Question

The mean of x, y, and z is 9. If x + y = 16, then z equals to

  1. 12
  2. 11
  3. 10
  4. None of the above

hintHint:

fraction numerator x plus y plus z over denominator 3 end fraction equals 9

The correct answer is: 11


    Mean = 9
    fraction numerator x plus y plus z over denominator 3 end fraction equals 9
    x + y +z = 27
    16 + z = 27
    z = 11
