or B
jim_thompson5910
Best Response

1
either A or D I think

1
hmm which one should we choose then?
jim_thompson5910
Best Response
You've already chosen the best response.

something like 0.000000501 has 3 sig figs (5, 0, 1) because the zeros in front aren't counted

You've already chosen the best response.
1
something like 7,000,000 has only 1 sig fig
jim_thompson5910
Best Response
You've already chosen the best response.
1
but if you said 7,000,000.0, then it would have 7 sig figs
katlin95
Best Response
You've already chosen the best response.
1
so then we should pick A right?
jim_thompson5910
Best Response

1
D could be lumped together with C somehow, not sure though
jim_thompson5910
Best Response
You've already chosen the best response.
