What is the mode of the following data values
87, 39, 31, 52, 31

The mode of a set of data is the number that appears the most. We'll set it up from least to greatest to figure this out efficiently.
31, 31, 39, 52, 87.
31 appeared more than any other number, so 31 is the mode.

Option D.

Step-by-step explanation:

The slope of a horizontal line is 0.

It is given that the function 1 is a horizontal line that passing through the y-axis at y = 4.

It means the rate of change of function 1 is 0.

The slope intercept form of a linear function is

            (1)

where, m is slope and b is y-intercept.

The function 2 is

          (2)

On comparing (1) and (2), we get

The rate of change of function 2 is 8.

The difference between rate of change is

The rate of change of function 2 is 8 more than the rate of change of function 1.

Therefore, the correct option is D.
