Customers arrive at a single self-serve coffee machine in a busy mall at the rate of 30 per hour, following Poisson distribution. Each customer takes exactly 72 seconds to get his or her coffee. What is the expected number of customers in line at this coffee machine

Step-by-step explanation:

The waiting line model explains that the utilization of the coffee machine or number of customers at any time is given as

ρ = (λ/μ)

λ = number of customers per hour = 30 customers per hour

μ = rate at which customers use the machine = (1 customer)/(72 seconds)

= [1 ÷ (72/3600)] customer per hour

= 1 ÷

Hope this Helps!!!

step-by-step explanation:

you can not divide by 0 so 4 ÷ 0 would be 0

0 × 9999 =0

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
