Probability of orders arriving on time is .95. suppose the retailer randomly selects 110 orders. let x=the number of orders that arrive on time. calculate and interpret the mean and standard deviation of x.

3x^3-x^2+6x-9

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
