Will make the following data show the scores of some students in a competition: 12 points, 21 points, 29 points, 17 points, 24 points, 23 points, 28 points which box plot represents the data?

D

Step-by-step explanation:

First put the data from smallest to largest

12 points, 17 points,21 points,  23 points, 24 points, 28 points,29 points

The left end of the whisker should be 12  (This eliminates graph a)

The right end of the whisker should be 29  (This eliminates graph b)

There are 7 points

The middle point is 4

The 4th point is 23

That is the line in the middle of the box  (This eliminates graph c)

The lower line of the box is at at point 2 = 17

The upper line of the box is at  point 6 = 28

This leaves us with graph D

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,
