Question

A. 66 inches
B. 2 inches
C. 2 percent
D. 68 inches

Answer 1

Answer: 2 inches

Step-by-step explanation: The absolute error of Marc's measurement is 2 inches.

Absolute error is the absolute value of the difference between the measured value and the actual value. In this case, Marc measured the height of the sunflower plant as 66 inches, but the actual height is 68 inches.

To calculate the absolute error, we subtract the measured value from the actual value and take the absolute value of the result: |68 - 66| = 2 inches.

Therefore, the absolute error of Marc's measurement is 2 inches.
