9465 people/square mile.
Step-by-step explanation:
If there are 646,449 people in 68.3 square miles for the district of columbia, the unit rate in terms of people per square mile for the District of Columbia will be expressed as shown;
646,449 people = 68.3 square miles
x people = 1 square mile
Cross multiply
646,449 people * 1 square mile = 68.3 square miles * x people
x = 646,449 people * 1 square mile/68.3 square miles
x = 646,449/68.3 square miles
x = 9464.8463 square miles
x ≈ 9465 people/square mile.

If a higher number is added, the median will be the average of the last two 17s. In other words, there is no number that can be added that will change the median from 17.
Any value can be added without changing the median.
