Answer:

The value of x is 13.

Step-by-step explanation:

  • Mean is the sum of all the observations in a data set divided by the total number of observations.
  • The observations be  6,5+x,28,18,11.
  • Number of observations = 5
  • Mean =  Sum of observations / Total number of observations

        14 = \frac{6+5+x+28+18+11}{5}

        14 =  \frac{11+x+28+18+11}{5}

        14 = \frac{x+ 22+28+18}{5}

Upon cross-multiplication,

         14*5 = x + 22+28+18

          14*5 = x +57

               70 = x +57

                x = 70-57

                x = 13

Therefore, value of x is 13.
