Answer:

(\frac{1}{2},\frac{5}{2})

Step-by-step explanation:

To find the midpoint of a segment of line we have thenext expression:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Then using our endpoints: (3,5) and (-2,0) we have x_1=3,\,\,x_2=-2 and y_1=5,\,\,y_2=0. Now using that values in the expression of midpoint:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})=(\frac{3+(-2)}{2},\frac{5+0}{2})=(\frac{3-2}{2},\frac{5}{2})=(\frac{1}{2},\frac{5}{2})

Then the answer is:

(\frac{1}{2},\frac{5}{2})

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
Sav [38]

Answer:

y=4x+31

your answer will have a line that

3 is your y-intercept located at your y-axis

and 4x your slope.

we start from our point on the y-axis 31

and rise/run

rise over run = 4/1

rise 4

run 1

so move up 4

and to the right 1

Step-by-step explanation:

Since there is no image for me to tell you which line it is you can easily find out by chancing this expression to y=mx+b form. also known as slope intercept form.

y-3=4(x+7)

we want to do order of operations. pemdas

so first we do Parenthesis to do so we need to distribute the 4.

after we do so we get...

y-3=4x+28

now we need to move -3 to isolate y

to do so we need add 3

y=4x+31

In testing the hypotheses H 0 colon space mu space equals space 800 space v s. space H 1 colon space mu not equal to space 800,
steposvetlana [31]

Answer:

The <em>p</em>-value is 0.0802.

Step-by-step explanation:

The hypothesis for a test is defined as:

<em>H₀</em>: <em>μ</em> = 800 vs. <em>Hₐ</em>: <em>μ</em> ≠ 800

A two tailed test for the population mean can be performed using a <em>z</em>-test or a <em>t</em>-test.

A <em>z</em>-test is used if the data provided has information related to the population standard deviation and the sample size is large, i.e. <em>n </em><u>></u> 30.

And if the population standard deviation is not known and the sample size is small, then the <em>t</em>-test will be used.

Since there is no information about either the population standard deviation or the sample size, assume that <em>z</em>-test is used.

The test statistic value is:

<em>z</em> = 1.75

Compute the <em>p</em>-value of the test as follows:

p-value=2\times P(Z>z)\\

               =2\times (1-0.9599)\\=2\times 0.0401\\=0.0802

*Use a <em>z</em>-table for the probability.

Thus, the <em>p</em>-value is 0.0802.
