Answer:

Following are the responses to the given choices:

Step-by-step explanation:

In step 1:

State the zero and alternate test hypotheses. Insert underneath.

[tex]H_0 : \mu = 24: H_a : \mu < 24[/tex]

[tex]H_0[/tex] Smaller companies in their region are and they spend at least 24 hours per week on the marketing of the these companies

[tex]H_1[/tex] There really is no growth for smaller firms in their area because the companies spend or less 24 hours per week on marketing.

In step 2:

Each test statistics meaning is calculated. Around two decimal places for your reply.

[tex]z=\frac{\bar{X}-\mu_{0}}{\frac{\sigma}{\sqrt{n}}}=\frac{23.2-24}{\frac{4.2}{\sqrt{88}}}=-1.787[/tex]

In step 3:

Draw a start and write the decision.

Since it is observed that [tex]z=-1.787 < z_c=-1.64[/tex] it is then concluded that the null hypothesis is rejected.

Consequently we consider that small companies in their field may not expand, as they spend or less 24 hours per week on marketing.

The slope of the considered roof which has a rise of 10 feet and a run of 15 feet is 2/3

Slope of a line or straight object is the ratio of how much amount of rise occurs in correspondence to the increament in the run.

Thus, we get:

Slope = rise/ run

For this case, we're specified that:

The rise in roof = 10 ft and the run of 15 ft.

Thus, we get:

Slope = rise / run = 10/15 = [tex]\dfrac{5 \times 2}{5 \times 3} = \dfrac{2}{3}[/tex]

Thus, the slope of the considered roof which has a rise of 10 feet and a run of 15 feet is 2/3

Answer:

(51.90 - 37.50) / 3 = G

14.40 / 3 = G

4.8 = G

Savannah will be able to use 4 gigabytes to stay within her budget.

Step-by-step explanation:

Given that under her cell phone plan, Savannah pays a flat cost of $ 37.50 per month and $ 3 per gigabyte, and she wants to keep her bill at $ 51.90 per month, to determine which equation or tape diagram could be used to represent the context if g represents the number of gigabytes of data Savannah can use while staying within her budget, the following calculation should be performed:

(51.90 - 37.50) / 3 = G

14.40 / 3 = G

4.8 = G

Therefore, Savannah will be able to use 4 gigabytes to stay within her budget.

Answer: 75%

Step-by-step explanation:

We convert 2 litres into 1000ml which leaves us with:

750/1000 x 100 = 75%

Answer:

37.5%

Answer:

The test statistic needed to evaluate the claim is t = -1.08.

Step-by-step explanation:

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the expected value of the mean, s is the standard deviation of the sample and n is the size of the sample.

At a certain university, the average attendance at basketball games has been 3125. The athletic director claims that the attendance is the same as last year.

This means that [tex]\mu = 3125[/tex]

Due to the dismal showing of the team this year, the attendance for the first 9 games has averaged only 2915 with a standard deviation of 585.

This means that [tex]n = 9, X = 2915, s = 585[/tex]

What is the test statistic needed to evaluate the claim?

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{2915 - 3125}{\frac{585}{\sqrt{9}}}[/tex]

[tex]t = -1.08[/tex]

The test statistic needed to evaluate the claim is t = -1.08.

Answer:

  A.  (4, 12)

Step-by-step explanation:

Adding the second equation to twice the first will eliminate y.

Options aren't given in the question. However a concise explanation will be given.

Answer:

Length = 1 ; width = 2 and vice versa

Length = 0.5 ; width = 2.5 and vice versa

Step-by-step explanation:

The perimeter of a rectangle is obtained using the formular :

Perimeter = 2(length + Width)

Hence the sum of the length and width of the rectangle multiplied by 2 should give 6

Hence, possible dimension will. Include :

A dimension whereby the sum of length and width gives 3

Length = 1 ; width = 2 and vice versa

Length = 0.5 ; width = 2.5 and vice versa

These are possible dimension of the rectangle which has a perimeter of 6

Answer:

The expected gain per warranty is $27.65, crazy stuff

Step-by-step explanation:

If the estimate is right, there is a 0.1% probability for each extended warranty that the company has to shell out $350 (we disregard the situation where the replacement fails too, because there is no info that lets us deal with that).

This brings us to cost for the company equal to 0.1%*$350 per warranty sold.

0.1%*$350 = 0.001*$350 = $0.35

And the company gets $28 for each warranty sold, hence they earn

$28 - $0.35 = $27.65

on average.

Answer:

0.54 or 54%

Step-by-step explanation:

P( 1st but not second) = P(1st) - P(1st and Second) = 0.4 - 0.28 = 0.12 = 12%

P( 2nd but not first) = P(2nd) - P(1st and Second) = 0.7 - 0.28 = 0.42 = 42%

Probability of 1 of them (exactly one) = P( 1st but not second) + P( 2nd but not first) = 0.12 (12%) + 0.42 (42%) = 0.54 or also 54%.

Hope this helps!
