Answer:
The percent error in this measurement is 0.194%.
Step-by-step explanation:
Given : A radar gun measured the speed of a baseball at 103 miles per hour. If the baseball was actually going 102.8 miles per hour.
To find : What was the percent error in this measurement?
Solution :
The actual speed is 103 miles per hour.
The estimated speed is 102.8 miles per hour.
The percentage is given by,
[tex]\text{Percentage}=\frac{\text{Actual-Estimated}}{\text{Actual}}\times 100[/tex]
[tex]\text{Percentage}=\frac{103-102.8}{102.8}\times 100[/tex]
[tex]\text{Percentage}=\frac{0.2}{102.8}\times 100[/tex]
[tex]\text{Percentage}=0.194\%[/tex]
Therefore, the percent error in this measurement is 0.194%.
