Question

Select all that apply. Which of the following statements are true? Significant figures are an indicator of the certainty in measurements Significant figures communicate the level of precision in measurements Significant figures in a measurement are all measured digits, and one estimated digit None of the above

Answer 1

Significant figures communicates the level of precision in measurements.

Answer 2

Significant figures are an indicator of the certainty in measurements

Significant figures communicate the level of precision in measurements

Step-by-step explanation:

As the number of significant figures increases the precision of measurement increases hence a number with 3 significant figures is more precise than a number with 2 significant figures. Also the certainty of measurement increases with the increase in the number of significant figures. A number with 4 significant figures is more certain than a number with 2 significant figures.
