Krisha has a chocolate Labrador retriever named Sam. She believes her dog weighs 55 pounds. Sam’s actual weight is 75 pounds. Find the percentage error. Round the answer to the nearest hundredth
To find the percentage error, we need to calculate the difference between the actual weight and the believed weight, divide that difference by the actual weight, and multiply by 100.
Difference = 75 - 55 = 20 pounds
Percentage Error = (20 / 75) * 100 = 26.67%
Rounded to the nearest hundredth, the percentage error is 26.67%.
To find the percentage error, we need to calculate the difference between Krisha's estimated weight and Sam's actual weight, and then express it as a percentage of Sam's actual weight.
Step 1: Calculate the difference between the estimated weight and the actual weight:
Difference = Actual weight - Estimated weight
Difference = 75 pounds - 55 pounds
Difference = 20 pounds
Step 2: Calculate the percentage error:
Percentage Error = (Difference / Actual weight) * 100
Percentage Error = (20 pounds / 75 pounds) * 100
To round the answer to the nearest hundredth:
Percentage Error ≈ 26.67%
To find the percentage error, we first need to determine the absolute difference between the believed weight and the actual weight. Then we calculate the percentage of this difference relative to the actual weight.
Step 1: Calculate the absolute difference between the believed weight and the actual weight:
Absolute difference = |believed weight - actual weight|
Absolute difference = |55 - 75|
Absolute difference = 20
Step 2: Calculate the percentage error relative to the actual weight:
Percentage error = (Absolute difference / actual weight) * 100
Percentage error = (20 / 75) * 100
Percentage error = 26.67
Rounding the answer to the nearest hundredth, the percentage error is approximately 26.67%.
