To determine whether the model is a good fit for the data in the table −

Answer to Problem 7E
The model isa good fit for the data in the table.
Explanation of Solution
Given:
Formula Used:
A residual is a measure of how well a line fits an individual data point. This vertical distance is known as a residual. For data points above the line, the residual is positive, and for data points below the line, the residual is negative. The closer a data point's residual is to
Calculation:
Residual | |||
Plotting the above points on the graph, we have:
From the above graph, we can see that the residuals form a straight line.
Thus, the model isa good fit for the data in the table.
Conclusion:
The model is a good fit for the data in the table.

There are blue tiles on the main diagonals and red tiles everywhere else. In all cases, both blue and red tiles must be used. and the two diagonals must have a common blue tile at the center of the floor. If 81 blue tiles will be used, how many red tiles will be needed? For what numbers in place of 81 would this problem still be solvable? Find an expression in k giving the number of red tiles required in general.arrow_forwardSolve questionsarrow_forward
