Suppose the random variable X has the uniform distirbution on [a, b]. Find expressions involving a and b for the expected valkue, variance, and standard deviation, of X. Check that your expressions when a=0 and b=10 addree with what you go in park c of part c of problem 5.

Mean = 5

Variance = 8.3521

Standard Deviation = 2.89

Step-by-step explanation:

X has the uniform distribution on [a, b]

[a, b] = [a, 10]

Mean is solved using (a + b)/2

Standard Deviation =

Standard Deviation =

Variance =

Variance =

4.

step-by-step explanation:

it have the same area.brainliest

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
