The materials used in one shirt cost;$8 and Gina can sell these for $15 each;(a) If Gina sell 20 shirts what will her;total revenue be? What will her total variable cost be?;(b) How many shirts must Gina sell to break;even? What is the total revenue for this?;1-20: Mysti Farris (see problem 1-19) is considering raising the selling price;of each cue to $50 instead of $40.

Last;year, at Northern Manufacturing Company, 200 people had colds during the year.;One hundred fifty-five people who did no exercising had colds, while the;remainder of the people with colds were involved in a weekly exercise program.;Half of the 1,000 employees were involved in some type of exercise.;a. What;is the probability that an employee will have a cold next year?;b. Given;that an employee is involved in an exercise program, what is the probability;that he or she will get a cold?;c. What;is the probability that an employee that is not involved in an exercise program;will get a cold next year?;d. Are;exercising and getting a cold independent events? Explain your answer.;David Mashley teaches two undergraduate;statistics courses at Kansas College. The class for Statistics 201 consists of;7 sophomores and 3 juniors. The more advanced course, Statistics 301, has 2;sophomores and 8 juniors enrolled. As an example of a business sampling;techinique, Professor Mashley randomly selects, from the stack of Statistics;201 registration cards, the class card of one student and then places that card;back in the stack. If that student was a sophomore, Mashley draws another card;from the Statistics 201 stack, if not, he randomly draws a card from the;Statistics 301 group. Are these two draws independent events? What is the;probabilty of;(a) a junior's name on the first draw;(b) a junior's name on the second draw;given that a sophomore's name was drawn first?;(c) a juniors's name on the second draw;give that a junior's name was drawn first?;(d) a sophomore's name on both draw's?;(e) a junior's name on both draw's?;(f) one sophomore's name and one;junior's name on the two draws, regardless of order drawn?;2-24: The;Boston South Fifth Street Softball League consists of three teams: Mama?s Boys;team 1, the Killers, team 2, and the Machos, team 3.

There are 10 questions on a;true?false test. A student feels unprepared for this test and randomly guesses;the answer for each of these.;(a)What is the probability that;the student gets exactly 7 correct?;(b)What is the probability that the student;gets exactly 8 correct?;(c)What is the probability that;the student gets exactly 9 correct?;(d)What is the probability that the student;gets exactly 10 correct?;(e)What is the probability that the student;gets more than 6 correct?
