Answer:

Step-by-step explanation:

Since the input is -4, x = -4. The equation then is y = -7(-4) -2

A negative times a negative is a positive, so -7 times -4 is 28.

Now the equation reads y = 28 - 2

Then obviously you just subtract the two and then you get 26.

6 x 9 x 1/2 = 27cm^2

Exciting Entertainment

We can deduce that the student's gender provides information about their entertainment choices.

<u>Given the following data:</u>

Expenses on digital music = $2.6 billion dollars.

Expenses on video games = $24.7 billion dollars.

<h3>Describing and analyzing the data.</h3>

The data was gathered from a random survey which was conducted by sixth-grade students to determine the number of digital music (songs) that was downloaded by each student to their respective media player in the past two months as shown in the table in the image attached below.

<h3>What is a median?</h3>

A median can be defined as the <u>middle number</u> (center) of a sorted data set, which is when the data set is arranged from the least to greatest (ascending order) or greatest to least (descending order).

<u>For the </u><u>girls</u><u>:</u>

Median = 50.

Median = 33.

A mean refers to a ratio of the sum of the total number in a data set to the frequency of the data set.

<u>For the </u><u>girls</u><u>:</u>

Mean = 46.

Mean = 34.

In this context, we can deduce that the student's gender provides information about their entertainment choices.
