Question

Joshua tells his friends that for there to be snow it has to be 32o F. He uses his thermometer outside and sees snow. He finds it is only is 34oF. What is his percent error? (Round to the nearest tenth)

Answer 1

To find the percent error, calculate the absolute error by subtracting the actual value from the measured value. Then, divide the absolute error by the actual value and multiply by 100 to get the percent error. In this case, the percent error is 6.3% (rounded to the nearest tenth).

Step-by-step explanation:

To find the percent error, we need to calculate the absolute error and divide it by the actual value, then multiply by 100. In this case, the actual value is 32°F and the measured value is 34°F.

Absolute error = |actual value - measured value| = |32 - 34| = 2°F

Percent error = (absolute error / actual value) * 100 = (2 / 32) * 100 = 6.25%

Therefore, Joshua's percent error is 6.3% (rounded to the nearest tenth).
