D 4 Yes 1.0
E 5 Yes 1.0
F 8 4.0
G 6 Yes 1.25
H 2 0.0

Required:
a. Specify the Project Completion Time and the Standard Deviation.
b. Calculate the z value.
c. What is the probability of completing the project in 23 weeks or less

it has the same slope and a different y-intercept

hope this : )

b.my answer is b.

brainliest

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
