Jocelyn estimates that a piece of wood measures 5.5 cm. If it actually measures 5.62 cm, what is the percent error of Jocelyn’s estimate?
To calculate the percent error, we first need to find the difference between the estimated and actual measurements:
Actual measurement: 5.62 cm
Estimated measurement: 5.5 cm
Difference = Actual - Estimated
Difference = 5.62 cm - 5.5 cm
Difference = 0.12 cm
Next, we need to calculate the percent error using the formula:
Percent Error = (|Error| / Actual) x 100
Substitute the values into the formula:
Percent Error = (|0.12| / 5.62) x 100
Percent Error = (0.12 / 5.62) x 100
Percent Error = 0.0213 x 100
Percent Error = 2.13%
Therefore, the percent error of Jocelyn's estimate is 2.13%.
