Answer 2

The thickness of the pile is
`2(1)/(4) in.` or 2.25 inches thick

Explanation:

Here we have from the line plot, the four thinnest books given by;

Two books of 1/2 inch thickness and two books 5/8 inch thickness

Therefore when the two 1/2 inch thick books are piled on top of the to 5/8 inch thick books we have the total thickness of the pile given as follows;

`2* (1)/(2) in. + 2* (5)/(8) in.= (9)/(4) in. = 2(1)/(4) in.`

The thickness of the pile =
`2(1)/(4) in.`
