Significant Figures- rules - correct answer-1) ALL non-zero numbers (1,2,3,4,5,6,7,8,9) are
ALWAYS significant.
2) ALL zeroes between non-zero numbers are ALWAYS significant.
3) ALL zeroes which are SIMULTANEOUSLY to the right of the decimal point AND at the end
of the number are ALWAYS significant.

ALWAYS significant.
Observation - correct answer-process of gathering data
Inference - correct answer-making decisions about the gathered data
Qualitative - correct answer-descriptions; no numbers
