The following is a list of 5 measurements. 16,13,5,20,14 Suppose that these 5 measurements are respectively labeled

Explanation:

The fancy or strange looking E symbol is the greek uppercase letter sigma, to mean sum. So they want you to add the terms in the form x^2. The x values are from the list given to us.

x = 16 leads to x^2 = 256

x = 13 leads to x^2 = 169

etc etc

After squaring all the x values, we have this new list {256, 169, 25, 400, 196}

Lastly, you add up all the squared values to get the final answer of 256+169+25+400+196 = 1046

i think it is 70
