Question

Use the data below to complete the following calculation 58,85,14,59,79,92,61,50

Answer 1

Okay, here we need to calculate the summation of the data, lets do it:

`\sum ^{}_{}x=58+85+14+59+79+92+61+50=498`

`\sum ^{}_{}x^2=58^2+85^2+14^2+59^2+79^2+92^2+61^2+50^2=35192`
`(\sum ^{}_{}x)^2=(58+85+14+59+79+92+61+50)^2=(498)^2=248004`
