Answer:
Absolute error = 39
Percent Error = 6.10%
Step-by-step explanation:
Actual value = 639 pounds
Observed Value = 600 pounds
The formula to find absolute error is:
Absolute Error = Actual value - Observed Value
= 639 - 600
= 39
The formula to find Percent error is:
Percent Error = (Actual value - Observed Value / Actual value)*100
= (639 - 600/639)*100
= 6.10%
<u>Answer:</u>
Absolute error = 39 pounds
Percent error = 6.10%
<u>Step-by-step explanation:</u>
We know that the estimated weight was 600 pounds while the actual weight of the beam was 639 pounds.
So we will find their difference to get the absolute error.
Absolute error = 639 - 600 = 39 pounds
We will use the following formula to find the percent error.
<em>Percent error = (Estimated value - actual value / actual value) * 100</em>
Percent error = 639 - 600 / 600 * 100 = 6.10%
