Answer:
6.9%.
Step-by-step explanation:
From the given information it is clear that
Estimated distance from Mark's house to his school = 15.5 mi
Actual distance = 14.5 mi.
We need to find the percent error in Mark's estimate.
[tex]\text{Percent error}=\dfrac{\text{Estimated Distance - Actual Distance}}{\text{Actual Distance}}\times 100[/tex]
[tex]\text{Percent error}=\dfrac{15.5-14.5}{14.5}\times 100[/tex]
[tex]\text{Percent error}=\dfrac{1}{14.5}\times 100[/tex]
[tex]\text{Percent error}=\dfrac{100}{14.5}[/tex]
[tex]\text{Percent error}=6.8965517[/tex]
Round the percent to the nearest tenth.
[tex]\text{Percent error}\approx 6.9[/tex]
Therefore, the percent error is 6.9%.
