use the graph to estimate the average rate of change of the percentage of new employees from 1994 to 2000, from 2000 to 2006, and from 1994 to 2006. what is the average rate of change of the percentage of new employees from 1994 to 2000? % per year (type an integer or a decimal rounded to two decimal places as needed.) what is the average rate of change of the percentage of new employees from 2000 to 2006? % per year (type an integer or a decimal rounded to two decimal places as needed.) what is the average rate of change of the percentage of new employees from 1994 to 2006? % per year (type an integer or a decimal rounded to two decimal places as needed.)
Answer
Explanation:
Step1: Recall average rate - of - change formula
The average rate of change formula is $\frac{f(b)-f(a)}{b - a}$, where $a$ and $b$ are the starting and ending years, and $f(a)$ and $f(b)$ are the corresponding percentage values of new employees.
Step2: Estimate values for 1994 - 2000
Let's assume from the graph that the percentage of new employees in 1994 ($a = 1994$), $f(1994)\approx5$ and in 2000 ($b = 2000$), $f(2000)\approx18$. Then the average rate of change from 1994 to 2000 is $\frac{f(2000)-f(1994)}{2000 - 1994}=\frac{18 - 5}{6}=\frac{13}{6}\approx2.17$.
Step3: Estimate values for 2000 - 2006
Assume that in 2000 ($a = 2000$), $f(2000)\approx18$ and in 2006 ($b = 2006$), $f(2006)\approx16$. Then the average rate of change from 2000 to 2006 is $\frac{f(2006)-f(2000)}{2006 - 2000}=\frac{16 - 18}{6}=-\frac{2}{6}\approx - 0.33$.
Step4: Estimate values for 1994 - 2006
Assume that in 1994 ($a = 1994$), $f(1994)\approx5$ and in 2006 ($b = 2006$), $f(2006)\approx16$. Then the average rate of change from 1994 to 2006 is $\frac{f(2006)-f(1994)}{2006 - 1994}=\frac{16 - 5}{12}=\frac{11}{12}\approx0.92$.
