Equation for the work:
The equation for the work done is given by:

In which F is the force needed and d is the distance. The time does not interfere on the work.
A 300-lb gorilla climbs a tree to a height of 30 ft
This means that 
Thus

The work done in both cases is of 9000 ft-lb, as the work is not a function of time.

Answer:
the probability having no customers are in the system is 0.375
Step-by-step explanation:
The computation of the probability having no customers are in the system is as follows;
Given that the arrival rate is 1.25 customers per minute
The Service rate is 2 customers per minute
Based on the above information, the probability is

Hence, the probability having no customers are in the system is 0.375
149 will be rounded to 150 so 150×5= 750
