First, you need to draw this out. Roughly, it should look a little something like the link i included in this answer. then u just draw a line tracing the points to make a rectangle (sandbox) and decide that the perimeter, or the distance around, would be 3+4+3+4 = 14 feet.

Given the domain {-2,2,4} what is the range for the relation 9x+3y=6
OleMash [197]

Answer:

{8,-4,-10}

Step-by-step explanation:

re arrange relation, im going to assume x is the domain input and y is the range.

-3x+2=y

plug in every element of the set x to get the range set y

-3(-2)+2=y

y=8

-3(2)+2=y

y=-4

-3(4)+2=y

y=-10

so the range is {8,-4,-10}

Using the mean concept, it is found that the mean difference between the call times and the  company's average call time is given by:

  • C. 0.4

<h3>What is the mean?</h3>
  • The <em>mean </em>of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem:

  • The four observations are the differences between the time of each phone call and the average time.
  • They are: {-2.32, -1.55, 4.79, 0.68}

Hence, the mean difference is:

M = \frac{-2.32 - 1.55 + 4.79 + 0.68}{4} = 0.4

Hence, option C is correct.

To learn more about the mean concept, you can take a look at brainly.com/question/13451786
