When you have the number 81 as your median and you have to find the missing number out of the following 82,87,77,70,80,88
Natali5045456 [20]
Uh, so, you're median is 81 already.

Since the middle two numbers are 82 and 80, you have to add them together and then divide by 2. 

However, if you're trying to add a number in, adding 81 as it is would work as well.

Hope this helps!

abruzzese [7]

Answer:

3.62

Step-by-step explanation:

I used a calculator. But on the bottom, it says the rounded number should only have 3 digits. The real answer is 3.622580645. But since I rounded the answer would be 3.62.

Hope this helps!
