To find mean/average it's fairly simple!! :)

The first thing you should do is add up the first numbers -
* 20 + 15 + 16 = 51 :)
* 16 + 19 + 17 = 52

Now divide each of the scores by the amount of numbers there is -
* 20 (1) 15 (2) 16 (3)
* 16 (1) 19 (2) 17 (3)

51 ÷ 3 = 17 (Rolanda's Average Score)
- Which # is bigger?
52 ÷ 3 = 17.3 (Jetta's Average Score)

Carlos find the absolute value of -5 3/10 and then find is the opposite of his answer Jason finds the opposite of -5 3/10 and th
a_sh-v [17]

we know that

5 \frac{3}{10}= \frac{5*10+3}{10} = \frac{53}{10}

Step 1

<u>Carlos's method</u>

1) <u>Find the absolute value of -\frac{53}{10}</u>

\left|-\frac{53}{10}\right|=\frac{53}{10}

2) <u>Find the opposite</u>

opposite=-\frac{53}{10}

Step 2

<u>Jason's method</u>

1) <u>Find the opposite of  -\frac{53}{10}</u>

opposite=\frac{53}{10}

2) <u>Find the absolute value </u>

\left|\frac{53}{10}\right|=\frac{53}{10}

Step 3

<u>Compare the answers</u>

\frac{53}{10} > -\frac{53}{10}

therefore

<u>The answer is</u>

The greater value is obtained with the method of Jason
