these are our pure definition questions.

9. false

if the data was only defined for whole numbers, then that would be the only case, where that is true. but then, there would be no rounding.

the "significant figures" are the decimal places after the decimal point.

rounding it to one significant figure means rounding it to the first position after the decimal point.

10. True

see 9. for more details.
