Answer:
(D) . The best estimate of the total rainfall is 0.4 inches.
Step-by-step 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.
