A single-server waiting line system has an arrival pattern characterized by a Poisson distribution with 3 customers per hour. Th

Answer:

18 minutes

Step-by-step explanation:

Given that:

The arrival time = 3 customers / hour

The avg. service rate (s) = 12 minutes per customer

To hour, we have:

$s = \dfrac{60}{12}$

s = 5 customers/ hour

Thus, the required average time for a customer needs to wait in line is:

$= \dfrac{3}{5}\times (5-3) hours \\ \\ = \dfrac{3}{5}\times 2 \\ \\ = \dfrac{3}{10} \ hours$

To minutes;

$= 3 \times \dfrac{60}{10} \ minutes$

= 18 minutes

A rectangular prism has a length of 2 1/2 meters, a width of 4 meters, and a height of 2 1/4 meters.

First we need to convert our fractions into decimals, it's just a lot easier to work with.
2 1/2 is equal to 2.5
2 1/4 is equal to 2.25
Then we plug our numbers into the formula used to find the volume of a rectangle:
V=L*W*H
Volume equals Length times Width times Height.
V=2.5*4*2.25
V=22.5
22.5 is already in decimal form, or if you'd rather have a mixed number, your answer is 22 $\frac{1}{2}$
