Question

Ivan estimated the volume of his bathtub to be 31gal . The actual volume of his bathtub was 37gal.
Find the absolute error and the percent error of Ivan's estimate. If necessary, round your answers to the nearest tenth

Answer 1

is percent error 60.3?

Answer 2

no

Answer 3

@slimjim77 When you find absolute error, it is:

(absolute value of the difference between actual and esimated volume) divided by actual volume

= (37-31)/37 = 6/37 = 16.2%

Answer 4

Absolute Error is equal to the absolute value of the difference of the estimated and actual. In this case, it is 6 gal. Percent Error is equal to the Absolute Error divided by the Actual value. In this case, it is 16.21%.

Answer 17

Kira is estimating the height of her office building. The actual height of her office building is 10.4 . Kira's estimate is 11 .
Find the absolute error and the percent error of Kira's estimate. If necessary, round your answers to the nearest tenth.

Answer 18

so i did (11-10.4)/11-0.6/11

Answer 19

its not correct and im not sure wats wrong

Answer 20

Why did you do 11 - 0.6?
You should have done .6 / 10.4.

Answer 21

Which is about 5.8%.

Answer 22

You have to divide by the ACTUAL measurement.

So it is .6/10.4 = 5.8%
