Answer:

36

Step-by-step explanation:

If there are 9 apartnments for everyletter 9 times the four letters is 36

9 * 4 = 36

The total number of apartments if The apartments in Greg's building are named using the letters A, B, C, and D, and the digits 1 through 9, are 36.

A combination is a choice of items from a group of different items, where the order of the choices is irrelevant.

Given:

The apartments in Greg's building are named using the letters A, B, C, and D and the digits 1 through 9,

Calculate the total number of apartments as shown below,

The number of apartments = total number of digits × total number of letters,

The number of apartments = (1, 2, 3, 4, 5, 6, 7, 8, 9) × (A, B, C, D)

The number of apartments = 9 × 4

The number of apartments = 36

Thus, The total number of apartments is 36.

Answer:

B) 264 units²

Step-by-step explanation:

Figure 1:

A = 1/2BH

A = 1/2 12(4)

A = 1/2 48

A = 24

Figure 2:

24 - 4 = 20

20 x 12 = 240

Total area:

Answer:

x = 12 , x = 7

Step-by-step explanation:

x-2 = 10

x= 10+2 = 12

x+6 = 13

x=13-6

x=7

Answer:

x = 9.5

If they were separate equations,

x - 2 = 10 ⇒ x = 12

x + 6 = 13 ⇒ x = 7

Step-by-step explanation:

x - 2 + x + 6= 10 + 13

2x + 4 = 23

2x + 4 - 4 = 23 - 4

2x = 19

2x ÷ 2 = 19 ÷ 2

x = 9.5

If they were separate,

x - 2 = 10

x - 2 + 2 = 10 + 2

x = 12

x + 6 = 13

x + 6 - 6 = 13 - 6

x = 7

Answer:

The volume of 1 bucket is 2.4 liters.

Step-by-step explanation:

We know that the volume of 12 buckets is the same as the volume of 9 bottles:

[tex] 12B = 9b [/tex]  

[tex] B = \frac{9}{12}b = \frac{3}{4}b [/tex]   (1)

Where B is for buckets and b is for bottles.

Also, that the total volume of 3 bottles and 5 buckets is 21.6 liters:

[tex] 5B + 3b = 21.6 [/tex]   (2)

We can calculate the volume of 1 bucket by entering equation (1) into (2):

[tex] 5(\frac{3}{4}b) + 3b = 21.6 [/tex]

By solving for "b" we have:

[tex] b = \frac{21.6*4}{27} = 3.2 [/tex]

Now, the volume of 1 bucket is:

[tex] B = \frac{3}{4}b = \frac{3*3.2}{4} = 2.4 [/tex]

Therefore, the volume of 1 bucket is 2.4 liters.

Answer:

m<A = 40°

m<C = 113°

Step-by-step explanation:

Problem 1:

m<A = ½(arc BC) (Inscribed angle theorem)

Substitute

m<A = ½(80°)

m<A = 40°

Problem 2:

Given that m<A = 67°

Recall: angels that are opposite each other in any given inscribed quadrilateral are supplements of each other.

Thus, it implies that:

m<A + m<C = 180°

Substitute

67° + m<C = 180°

Subtract 67° from each side

m<C = 180° - 67°

m<C = 113°

Step-by-step explanation:

You take the original and then You look at the place value to the right. If it is 5 or more you round up if it is less you keep it the same. 359.006. 6 is more than five so you will round up. your answer then becomes 359.01

Answer:

Sidney played 5 games and rode 8 rides.

Step-by-step explanation:

Since Sydney is going to a carnival that has games and rides, and each game costs $ 1.25 and each ride costs $ 2.25. Sydney spent $ 24.25 altogether at the carnival and the number of rides she went on is 3 more than the number of games she played, to determine the number of games Sydney played and the number of rides Sydney went on the following calculation must be performed:

5 x 2.25 + 2 x 1.25 = 11.25 + 2.50 = 13.75

6 x 2.25 + 3 x 1.25 = 13.50 + 3.75 = 17.25

7 x 2.25 + 4 x 1.25 = 15.75 + 5 = 20.75

8 x 2.25 + 5 x 1.25 = 18 + 6.25 = 24.25

Therefore, Sidney played 5 games and rode 8 rides.

Syndey played 5 games and rode 8 rides

Answer:

151 students must be selected.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

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

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

The population standard deviation is known to be $25.

This means that [tex]\sigma = 25[/tex]

How many students must be randomly selected to estimate the mean weekly earnings of students at one college? Sample mean within $4 of the population mean

This is n for which M = 4. So

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

[tex]4 = 1.96\frac{25}{\sqrt{n}}[/tex]

[tex]4\sqrt{n} = 1.96*25[/tex]

[tex]\sqrt{n} = \frac{1.96*25}{4}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*25}{4})^2[/tex]

[tex]n = 150.1[/tex]

Rounding up:

151 students must be selected.

Answer:

The 99% confidence interval for the true proportion of all college students who own a car is (0.315, 0.463).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

When 293 college students are randomly selected and surveyed, it is found that 114 own a car.

This means that [tex]n = 293, \pi = \frac{114}{293} = 0.389[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.389 - 2.575\sqrt{\frac{0.389*0.621}{293}} = 0.315[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.389 + 2.575\sqrt{\frac{0.389*0.621}{293}} = 0.463[/tex]

The 99% confidence interval for the true proportion of all college students who own a car is (0.315, 0.463).
