Question

in an investigation on accuracy and precision, myriah measures the mass of a 10.00 g piece of metal several times. her measurements are 9.98 g, 10.02 g, 10.01 g, and 9.99 g. which statement best describes her results? they are both precise and accurate they are neither accurate nor precise they are precise but not accurate they are accurate but not precise

Explanation:

Accuracy refers to how close a measurement is to the true - value. The true mass of the metal is 10.00 g, and the measurements 9.98 g, 10.02 g, 10.01 g, and 9.99 g are close to 10.00 g. Precision refers to how close the measurements are to each other. The values 9.98 g, 10.02 g, 10.01 g, and 9.99 g are also close to each other.

Answer:

They are both precise and accurate
