Question

if x baar = 18 and z = 24 , then M = ?​ step by step​

Answer 1

Answer:

20

Step-by-step explanation:

If mode = z , median = M,

Mean = x then

z = 3M - 2x

Or

M = ( z + 2x )/3

Here ,

z = 24 , x = 18 ,

M = ( z + 2x )/3

=> M = ( 24 + 2 × 18 )/3

=> M = ( 24 + 36 )/3

=> M = 60/3

=> M = 20

Answer 2

By empharical formula

If mode = z and median = M

Mean = x

z = 3m-2x

or

M = (z+2x)/3

Here,

z= 24 ; x=18

M = (z+2x)/3

M= (24+2×18) / 3

M = (24 + 36 ) /3

M = 60/3

M = 20
