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.

What’s the relationship among speed frequency and the number of poles in a three phase induction motor

Answers

Answer:

The number of poles in the windings defines the motor's ideal speed. A motor with a higher number of poles will have a slower rated speed but a higher rated torque.

Explanation:

The relationship among speed, frequency, and the number of poles in a three-phase induction motor is governed by what is known as the synchronous speed equation.

The synchronous speed of an induction motor is the speed at which the rotating magnetic field generated by the stator windings of the motor rotates.

The synchronous speed (Ns) of a three-phase induction motor is given by the following equation:

Ns = (120 × f) / P

where:

Ns is the synchronous speed in revolutions per minute (RPM).

f is the supply frequency in hertz (Hz).

P is the number of poles.

From the equation, it can be observed that the synchronous speed is directly proportional to the frequency and inversely proportional to the number of poles.

This means that if the frequency increases, the synchronous speed also increases, assuming the number of poles remains constant.

Conversely, if the frequency decreases, the synchronous speed decreases.

The actual speed of an induction motor is known as the rotor speed or slip speed, which is always slightly lower than the synchronous speed. The difference between the synchronous speed and the actual speed is referred to as slip and is necessary for the motor to induce a voltage in the rotor and generate torque.

It's important to note that the synchronous speed equation assumes an ideal motor with no load. In practice, the actual speed of the motor depends on various factors, including the load torque, rotor resistance, and motor design.

A data analyst is working with a data frame named retail. It has separate columns for dollars (price_dollars) and cents (price_cents). The analyst wants to combine the two columns into a single column named price, with the dollars and cents separated by a decimal point. For example, if the value in the price_dollars column is 10, and the value in the price_cents column is 50, the value in the price column will be 10.50. What code chunk lets the analyst create the price column

Answers

The code chunk that lets the analyst create the price column is;

unite(retail, “price”, price_dollars, price_cents, sep=”.”)

The code chunk unite(retail, “price”, price_dollars, price_cents, sep=”.”) is the one that will allow the analyst to create the price column.

The reason for that answer is that;

The unite() function would allow the analyst  to make the dollars and cents data to be combined into a single column.Meanwhile, in the parentheses of the given function, the analyst will write the name of the data frame.Next step for the analyst is to write the name of the new column in quotation marks.Next step is the names of the two columns they want to combine.Lastly, the argument sep=”.” will now place a decimal point between the dollars and cents data given in the price column.

The function mystery that takes as input a positive integer n is given below. The number of times that can n be halved (using integer division) before reaching 1 is infinite.

What are function mysteries?

The non-negative integers are used to define the mystery function. The more common name of this method is hidden to avoid tempting you to explore the Web for assistance in completing this task, which would be a very dishonorable thing to do. Assume n has m bits.

Count= 0

While n > 1

n = n

Count += 1

Return count

Once. You now have 1/2. You can split 1/2 in half to make quarters, but that is not dividing one, it is dividing one half. If you mean how long the series of subsequent subdivisions you can make can be, the answer is infinite.

Therefore, the number of times that can n be halved (using integer division) before reaching 1 is infinite.

4) Transference

Answers

When a company purchases a flood insurance policy for its data center, the risk management decision it took is: 4) Transference.

Risk management can be defined as a process which involves identifying, evaluating, analyzing and controlling potential risks (threats) that are present in a business, which can serve as an obstacle to its capital, revenues and profits.

Basically, risk management decision typically involves prioritizing cause of action or potential threats, so as to avoid, mitigate or transfer the risk that are likely to arise from such business decisions.

The risks or threats that are faced by a business firm can be transferred to a third-party such as an insurance agency, especially to protect its assets and resources in the event of a natural disaster such as flood, fire, earthquake, etc.

In conclusion, transference is a risk management decision that occurs when  a company purchases a flood insurance policy for its data center.
