Question

now, go to the board as directed by the instructor and add your rules to the appropriate section. after the class discussion and editing session, write the final sf rules on your note - card. exercises complete the following table: number # of sf group above (1 - 7) that this number would fit into 2.307 4 5 4 5.230 5 271.2 1.750 x 10^(-3) 7 4 6 5000 3

Explanation:

Step1: Determine significant - figures rules

Non - zero digits are always significant. Zeros between non - zero digits are significant. Trailing zeros in a number with a decimal point are significant.

Step2: Analyze 5.230

The number 5.230 has 4 significant figures as all the digits (5, 2, 3, 0) are significant.

Step3: Analyze 271.2

The number 271.2 has 4 significant figures (2, 7, 1, 2).

Step4: For the number with 5 significant figures and group 4

A possible number could be 12.345 (answers may vary).

Step5: For the number with 4 significant figures and group 6

A possible number could be 3.456 (answers may vary).

Step6: Analyze 5000

If no decimal point is given, 5000 has 1 significant figure.

Answer:

12.345 (example)	5	4
5.230	4	5
271.2	4	-
1.750 x 10⁻³	4	7
3.456 (example)	4	6
