Question

in statistics if 3M-2Md=60 then Mo = ?

Answer 1

Answer:

Step-by-step explanation:

Here M-Mean

Md-Median and Mo - Mode:

Given that ;

3 Mean - 2 Median = 60

We know that =

Mean - Mode = 3 (Mean - Median);  we can write it as :

Mode = Mean - 3 mean +3 Median;

Mode = 3Median-2Mean; Median = 1/3(Mode+2Mean)

Putting  Median = 1/3(Mode+2Mean) in eq. 3 Mean - 2 Median = 60 ;

3 Mean - 2/3 (Mode+2Mean) = 60;

(3-4/3) Mean - 2/3 Mode = 60;

(5/3)Mean-(2/3)mode = 60;

Mode = 2.5 Mean -90
