Question 4 = Option A
Since the volume is given as 630 inch^3, you need to work out the dimensions by multiplying and check which option gives you the answer 630.
Only 7 x 9 x 10 gives you the answer 630.

Question 5 = Option B
6 cups are being divided into 8 friends.
6 divided by 8 comes out to be 3/4.

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
