Christine takes classes at both Westside Community College and Pinewood Community College. At Westside, class fees are $98 per credit hour, and at Pinewood, class fees are per S115 credit hour. Christine is
taking a combined 20 total of credit hours at the two schools.
Suppose that she is taking w credit hours at Westside. Write an expression for the combined total dollar
amount she paid for her class fees.

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.)

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

What is the frequency of the sinusoidal graph?
