To calculate the percent error of a measurement, you need to know both the measured value and the accepted (true) value. The formula for percent error is:
\[ \text{Percent Error} = \left( \frac{|\text{True Value} - \text{Measured Value}|}{|\text{True Value}|} \right) \times 100 \]
In this case, we only have the measured value of the rope (13 m). If we assume that the true length of the rope is also 13 m (for simplicity), the error would be:
\[ \text{True Value} = 13,m \] \[ \text{Measured Value} = 13,m \] \[ \text{Percent Error} = \left( \frac{|13 - 13|}{|13|} \right) \times 100 = \left( \frac{0}{13} \right) \times 100 = 0% \]
However, if you are looking for the percent error based on an assumed true value (not provided), you would need to know that value to perform the calculation.
For the options provided (0.38%, 0.15%, 3.85%, 0.92%), without additional information on the true value or a context indicating that the measured value is not the expected value, we cannot accurately determine the percent error of the measurement.
If you'd like me to proceed with specific assumptions or scenarios, please provide additional details!
