Answer:

B

Step-by-step explanation:

Answer:

0.8%

Step-by-step explanation:

First, convert 7.5 m to cm.

There are 100 cm in one meter, so to convert this, multiply 7.5 by 100:

7.5(100)

= 750

So, there are 750 cm in 7.5 m.

To find the percent of 6 cm, divide 6 by 750, then multiply by 100:

(6/750) x 100

= 0.008 x 100

= 0.8

So, 6 cm as a percentage of 7.5 m is 0.8%

Answer:

A) C(x)=4x³+8x²+8x+16

Step-by-step explanation:

(4x²+8)(x+2)=

A) 4x³+8x²+8x+16

The capacity of the box would be the volume.

Multiply the area by the height:

4x^2 + 8 times x+2

Multiply each term by each term:

4x^2 * x = 4x^3

4x^2 * 2 = 8x^2

8 * x = 8x

8*2 = 16

Combine the terms to get:

4x^3 + 8x^2+ 8x +16

The answer is A. C(x) = 4x^3 + 8x^2 + 8x + 16

Answer:

Any expression doesn't have the same value

Step-by-step explanation:

Subtract 82 from 23.

−59

Simplify each term.

Multiply 8 by 2.

23−1⋅16

Multiply −1 by 16.

23−16

Subtract 16 from 23.

7

Subtract 8 from 23.

Answer:

Justin has 10 nickels and 5 dimes.

Step-by-step explanation:

Given that Justin has x nickels and y dimes, and he has a minimum of 15 coins worth at most $ 1 combined, to determine one possible solution the following calculation must be performed:

Nickel = 0.05

Dime = 0.10

15 x 0.05 + 0 x 0.1 = 0.75

14 x 0.05 + 1 x 0.1 = 0.80

13 x 0.05 + 2 x 0.1 = 0.85

12 x 0.05 + 3 x 0.1 = 0.90

11 x 0.05 + 4 x 0.1 = 0.95

10 x 0.05 + 5 x 0.1 = 1

So, Justin has 10 nickels and 5 dimes.

THIS IS ONLY WHAT I THINK! WAIT FO RMORE RESPONSES IF NEEDED! THANK YOU.

the answer is "A" or "D" but I am prettu sure its "A"

Solution :

The population of the interest is : All smokers

The parameters of the interest is : population mean number of the cigarettes per day.

Population of interest :

The population interest is defined as the group or the population form the sample from which the experimenter or the researcher draws results or the conclusion of the experiment.

In the context, the researcher wants to draw the results from all the smokers in the study, so the population of interest is the smokers.

Parameter of interest :

The parameters of interest is the set of all unknown numbers which describes the population from which the researcher wishes to test with the estimator.

In the context, the interest parameter is the mean or the average population number of the cigarettes per day.

Answer:

[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]

Option d.

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 zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

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

79 percent of adults age 18 years and older in the United States use the Internet.

This means that [tex]\pi = 0.79[/tex]

98% confidence level

So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.33[/tex].

Which of the following should be used to find the sample size (n) needed?

We have to find n for which [tex]M = 0.025[/tex]

So the equation is:

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

[tex]0.025 = 2.33\sqrt{\frac{0.79*0.21}{n}}[/tex]

Option d.

Answer:

you answer will be x=9 , y=18
