Answer:
The mean is 15
Explanation:
The x value that would get a median of 12 is three, which when taken the mean of the numbers when x is three, you get 15
The mean value of the given expressions with a median of 12 is: 7.
Mean = average of the data set.
Median = center value or average of the center values.
Given that the median for x, 2x, 6x, 11x is 12, therefore:
12 = (6x + 11x)/2
2(12) = 17x
24 = 17x
x ≈ 1.4
Mean = (x + 2x + 6x + 11x)/4 = 20x/4
Plug in the value of x
Mean = 20(1.4)/4
Mean = 7
