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.<br>a. Find f(x).<br>b. Find the mean and standard deviation of x.<br>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.<br>a. Find f(x). Choose the correct answer below.<br>A. f(x)=<br>15<br>(10<x< 25)<br>O B. f(x) =<br>(10sx)<br>15<br>1<br>O C. f(x) = 0 (0sx<25)<br>10<br>D. f(x) =<br>(25 <x)<br>10<br>b. Find the mean and standard deviation of x.<br>H= 10.7!<br>O =4.330<br>(Round to three decimal places as needed.)<br>
