There are 37 jelly beans so p for the first one is 27/37. That leaves 36 in the bag. So p for the second jelly bean is 10/36=5/18.
The combine probability is 27/37×5/18=3/37×5/2=15/74.
The formula is,
(y [the second one] - y[the first one]) / (x [the second one] - x [the first one])
The first x=5, first y=12, second x=30, second y=72
Plug the numbers in, to get
(72-12) / (30-5)
Now just crunch it out.
(60) / (25)
=2.4
This is your answer.
Hope it helped!
first we change the format: y=-3x-5 Since its perpendicular the slope will be a negative inverse. y=mx+b
The width is 2, because area you need to times the length with width.
