll mean i got 99/100 in the paper
    the difference is bigger as when numbers increase the difference increases.
    eg. 2 cubed = 8
    4 cubed = 64
    8 cubed = 512

    the exact answer is 3.7504

    I think ur answer will not be accepted because it was 10.8 recurring, since its higher than 0.5 then your ment to round up. if ur examiner is kind ull get the mark tho
    Damn. You see I thought when it came to people you can't round another person as you don't have an extra 0.2 of a person, so I rounded it down :/

    It's 3.8, check any past paper question and read the mark scheme.

    You need to find the solution of x to 1 dp, not which dp is closer to it.

    3.75 is not x, it's too small, so the solution of x is after 3.75 so it rounds to 3.8

    Good luck with the 99 or 98 though!

    80.4
    or 80.1 we are having a school debate, you couldd say a maths debate
    If you said 80.4 you would be correct, I originally got 80.1 but I released I had rounded my calculations during my working out, which you should not do.

    I don't think so because the angle has to be between the two sides (7 &8) for the formula of triangle area to work and x was another angle so you had to do cosine to find another side and then sine rule too before you could get x. Not sure though. xx
    Surely it would be 1/2 ab sinC as the area was 18 and you rearrange to find the angle which is 40.0

    Are you sure about that because all of my top set class got 3.8 myself included? I mean you might be right but I thought it would most likely be 3.8

    --------my answer--------
    (before all this below i did 3.5 and 3.6)
    3.73.7^3 - 5(3.7) = 32.153
    34 - 32.153 = 1.847
    So 3.7 is 1.847 away.

    3.83.8^3 - 5(3.8) = 35.872
    35.872 - 34 = 1.872
    So 3.8 is 1.872 away.

    This shows 3.8 being 0.025 further away than 3.7. 3.7 is closer. Therefore, the answer is 3.7, even though 3.75, the midpoint between them gives an answer smaller than 34.

    Ive done all the past papers from 2003 till 2016 (i sat my gcse this year) and sometimes the exam is lenient and sometimes they wont accept it. I think if lots of people did your mistake then you will get the mark bc ur technically correct in the end
