How do you find the percent error? Explain in words.

Percent error is the difference between the actual value and the estimated value compared to the actual value and is expressed in a percentage format.

Percent Error = {(Actual Value - Estimated Value)/Actual Value} × 100.

Percent errors indicate how huge our errors are when we measure something

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
