The mean is calculated by adding all the data values together, and then dividing the sum by the number of data values.
12+10+11+13+14+10+12+13+14=109
109÷9≈12.1
<u>The mean of the data set is about 12.1.</u>

General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Translate</u>
"Five" = 5
"times" is multiplication
"difference" is subtraction
"twice" means 2 times something
"a number" = <em>x</em>
"is" means equal
"-10" = -10
<u>Step 2: Set up equation</u>
5(2x - 4) = -10
<u>Step 3: Solve for </u><em><u>x</u></em>
- Distribute 5: 10x - 20 = -10
- Isolate <em>x </em>term: 10x = 10
- Isolate <em>x</em>: x = 1
Answer: TRUE
