Answer:

The total number of girls is 47.

Step-by-step explanation:

Below are the following values:

Total number of students = girls + boys

Total number of students = 47 + 324

Total number of students = 371

We are required to find the number of girls in the school.

Since a total number of boys is 324 and thus total number of girls is 47.

Select the equations where x = 8 is the solution. Select all that apply (select 3).

seraphim [82]

Answer:

Step-by-step explanation:

1. x - 2 = 10

x = 10 + 2 = 12

2. 40 = 5x

40/5 = x

x = 8

3. x/2 = 8

Multiply by 2 on both sides

x = 16

4. x + 14 = 24

x = 24 - 14 = 10

5. x + 2 = 10

x = 10 - 2 = 8

6. x/8 = 1

Multiply by 8 on both sides

x = 8

No 2 5 and 6 is the correct answer

Using the slope concept, it is found that the rate of download of the file is of 1920 MB/s.

<h3>What is the slope?</h3>

The slope of a linear function is given by the <u>change in the output divided by the change in the input</u>.

In this problem:

3 minutes since resuming the download 6720 total MegaBytes (MB).

5 minutes since resuming the download 10560 total MegaBytes (MB) of the file had been downloaded..

Hence, in 2 minutes, there was a change of 10560 - 6720 = 3840 MB, which means that the slope is:

$m = \frac{3840}{2} = 1920$

The rate of download of the file is of 1920 MB/s.

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 280 engines

DENIUS [597]

Answer:

The value of the test statistic is $t = -2.09$

Step-by-step explanation:

The null hypothesis is:

$H_{0} = 6.6$

The alternate hypotesis is:

$H_{1} \neq 6.6$

Our test statistic is:

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, $\sigma$ is the standard deviation(square roof of the variance) and n is the size of the sample.

In this problem, we have that:

$X = 6.5, \mu = 6.6, \sigma = \sqrt{0.64} = 0.8, n = 280$

$t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}$

$t = \frac{6.5 - 6.6}{\frac{0.8}{\sqrt{280}}}$

$t = -2.09$

The value of the test statistic is $t = -2.09$
