So how do I figure this out since I have a huge test on it I don’t understand it that well and please at least show work or an explanation please it would help a lot.

2people are trying different phones to see which one has the better talk time. chatlong has an average of 18 hours with a standard deviation of 2 hours and talk-a-lot has an average of 20 hours with a standard deviation of 3. the two people who tested their phones both got 20 hours of use on their phones. for the z-scores i got 1 for the chatlong company and 0 for talk-a-lot. what is the percentile for each z-score?

Using inductive reasoning, what are the next two number in this set? 2,3/2,4/3,5/4,

What is the ordered pair of m’ after point m (5, 6) is rotated 90° counterclockwise?
