David measures a line to be 10.08 in long. If the actual measurement is 10in, find David's relative error to the nearest hundredth. Answer:

Understand relative error: Understand the concept of relative error. Relative error is the absolute error divided by the actual measurement, often expressed as a percentage. The absolute error is the difference between the measured value and the actual value.Calculate absolute error: Calculate the absolute error. Absolute error = |Measured Value - Actual Value| Absolute error = |10.08 in - 10 in| Absolute error = |0.08 in| Absolute error = 0.08 inCalculate relative error: Calculate the relative error. Relative error = (Absolute error / Actual Value) * 100 (to get the percentage) Relative error = (0.08 in / 10 in) * 100 Relative error = 0.008 * 100 Relative error = 0.8%Round relative error: Round the relative error to the nearest hundredth. Since the relative error is already at the hundredth place as 0.8%, we do not need to round it further.

Answer:

Understand relative error: Understand the concept of relative error. Relative error is the absolute error divided by the actual measurement, often expressed as a percentage. The absolute error is the difference between the measured value and the actual value.
Calculate absolute error: Calculate the absolute error. $\newline$ Absolute error = $|\text{Measured Value} - \text{Actual Value}|$ $\newline$ Absolute error = $|10.08 \text{ in} - 10 \text{ in}|$ $\newline$ Absolute error = $|0.08 \text{ in}|$ $\newline$ Absolute error = $0.08 \text{ in}$
Calculate relative error: Calculate the relative error. $\newline$ Relative error = $(\text{Absolute error} / \text{Actual Value}) \times 100$ (to get the percentage) $\newline$ Relative error = $(0.08 \, \text{in} / 10 \, \text{in}) \times 100$ $\newline$ Relative error = $0.008 \times 100$ $\newline$ Relative error = $0.8\%$
Round relative error: Round the relative error to the nearest hundredth. $\newline$ Since the relative error is already at the hundredth place as $0.8\%$ , we do not need to round it further.
