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

Answer:
improvements to the building,
Explanation:
Opportunity cost is the foregone advantage of not setting certain options in decision making. When a particular option is preferred over others, then benefit from the other options not selected are forfeited. The forfeited benefits represent the opportunity cost.
The value of opportunity cost is equated to the value of the next best alternative. Where there were more than two alternatives available, the next best alternative from the chosen option becomes the opportunity cost. In this case, improvement to the building was voted the second preferred option; hence it becomes the opportunity cost.

Option b.
Explanation:
In standard cycle, competitive actions are designed to serve large market shares, to gain customer loyalty and to control the firm's operations which in turn provide the same positive experience to customers.
Goods or services in standard-cycle markets reflect <u>organizations that serve a mass market.</u>
Standard-cycle markets refer to the markets where the firm's competitive advantages are shielded from imitation such that those advantages can be sustained longer but for a shorter period.
These advantages can be sustained for longer period in a slow-cycle market than in fast-cycle markets.
Competitive advantages are sustainable in slow-cycle as these are shielded from imitation for longer periods of time such that imitation is costly.
Option b. is correct
