Answer:
8 loads can be expected to occur during a 4-year period
Step-by-step explanation:
This question can be solved by a simple rule of three.
Suppose the mean time between occurrences of loads is 0.5 year.
This means that for 0.5 years, 1 occurence is expected.
(a) How many loads can be expected to occur during a 4-year period
0.5 years - 1 occurence
4 years - x occurrences



8 loads can be expected to occur during a 4-year period
X = 78, because
1) The last angle (the one without the X, equals 24 degrees)
2) 180 - 24 = 156
3) 156/2 = x
x = 78
