Answer:
X = -4
Step-by-step explanation:
Negative 4, 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).
This will leave you with
140 = 2(40) + 2x
60 = 2x
30= x
So the length is 30.
