Krisha has a chocolate Labrador retriever named Sam. She believes her dog weighs 60 pounds. Sam’s actual weight is 75 pounds. Find the percent error. (1 point)
$$
\text{Percent Error} = \left|\frac{\text{Observed Value} - \text{Actual Value}}{\text{Actual Value}}\right| \times 100
$$
Plugging in the values we have:
$$
\text{Percent Error} = \left|\frac{60 - 75}{75}\right| \times 100 = \left|\frac{-15}{75}\right| \times 100 = \frac{15}{75} \times 100 = 20
$$
So the percent error is 20%.
To find the percent error, you need to calculate the difference between the estimated weight and the actual weight, divide it by the actual weight, and multiply by 100. Here is the formula:
Percent Error = ((Actual Value - Estimated Value) / Actual Value) x 100
In this case, the estimated weight is 60 pounds, and the actual weight is 75 pounds. Plugging in these values into the formula, we can find the percent error:
Percent Error = ((75 - 60) / 75) x 100
First, subtract 60 from 75:
Percent Error = (15 / 75) x 100
Next, divide 15 by 75:
Percent Error = 0.2 x 100
Finally, multiply 0.2 by 100:
Percent Error = 20
Therefore, the percent error is 20%.
To find the percent error, we need to compare the difference between the estimated weight and the actual weight with the actual weight, and then multiply by 100.
The formula for percent error is:
Percent Error = \left| \dfrac{{\text{{Estimated Value}} - \text{{Actual Value}}}}{{\text{{Actual Value}}}} \right| \times 100
Given that Krisha estimated Sam's weight to be 60 pounds, and the actual weight is 75 pounds, we can substitute these values into the formula:
Percent Error = \left| \dfrac{{60 - 75}}{{75}} \right| \times 100
Simplifying further:
Percent Error = \left| -\dfrac{{15}}{{75}} \right| \times 100
Percent Error = \dfrac{{15}}{{75}} \times 100
Percent Error = \dfrac{{1}}{{5}} \times 100
Percent Error = 20
Therefore, the percent error is 20%.
