Answer 2

order the numbers from least to greatest
if there's one number in the middle, that's your median
if there are 2, you take their average

for example the median in
1, 2, 4, 6, 10 is 4

but the median in
10 15 20 30 45 55 is 20+30/2=25

Answer 3

A?

Answer 4

The median is 42.5

Answer 5

40+45/2=85/2=42.5

Answer 6

You put them all in order including the 45 and you have two middle numbers (40,45) then you add them together and divide by 2 and you get 42.5

Answer 7

thank you both!
