Answer 2

Answer:

Value of x is 7.

Step-by-step explanation:

We are given that Mean of 3, 5, 9, x and 11 is 7.

Mean formula = (Sum of all values) ÷ (Number of observations)

         7     =  $\frac{3+5+9+x+11}{5}$

         35   =  28 + x

         x = 35 - 28 = 7

Therefore, value of x in data is 7.
