Answer:
The answer is B. 14.7%.
Step-by-step explanation:
Given:
Estimated time need to complete project [tex]17h[/tex].
Actually time needed [tex]19\frac{1}{2}h[/tex]=[tex]\frac{39}{2}[/tex]h.
Difference between the time [tex]ET-AT[/tex]= [tex]\frac{39}{2}- 17\\=\frac{39}{2} -\frac{34}{2}\\ =\frac{5}{2}[/tex][tex]=2.5h[/tex].
So, the percentage error is [tex]\frac{2.5}{17}\times100\\ =\frac{250}{17} \\=14.70%[/tex].
Therefore, the answer is B. 14.7%.
Answer:
Option (A)
Anson percent error is 12.8%
Explanation:
Given the approximate value of completion = 17 hours
Exact value of completion = 19.5 hours
Absolute Error = Exact – Approximation
Absolute Error = 19.5 – 17 = 2.5
% Error =[tex]\frac{\text { Absolute Error }}{\text { Exact Value }} \times 100[/tex]
% Error =[tex]\frac{2.5}{19.5} \times 100=12.8 \%[/tex]
Therefore, the percent error is 12.8%
