In 1970 there were 160 African American women in elected public office in the United States. By 1993 the number had increased to
timama [110]

Answer:

Average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is   94.43.

Step-by-step explanation:

Here, according to the question:

Number of African American women in elected public office in the United States in the year 1970 = 160

Number of African American women in elected public office in the United States in the year 1993 = 2332

Now, the change in the number of elected women between 1970 & 1993

= Women elected in the year 1993 - Women elected in the year 1970

=  2332 -  160  = 2,172

or, the change in the number of elected women candidates between 1970 & 1993 is 2,172

Now, the difference in the time period is 1993 - 1970 =  23 years

So, \textrm{The average rate of change}  = \frac{\textrm{Total change in the quantity}}{\textrm{Time Interval}} \\=\frac{2172}{23}  = 94.43

Hence, the average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is 94.43.
