Some one help me with my math homework?!?
I'm looking for assistance with my math homework. The median of the given set of six ordered data values is 31.5. The values are 7, 12, 25, __, 41, and 51. Can someone help me find the missing value? Thank you!

38
Since the middle numbers are 25 and 38, you need to find the number exactly in the middle of both of them to find the median,
step 1:
x=the missing value
the median is the middle number, but in this case there are two which happens to be 25 and x
so the formula is
25+x/2=31.5
use algebra to solve
25+x=63
x=63-25
x= 38
the missing value is 38
the missing value is 38 because you take the median which is the 2 middle numbers added together then divided by 2. so to reverse it to find the answer you take 31.5 *2 and it come out as 63.
now we subtract 25 from 63 like 63-25 = 38. 38 is your answer.
