Q. What is the percent error for a measurement of 25 metric tons?If needed, round your answer to the nearest hundredth of a percent.____%
Find Error: Find the greatest possible error for 25 metric tons.Divide the smallest unit of measurement by 2.Since the problem does not specify the smallest unit of measurement for metric tons, we will assume it is 0.01 metric ton (which is a common precision for large measurements like metric tons).0.01/2=0.005Greatest possible error: 0.005 metric tons
Divide by Half: Calculate the percent error.We have: Measurement: 25 metric tons Greatest possible error: 0.005 metric tons Percent error = (Greatest possible error/Measurement)×100%Percent error = (0.005/25)×100%= 0.0002×100%= 0.02%
