A measurement is given. Find the minimum and maximum possible measurements.
A bag of apples weighs 4 lbs to the nearest lb.
To find : the maximum and minimum possible measurements .
Answer to Problem 17P
Minimum measurement =3.5 lb and maximum measurement =4.5 lb
Explanation of Solution
Given information: A bag of apples weighs 4 lbs to the nearest lb.
Calculation:
The degree of accuracy is half a unit of measure.
The measurement was made to the nearest lb , so the greatest possible error is half of 1 lb, that is 0.5 lb.
Therefore,
Minimum measurement=(4-0.5) lb =3.5lb
Maximum measurement=(4+0.5) lb =4.5 lb
