Answer:

<em><u>z = -3</u></em>

Step-by-step explanation:

<u>Step 1: Simplify both sides of the equation. </u>

z+7=−z+1

<u>Step 2: Add z to both sides. </u>

z+7+z=−z+1+z

2z+7=1

<u>Step 3: Subtract 7 from both sides. </u>

2z+7−7=1−7

2z=−6

<u>Step 4: Divide both sides by 2. </u>

<u>2z</u>   =  <u>−6 </u>

Solve for r <br> r/8 =7<br> r = ____
Nostrana [21]

Answer:

r=56

Step-by-step explanation:

Since, r divided by 8 gives 7, if you do the inverse function(which is basically like the reverse of the question)

you can multiply 8 and 7 to find the r.

So 8 times 7 gives 56.

And to check you can do

\frac{56}{8} which gives 7

You can tell me if my explanation is wrong. Thanks

A researcher claims that the average annual salary of part-time community college instructors is at least $45,000. To test this
Doss [256]

Answer:

See explanation

Step-by-step explanation:

Solution:-

- The researcher claims :

" the average annual salary of part-time community college instructors is at least $45,000 "

- We will extract the claim made by the researcher to be the Null hypothesis:

                     Null Hypothesis : μ ≥ $45,000

- Any statement otherwise, or point of rejection criteria will denote the Alternate hypothesis that disbands the claim that:

" the average annual salary of part-time community college instructors is less than $45,000 " :

                    Alternate Hypothesis : μ < $45,000

- This type of test with a sample size of n = 25 < 30 and population standard deviation is also not given hints the use t-test statistics and t-critical value reject the claim.

                     Lower tail - one sample - T-test.

Suppose f(x)=x^2.What is the graph of g(x)=f(5x)?
ZanzabumX [31]

Answer:

D

Step-by-step explanation:

g(x)=f(5x)

this means plugging in 5x for x in f(x):

g(x)=f(5x)=(5x)^2

which can be further simplified:

5^2x^2=25x^2

Since the coefficient of x being larger means a vertical stretch, the answer is D

example:

g(2)=f(5*2)=f(10)=f(10^2)=100

so for g(x), it has the coordinates (2,100), which is most definitely not C
