Final answer:
The measurement of 10.9 inches is the most accurate because it is the closest to the reference value of 11.0 inches, reflecting the concept that accuracy is determined by closeness to a known correct value.
Step-by-step explanation:
To evaluate which of the measurements was most accurate, we would look for the measurement that is closest to the known reference value for that measurement. Considering the example of measuring the length of standard computer paper, we were provided with the measurements of 11.1 inches, 11.2 inches, and 10.9 inches, and the known reference length of the paper is 11.0 inches. The measurement of 10.9 inches is the most accurate because it is closest to the correct value of 11.0 inches. This demonstrates that the accuracy of a measurement is determined by how close it is to the accepted reference value.
