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, what was the percent error in this measurement? Round to the nearest hundredth percent

Sagot :

Answer

Percent Error = 0.195%

Explanation

Percent error is given as

[tex]\text{Percent Error = }\frac{Error}{True\text{ value}}\times100\text{ percent}[/tex]

Error = | (Incorrect value) - (True value) |

Incorrect value = 103 miles per hour

True value = 102.8 miles per hour

Error = | (Incorrect value) - (True value) |

Error = | 103 - 102.8 |

Error = 0.2 miles per hour

[tex]\begin{gathered} \text{Percent Error = }\frac{Error}{True\text{ value}}\times100\text{ percent} \\ \text{Percent Error = }\frac{0.2}{102.8}\times100\text{ percent} \\ \text{Percent Error = 0.195 percent} \end{gathered}[/tex]
