Nnesha (nnesha):

how is that right ??

OpenStudy (solomonzelman):

is there a point in reporting, or not?

OpenStudy (anonymous):

your not supposed to give direct answers. 18 + 20 + 10 + 22 = 70, then you divide by 5 since there are 5 numbers. that's how you find the mean.

OpenStudy (solomonzelman):

dividing by 4, not 5

Nnesha (nnesha):

not 5 numbers

OpenStudy (anonymous):

OpenStudy (anonymous):

18 + 20 + 10 + 22 = 70 / 4 = the answer. can you do that ?

OpenStudy (solomonzelman):

The idea is that you add all the numbers, and divide the sum by the number of numbers. \(\scriptsize\color{ slate }{\scriptsize{\bbox[5pt, royalblue ,border:2px solid royalblue ]{~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ }}}\)\(\large\color{black}{ \displaystyle \\[0.8em]}\) example 1 the average between 1, 4, 11, 12 is?\(\large\color{black}{ \displaystyle \\[0.5em]}\) \(\large\color{black}{ \displaystyle \frac{1+4+11+12 }{4}=\frac{28 }{4}=7 }\) \(\scriptsize\color{ slate }{\scriptsize{\bbox[5pt, royalblue ,border:2px solid royalblue ]{~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ }}}\)\(\large\color{black}{ \displaystyle \\[0.8em]}\) example 2 the average between 2, 9, 17, 19, 23 is?\(\large\color{black}{ \displaystyle \\[0.5em]}\) \(\large\color{black}{ \displaystyle \frac{2+ 9+17+19+23 }{5}=\frac{60 }{5}=12 }\)
