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
[tex]0.5x = 4[/tex]
[tex]x = \frac{4}{0.5}[/tex]
[tex]x = 8[/tex]
8 loads can be expected to occur during a 4-year period
