his last trip to the hardware store, but he knows the distance traveled is 15 miles. What is the percent
error? Use a calculator and the percent error formula to help find the answer. Show your steps.
HELP WITH EQUATION
Answers
I think the answer its 1.8 percent because if you subtract 15-13.2 comes out to be 1.8.
but l also think it could be 12 percent error.
The odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is [tex]12 \%[/tex] .
What is percentage ?A percentage is a number or ratio that can be expressed as a fraction of 100. And is denoted using the percent sign, "[tex]\%[/tex]".
Percentage [tex]=\frac{Diffeerence \ in \ value}{Total \ value}[/tex]
We have,
Last trip to the hardware store [tex]=13.2[/tex] miles
Original trip to the hardware store [tex]=15[/tex] miles
So,
Using the above given formula;
Percentage error [tex]=\frac{Diffeerence \ in \ value}{Total \ value}*100[/tex]
[tex]=\frac{15-13.2}{15} *100[/tex]
[tex]=\frac{1.8}{15} *100[/tex]
[tex]=12 \%[/tex]
So, the Percentage error in the odometer is [tex]12 \%[/tex] which is find out using above given formula.
Hence, we can say that the odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is [tex]12 \%[/tex] .
