Find a + b, 2a + 3b, |a|, and |a − b|. a = i + 4j − 2k, b = −4i − j + 6k

Which is the scale factor proportion for the enlargement shown?

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.

Pls i’m super dumb and i need with this one it’s due tomorrow
