According to the rules of significant figures, the number of digits that are estimated in a measurement is: A. one. B. two. C. three. D. none.
it doesn't give me a number that is the question!
i think it is a for 2 reasons. First the grammar. They say is instead of are. and the last digit is just one like 14 : you can say 14 +- a tenth 14.1 +- a hundreth and so on. you only estimate the last digit which is one digit. I think
okay thank you so much ... i thought it was 3 but i got it wrong.
