Answer:
The standard deviation on the critical path = 0.834
Step-by-step explanation:
Variance of activity A (
) = 0.33
Variance of activity B (
) = 0.67
Variance of activity C (
) = 0.33
Variance of activity D (
) = 0.17
Thus the standard deviation on the critical path (
) =

Answer:
Option b. sum of all areas of faces
Step-by-step explanation:
we know that
The surface area of the prism is equal to the area of its bases plus the area of its four rectangular lateral faces
so

where
B is the area of the base
P is the perimeter of the base
H is the height of the prism
therefore
sum of all areas of faces
