Given:
Estimated weight of a cat = 16 pounds
Actual weight of that cat = 14.25 pounds
To find:
The percent error to the nearest tenth of a percent.
Solution:
We know that,
![\text{Percent error}=\frac{\text{Estimated value - Actual value}}{\text{Actual value}}* 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/8cge71ziacrzumm6itwt4h9h5p5uplz1ou.png)
Using the above formula, we get
![\text{Percent error}=(16-14.25)/(14.25)* 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/x2sbaqp2j7ockpqajwfz6wlzlxwc6ml71s.png)
![\text{Percent error}=(1.75)/(14.25)* 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/wfoesc2wsozgvo0nzgp5k88yqb4ynmsw3z.png)
![\text{Percent error}=0.122807* 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/hlh5259ekt5wpy18vqyf4d8hcixrqy8tze.png)
![\text{Percent error}=12.2807](https://img.qammunity.org/2021/formulas/mathematics/high-school/fbf9incvkw2hb5da44kjct8rwr89gcvf4a.png)
Round the percent error to the nearest tenth of a percent.
![\text{Percent error}\approx 12.3](https://img.qammunity.org/2021/formulas/mathematics/high-school/e1ordukl7quqiz6z83riz8er9y3shvvufh.png)
Therefore, the percent error is 12.3%.
