Question

A student has a container with a volume of 2.5 liters. She estimates the volume to be 2.7 liters. By what percent is the​ student's estimate​ off?

Answer 1

To determine the percent by which the student's estimate is off, we need to find the difference between the actual volume and the estimated volume, and then divide it by the actual volume. The student's estimate is off by 8%.

Step-by-step explanation:

To determine the percent by which the student’s estimate is off, we need to find the difference between the actual volume and the estimated volume, and then divide it by the actual volume.

Difference = Actual volume - Estimated volume = 2.5 L - 2.7 L = -0.2 L
Percent error = (Difference / Actual volume) x 100% = (-0.2 L / 2.5 L) x 100% = -8%.

Therefore, the student’s estimate is off by 8%.
