Find the mean of the folowing integers: 5,-7,12,-10,15. Also:-16,-27,21,-19,14,-3 Sorry about the extra work.

  • math -

    "pernounced" is pronounced "pronounced."

    #1: each number is .2 times the previous one.

    #2. the mean is just the sum divided by how many there are:

    (5,-7,12,-10,15)/5 = 3
    (-16,-27,21,-19,14,-3)/6 = -5
