The downtime per day for a computing facility has mean 4 hours and standard deviation .8 hour. Suppose that we want to compute probabilities about the average daily downtime for a period of 30 days.
i. What assumptions must be true to use the result of Theorem 7.4 to obtain a valid approximation for probabilities about the average daily downtime?
ii. Under the assumptions described in part (i), what is the approximate probability that the average daily downtime for a period of 30 days is between 1 and 5 hours?

Answers

Answer:

1

Step-by-step explanation:

Given :

Mean, μ = 4

Standard deviation, s = 0.8

Sample size, n = 30

The distribution is independent.

Z = (x - μ) / s /sqrt(n)

Probability that downtime period is between 1 and 5

P(1≤ x ≤ 5) :

[(x - μ) / (s /sqrt(n))] ≤ Z ≤ [(x - μ) / (s /sqrt(n))]

[(1 - 4) / (0.8 /sqrt(30))] ≤ Z ≤ [(5 - 4) / (0.8 /sqrt(30)]

[-3 / 0.1460593] ≤ Z ≤] 1 / 0.1460593]

P(-20.539602 ≤ Z ≤ 6.8465342)

P(Z ≤ 6.8465342) - P(Z ≤ - 20.5396)

P(Z ≤ 6.8465342) = 1 (Z probability calculator)

P(Z ≤ - 20.5396) = 0 (Z probability calculator)

1 - 0 = 1

Log 81 base 12

According to rule of logarithm :

Log 81 base 12 = (log 81 base 10) / log 12 base 10)

Obtaining the value :

(log 81 base 10) / log 12 base 10) = 1.7684564

Using trial and error method :

log 81 / In 12 = 0.7680308

write an equation in point slope form of the line that passes through the point (-8,-2) and had a slope of m=5

Answers

Answer:

5x - y + 38 = 0

Step-by-step explanation:

solution:

slope(m) = 5

(x1 , y1) = (-8 , -2)

we know that,

(y - y1) = m(x -x1)

or, (y - -2) = 5(x - -8)

or, y+2 = 5(x + 8)

or, y+2 = 5x +40

or, 5x - y + 38 = 0 is the required equation

The student council raised $2,790 during its annual fundraiser. The money was shared equally among the Events Committee, the Sports Committee, and the Sunshine Committee. a. The Sports Committee wants to use its share of the money to purchase t-shirts. If each t-shirt costs $12, what is the greatest number of t-shirts the Sports Committee can purchase? The greatest number of t-shirts that the Sports Committee can purchase is .

Answers

Answer:

The greatest number of t-shirts that the Sports Committee can purchase is 232.

Step-by-step explanation:

The student council raised $2,790 during its annual fundraiser.

Each t-shirt costs $12.

The total cost of buying x t-shirts is given by:

[tex]T(x) = 12x[/tex]

What is the greatest number of t-shirts the Sports Committee can purchase?

The total cost has to be lesser, or equal, to 2790. So

[tex]T(x) \leq 2790[/tex]

[tex]12x \leq 2790[/tex]

[tex]x \leq \frac{2790}{12}[/tex]

[tex]x \leq 232.5[/tex]

Since you cant buy half a shirt.

The greatest number of t-shirts that the Sports Committee can purchase is 232.

Answers

The shortest side is 16. Tip: add up all the sides to equal the perimeter.

pls help
I suck at this

Answers

Answer:

65

Step-by-step explanation:

We know that one angle is 50 degrees, so the angle supplementary to it will be 180-50, or 130 degrees.

Since these two lines are parallel, then the angle supplementary to 2x will be equal to 50 degrees, giving us 2x = 130 degrees, and x = 65 degrees.

A hardware store rents vacuum cleaners that customers may use for part or all of a day before returning. The store charges a flat fee plus an hourly rate. Write a linear function for the total rental cost, f(x), of a vacuum cleaner after x hours of rental. *

Answers

Answer:

f(x) = bx + y

Step-by-step explanation:

Linear functions are very easy as you simply need to multiply the cost per hour (in this scenario) by the total number of hours that the individual is renting the vacuum for. Then you simply add any indpendent value such as the flat fee that the hardware store charges. We can use these values to create the following function.

f(x) = bx + y

where:

b = hourly rate

x = hours of rental

y = flat fee

B. (8 + 3) • 4

C. 4 • (3 + 8)

D. 4 • 8 + 4 • 3

Answers

Step-by-step explanation:

We need to find an expression that is equivalent to 4×(8+3)

We know that,

4×(8+3) = 4(11) = 44

Option (1).

(4 • 8) + 3 = 32+3 = 35. It is incorrect

Option (2).

(8 + 3) • 4 = (11) 4 = 44. It is correct.

Option (3).

4 • (3 + 8) = 4(11) = 44. It is correct.

Option (4).

4 • 8 + 4 • 3 = 32+12 = 44. It is correct.

Hence, the correct options are (2), (3) and (4).

Now, therefore, by virtue of the authority vested in me as President of the United States, and Commander in Chief of the Army and Navy, I hereby authorize and direct the Secretary of War, and the Military Commanders whom he may from time to time designate, whenever he or any designated Commander deems such action necessary or desirable, to prescribe military areas in such places and of such extent as he or the appropriate Military Commander may determine, from which any or all persons may be excluded, and with respect to which, the right of any person to enter, remain in, or leave shall be subject to whatever restrictions the Secretary of War or the appropriate Military Commander may impose in his discretion. The Secretary of War is hereby authorized to provide for residents of any such area who are excluded therefrom, such transportation, food, shelter, and other accommodations as may be necessary, in the judgment of the Secretary of War or the said Military Commander, and until other arrangements are made, to accomplish the purpose of this order. The designation of military areas in any region or locality shall supersede designations of prohibited and restricted areas by the Attorney General under the Proclamations of December 7 and 8, 1941, and shall supersede the responsibility and authority of the Attorney General under the said Proclamations in respect of such prohibited and restricted areas.
