Answer:


\huge \boxed{{x=5}}

Explanation:

The mean is the average value of a data set.


\displaystyle \sf mean = (sum \ of \ terms)/(number \ of \ terms)

The mean is given solve for x.


\displaystyle 8 = (3+2+x+11+13+14)/(6)

Multiply both sides by 6.


\displaystyle 8(6) = (3+2+x+11+13+14)/(6) * (6)


48=3+2+x+11+13+14

Combine the numbers on the right side of the equation.


48=x+43

Subtract 43 from both sides.


48-43=x+43-43


5=x

Answer:

x=5

Explanation:

To find the mean, add up all the numbers and then divide by the number of numbers

(3+ 2+x+ 11+ 13+14)/6 = 8

Multiply each side by 6

(3+ 2+x+ 11+ 13+14) = 48

Combine like terms

43+x = 48

Subtract 43 from each side

x =5
