The slope of the line of best fit in the scatterplot below can be determined using the formula for the slope of a line:
Slope = (y2-y1)/(x2-x1)

In this case, x1 = 3, y1 = 12, x2 = 6, y2 = 19. So, the slope of the line of best fit is (19 - 12) / (6 - 3), which equals 7/3 or 2.33.
The line of best fit is the line that best represents the data on a scatterplot. It is the line that is closest to all the data points in the graph. The slope of the line of best fit helps to indicate whether the data points are moving in a positive or negative direction. If the slope is positive, the data points are increasing, and if the slope is negative, the data points are decreasing.
A positive slope, like the one in this example, means that as x increases, y also increases. This means that in this case, as the x-values (3 and 6) increase, the y-values (12 and 19) also increase.

The slope of the line of best fit can also be used to make predictions about values of y, given values of x. For example, if x = 8, then y = 26, because the slope of the line of best fit is 2.33, and 8*2.33 = 19.8, which is approximately equal to 26.
Overall, the slope of the line of best fit on this scatterplot is 2.33, which is a positive number. This indicates that as the x-values increase, the y-values also increase, and it can also be used to make predictions about y-values, given x-values.

1. The server utilization is 500%.

2. The average response time in the system cannot be accurately calculated due to an overloaded and unstable system.

3. The average waiting time in the queue cannot be accurately calculated due to an overloaded and unstable system.

Q1. How do we calculate server utilization?

The server utilization can be calculated by dividing the request processing rate by the request arrival rate. In this case, the server utilization would be:

Server Utilization = Request Processing Rate / Request Arrival Rate

= 20 req/s / 4 req/s

= 5/1

= 5

Therefore, the server utilization is 5 or 500% (since it exceeds 100%).

Q2. How do we calculate average response time?

To calculate the average response time in the system, we need to consider the queuing delay (waiting time in the queue) and the service time (time taken to process a request). In the M/M/1 queue model, the average response time is the sum of the average queuing delay and the average service time.

Average Service Time = 1 / Request Processing Rate

= 1 / 20 req/s

= 0.05 s

The M/M/1 queue model has a known formula for the average queuing delay, which is:

Average Queuing Delay = (Server Utilization²) / (1 - Server Utilization) * Average Service Time

= (5²) / (1 - 5) * 0.05 s

= 25 / -4 * 0.05 s

= -1.25 s

Since the queuing delay cannot be negative, it suggests that the server is overloaded, and the system is unstable. In this case, the average response time cannot be calculated accurately using the M/M/1 model.

Q3. How do we calculate average waiting time?

Similarly, to calculate the average waiting time in the queue, we can use the formula for the average queuing delay mentioned above:

Average Waiting Time = (Server Utilization²) / (1 - Server Utilization) * Average Service Time

= (5²) / (1 - 5) * 0.05 s

= -1.25 s

Again, due to the negative value, it suggests an overloaded and unstable system, so the average waiting time cannot be accurately calculated using the M/M/1 model.

the return on equity (after tax) ratio for 2017 is 3.47% and for 2018 is 5.61%.To calculate the return on equity (ROE) ratio, we need to determine the net income and average stockholders' equity for both 2017 and 2018.

Net Income:
2017: $1,338
2018: $2,160

Average Stockholders' Equity:
2017: ($31,500 + $45,500) / 2 = $38,500
2018: ($31,500 + $45,500) / 2 = $38,500

ROE Ratio:
2017: $1,338 / $38,500 = 0.0347 or 3.47%
2018: $2,160 / $38,500 = 0.0561 or 5.61%

An initial amount of $725,000, an APR of 6.25%, and a desired time frame of 22 years, the monthly withdrawal amount would be approximately $4,491.95.

To calculate the monthly withdrawal amount that would completely exhaust your savings in 22 years, we can use the present value of an ordinary annuity formula. The present value (PV) represents the initial amount you have, the interest rate per period (i) is the monthly interest rate, and the number of periods (n) is the total number of months.

Here's the step-by-step calculation:

Convert the APR to a monthly interest rate:

Monthly interest rate (i) = Annual interest rate / Number of compounding periods per year

i = 6.25% / 12 = 0.0625 / 12 = 0.00521 (rounded to 5 decimal places)

Determine the total number of periods:

Total number of periods (n) = Number of years * Number of compounding periods per year

n = 22 * 12 = 264

Use the present value of an ordinary annuity formula to calculate the monthly withdrawal amount (PMT):

PMT = PV / [(1 - (1 + i)^(-n)) / i]

In this case, PV = $725,000

PMT = $725,000 / [(1 - (1 + 0.00521)^(-264)) / 0.00521]

Calculate the monthly withdrawal amount using a financial calculator or spreadsheet software:

PMT ≈ $4,491.95 (rounded to the nearest cent)

Therefore, you can withdraw approximately $4,491.95 per month to completely exhaust your savings in 22 years assuming monthly compounding.

Any non-empty subset of Rⁿ, where any linear combination of vectors in S is again a vector in S, is a subspace of Rⁿ.

Given that S is a non-empty subset of Rⁿ such that any linear combination of vectors in S is again a vector in S. Therefore, to prove that S is a subspace of Rⁿ, we have to show that S satisfies three conditions. These conditions are as follows;

The condition for being a subspace of Rⁿ

Firstly, a subspace must be closed under addition. In other words, if x and y are any two vectors in S, then their sum x + y must be in S.

Secondly, a subspace must be closed under scalar multiplication. In other words, if x is any vector in S and c is any scalar, then cx must be in S.

Finally, a subspace must contain the zero vector, denoted by 0.S is a subspace of Rⁿ

From the conditions mentioned above, we can show that S is indeed a subspace of Rⁿ, since S satisfies all the required conditions.

Therefore, we can say that any non-empty subset of Rⁿ, where any linear combination of vectors in S is again a vector in S, is a subspace of Rⁿ.
