Respuesta :

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
