a survey of a group of seventh graders and a group of teachers at a local middle school asked how many siblings they each have. the dot plots below show the results.

based on the shape of the two dot plots, which statements correctly compare them? select three choices.
the center of the data for students has a value less than that of the center of the data for teachers.
the center of the data is to the right of the dot plot for both teachers and students.
there is a greater variation in the data for teachers than for students.
both sets of data cluster around 2.
the same number of teachers as students were surveyed.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
