    Not a large enough sample size; 10? students does not represent a general populous.

    yass i got that !!!
    Coordinates were (1, 2.5), (5, 7)

    How can the midpoint be totally negative if the two points were positive(on the upper part of the graph??
    Surely the midpoint would be somewhere near the coordinates right?
    I put the midpoint was ( 3, 4.75)

    This is very hard to visualise from words, any rough drawing for me to go off of?

    I'm pretty sure it is 0.76.
    It asked for the probability of it not raining and the match not being cancelled.
    I got 7.6/100

    Small triangle = 1/2 * root3/3 * root2/2 = root6 /12

    Big triangle = 1/2 * root2/2 * root2/2 = 2/8 = 1/4

    Shaded region = Big - Small

    = 1/4 - root6/12

    = 3/12 - root6/12

    = (3-root6)/12

    what was the envelope question again and what was the answer
    Small packs (x) have 5 envelopes
    Large packs (y) have 20 envelopes
    Give a formula for total (T) number of envelopes

    T=5x+20y

    It didn't ask for the midpoint. (1, 2.5) was the midpoint.
