Answer:
server utilization = 0.75
Explanation:
given data
single phase automatic teller = 7.5 minutes
average rate = 1 every 10 minutes
solution
we get here Service rate that is
Service rate [tex]\mu[/tex] = [tex]\frac{7.5}{60}[/tex]
Service rate [tex]\mu[/tex] = 8 per hour
and here arrival rate will be
arrival rate [tex]\lambda[/tex] = [tex]\frac{10}{60}[/tex]
so here we get server utilization that is express as
server utilization = [tex]\frac{\lambda }{\mu}[/tex]
server utilization = [tex]\frac{6}{8}[/tex]
server utilization = 0.75
