four people weigh a standard mass of 10.00 g on the same balance. the first person obtains a reading of 12.00 g, the second person reads 9.14 g, the third person reads 10.33 g, and the fourth person reads 12.55 g. these readings suggest the balance is

precise

accurate

neither accurate nor precise

accurate and precise

Neither accurate nor precise.

Explanation:

Accuracy is defined as the degree of agreement between the result of a measurement and a true value of the measurand. In other words, it refers to how close the measurements of a measurement system are to the actual value.

Precision is defined as the degree of agreement between the independent results of a measurement, obtained under stipulated conditions. That is, precision refers to how close the measurements of a measurement system are to the true value.

Both are independent of each other.

The correc answer is "Neither accurate nor precise."

The individual measurements are not close to each other and are therefore not accurate. But y are close to the actual value (10 g) and are therefore not exact.
