Question

find the percent error of the measurement 7cm


help please

Answer 1

Is that all they gave you?

Answer 2

yes why is there suppose to be more?

Answer 3

If 7 is your only certain number, then it can be written with 2 significant figures, 7.0 - where the .0 is uncertain and is one-tenth of the unit of measure.

If the 7 itself is uncertain, then the true value could vary between 6.50 and 7.49.

%error = (margin-of-error/measurement)*100%

Answer 4

thank you so much
