Derrik thinks his dog weighs 60 pounds. It actually weights 75 pounds. Find the percent error.
To find the percent error, you can use the formula:
Percent Error = (|Actual Value - Estimated Value| / Actual Value) * 100%
In this case, the actual value is 75 pounds and the estimated value is 60 pounds.
Percent Error = (|75 - 60| / 75) * 100%
Percent Error = (15 / 75) * 100%
Percent Error = (0.2) * 100%
Percent Error = 20%
Therefore, the percent error is 20%.
To find the percent error, we will use the following formula:
Percent error = (|Exact value - Approximate value| / Exact value) x 100
In this case, the exact weight of the dog is 75 pounds, and Derrik thought it weighed 60 pounds.
Using the formula, we have:
Percent error = (|75 - 60| / 75) x 100
= (15 / 75) x 100
= 0.2 x 100
= 20%
Therefore, the percent error is 20%.
To find the percent error, we need to calculate the difference between the estimated weight (60 pounds) and the actual weight (75 pounds), and then express it as a percentage of the actual weight.
The formula for percent error is:
Percent Error = [(|Estimated Value - Actual Value|) / Actual Value] x 100
Substituting the given values into the formula, we have:
Percent Error = [(|60 - 75|) / 75] x 100
Percent Error = [(|-15|) / 75] x 100
Percent Error = [15 / 75] x 100
Percent Error = 0.2 x 100
Percent Error = 20%
Therefore, the percent error is 20%.
