B and C 

the answers I input in B are wrong 

Suppose x is a random variable best described by a uniform probability distribution withc=10 and d = 25.
a. Find f(x).
b. Find the mean and standard deviation of x.
c. Graph f(x) and locate u and the intervalµ±20 on the graph. Note that the probability that x assumes a value within the interval u ± 20 is equal to 1.
a. Find f(x). Choose the correct answer below.
A. f(x)=
15
(10<x< 25)
O B. f(x) =
(10sx)
15
1
O C. f(x) = 0 (0sx<25)
10
D. f(x) =
(25 <x)
10
b. Find the mean and standard deviation of x.
H= 10.7!
O =4.330
(Round to three decimal places as needed.)
