Answer:
- -1/3
- not geometric
- -5
- 4
Step-by-step explanation:
You find the ratio of terms by dividing the second by the first. If the ratio is the same for all adjacent pairs of terms, it is a "common" ratio.
1) (2/3)/-2 = -1/3
(-2/9)/(2/3) = -1/3
(2/27)/(-2/9) = -1/3 . . . . . the common ratio is -1/3
___
2) 2/0 = undefined . . . . not a geometric sequence
___
3) -10/2 = -5
50/-10 = -5
-250/50 = -5 . . . . . the common ratio is -5
___
4) 4/1 = 4
16/4 = 4
64/16 = 4 . . . . . the common ratio is 4
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, 
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.
