It was known that the actual length of the beam was 6.3 in. The class was asked to measure the beam using different types of measuring tapes. Demetrius's tape was accurate to one-eighth of an inch, so he measured the board to be 6.25 in. What was the experimental error of the measurement? Do not round. a. –0.5 in.
b. –0.05 in.
c. 0.05 in.
d. 0.5 in.
