Which of the following is not a requirement for regression analysis? Choose the correct answer below. A. The method for regression analysis line is not robust. It is seriously affected by a small departure from a normal distribution. B. The sample of paired (x, y) data is a random sample of quantitative data. C. Outliers can have a strong effect on the regression equation, so remove any outliers if they are known to be errors. D. Visual examination of the scatterplot shows that the points approximate a straight-line pattern.

the correct answer is the second option

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
