Question
In science class, Mr. Brodell’s students were directed to weigh a 400-gram mass on the balance scale. Erika weighed the object and reported 420 grams. What is the percent error of the weight of Erika's object?

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 420 grams and the actual value is 400 grams.
percent error = (|420 - 400| / 400) * 100
percent error = (20 / 400) * 100
percent error = 0.05 * 100
percent error = 5%
Therefore, the percent error of the weight of Erika's object is 5%.
percent error = (|measured value - actual value| / actual value) * 100
In this case, the measured value is 420 grams and the actual value is 400 grams.
percent error = (|420 - 400| / 400) * 100
percent error = (20 / 400) * 100
percent error = 0.05 * 100
percent error = 5%
Therefore, the percent error of the weight of Erika's object is 5%.
