Answer:
The one that doesn't belong is the square root (the only irrational number in the list)
Step-by-step explanation:
The numbers;
50.1.....
50/2
and -50.1
are all rational numbers that can be written as a quotient of two integers.:
451/9 = 50.1111...
50/2
-501/10 = -50.1
The only one that cannot is the square root of 50 (it is an irrational number) since 50 is NOT a perfect square.
The median is 84.5. Feel free to ask me any other questions.
-4 or
Rise 4 and run 1 to the left (that's what makes it negative)
