The distribution is not Normal: many house- holds pay a low rate as part of a bundle with phone or television service, but some pay much more for Inter- net only or for faster connections.
A sample survey asks an SRS of 50 households with Internet access how much they pay. Let x be the mean amount paid.
(a) Explain why you can't determine the probability that the amount a randomly selected household pays for access to the Internet exceeds $55.
(b) What are the mean and standard deviation of the sampling distribution of ?
(c) What is the shape of the sampling distribution of x? Justify your answer.
(d) Find the probability that the average fee paid by the sample of households exceeds $55. television service, but some pay much more for Inter- net only or for faster connections.

Answers

Answer:

(a) See Explanation

(b) [tex]\bar x =50[/tex] and [tex]\sigma_x = 0.8944[/tex]

(c) The shape is normal

(d) [tex]P(\bar x > 55) = 0[/tex]

Step-by-step explanation:

Given

[tex]\mu = \$50[/tex] -- mean

[tex]\sigma = \$20[/tex] --- standard deviation

[tex]n=500[/tex] --- sample size

Solving (a): The reason we can't determine the probability that an amount to access internet by a household will exceed $55.

The question says that a lot of households pay low rates, but the percentage of the households in this category is not given. This means that it is impossible to determine the shape of the distribution.

Hence, the probability cannot be calculated.

Solving (b): Sample mean and Sample standard deviation

The sample mean estimates the population mean

So:

[tex]\bar x =\mu[/tex]

[tex]\bar x =50[/tex]

The sample standard deviation is calculated as thus:

[tex]\sigma_x = \frac{\sigma}{\sqrt n}[/tex]

[tex]\sigma_x = \frac{20}{\sqrt{500}}[/tex]

[tex]\sigma_x = \frac{20}{22.36}[/tex]

[tex]\sigma_x = 0.8944[/tex]

Solving (c): The shape of the distribution.

We have:

[tex]n = 500[/tex] --- The sample size

According to Central limit theorem, When the sample size is greater than 30, then the shape of the distribution is normal.

Hence, the shape is normal

Solving (d): [tex]P(\bar x \ge 55)[/tex]

Calculate the test statistic (t)

[tex]t = \frac{\bar x - \mu}{\sigma}[/tex]

[tex]t = \frac{55 - 50}{0.8945}[/tex]

[tex]t = \frac{5}{0.8945}[/tex]

[tex]t = 5.590[/tex]

So:

[tex]P(\bar x > 55) = P(t > 5.590)[/tex]

Referencing the z table, we have:

[tex]P(t > 5.590) = 0[/tex]

Hence:

[tex]P(\bar x > 55) = 0[/tex]

Answers

Answer:

=1

Step-by-step explanation:

log3(x+2)-log3(x)=1

Subtraction sign means you can divide the values inside the parintheses

log3(x+2/x)=1

split up the fraction into x/x and 2/x; x/x = 1

log3(1+(2/x))=1

Change of base - three to the first power = value in parintheses

3to1st=1+(2/x)

subtract 1 from both sides

2=2/x

divide both sides by 2

x=1

What effect does this have on the surface area of the pyramid? A. The surface area of the pyramid is multiplied by 10. B. The surface area of the pyramid is multiplied by 50. C. The surface area of the pyramid is multiplied by 100. D. The surface area of the pyramid is multiplied by 1,000. E. The effect on the surface area cannot be determined.

Answers

Answer:

C. The surface area of the pyramid is multiplied by 100

Step-by-step explanation:

The area is the function of the two dimensions.

If each dimension has changed by 10 times, the the area will change by:

10*10 = 100 times

Correct choice is C

Recall the relationship Between side and area

a/b=a²/b²

So

If it's multiplied by 10

The area increases by

Carl can do a particular job in 4 hours. It takes Mike 7 hours to do the same job. Approximately how long will it take them to do the same job working together?​

Answers

Answer:

28/11hr or about three hr

Step-by-step explanation

1/4+1/7=11/28

or 28/11 hr

Answer:

2 hours and 32.7 minutes. This is a good problem to become familiar with. It comes up in physics quite frequently.

Step-by-step explanation:

1 job/4 hours + 1 job / 7 hours = 1/x

1/4 + 1/7 = 1/x

(7 + 4)/28 = 1/x

11/28 = 1/x

x / 1 = 28/11

x = 2.54 hours repeating.

1 hour = 60 minutes

0.54 hours = x minutes

1/.54 = 60/x

x = 0.54 * 60

x = 32.7 minutes

Answers

Answer:

She can water 20 plants

Step-by-step explanation:

She has a total of 2 liters in each can, and if she uses 2 full cans, she has a total of 4 liters. 4 liters=4000 milliliters.

To find the amount of plants she can water, we need to divide the amount of water she has by how much it takes to water each plant. So,

[tex]\frac{4000}{200}[/tex]

[tex]=\frac{20}{1}[/tex]

[tex]=20[/tex]

So, she can water 20 plants with two full water cans.
