the queue model follows m/m/1 with request arrival rate = 4 req/s and request processing rate = 20 req/sQ1. What is the server utilization? Q2. What is the average response time in the system? Q3. What is the average waiting time in the queue?

Answers

Answer 1

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.

factor 11k^4 − 88k^3 + 77k^2

Answers

Answer:

11k^2 (k - 7)(k - 1)

Step-by-step explanation:

The highest common factor is

11k^2

Using the distributive property we get at least 2 factors.

11k^2 ( k^2 - 8k + 7)

The second factor reduces yet again.

11k^2 (k - 7)(k - 1)

Answer:

11k^2(k−7)(k−1)

Step-by-step explanation:

11k^4 − 88k^3 + 77k^2

Factor out 11.

11(k^4-8k^3+7k^2)

Consider k^4-8k^3+7k^2. Factor out k^2.

k^2(k^2−8k+7)

Consider k^2 −8k+7. Factor the expression by grouping. First, the expression needs to be rewritten as k^2+ak+bk+7. To find a and b, set up a system to be solved.

a+b=−8

ab=1×7=7

Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. The only such pair is the system solution.

a=−7

b=−1

Rewrite k^2−8k+7 as (k^2−7k)+(−k+7).

(k^2−7k)+(−k+7)

Factor out k in the first and −1 in the second group.

k(k−7)−(k−7)

Factor out common term k−7 by using distributive property.

(k−7)(k−1)

Rewrite the complete factored expression.

11k^2(k−7)(k−1)

Step-by-step explanation:

In order to simplify we do the following...

[tex]5y + \frac{5}{14} + 9n + \frac{2}{14} + 2y - 3n = (5y +2y) +(\frac{5}{14}+ \frac{2}{14}) + (9n - 3n) = 7y + \frac{1}{2} + 6n[/tex]

Answer:

This expression can be simplified to 7y + 6n + 1/2

Step-by-step explanation:

You can find this by grouping like terms and adding them together.  Starting with the expression we're given:

5y + 5/14 + 9n + 2/14 + 2y - 3n

Let's make it easier by grouping like terms:

(5y + 2y) + (9n - 3n) + (5/14 + 2/14)

Now we'll add them together:

7y + 6n + 7/14

And finally, we can simplify that fraction by factoring 7 out of both the numerator and denominator:

7y + 6n + 1/2

And now we have the final answer.

On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 4, negative 4) and goes up to an open circle at (negative 1, 2).

Answers

Step-by-step explanation/Answer:

The value for h(3) is 1.

Coordinate (3,1)

The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.

So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:

Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.

Answers

Answer:

Number of different ways can she spend her Saturday = 54

Step-by-step explanation:

Jane has to do three types of things - Work out , Eat and Read a book

In Work out -

She either lift weights, run, or hike

In Eating -

She will choose 1 of the 6 restaurants near her home

In Reading -

Read either Harry Potter, Catcher in the Rye, or Girl on the Train

Number of ways in which she can work put = ³C₁ = [tex]\frac{3!}{1! (3-1)!} = \frac{3!}{2!} = 3[/tex]

Number of ways in which she can eat = ⁶C₁ =  [tex]\frac{6!}{1! (6-1)!} = \frac{6!}{5!} = 6[/tex]

Number of ways in which she can read =  ³C₁ = [tex]\frac{3!}{1! (3-1)!} = \frac{3!}{2!} = 3[/tex]

So, Total number of ways = 3×6×3 = 54

You can draw the eagle and mouse by using a right triangle. You know that the height of the triangle will be 280 feet and the distance between eagle and mouse should be the hypotenuse. Since we know the angle and one side of the triangle, we can use trignometry (cosine(angle)=adjacent/hypotenuse). Plug in your values and solve for the hypotenuse.

if your graph the equation you will clearly see that it is declining and if you don't know how to graph the equation then go to the demos calculator, its an app & website, super easy to use. most people would assume the answer would be one of the 88.5% just because it's in the original equation but the .885 in the equation doesn't represent the rate of change there for the answer is 11.5%.
