Pythagorean identities:

sine squared (theta) + cosine squared (theta) = 1. tangent squared (theta) + 1 = secant squared (theta). 1 + cotangent squared (theta) = cosecant squared (theta).

Which statement(s) are true based on the Pythagorean identities?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

What is the equation of a line passing through the point (6,1) and parallel to the line whose equation 3x=2y+4

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?
