Question

A. 0.2 inch.

B. 0.5 inch.

C. 0.3 inch.

D. 0.4 inch.

Answer 1

(D) . The best estimate of the total rainfall is 0.4 inches.

Explanation:

Here, as given in the data:

The rainfall on the first day = 0.13 inches

Now, the 'nearest tenth' estimation of 0.13 = 0.10 as ( 3 < 5)

So, the estimated rainfall on first day = 0.10 inches

The rainfall on the second day = 0.08 inches

Now, the 'nearest tenth' estimation of 0.08 = 0.10 as ( 8 > 5)

So, the estimated rainfall on second day = 0.10 inches

The rainfall on the third day = 0.18 inches

Now, the 'nearest tenth' estimation of 0.18 = 0.20 as ( 8 > 5)

So, the estimated rainfall on third day =0.20 inches

So, total estimated rainfall = Estimated rainfall on ( first + second + third day)

= 0.10 inches + 0.10 inches + 0.20 inches

= 0.40 inches

Hence, the best estimate of the total rainfall is 0.4 inches.
