Final answer:
Precision and accuracy are essential in mathematical measurements. A clock that is ten minutes fast may be precise but not accurate.
Explanation:
Precision and accuracy are two key concepts in mathematical measurements. Precision refers to the consistency of values obtained from repeated measurements, while accuracy indicates how close a measurement is to its true value. In the context of the clock question, a clock that is set ten minutes fast is precise (consistent in being fast by the same amount) but not accurate (not showing the correct time).
