## mikaa_toxica13 2 years ago I have an answer but I'm not sure I did it right. Can anyone check ?

1. mikaa_toxica13

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.

2. mikaa_toxica13

I simply did 58 - 45 ----- 13%

3. ganeshie8

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

4. E.ali

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

5. E.ali

@ganeshie8 :Realy right :)

6. mikaa_toxica13

I did my other questions that way but wasn't sure of the process. Hold on Ill use that equation

7. ganeshie8

okiee

8. E.ali

OK !:)

9. mikaa_toxica13

Ok I got 28

10. ganeshie8

close , try again

11. ganeshie8

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

12. mikaa_toxica13

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

13. ganeshie8

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

14. mikaa_toxica13

Oh I wrote it backwards

15. ganeshie8

yes :|

16. mikaa_toxica13

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

17. ganeshie8

Correct ! good job !!!

18. mikaa_toxica13

Thanks ! can u check another for me ?

19. ganeshie8

shoot

20. mikaa_toxica13

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

21. ganeshie8

Correct ! looks you got it perfectlyu !!!! always keep the ACTUAL in the bottom

22. E.ali

Very good !

23. mikaa_toxica13

Ok thanks !! :)

24. ganeshie8

np :)

25. E.ali

Do u have any question ?

26. mikaa_toxica13

Nope !
