The table and scatter plot show the number of hours worked, x , and the amount of money spent on entertainment, y, by each of 10 students. The equation of the line of best fit is y=0.3x+24.00 Use the equation of the line of best fit to fill in the blanks below. Give exact answers, not rounded approximations.

The observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Observed amount:

At x = 7.9, y = $33.50

At x = 25.00, y = $25.00

We have a line of best fit:

y=0.3x+24.00

At x = 7.9

Predicated amount:

y = $26.37

At x = 12.1

Predicated amount:

y = $27.63

Residual (when x = 7.9) = $33.50 - $26.37 = $7.13

Residual (when x = 12.1) = $25.00 - $27.63 = -$2.63

Thus, the observed amount are At x = 7.9, y = $33.50 and at x = 25.00, y = $25.00 predicted amount are At x = 7.9, y = $26.37 and At x = 12.1, y = $27.63 and residuals are $7.13 and -$2.63.
