Question

which statement about the accuracy and precision of measuring tools is true? a. tools that are accurate cannot be precise. b. even if a tool is accurate, it is not necessarily precise. c. tools that are accurate are also precise. d. if a tool is not accurate, then it cannot be precise.

Explanation:

Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close repeated measurements are to each other. A tool can be accurate without being precise (e.g., measurements are close to the true - value but not close to each other).

Answer:

B. Even if a tool is accurate, it is not necessarily precise.
