Aconstruction project has four separate components that must be completed in order. the expected values and standard deviations of the completion times of the activities are listed below. assuming that the four activities are independent, determine the expected value and standard deviation of the completion time of the project

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

one set of data has more variation than the other. hope this !

i think the answer is b
