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.
To find the percent error, we use the formula:
Percent error = (|Actual value - Estimated value| / Actual value) * 100
In this case, the actual weight of Sam is 75 pounds, and Krisha estimated the weight to be 60 pounds.
Plugging in these values, we get:
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, you can use the following formula:
Percent Error = ( | Observed Value - Actual Value | / Actual Value ) x 100
In this case, the observed value is 60 pounds and the actual value is 75 pounds. Plugging these values into the formula:
Percent Error = ( | 60 - 75 | / 75 ) x 100
= ( | -15 | / 75 ) x 100
= ( 15 / 75 ) x 100
= 0.2 x 100
= 20%
Therefore, the percent error is 20%.
To find the percent error, you need to know the actual value and the estimated value. In this case, the actual weight of Sam is 75 pounds, and Krisha's estimate is 60 pounds.
The formula to calculate percent error is:
Percent Error = (|actual value - estimated value| / actual value) * 100
Let's plug in the values:
Percent Error = (|75 - 60| / 75) * 100
Calculating within the absolute value:
Percent Error = (15 / 75) * 100
Simplifying the fraction:
Percent Error = (1/5) * 100
Multiplying the fraction by 100:
Percent Error = 20
So the percent error is 20%. This means that Krisha's estimate of Sam's weight is 20% lower than his actual weight.
