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)
Answer:
fourth option
Step-by-step explanation:
Given
3x < - 9 ( divide both sides by 3 )
x < - 3
solution set is { x | x < - 3 }
we know that

Step 1
<u>Carlos's method</u>
1) <u>Find the absolute value of
</u>

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

Step 2
<u>Jason's method</u>
1) <u>Find the opposite of
</u>

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

Step 3
<u>Compare the answers</u>

therefore
<u>The answer is</u>
The greater value is obtained with the method of Jason
