Find the residual values, and use the graphing calculator tool to make a residual plot.
2 answers:
<u>Answer-</u>
D. No, the points are in a curved pattern.
<u>Solution-</u>
The difference between the observed or given value of the dependent variable and the predicted value is called the residual. Each data point has one residual.
<em>If the points in a residual plot are randomly dispersed around the horizontal or x-axis, a linear regression model is appropriate for the data. Otherwise, a non-linear model is more appropriate.</em>
Plotting a graph, by taking the residual values on ordinate and values of given x on abscissa, a non-random U pattern is obtained.
So a non-linear model will be a better fit for this data set.

For this case, what we must do is find the surface area of the cube.
By definition, the surface area of a cube is given by:
Where,
L: length of the sides of the cube.
Substituting values we have:

Answer/Step-by-step explanation:
Recall: if two figures are similar, we know that the ratio of their areas = the square of the ratio of their corresponding sides
Apply this knowledge to solve the problems given.
✔️Problem 1 (4-sided polygon):
Let the missing area be x cm²
Therefore,
Multiply both sides by 9
x = 9*4
x = 36 cm²
✔️Problem 2 (3-sided polygon):
Let the missing area be y cm²
Therefore,
Multiply both sides by 240
y = ¹/16 × 240
y = 15 cm²
✔️Problem 3 (5-sided polygon):
Let the missing area be z cm²
Therefore,
Multiply both sides by 40
z = 90 cm²
