i see now. thank a lot

im really bored wrote:

for the first part to find the mean just add all the numbers together like this:

8 + 7 + 7 + 5 + 3 + 2 + 2 = 34 then you divide that answer by the amount of terms or the amount of numbers, which is 7. so then it would look like this: 34/7 which simplifys down to 4 6/7.

i dont understand: your mean 46/7 or 4*6/7 but 4*6= 24 please explain again for me. Thanks
