Q. What is the greatest possible error for a measurement of 2 feet?
Determine precision: Determine the precision of the measurement.The measurement of 2 feet is precise to the ones place since there are no decimal places or fractions indicated.Precision: 1 foot
Calculate greatest possible error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the unit of precision. Since the precision is 1 foot, the greatest possible error is half of that.Greatest possible error = Precision/2Greatest possible error = 1 foot /2Greatest possible error = 0.5 feet
