Question

larry took his new puppy, belle, to the veterinarian. before the visit, larry guessed she weighed 9.5 pounds. during the visit, belle actually weighed 10 pounds. what is the percent error for larry’s guess? if necessary, round your answer to the nearest tenth of a percent.

Explanation:

Step1: Find the absolute error

The absolute error is the absolute value of the difference between the actual value and the guessed value. So, \( |10 - 9.5| = 0.5 \).

Step2: Calculate percent error

The formula for percent error is \( \text{Percent Error} = \frac{\text{Absolute Error}}{\text{Actual Value}} \times 100\% \). Substituting the values, we get \( \frac{0.5}{10} \times 100\% = 5.0\% \).

Answer:

5.0%
