What is the average rate of change for the data from the 5th hour to the 8th hour? Be sure to include the correct units of measurement. A scatter plot with x axis labeled Hour and y axis labeled Money Earned in Dollars per Hour with points at 1 comma 54 and 2 comma 58 and 3 comma 64 and 4 comma 78 and 5 comma 96 and 6 comma 126 and 7 comma 99 and 8 comma 75 7 hours −7 dollars per hour per hour 21 dollars −21 dollars per hour per hour.

Answer 1

The average rate of change for the data from the 5th hour to the 8th hour is 8 dollars per hour.

Given

An ice cream truck sells ice cream between 2 p.m. and 10 p.m. each night in the summer.

At the end of the night, the driver calculates his profits and makes a graph to analyze the data.

How to find the average rate of change?

The formula is used to find the average rate of change is;

$\rm Average \ rate \ of \ change =\dfrac{x_2-x_1}{y_2-y_1}$

Here, $\rm x_1=54, \ x_2=78, \ y_1=1, \ y_2=4$

Substitute all the values in the formula

$\rm Average \ rate \ of \ change =\dfrac{x_2-x_1}{y_2-y_1}\\\\\rm Average \ rate \ of \ change =\dfrac{78-54}{4-1}\\\\\rm Average \ rate \ of \ change =\dfrac{24}{3}\\\\\rm Average \ rate \ of \ change =8 \ Doller \ per \ hour$

Hence, the average rate of change for the data from the 5th hour to the 8th hour is 8 dollars per hour.

Answer 2

Answer:

-7 a hour

Step-by-step explanation:

The average rate of change is the ratio of the change in the dependent variable (Money Earned) to the change in the independent variable (Hour).

Thus, the average rate of change for the data from the 5th hour to the 8th hour is calculated using the points (5, 96) and (8, 75) from the graph. This is, what happens in the middle does not affect the average rate of change.
