Classify each of these statements as always true, sometimes true, or never true

11)sometimes true

12)Never True

11)Scientific notation is used to express large numbers in convenlent form.

12)Siginificant figures include all the digits that can be known accurately plus a last digit that must be estimated.

OK on the first, but on the second significant figures do not mean accurate, they mean precision.

If I measure the temp outside as 3.4545F, that is pretty precise (five sig figures), but it is very inaccurate. It is about 44F just now.

so the second one is always true?
