Question

The Watson have always kept a garden of Geometrees in their yard. The data table and scatter plot below represent the number of years for their longest living Geometree and how tall it has grown in feet. If the linear model applies the function f(x) = 1.3x + 9.2, what is the predicted value and residual when the tree is 3 years old with a height of 14?

Predicted value: 13.1 Residual: 0.9
Predicted value: 11.8 Residual: 0.2
Predicted value: 15.7 Residual: 1.3
Predicted value: 18.3 Residual: 0.7

Answer 1

Predicted value:13.1 residual 0.9

Explanation:

this is because if the predicted value is 13.1 the residual or left over 0.9. a simple strategy is subtract the predicted value from the actual value to find the residual.
