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. (1 point)
$$
To find the percent error, we use the formula:
Percent Error = (|Expected Value - Actual Value| / Actual Value) * 100
In this case, the expected value is 60 pounds and the actual value is 75 pounds.
Using the formula, we have:
Percent Error = (|60 - 75| / 75) * 100
= (15 / 75) * 100
= 0.2 * 100
= 20%
Therefore, the percent error is 20%.
To find the percent error, you need to compare the difference between the observed value (Krisha's belief) and the actual value of Sam's weight, and express it as a percentage of the actual value.
First, calculate the difference between the observed value and the actual value:
Difference = Actual Value - Observed Value
Difference = 75 pounds - 60 pounds
Difference = 15 pounds
Next, calculate the percent error:
Percent Error = (Difference / Actual Value) * 100
Percent Error = (15 pounds / 75 pounds) * 100
Percent Error = 0.2 * 100
Percent Error = 20
Therefore, the percent error is 20%.
