Final answer:
To find John's percent error, we can use the formula: Percent Error = |(measured value - actual value) / actual value| × 100. Given that John measured the blanket as 6 feet, and the actual measurement was 5.5 feet, the percent error is 9.0909%.
Step-by-step explanation:
To find John's percent error, we can use the formula:
Percent Error = |(measured value - actual value) / actual value| × 100
Given that John measured the blanket as 6 feet, and the actual measurement was 5.5 feet, we can plug in these values into the formula:
Percent Error = |(6 - 5.5) / 5.5| × 100
Calculating this expression, we get:
Percent Error = |0.5 / 5.5| × 100
Simplifying further, we have:
Percent Error = 0.090909 × 100
Finally, calculating the product, we find that:
Percent Error = 9.0909%
