You could break down the shape and then get to the area but there is a better way.
The picture looks like a rectangle with a chunk pulled off it.
Let just imagine that it was a perfect rectangle.
Its dimensions would be 57 by 36 (20+16).
Perfect Rectangle Area = 57x36 = 2052
Now, let us find the area of the indent and subtract that from the previous area.
Indent Area = 16 x (57-15-15) = 16x27 = 432
Real Area = 2052 - 432
= 1620
answer = 1620
Answer:
Well this is a bit of a tall order :) but here we go:
A. See the attached frequency tables, done vertically and horizontally.
B. We can see from the horizontal freq table that .6 = 60% of all the pine trees died.
C. The probability that a tree survived given it was a pine is .6 = 60%. The probability that a tree survived given it was an oak is .75 = 75%. According to this sample, the oaks were more likely survive than the pines.
