I am very new to postulates and geometry itself. Could someone do these problems very quick and also explain which one since postulates are very confusing for me. Please and thank you.

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.)

The cost of using a service is $0.25 per min. what equation correctly represents the total cost c, in dollars, for d days of use?

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2
