i think i did 9 wrong
i did 4x + 9 = 111
instead of 4x - 9 = 111
the width of the garden is 4.5m shorter than the length
yeah ****
whoops

answer to 5b was 3.22+2(0.84) = 4.9
5c was normalcdf = 32.35% or 32.4%.

cant remember what the 5d question was, but im pretty sure that wasnt it.

7c was school 2 as it was 25% that had below 10cm, the median for school 1 was 10cm which was above 25%.
