Answer:
(a) 75% (b) 25% (c) 2.25 customers (d) 12 minutes (e) 0.25 (f)0.237
Explanation:
Solution
Given that:
The Arrival rate at Poisson distribution = 15 per hour = λ
The Service rate at exponential distribution = 20 per hour = μ
(a) System utilization = λ/μ = 15 / 20 = 0.75 = 75%
(b) The Probability of zero requests in server = 1 - λ/μ = 1 - 0.75 = 0.25
or
The percentage of time server will be idle = 25%
(c)The expected number of customers waiting to be served = Average number of customers in line = λ^2/μ (μ-λ ) = 225 /20(20-15) = 45 /20 = 2.25
Therefore, it is expected that on an average, 2.25 customers are waiting in line to get served.
(d)The average time customers will spend in system = 1/(μ-λ )
=1/(20 - 15) = 1/5 hours = 12 minutes
(e)The probability of zero customer in system = 1 -λ/μ = 1 - 0.75 = 0.25
(f) The probability of more than 4 customers in the system = (λ/μ)^ 4+1
= (15/20)5 = 0.237

Explanation:
Based on their observations of what actually occurs in the organization, employees demonstrate the enacted values and norms.
Your values are the things you hold dear in terms of how you conduct your life and career. Value indicates the significance of an action or thing in ethics and social sciences. Values include things like money, allegiance, independence, fairness, equality, justice, brotherhood, and friendship. Values include things like money, allegiance, independence, fairness, equality, justice, brotherhood, and friendship. In the social sciences, norms are a key notion. Norms are most frequently described as socially imposed laws or expectations. Norms can be prescriptive (encouraging good behavior, such as "be honest") or proscriptive (forbidding bad behavior, such as "do not cheat").
