[AI-generated answer — Bot GPT 3.5]

To find the missing value of x, we can use the formula for calculating the mean:

Mean = (sum of all numbers) / (number of values)

Given that the mean is 89 and the other numbers are 94, 93, 85, 95, 81, 72, and 95, we can calculate the sum of all these numbers:

94 + 93 + 85 + 95 + 81 + 72 + 95 + x = 89 * 8
615 + x = 712
x = 712 - 615
x = 97

Therefore, the missing value of x is 97, and not 73.
