Question

Someone help me please

Answer 1

Explanation:

This symbol is signma, which is the sub of all the X's after plugging them into the equation.

Just to show the pattern, the first 3 numbers on your table are 15, 13, and 13... doing those 3 with Sigma, and simplifying

`( {1 5 - 2)}^(2) + ({13 - 2)}^(2) + {(13 - 2)}^(2)`

`169 + 121 + 121`

You would pretty much do that all the way down the list.

After doing so, we wind up with

15, 13, 13, 4, 19, 12, 6, 5, 14

`169 + 121 + 121 + 4 + 289 + 100 + 16 + 9 + 144`

Adding these together gets your answer of:

`973`
