Answer

Explanation:

Step1: Calculate predicted value

Substitute $x = 3$ into $y = 2.69x-7.95$. So, $y_{predicted}=2.69\times3 - 7.95=8.07 - 7.95 = 0.12$.

Step2: Calculate residual value

Residual = $y_{actual}-y_{predicted}$. From the table, when $x = 3$, $y_{actual}=1.0$. So, residual $=1.0 - 0.12=0.88$.

Answer:

0.88
