Calculate the mean, the variance, and the standard deviation of the following discrete probability distribution. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round your final answers to 2 decimal places.) x −39 −19 −14 −6 P(X = x) 0.48 0.29 0.15 0.08

e) none of the above because the measure of angle cba is 101°

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

if x = 1, then the answer is 3.5

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
