Alex measures a line to be 6.43cm long. If the actual measurement is 6cm, find Alex's relative error to the nearest hundredth. Answer:

Calculate Absolute Error: To find the relative error, we need to calculate the absolute error and then divide it by the actual measurement. The absolute error is the difference between the measured value and the actual value. Calculation: Absolute error = |Measured value - Actual value| = |6.43cm - 6cm| = 0.43cmCalculate Relative Error: Now we need to calculate the relative error by dividing the absolute error by the actual measurement. Calculation: Relative error = Absolute error / Actual value = 0.43cm / 6cmPerform Division: Perform the division to find the relative error. Calculation: Relative error = 0.43cm / 6cm ≈ 0.071666...Round to Nearest Hundredth: To express the relative error to the nearest hundredth, we round the result to two decimal places. Calculation: Relative error ≈ 0.07 (to the nearest hundredth)

6.43 \mathrm{~cm}

long. If the actual measurement is

6 \mathrm{~cm}

, find Alex's relative error to the nearest hundredth.

Answer:

Calculate Absolute Error: To find the relative error, we need to calculate the absolute error and then divide it by the actual measurement. The absolute error is the difference between the measured value and the actual value. $\newline$ Calculation: Absolute error = $|\text{Measured value} - \text{Actual value}| = |6.43\,\text{cm} - 6\,\text{cm}| = 0.43\,\text{cm}$
Calculate Relative Error: Now we need to calculate the relative error by dividing the absolute error by the actual measurement. $\newline$ Calculation: Relative error = $\frac{\text{Absolute error}}{\text{Actual value}} = \frac{0.43\,\text{cm}}{6\,\text{cm}}$
Perform Division: Perform the division to find the relative error. $\newline$ Calculation: Relative error = $\frac{0.43\,\text{cm}}{6\,\text{cm}} \approx 0.071666...$
Round to Nearest Hundredth: To express the relative error to the nearest hundredth, we round the result to two decimal places. $\newline$ Calculation: Relative error $\approx 0.07$ (to the nearest hundredth)
