If you are trying to find where he is the answer is -29.7
Hope this helps!
a) 
because it is equal to the area of the shaded region between X=4 and X=6, and the probability that X falls within some interval is given by the area under the PDF.
b) 
because the shaded region is a rectangle of height 1/5 (by virtue of X following a uniform distribution over the interval [2, 7], which has length 5).
The answer is A,
if you plug in the points of (2,-5) into
y=x-7
-5=2-7
-5=-5
so the equation is true
First you get both distances
9.3 x 107 = 995.1 miles
8.87 x 108 = 957.96 miles
then you subtract them both
995.1 - 957.96 = 37.14 miles
and 37.14 miles is the distance between Earth and Saturn.
Five hundred ninety two thousand six hundred eighty two
