Answer: 7,500 passengers
Step-by-step explanation: Let's put the numbers from least to greatest...
5,000, 6,000, (7,000, 8,000,) 9,000, 10,000
Since there is an even number of numbers we will have two medians for the time being...
7,000 + 8,000 = 15,000
15,000 ÷ 2 = 7,500
Therefore, the median is 7,500, there are 7,500 passengers in total.
I hope this helps!
