    Yeah I got all the same answers. Does anyone remember what they got for using the graph to estimate the x^2+4x-2=0 etc.
    I got -0.4 and 4.4, and -1.1 and 5.1 (I think!)

    Then for the simultaneous equations I can't remember the numbers but I think there was a 4.7.

    the percentage question was 36%.
    the number of females were 11.
    the shaded area in a square was 100-25TT = 25(4-TT).
    The simplified answer is 75TT because TT is a number not a variable

    Was the vectors question 3/4 a + 3/4 b
    and then the part that was like what does this tell you about point s
    the answer would be that it is 3/4 along the line PT
    im not too sure :/

    was the answer to the standard form question 7x10^9
    i think the question was (3.5x10^6)/(5x10^-3)
    i think.. dont quote me on that
    i put 7x10*8

    Agree. Reckon the grade boundaries will be 99 for an A*, 98 for an A, 97 for a B, 96 for a C ahaha

    Q?? - Estimate 892/18.9 (or something idk) (2 marks - maybe)
    Round to 1sf
    900/20 = 45

    Q?? - Angle = 69 (4 marks [I think])

    180-48-48 = 84 (angles in a triangle sum to 180 & base angles in an isosceles are equal)
    84/2 = 42 (angle at the centre is twice the angle at the circumference)
    (180-42)/2 = 69 (angles in a triangle sum to 180 & base angles in an isosceles are equal)
    Therefore angle = 69 (alternate segment theorem)

    Q?? - Angie does not have enough varnish (5 marks)

    Total area = (4x10) + (2x2.5x2) = 50 metres squared
    Litres required = 50/5 = 10 litres
    Angie has = 3 x 2.5 = 7.5 litres
    10 litres > 7.5 litres

    Q?? - find shaded area of triangles in square= 25(4 - π) (5 marks)

    Square = 10x10 = 100 cm squared
    Circle = π x 5 squared = 25π
    Shaded = 100 - 25π = 25 (4 - π)

    Q25 - find the shaded area = 3 - root6/12 (3 marks)

    (root2/2 x root2/2)x 1/2 = 1/2 x 1/2 = 1/4 cm squared
    (root3/3 x root2/2) x 1/2/ = root6/6 x 1/2 = root6/12 cm squared
    1/4 - root6/12 = 3/12 - root6/12 = 3 - root6/12

    That's all I can remember for now
    for q25, would it be fine if you left as

    1/4 - root6/12 ??

    someone talk about the vectors question
    a+b
    3b-a
    3/4(a+b)
    Therefore S was on OT because 3/4 is a scalar of the vector a+b.

    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
    How did you get 1.7 and 4.7. I drew the graph of x+y=6 so (y=6-x) and I wrote down the points of intersection

    Correct, I got for A -0.4 and 4.4
    and B -1.1 and 4.7ish I think around there, it was <5

    would 85% be enough for an A*??
    Yes, 85/100 is the boundary for an A* however this might increase or decrease based on how well the nation did as a whole

    No. Was 100-25pi simplifies to 25(4-pi).
