Question

A length of wood has a labeled length value of 2.50 meters. You measure its length three times. Each time you get the same value: 2.35 meters. What is the percent error of your measurements? *

Answer 1

6%

Step-by-step explanation:

Actual length of the wood is 2.5 m

Observed length of the wood is 2.35 m

We need to find the percent error of your measurements. The formula of the percentage error is given by :

`\%=\frac{|\text{observed-actual}|}{\text{actual}}* 100\\\\\%=(2.5-2.35)/(2.5)* 100\\\\\%=6\%`

Hence, the percentage error is 6%.
