Question

1. a set of 500 - g masses is placed one at a time on a digital balance during quality control testing. the mass reading are 397 g, 401g, 403 g. describe the accuracy and precision of the scale. (1 point)

precise but not accurate
accurate but not precise
both accurate and precise
not accurate and not precise.

Explanation:

Accuracy refers to how close a measurement is to the true value. Here the true value is 500 - g, and the measured values (397 g, 401 g, 403 g) are far from it, so it's not accurate. Precision is about how close repeated measurements are to each other. The measured values are close to each other, so it's precise.

Answer:

Precise but not accurate
