    How bout the construction Qs how did you do them
    you were supposed to draw the line y=4 then see where they intersect, but i instead moved the entire graph down by 4 then measured where it intersected y=0

    do you think that will still be correct

    Pretty easy, going to be high grade boundaries.

    Depends on how many marks, presuming it was ~4, You'd probably get 2/4

    It was a right angled triangle with the sides attaching to the right angle both being 'square root 2' / 2. Then a shaded portion inside the right angles triangle making a thin triangle on the hypotenuse if that makes sense. The length of the side minus the base of the shaded triangle was 'square root 3' /3. Then it asked for the exact area of the shaded triangle.

    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.
    Spoiler:
    Show
    Question 1. What is the volume of the prism? (2 marks)

    Area of face = 30cm²
    Length of prism = 25cm.

    30cm² x 25cm = 750cm³

    Question 3. What is wrong with the questionnaire? Give two reasons. (2 marks)
    Attachment 538813
    'Too vague (i.e. not 1-2, 3-4 etc.)' and 'no time frame (i.e. not per week, per month, etc.)' are accepted.

    Question 4.
    P2 x P5 = P7

    G6 ÷ G4 = G2

    (K3)2 = K6

    Question 5(?). Estimate 892 ÷ 18.9 (2 marks)
    Round to 1 significant figure

    900 ÷ 20 = 45


    Question 6. A teacher is picked at random. 3/5 chance they are female. 36 are males. (3 marks)
    How many teachers are there altogether?

    2/5 of teachers are male. 36 are male.

    2/5 of total = 36
    2 x 18 = 36
    18 x 2 = 90.
    Answer is 90 teachers.


    Question (?). Solve X² = 4(X-3)²

    X² = 4[(X - 3)(X - 3)]
    X² = 4[X² - 3X - 3X+ 9]
    X² = 4[X² - 6X + 9]
    X² = 4X² - 24X + 36

    0 = 4X² - X² - 24X + 36
    0 = 3X² - 24X + 36

    0 = 3[X² - 8x + 12]
    0 = 3[(X - 6)(X - 2)]

    X = 6 or X = 2

    Question 11(?). What percent of his total spending is his rent now?
    Answer is 36%.


    Question 13(?). How many females visited the art gallery?
    66 students went on the trip.

    Males - Bowling - 4
    Females - Bowling - 6
    Total - Bowling - 10

    Males - Art Gallery - 9
    Females - Art Gallery - 11
    Total - Art Gallery - 20

    Males - Skating - 10
    Females - Skating - 26
    Total - Skating - 36

    Males - Total - 23
    Females - Total - 43
    People - Total - 66


    Answer is 11 females.

    Question 14(?).
    Attachment 538769
    Area of square = 10cm x 10cm = 100 cm²
    Area of circle = π5² = 25π cm²
    Area of shaded = Area of square - Area of circle = 100 cm² - 25π cm² = 100 - 25π cm²


    Question 15(?).



    200 x 25% = 50
    200 - 50 = 150

    Last part, answer was 150.

    Question 21(?). What is the chance of the match being cancelled when it does not rain?
    Attachment 538811
    0.8 x 0.05

    Answer is 0.04.


    Question 22(?). What is the angle?

    Angles in a triangle add up to 180°, base angles in an isosceles are equal.
    180° - 48° - 48° = 84°

    Angle at centre is twice angle at circumference.
    84° ÷ 2 = 42°

    Angles in a triangle add up to 180°, base angles in an isosceles are equal.
    (180° - 42°) ÷ 2 = 69°

    Answer is 69°.


    Question 24(?).
    Table - 100, 25, 4 (?)


    Question 25.
    Attachment 538759

    (3-√6) ÷ 12
    You know question 14 - the one that was 100-25π - the question said leave your answer in its simplest form. I'm just wondering, were we supposed to put 25(4-π) ? Or is it "simpler" to put 100-25π ?
