Question

Laura estimated the volume of her be 31 gal. The actual volume of her bathtub was 35 gal. Find the absolute error and the percent error of Laura's estimate. If necessary, round your answers to the nearest tenth.​

What is the absolute error in Laura's volume estimation?
A. 3 gallons
B. 4 gallons
C. 5 gallons
D. 6 gallons

Answer 1

The absolute error in Laura's volume estimation is 4 gallons, and the percent error is approximately 11.4%.

Step-by-step explanation:

The absolute error in Laura's volume estimation is the absolute difference between her estimate and the actual volume. In this case, the absolute error is calculated by subtracting Laura's estimate of 31 gallons from the actual volume of 35 gallons, resulting in an absolute error of 4 gallons.

To find the percent error, we divide the absolute error by the actual volume and multiply by 100. So, the percent error is calculated as (4 gallons / 35 gallons) * 100, which is approximately 11.4%.
