Answer:

Step-by-step explanation:

Well first we have to take 13 and multiply it be everything in the parentheses.

13(2n - 14) = 712

13*2n - 13* 14 = 712

26n - 182 = 712

Now we take 182 and add it to 712 to get 26n by itself.

26n = 894

Now I believe we divide...

I got 34.38461

I don't know if you can put decimals or if I did this wrong.. Sorry if I did this wrong. If you can put a decimal then you are going to have to round. :)

Hope this is somewhat helpful if not I am truly sorry. Have a wonderful day! :)

Blake gives piano lessons in the evenings.

Aliun [14]

Answer:

The correct answer is B. {0, 20, 40, 60, 80, 100, 120}

Step-by-step explanation:

1. Let's check all the information given to answer this question correctly:

Rate of each piano lesson Blake gives = US$ 20

Blake can give between 0 and 6 lessons every evening

Earnings = Number of lessons * Rate of each lesson

2. What is the range of this relation?

Let's recall that the domain of a relation is the set of all values for which the relation is defined, and the range of the relation is the set of all values that the relation takes.

It means that the domain of the relation in this case is the number of lessons that Blake can give every evening:

{0, 1, 2, 3, 4, 5, 6}

And the range of this relation is the amount Blake earns in an evening depending on the number of lessons he gives:

{0, 20, 40, 60, 80, 100, 120}

The correct answer is B. {0, 20, 40, 60, 80, 100, 120}

Consider an experiment to determine the effect of a single factor that can be set to a levels. At each factor setting n measurem

Stella [2.4K]

Answer:

(n-1)a

Step-by-step explanation:

In this question we have a single factor with number of levels equal to a.

Then the Number of observations that are within each factor setting is equal to n.

So the total number of observations = na.

We have the degrees of freedom for SS(Error) = n - k,

Now, n is the total number of observations,

While,

k is the number of levels of the single factor.

Therefore the degrees of freedom is = na - a

= (n - 1)a.
