Answer 2

Answer:

Empirical formula of mean ,median and mode is 3 median = 2 mean + mode

Given the value of mode is 12 and median is 8.

Then, substitute the value of mode and median in formula, we have :

=> 3 median = 2 mean + mode

=> 3 x 8 = 2 mean + 12

=> 24 - 12 = 2 mean

=> 12 = 2 mean

=> 6 = mean

Therefore, the value of mean is 6.
