To find the percent error, we need to calculate the difference between the predicted amount and the actual amount, divide it by the predicted amount, and then multiply by 100 to find the percentage.
Difference = $30.00 - $19.75 = $10.25
Percent Error = (10.25/30.00) * 100
Now, we can calculate the percentage:
Percent Error = (0.3416666666666667) * 100
Percent Error ≈ 34.17
Rounded to the nearest whole number, the percent error is 34%.
To find the percent error in Aatikah's prediction, we need to compare her predicted amount of $30.00 to the actual amount she spent, which is $19.75.
The formula for percent error is:
Percent Error = (|Observed Value - Predicted Value| / |Predicted Value|) * 100
Substituting the values:
Percent Error = (|19.75 - 30.00| / |30.00|) * 100
Calculating:
Percent Error = (10.25 / 30.00) * 100
Percent Error = 0.3416 * 100
Percent Error = 34.16
Rounding to the nearest whole number, the percent error is 34%.
Therefore, the correct answer is:
• 34%
To find the percent error, we can use the following formula:
Percent Error = |(Observed Value - Predicted Value) / Predicted Value| * 100
In this case, the observed value is $19.75 and the predicted value is $30.00.
Percent Error = |($19.75 - $30.00) / $30.00| * 100
Percent Error = |- $10.25 / $30.00| * 100
Percent Error = |0.34166| * 100
Percent Error ≈ 34.166
Rounding the answer to the nearest whole number, the percent error is 34%.
Therefore, the correct answer is 0 34%.
