Answer:
Step-by-step explanation:
since the data is already arranged in ascending to descending u don't have to change.
upper quartile (Q3) = 3(n + 1)/4 (n means no of data)
=3(10 + 1)/4
=3*11/4
=33/4
=8.25
=8 th term + 0.25(9 th term - 8 th term)
=11 + 0.25(13 - 11)
=11 + 0.25*2
=11 + 0.5
=11.5
Line B is traveling faster. I know this because Line B has a steeper line than line A.
27+3x-31=20
-4+3x=20
+4 +4
3x=24
X=8
