Question

Krisha has a chocolate Labrador retriever named Sam. She believes her dog weighs 60 pounds. Sam’s actual weight is 75 pounds. Find the percent error.

a) 20%
b) 25%
c) 30%
d) 15%

Answer 1

The percent error between Krisha's estimated weight of her dog and the actual weight is 20%.

Step-by-step explanation:

The percent error can be calculated using the formula:

Percent Error = (|Measured Value - Actual Value| / Actual Value) × 100

In this case, the measured value is 60 pounds and the actual value is 75 pounds.

Percent Error = (|60 - 75| / 75) × 100 = 20%

Therefore, the correct answer is a) 20%.
