jeka57 [31]

Answer:

x=7

y=8

Step-by-step explanation:

-Given that the mean and median is the same.

-Let b=mean =median

#Given that the set is arranged in order and is even:

median=\frac{n+1}{2}\\\\Median=3^{rd} \ term\\\\=x

Hence:

b=median=mean\\\\b=x\\\\\therefore mean=median=x

-Applying the mean formula:

\bar x=\frac{1}{n}\sum{x_i}\\\\\therefore 5x=4+6+x+y+10\\\\4x=20+y\\\\x=5+0.25y

#Since the number are in order:

6

Hence, x=7 and y=8
