Question

Emelia measures the weight of a rock to be 30 grams. The actual weight of the rock is 24 grams. Determine Emelia's percent error.

Answer 1

Answer: 25%

Explanation:

Given

Emelia measures the weight of the rock to be 30 gm

The actual weight was 24 gm

Percentage error is given by

`\Rightarrow \frac{\text{Deviation }}{\text{Actual value}}* 100`

Insert the values

`\Rightarrow (30-24)/(24)* 100\\\\\Rightarrow (6)/(24)* 100\\\\\Rightarrow 25\%`

Therefore, the percentage error is 25%.
