To write: The ratio of 18 to 20 in simplest form on using the fractional notation.

Answer to Problem 1IR
The simplest form of the ratio 18 to 20 is
Explanation of Solution
Procedure used:
Writing ratio as a fraction:
“To write a ratio as a fraction, write the first number of the ratio as the numerator of the fraction and the second number as a denominator. The order of the quantities is important here.”
Calculation:
The given ratio is 18 to 20.
The first number of the ratio is 18 and the second number is 20.
Write the first number as numerator and second number as denominator for fractional notation.
Then, the ratio 18 to 20 can be written as
Simplify the fraction
Thus, the simplest form of the ratio 18 to 20 is

Thank you.arrow_forwardIn a small office, there are m = 5 typists who need to use a single typewriter to complete their reports. Assume the time each typist takes to prepare a report follows an exponential distribution with an average of 20 minutes per preparation (A = 3 reports/hour), and the service time for the typewriter to type out a report also follows an exponential distribution, averaging 30 minutes to complete a report (μ 2 reports/hour). Given that the number of typists is finite and all typists = share one typewriter, they will form a waiting queue. (1). Describe this queuing system and explain how it fits the characteristics of the M/M/1/∞0/m model. (2). Calculate the probability that any typist is using the typewriter at steady-state. (3). Calculate the average number of typists waiting in the queue at steady-state. (4). Considering the need to reduce waiting time, if an additional typewriter is introduced (turning into a two-server system, or M/M/2/∞0/m model), analyze the expected impact,…arrow_forward
