Question

11) How many significant figures would be in your correctly rounded

answer: 230 x 4.88 X.0643*
Is it 1,2,3,4?

Answer 1

2

Step-by-step explanation:

Unfortunately, despite the careful measurements of the last two numbers, the first only tells us a measurement in the tens is accurate. The zero is a placeholder. If the numbner were written 230.0, it would have 4 sig figs, but the number as written only has two sig figs.
