The weight of a rock sample is measured to be 2.5 pounds. What is the percent of error in the measurement?
The weight of a rock sample is measured to be 2.5 pounds
To calculate the percent of error in the measurement, you need the actual value and the measured value. In this case, the actual weight of the rock sample is not given. Without the actual value, we cannot accurately determine the percent of error.
To find the percent of error in a measurement, we need to compare it to the accepted or true value.
In this case, let's assume the accepted or true weight of the rock sample is 2 pounds. The percent of error can be calculated using the formula:
Percent of Error = ((Measured Value - True Value) / True Value) * 100
Given:
Measured Value = 2.5 pounds
True Value = 2 pounds
Applying the values in the formula, we can find the percent of error:
Percent of Error = ((2.5 - 2) / 2) * 100
Percent of Error = (0.5 / 2) * 100
Percent of Error = 0.25 * 100
Percent of Error = 25%
Therefore, the percent of error in the measurement of the rock sample is 25%.
