Question

You estimate that the length of a piece of wood is 7 7/8 feet. The actual length is 8 feet find the percent error

Answer 1

12.5%

Explanation:

To find the percent error, you can use the formula:

Percent Error = (|Estimated Value - Actual Value| / Actual Value) * 100.

In this case, the estimated value is 7 7/8 feet (which is equivalent to 63/8 feet) and the actual value is 8 feet.

Let's calculate the percent error using the formula:

Percent Error = (|63/8 - 8| / 8) * 100.

Percent Error = (|63 - 64| / 8) * 100.

Percent Error = (1 / 8) * 100.

Percent Error = 12.5%.
