    The mean is the average of the numbers, so if x = all 11 numbers added together, then you have the equation:

    x / 11 = 7, so x = 77 (this is all of the numbers added together)

    if the number 13 is removed, the equation becomes:

    (77 - 13) / 10 = M (M is the new mean)

    so the new mean is 6.4
