Consider the trapezoid D with corners (0, 0), (1, 0), (1, 1) and (0, 2). We choose a point (X, Y ) uniformly at random from D. (a) Find the cumulative distribution function of FX of X and FY of Y .

The solution is given in the attachments

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is 1030 it's very simple math.
