If you could speak to the African Americans who became congressmen after the Civil War, what would you say to them and why? In your opinion what was their impact on the United States?

Explanation:

I would say this:

It is incredible that through your state of alienation, you proceeded to follow your wantings in life. You as an apparent "unneeded member of society" to most, are no different from the rest of us. You are a human, and that is all that matters. You've impacted the Americas greatly and I thank you for that.

The African American congressmen at that time showed us that now in the present, no matter if you are looked significantly down upon, you can work your way up to the top of the government hierarchy.

the median of the data is 4.

step-by-step explanation:

the median means the middle number of a given number.

to decide which one is the median, arrange in ascending or descending order. but sometimes, you may find two(2) number in the middle, but it's easy, just add them together and divide by 2.

so,   determine the median of the data. 2, 3, 3, 4, 5, 7, 9

it is already arranged, count 3 times forward and 3 backward and the one left is your answer.

2,3,3,4,5,7,9

our answer is 4.

hope this !
