Question

the standard length of a football field 4,320 inches long. you measure your local football field and it measures at 4,225 inches. what is the percent error? % error = \frac{|accepted - average|}{accepted} \times 100 0.022 percent error 78 percent error 2.2 percent error 0.78 percent error

Explanation:

Step1: Identify accepted and measured values

Accepted length ($accepted$) = 4320 inches, Measured length ($average$) = 4225 inches.

Step2: Calculate the absolute difference

$\vert accepted - average \vert = \vert 4320 - 4225 \vert = 95$

Step3: Apply the percent error formula

$\% Error = \frac{\vert 4320 - 4225 \vert}{4320} \times 100 = \frac{95}{4320} \times 100 \approx 2.2\%$

Answer:

2.2 percent error
