American Vending supplies vended food to a large university. Because students often kick the machines out of anger and frustration, management has a constant repair problem. The machines break down in a mean of 3 hours with a standard deviation of 3 hours. One repair worker can service one machine in a mean of 2 hours with a standard deviation of 2 hours. Currently, TWO repair workers are hired. Average flow time (W) was calculated as 2.305 from the posted queueing template. --- Average down machines in the entire system (L) are ___.

Answers

Answer 1

Answer:

0.77

Step-by-step explanation:

From the information given:

The breakdown time (a)= 3 hours

The breakdown rate (λ) = 1/a = 1/3

Average flow time in the system (W) = 2.305 hours

For the entire system;

The average down machines L = Wλ

= 2.305 × (1/3)

= 0.77

Answer:

7/22

Step-by-step explanation:

From the question given above, the following data were:

Drama n(D) = 25

Sport n(S) = 140

Both drama and sport n(DnS) = 60

Not in drama or sport n(DnS)ᶜ = 105

Total or sample space n(S) = 330

Probability of not in drama or sport P(DnS)ᶜ =?

The probability that the student chosen is not in drama or sport can be obtained as follow:

P(DnS)ᶜ = n(DnS)ᶜ / nS

P(DnS)ᶜ = 105 / 330

Express the above to its lowest terms

P(DnS)ᶜ = 7/22

Therefore, the probability that the student chosen is not in drama or sport is 7/22

Divide the percent by 100, write it as a fraction, and simplify.
Multiply the percent by 100, write it as a fraction, and simplify.

Answers

Answer:

Write a fraction using the percent over 100 and simplify. AND. Divide the percent by 100, write it as a fraction, and simplify.

Step-by-step explanation:

Let's test all the answers and see which statements are true.

Let's just use 50 as the percent to test it. These statements should end up looking like [tex]\frac{1}{2}[/tex]

Write a fraction using the percent over 10 and simplify.

[tex]\frac{50}{10} =5[/tex], half of ten is 5, so this makes it invalid.

Write a fraction using the percent over 100 and simplify.

[tex]\frac{50}{100} =\frac{1}{2}[/tex], this is valid.

Divide the percent by 100, write it as a fraction, and simplify.

[tex]\frac{50}{100} =\frac{1}{2}[/tex], valid!

Multiply the percent by 100, write it as a fraction, and simplify.

[tex]50*100=500[/tex], invalid.

The two valid statements are: Write a fraction using the percent over 100 and simplify. AND. Divide the percent by 100, write it as a fraction, and simplify.

increasing on 0 < x < 2f(2) = 4decreasing on 2 < x < 5

Step-by-step explanation:

You need to know that an even function is symmetrical about the y-axis. The graph to the right of the y-axis is the mirror image of the graph to the left. With that in mind, the questions are easily answered.

It might help to draw the function graph, as we did in the attached. Then it is more straightforward to see what is happening in each of the intervals.

The function is increasing in the interval 0 < x < 2.

The function value at x=2 is 4: f(2) = 4.

The function is decreasing in the interval 2 < x < 5.

Help!! Pythagorean theorem

Answers

Answer:

The Pythagorean theorem only works for right triangles. This is not a right triangle.

x = 23

All interior angles of a triangle = 180 degrees.

 A  +      B      +     C    + 180

(3x) + (2x+12) + (2x+7) = 180

7x + 19 = 180

7x = 161

x = 23

A = 3(23) = 69 degrees
