A.M of `a+d, a, a-d` is

If a,b,c are in G.P and A.M of a and b is x and A.M. of b and c is y then…….

a , b , c , d are in increasing G.P. If the AM between a and b is 6 and the AM between c and d is 54 , then the AM of a and d is

a , b , c , d are in increasing G.P. If the AM between a and b is 6 and the AM between c and d is 54 , then the AM of a and d is

The co-eff. Of variation of a data is 58%, S.D. of the data is 2.32 then the A.M. of the data is

The A.M. of variable x is 100. Then what will be the value of the A.M, of the variable (5x-10).

If x,y,z are in A.P and A_(1) is the A.M of x and y and A_(2) is the A.M of y and z then A.M of A_(1) and A_(2) is

A.M of 20 and 40 is…..

a , b , c , d are in increasing G.P. If the AM between a and b is 6 and the AM between c and d is 54 , then the AM of a and b is

a , b , c , d are in increasing G.P. If the AM between a and b is 6 and the AM between c and d is 54 , then the AM of a and b is

The sum of all the deviations of the observations of a data from its A.M is………a)zero b)maximum c)minimum d)negative number
