Answer: 114%
Step-by-step explanation:
The formula to calculate percent error is :-
[tex]\text{Percent error}=\frac{|\text{predicted-actual}|}{\text{actual}}\times100[/tex]
Given: The predicted value =122
The actual value =57
Substitute the values in the above formula ,we get
[tex]\text{Percent error}=\frac{|122-57|}{57}\times100\\\\=\frac{65}{57}\times100\\\\=1.14035087719\times100\\\\=114.035087719\%\approx114.0\%[/tex]
