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
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.

Explain why you do not need expensive equipment to take pictures or record video?
Explanation:
Expensive equipment is not necessary because from a technical perspective as long as the device has a lens and a mic it should be able to take photos and videos.
Answer: No, you don't not need an expensive camera . It may have better quality or worst quality . A phone car record and take pictures. Using a Light Stand Can give you a better lighting and better angle so you don't have to hold it or put it on your table, lap, or desk.
Explanation: A lot of people think you need to own a good camera to take a good photograph. A more expensive camera can help, but certainly is not essential. To answer the question though, it is 'no' – the equipment really doesn't make any difference to the end result, but does affect the process of getting there.
