The percentage error can be calculated using a formula give as follows;
[tex]\begin{gathered} \delta=|\frac{\upsilon a-\upsilon e}{\upsilon e}|\times100 \\ \text{Where }\delta=percent\text{ error} \\ \upsilon a=actual\text{ value} \\ \upsilon e=\exp ected\text{ value} \\ \delta=|\frac{44.5-30}{30}|\times100 \\ \delta=|\frac{14.5}{30}|\times100 \\ \delta=0.4833\times100 \\ \delta=48.33 \\ \delta\approx48.3\text{ (to the nearest tenth)} \end{gathered}[/tex]The percentage error rounded to the nearest tenth equals 48.3%
