If M is the mean of x,y,z ; then what is the mean of x+5,y+5 and z+5	Choose the correct choice from the following choices
A) M  B) 3M  C) 10M  D) M+10  E) M+5
If each number is shifted up by 5, the mean also shifts up by 5 since it stays in the middle. The whole set is shifted on the number line so mean will also shift by the same amount.   So new mean is M + 5.   Answer (M+5)
