    Find the percent error in each estimation. Round to the nearest percent. You estimate that a tree is 45 ft tall. It is actually 58 ft tall.

    percent error = actual - measured ------------------ x 100 actial

    OK ! 13 is right but we have : 13 _________x 58________100 Got it ? we want % of estimate .:)

    percent error = actual - measured ------------------ x 100 actial percent error = 58- 45 ------------------ x 100 58

    ok this is what I did x = 45ft - 58ft ----------(100) 45ft 45 - 58 = -13 --- = .28 (100) = 28% 45

    Yo read the q again, actual = 58 measured = 45

    ok this is what I did x = 58ft - 45ft ----------(100) 58ft 58 - 45 = -13 --- = .22 (100) = 22% 58

    a carpenter estimates the wall is 20ft tall The wall is actually 18ft tall. x = 18ft - 20ft ----------(100) 18ft 18 - 20 = -2 --- = .11(100) = 11% 18
