Alonzo describes a histogram as having a cluster from 20–50, a frequency of 0 from 10–20, and a peak at 40–50. Which histogram is he describing? A histogram titled Reading logs with number of pages on the x-axis and students on the y-axis. 1 student read 0 to 10 pages, 0 read 10 to 20, 8 read 20 to 30, 12 read 30 to 40, and 18 read 40 to 50. A histogram titled Reading logs with number of pages on the x-axis and students on the y-axis. 1 student read 0 to 10 pages, 8 read 10 to 20, 0 read 20 to 30, 12 read 30 to 40, and 18 read 40 to 50.

Step-by-step explanation:

In the histogram described by the first option, the peak (18) is located at 40-50. Also, a frequency of zero is observed for range 10-20. The cluster from 20–50 means that most of the data is between this range, in fact, only 1 point is located at range 0 - 10, outside this cluster.

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.
