Answer:
y = 541
Step-by-step explanation:
The mean is calculated as
mean =
Mean of set A = = = 266
ratio between means = 7 : 12, then
mean of set B = × 266 = 456 , thus
= 456 ( multiply both sides by 5 )
1739 + y = 2280 ( subtract 1739 from both sides )
y = 541
Answer:
Average rate of change for the number of African American women who held office at any given time between 1970 & 1993 is <u> 94.43.</u>
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.
First of all, the angle bisector, angle ray and angle line are all lines. Please refer to the picture attached. All of these lines are joined at one point called vertex which is at point O. The angle bisector is the line that divides the total angle into half. In this case, that would be line OB. The angle ray and line are the two legs of the angle, which are line OA and line OC, respectively.
All the answers, which are reduced to lowest terms, and the steps are in the images below (they’re in order based on the questions). I only answered questions <em>a</em> through <em>e </em>(not f), because it would only allow me to attach five photos. The answer for question <em>c</em> is in mixed numbers form because image said , so as an improper fraction it’s .
Hope this helps my friend! :)
