Answer:
The Mean is 7.
Step-by-step explanation:
Mean, or average is when you find a number that is reperesentative of the set as a whole.
To find this we add up all the values and divide it by how many values there are.
11 + 7 + 2 + 8 = 28
28/4 = 7
mean=7
n=4
sum =11+7+2+8=28
MEAN=sum/n=28/4=7
c = 9
9c - 10 = 2c + 53
9c =2c + 63
7c = 63
60
