Answer:
8
Step-by-step explanation:
To find the mean, add all the numbers together and divide by the amount of numbers there are.
(3 + 3 + 4 + 4 + 8 + 8 + 8 + 10 + 12 + 20)/10 = answer
Simplify. First, solve the parenthesis, then divide.
(80)/10 = answer
8 = answer
8 is the mean of the data set.

10.2 I do believe
Add all the Numbers together and divide your answer by the amount of Numbers there are.
Example: 3,3,4,4,8,8,8,10,12,20 there are 10 numbers there. Add all of those numbers together are 102.
102÷10 = 10.2
The answer is 18.
Just replace the x with 2
X + 20 <= -10
Subtract 20 from both sides:
X <= -30
m=-2n-13
m+1=-2(n+6)
m+1=-2n-12
-1. -1
