Answer:
3
Step-by-step explanation:
3÷2= 1.5
3÷5= 0.60
9÷10= 0.90
1.5+0.60+0.90= 3
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
Therefore, the missing value is 38.
