[pre algebra] need some help

  1. Feb 7, 2006 #1
    I know this is basic stuff, but i'm barely geting back into school and starting off with a basic math class, so any help would be highly appreciated, i don't want the answers just to be pointed in the right direction. :smile:


    'what is the average (arithmetic mean) of 8,7,7,5,3,2 and 2'

    (a) [tex]3\frac{4}{7}[/tex]

    (b) [tex]4\frac{5}{6}[/tex]

    (c) [tex]4\frac{6}{7}[/tex]

    (d) 5

    (e) [tex]6\frac{4}{5}[/tex]

    Just add them all up, and divide by the total number of numbers you have.

    so the answer is (c) [tex]4\frac{6}{7}[/tex]


    which i got by adding the numbers up which is 34 and dividied by that total which is 7, so 34 divided by 7 is 4 remainder 6 which gives me [tex]4\frac{6}{7}[/tex]


    right?
