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:
new technology.
Explanation:
An information system or technology can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems and technology in order to perform their duties, functions or tasks and to manage their operations effectively.

Additionally, an information system or technology comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
Overtime, millions of software programs have been created and have helped to improve the economy. This is an example of new technology.
Basically, these new technologies have helped to simplify the process of producing goods and services effectively and efficiently to meet the unending needs and requirements of the consumers.
