Question

To be labeled as a jumbo egg, the egg is supposed to weigh 2.5 oz. Priya buys a carton of jumbo eggs as 2.4 oz. what is the percentage error?

Answer 1

4%

Step-by-step explanation

We want to find the perecntage error in the given situation.

Percentage error is given as:

`\text{ \%error = }(|x_2-x_1|)/(x_1)\cdot\text{ 100}`

where:

x1 = expected value of weight

x2 = measured value of weight

The numerator represents the absolute value of the difference between the two weights.

Therefore, the percentage error is:

`\begin{gathered} \text{ \%error = }\frac{|2.4\text{ - 2.5}|}{2.5}\cdot\text{ 100 = }(|-0.1|)/(2.5)\cdot\text{ 100} \\ \text{ \%error = }(0.1)/(2.5)\cdot\text{ 100 = 0.04 }\cdot\text{ 100} \\ \text{ \%error = 4\%} \end{gathered}`

The percentage error is 4%.
