Check all of the value that have 3 significant figures (check all that apply) a)0.0310 b)210.65 c)1.203 d)1.01

Hi!

The answer to your problem is A)0.0310 and D)1.01

A significant figure is any number that is not a stand-alone zero which means any zero in the middle of a sequence of numbers or at the end of a sequence of numbers is counted as significant, for example:
           these zeros are significant (1, 2, 3, and 4 is significant as well)
                |  |
0000123004
 |  | | |
these zeros are nonsignificant

It’s going to be d. 4x^2-4x-19’
