(prob going to copy and paste this to a few other questions so more of ya'll can see it :D)
To find the percent error in Aatikah's prediction, we can use the formula:
Percent Error = ((Predicted Value - Actual Value) / Actual Value) * 100
In this case, the predicted value is $30.00 and the actual value is $19.75.
Substituting these values into the formula:
Percent Error = ((30.00 - 19.75) / 19.75) * 100
Calculating the difference:
Percent Error = (10.25 / 19.75) * 100
Simplifying:
Percent Error = 0.518987 * 100
Percent Error = 51.8987
Rounding to the nearest whole number, the percent error is 52%.
To find the percent error in Aatikah's prediction, we need to calculate the absolute difference between her predicted amount ($30) and the actual amount she spent ($19.75), and then divide it by her predicted amount, and multiply by 100.
The absolute difference is: $30 - $19.75 = $10.25
The percent error is: (10.25 / 30) * 100 ≈ 34.2%
Rounding to the nearest whole number, the percent error is 34%.
To find the percent error, use the formula:
Percent Error = (|Observed Value - Predicted Value| / Predicted Value) x 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) x 100
Percent Error = (|-10.25| / 30.00) x 100
Percent Error = (10.25 / 30.00) x 100
Percent Error ≈ 0.34 x 100
Percent Error ≈ 34%
Therefore, the closest whole number percent error is 34%.
