If M is the mean of x1,x2,x3,x4,x5 and x6,prove that (x1−M)+(x2−M)+(x3−M)+(x4−M)+(x5−M)+(x6−M)=0

If M is the mean of x1,x2,x3,x4,x5 and x6,prove that (x1−M)+(x2−M)

1.	If M is the mean of x1,x2,x3,x4,x5 and x6,prove that (x1−M)+(x2−M)+(x3−M)+(x4−M)+(x5−M)+(x6−M)=0
Answer» $I f M i s t h e m e a n o f x_{1}, x_{2}, x_{3}, x_{4}, x_{5} a n d x_{6}, p r o v e t h a t (x_{1} - M) + (x_{2} - M) + (x_{3} - M) + (x_{4} - M) + (x_{5} - M) + (x_{6} - M) = 0$
