Mrs. myles gave the same test to both her first and third period class. in first period, the median was 75 and the range was 30. in third period, the median was 80 and the range was 60. which is a true statement? a) the lowest score was in third period. b) the highest score was in first period. c) on average, first period did better than third period. d) there is not enough information to know if any of these is true

the answer is 99.

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.
