What is the percent error in Clara's estimate, to the nearest tenth of a percent?

A. 7.7%

B. 8.0%

C. 11.0%

D. 11.5%

I think it is D. 11.5%, but I am not sure.

Respuesta :

5.75 is 92% of 6.25. Meaning that the answer is B. 8.0%. To figure this out you simply need to take her estimate, 5.75, and put it in fraction form, with the denominator being the actual total, 6.25. So it would look like this. 5.75/6.25= 0.92. 0.92 equals 92%. Subtract 92 from 100 and you get 8%

The percent error is 8.0%.

Given that,

  • Clara estimates that the length of a hiking trail is 5.75 kilometers.
  • She later learns that its actual length is 6.25 kilometers.

Based on the above information, the calculation is as follows:

[tex]= (5.75 - 6.25) \div 6.25[/tex]

= 8.0%

Therefore we can conclude that The percent error is 8.0%.
