IrinaK [193]

Answer:

3 customers

Step-by-step explanation:

Rate of arrival (λ) = 15 per hour

Service rate (μ) = 20 per hour

The number of customers in a system given the arrival rate and the mean service rate is given by:

N = \frac{\lambda}{\mu-\lambda}\\

Applying the given data:

N = \frac{15}{20-5}\\N=3\ customers

The average number of customers in the system is 3 customers.
