Dean Smith is dissatisfied with the time it takes to get a new faculty ID made and believes more servers will speed up service and reduce costs thanks to shorter lines. Prof. Karen is tasked to study the situation. Prof. Karen observes an average of 20 customers/hr arriving and each technician (service window) serves 5 customer/hr, on average. Assume an M/M/s queue system. Prof. Karen calculates the operational cost of each server as $20/hr, and assumes a cost of waiting in the SYSTEM as $25/hr per customer. What is the optimal number of service windows to minimize total cost

Answers

Answer 1
The answer is :

X = 4

Explanation:
Answer 2

The optimal number of service windows to minimize total cost will be 5 service windows.

How to calculate the optimal value?

The optimal number of service windows to minimize total cost will be calculated thus:

Cost = 20x + 25(20 - 5x)

Cost = 20x + 500 - 125x

Cost = 500 - 105x

For the minimum cost,

500 - 105x = 0

105x = 500

x = 500/105

x = 4.76 = 5

Therefore, the optimal number of service windows to minimize total cost will be 5 service windows.

Which of the four factors of production are hit the hardest when high unemployment occurs ?


A. Land

B. Labor

C. Capitol

D. Management

Answers

Answer:

Land

Explanation:

people start to farm so that they earn money by selling those vegetables

Unemployment may result in increased payments from the state and federal governments for things like food stamps because unemployed persons tend to spend less and may accumulate more debt. Thus, option A is correct.

What hardest when high unemployment occurs?

High unemployment causes a decline in inflation. Voters and policymakers do not like dropping prices; they seek low unemployment and low inflation. They typically have to choose between the two and cannot usually have both.

Unemployed workers go through financial difficulties, which has an impact on their families, interpersonal relationships, and communities. If neglected, this can lead to a recession or even a depression as consumer spending, one of an economy's key sources of growth, falls.

Therefore, Land production is hit the hardest when high unemployment occurs.

Square the difference between the y values.3. Add the two squares.4. Take the square root of the result.In order to compute the square root of something, you need to use the sqrt function. This function belongs to a module in Python called math. The first line of the code provided imports this module, so that you can use the functions in it. To take the square root of a number, simply do something like the following:number = ...result = math.sqrt(number)You can also use the built-in Python function pow to take the square of a number, like this:number = ...square = pow(number, 2)

This code calculates the distance between points (1, 2) and (4, 6) using the Pythagorean Theorem, which yields a result of 5.0.

A Python function that calculates the distance between two coordinate pairs using the Pythagorean Theorem:

```python

import math

def distance(point1, point2):

   # Unpack the coordinate pairs into variables

   x1, y1 = point1

   x2, y2 = point2

   # Calculate the squared differences between x and y coordinates

   x_diff_sq = pow(x2 - x1, 2)

   y_diff_sq = pow(y2 - y1, 2)

   # Add the squared differences and take the square root of the result

   distance = math.sqrt(x_diff_sq + y_diff_sq)

   return distance

```

You can use this function by passing two tuples representing the coordinate pairs as arguments. For example:

```python

result = distance((1, 2), (4, 6))

print(result)  # Output: 5.0

```

This code calculates the distance between points (1, 2) and (4, 6) using the Pythagorean Theorem, which yields a result of 5.0.
