Hello,

$\sum_{i=1}^n\ ( x_{i} -\overline{x})\\

=\sum_{i=1}^n\ x_{i} -\ \overline{x}\ \sum_{i=1}^n\ 1\\

=n*\overline{x}- \overline{x}*n=0

$

79.5%,

Step-by-step explanation:

each big square has 100 little squares inside, meaning there are 200 total between the two.

in total, 159 little squares are shaded.

if you divide, 159÷200= .795.

move the decimal to the right 2 spaces to get the answer of 79.5%

Hope this helps :)
