Answer:

The answer is C, 1.

Step-by-step explanation:

The answer is simple. You round up to the nearest whole number (cant be a negative,) and it can't be a 0. Therefore, you get 1.

Which of the following best represents the solution set to - 5(x+3) > - 3x + 5

love history [14]

Answer:

$x > - 10$

Step-by-step explanation:

$- 5(x+3) > - 3x + 5$

$- 5x - 15 > - 3x + 5$

$- 5x + 3x > 5 + 15$

$- 2x > 20$

$x > \frac{20}{ - 2}$

$x > - 10$

The area of the base of a prism is 125 square units, and it’s height is 5 units. What is the volume of the prism?

Reil [10]

Answer:

A. 625 cubic units

Step-by-step explanation:

The formula to find the volume of the prism = Base area * height.

Here the base area of the prism is a square, which is given as 125 square units.

Height = 5 units

The volume of the prism = 125 *5

= 625 cubic units

Hope this will helpful.

Thank you.

A survey recently reported that the mean national annual expenditure for inpatient and outpatient services of all persons over 6

zlopas [31]

Using the z-distribution, it is found that the p-value for this test is of 0.0375.

At the null hypothesis, it is tested if the expenses are the same as the national average, that is, of $5,423. Hence:

$H_0: \mu = 5423$

At the alternative hypothesis, it is tested if it is higher, hence:

$H_1: \mu > 5423$

We have the standard deviation for the population, thus, the z-distribution is used. The test statistic is given by:

$z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}$

The parameters are:

$\overline{x}$ is the sample mean.
$\mu$ is the value tested at the null hypothesis.
$\sigma$ is the standard deviation of the sample.
n is the sample size.

For this problem, the values of the parameters are: $\overline{x} = 5516, \mu = 5423, \sigma = 979, n = 352$

The value of the test statistic is:

$z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}$

$z = \frac{5516 - 5423}{\frac{979}{\sqrt{352}}}$

$z = 1.78$

The p-value is the probability of finding a sample mean above $5,516, which is 1 subtracted by the p-value of z = 1.78.

Looking at the z-table, z = 1.78 has a p-value of 0.9625.

1 - 0.9625 = 0.0375

Hence, the p-value for this test is of 0.0375.
