Answer 4

The error, or absolute error is defined as this:\[E_{absolute}=|x_{measured}-x_{accepted}|\]What does that mean that the absolute error will be?

Answer 5

im guessing that it will be x = | 124.1-125.7

Answer 6

Answer 7

i got 1.27287%

Answer 8

using my formula sheet

Answer 9

That is correct. And then the percent error is a value which shows how large the error is in relation to magnitude of the value. The equation is:\[E_{percent}=\frac{|x_{measured}-x_{accepted}|}{x_{measured}}\]

Answer 10

alright, that is what i used. thank you, for your help! :)

Answer 11

1.273% is correct.

No problem!
