Question

the actual weight of a bag of rice is 30 ounces, but the listed weight is 21 ounces. what percent is the measurement error of the actual weight? start by labeling the double number line to help you find the percent error. first, identify what represents the whole, or 100%, in this problem. ounces 0 % 100%

Explanation:

Step1: Calculate absolute error

$\text{Absolute Error} = |30 - 21| = 9$ ounces

Step2: Calculate percent error

$\text{Percent Error} = \frac{\text{Absolute Error}}{\text{Actual Value}} \times 100\% = \frac{9}{30} \times 100\%$

Step3: Simplify the expression

$\frac{9}{30} \times 100\% = 0.3 \times 100\% = 30\%$

Answer:

30%
