Answer the question.Your true height is 70.4 inches. A tape measure that can be read to the nearest tenth of an inch gives your height as 70.5 inches. A second tape measure which can be read to the nearest eighth of an inch gives your height as 70
inches. Which of these two measurement is more precise? Which is more accurate?
A. The first tape measure gives a more precise reading but the second tape measure gives a more accurate reading. B. The second tape measure gives a more precise reading and also a more accurate reading. C. The second tape measure gives a more precise reading but the first tape measure gives a more accurate reading. D. The first tape measure gives a more precise reading and also a more accurate reading.
