A cancer researcher wants to test a new combination of chemotherapy and radiation on skin tumors in laboratory mice. The researcher administers the treatment to each of four laboratory mice having the type of skin tumor under study. After a week of treatment, the researcher records failure or success for each mouse, depending on whether or not skin tumor cells are observed on the animal. Problem 6-17 a asks us to write out the sample space for the problem. Let S represent the cancer disappears and F represents the cancer did not disappear. The sample space events are as follows: SSSS SSSF SSFF SFFF FFFF SSFS SFFS FSFF SFSS FFSS FFSF FSSS SFSF FFFS SFFS FSFS Suppose that the treatment combination has no effect on the skin tumors. However, there is a .1 probability…

Bill is trying to plan a meal to meet specific nutritional goals. He wants to prepare a meal containing rice, tofu, and peanuts that will provide 132 grams of carbohydrates, 150 grams of fat, and 134 grams of protein. He knows that each cup of rice provides 40 grams of carbohydrates, 0 grams of fat, and 1 grams of protein. Each cup of tofu provides 5 grams of carbohydrates, 15 grams of fat, and 20 grams of protein. Finally, each cup of peanuts provides 27 grams of carbohydrates, 75 grams of fat, and 32 grams of protein. How many cups of rice, tofu, and peanuts should he eat? cups of rice: cups of tofu: cups of peanuts:
Problem. Suppose you are having a dinner party for a large group of people, and you decide to make 2 gallons of chili. The recipe calls for 2 teaspoons of hot sauce per gallon, but you misread the instructions and put in 2 tablespoons of hot sauce per gallon. (Since each tablespoon is 3 teaspoons, you have put in 6 teaspoons per gallon, which is a total of 12 teaspoons of hot sauce in the chili.) You don't want to throw the chili out because there isn't much else to eat (and some people like hot chili!), so you serve the chili anyway. However, as each person takes some chili, you fill up the pot with beans and tomatoes without hot sauce until the concentration of hot sauce agrees with the recipe. Suppose the guests take 1 cup of chili per minute from the pot (there are 16 cups in a gallon), how long will it take to get the chili back to the recipe's concentration of hot sauce? How many cups of chili will have been taken from the pot?
I don't know how to accurately answer this question. I have followed the steps and have gotten 3 different answers each time. I am not sure which step I am missing or messing up on. I don't know if I am using the wrong formula but I would appreciate as much help as possible by guiding me through each step. Thank you so much.
Suppose electricians come in two types: competent and incompetent. Both types of electricians can get certified, but for the incompetent types, certification takes extra time and effort. Competent ones have to spend (M) months preparing for the certification exam; incompetent ones take twice as long, i.e. (2M). The cost of preparing for the exam is 2 (thousand dollars) per month for a competent type and 4 (thousand dollars) per month for an incompetent type. Assume that both types will pass the exam and get certified if they spend the corresponding required amount of time (M months for the competent type and 2M months for the incompetent type) preparing. Certified electricians can earn 120 (thousand dollars) each year working on building sites for licensed contractors. Uncertified electricians can earn only 80 (thousand dollars) each year in freelance work; licensed contractors will not hire uncertified electricians. Each type of electrician's payoff is equal to their salary minus the…
