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.

A square has a side length of 5 and 1/4 inches what is the area of a square

padilas [110]

Answer: 27.5625 or 27.6

Explanation:
A square has even side lengths so each side equals 5 1/4 or 5.25. So you take two sides and multiply them together. In other words, 5.25•5.25. Then you get roughly 27.6 rounded

1 A line passes through (0, 2) and has a slope of 3. Which function's graph is parallel to this line?

motikmotik

D. y=mx+b. m being slope and b being the y intercept. so the equation for the line is y=3x+2 and to be parallel your m must be the same number so D. 3x
