    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
    thats all I got
    Think u got 18a). Wrong I got 2 and a fraction because it was 15 then tines that by 2 reminder what u minus

    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.
    ah **** i thought it said does rAIN and get cancelled ****

    Questionnaire question-
    Wants to know how many crisps people buy
    His question-
    How often do you buy crisps?
    Choices were- often, sometimes and never

    What is two things wrong with this question?(2)
    Design a suitable question(2)
    He asked people in his maths class why may this not be a good sample?(1)

    Is there a google doc being uploaded or are people literally just writing their answers on here? I can't see an attachment. If there is how do I download it?

    Yes the mixed fraction should be 2 12/15, that's what I did at least.

    It must be in exact form which just means surds. It doesn't need to be an integer value.
    I managed to wipe out all of my surds because of using Pythagoras multiple times… slightly concerned but it was only 3 marks I guess ¯\_(ツ)_/¯

    I did 0.8 x 0.95 and got 75% as my answer. Was that right???

    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
    Can't the question about point S also be about how S splits the line OT into the ratio 3:1 (i think it's line OT, cant remember which line. i mean the one that we hadn't already been told about by the paper)

    The question said "what is the probability it does NOT rain, AND it gets cancelled" though? So it was 0.8*0.05=0.04
