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
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
= (|-15| / 75) * 100
= (15 / 75) * 100
= 0.2 * 100
= 20%
Therefore, the percent error is 20%.
how did you get 100
Apologies for the confusion. The value 100 in the calculation represents the conversion from a decimal to a percentage.
To calculate the percent error, you divide the absolute difference between the measured value and the actual value by the actual value. Then, you multiply the result by 100 to express it as a percentage. In this case, the formula is:
Percent error = (|measured value - actual value| / actual value) * 100
Using the values given, the calculation is as follows:
Percent error = (|60 - 75| / 75) * 100
= (|-15| / 75) * 100
= 15 / 75 * 100
= 0.2 * 100
= 20%
Therefore, the percent error is 20%.
