Answer-

D. No, the points are in a curved pattern.

Solution-

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.

$Residual\ value= Given\ value - Predicted\ value$

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.

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.

The length of a rectangle is twice its width.

Furkat [3]

The perimeter is the sum of all a shapes sides.

so if length is two times the width, you could write it as 2w.

2w + 2w + w + w = 42. Simplified, it's 6w = 42.
Divide both sides by 6, and you get w = 7.

Since the length is 2w, 2 * 7 = 14, so the length is 14

Area of rectangle is length * width, so do 14 * 7 which is 98. Slap on some units and your answer is 98 sq m

A rectangle has vertices H(3,0), I(3,7), J(6,7) , and K(6, 0) . Use the coordinates to find the perimeter of the rectangle. _uni
