    No. Was 100-25pi simplifies to 25(4-pi).
    my friends got 75 pie but i had 4- pie so who is right?

    [QUOTE=LogicalFallacy;65190495]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.Any ideas for the finding estimates for the graph one? There were 2 equations and then the simultaneous one I think..

    I said 75pie as final answer but that is wrong i think because it is not 100pie - 25pie

    fml got the right answer at first as 100- 25pi but then decided it was wrong and crossed it out and put 100- 10 pi.. Sucks, I'm normally an A* student and pretty sure i barely got an A
    Is that its simplest form? I do hope so

    X^2=4 (x-3)^2 solutions were 2 and 6 by creating a quadratic and either solving or factorising.

    First one was 750 cm^3

    90teachers

    36% on rent

    150 students over £130

    100cm^2 -25 pi (I factorised to 25 (4-pi) ) for the square with circle in it

    she does not have enough varnish, she needs 4 tins and only has 3


    As much as I can remember so far, will update as I remember hope all went well for you guys

    Q1 750cm^3
    Q2 too vague and no timeframe
    The class is a small sample/biased
    Q3 p^7
    g^2
    k^6
    10-5m
    n(n-7)
    45
    90
    No not enough varnish cos she needs 50cm^2 but has 37.5cm^2
    60
    T=5x+20y
    (-3,-2)
    11 females
    100-25pi
    36%
    I compared median, IQR and range
    150
    7x10^8
    X<7
    7/5
    2 4/5 in mixed fraction form
    4/5
    x=-0.4 and 4.4
    X=-1.1 and 5.1
    X=-1.7 and 4.7
    Angle MST 69
    Probability is 0.04
    X=2&6
    a+b
    -a+3b
    3/4(a+b) for vector
    Point s is on both lines and it is point where they intersect
    100,25,4
    Final questions is (3-root6)/12
    What was the question that had 60 as the answer? Dw if you cant rememeber i was jw

    what do you think the grade boundary for an A will be, apparently loads of people are complaining on twitter saying it was hard, what do you think?
    Harder than last years or on par?

    Can't remember the question, I think it was solving simultaneous equations on graphs: for the first part I completed the square and got the solutions because I honestly was stuck.

    I typed this answer on google and I'm seeing a yahoo answer diccussi g this question from 2009 what even the questions were really similar to questions I've done before so that was good

    That was a tricky one, everyone at school seems to have different answers:
    Mine being (2 - root 6)/12.
    I think (could be wrong here) that mine was 1 and 30/36. (As in, all one mixed number.) I'm really not convinced it's right though.

    number 4 p^7, g^2, k^6 -5m+10 n(n+7) ( 6 marks)
    number 5 is 45 (2 marks
    number 6 is 90 ( 3 marks)
    number 7 is no ( 5 marks)
    number 8 is 64
    number 9 is T=5x =20y ( 3 marks
    Number 10 ia 3,4.75 ( 3 marks)
    number 12 I got as 75 (3 marks i think)
    number 16a i got 186 (2 marks)
    number 17a I got x<7 b. w=4 (4 marks)
    number 18a is a mixed fraction 4 1/3 b. 32/15 (6 marks)
    20. I got 116 degrees (5 marks)
    22. is x= 4/12 x=-4/12 I am certain about that did question similar to it before exam and it follows same pattern (4 marks

    100-pi is wrong, it should be 25-pi coz they tell you to simplify

    100-25TT

    G2

    P2 x p5

    (K3)2

    Didn't have enough litres

    Solve X2 = 4(x-3)2 =3?

    36%

    0.04 probability

    90 teachers

    Table = 100,25,4

    Idk whether these are right

    No that's the probability that it wasn't going to rain AND it get's cancelled, or the other way around. It was 0.8*0.95 though.
