- Kentville, a community of 10,000 people, resides next to a krypton mine, and there is a concern that the emission from the krypton smelter have resulted in adverse effects. Specifically, Kryptonosis seems to have killed 12 of Kentville’s inhabitants last year. A neighboring community, Lanesburg, has 25,000 inhabitants and is far enough from the smelter to not be affected by the emission. In Lanesburg, only three people last year died of Kryptonosis. Given that the number of deaths in Kentville and their causes last year were: Heart attack=7 Accidents=4 Kryptonosis=12 Other=6 What is the risk of dying of Kryptonosis in Kentville relative to non-contaminated locality?What is the risk of dying of Kryptonosis in Kentville relative to deaths due to other causes? How many times the chance of dying of Kryptonosis compared to dying of accidents ? How many times the chance of dying of Kryptonosis compared to Other causes?Television has become one of the major sources of health information of all types. In addition to news programs that report results of medical "breakthroughs" and discoveries of new drugs to treat chronic health conditions, televised medical talk shows have become very popular sources of medical information. Two medical talk shows with high viewership are The Dr. Oz Show and The Doctors, each with over 2 million viewers per daily show. Both shows provide recommendations related to diet (such as immune boosting diets), weight-loss, and a wide variety of general medical topics. These shows typically make 11 or 12 recommendations per one-hour episode. The medical talk shows, particularly The Dr. Oz Show, frequently generate skepticism and criticism from medical professionals. Scientific evidence to support the recommendations is often not presented and information indicating possible conflict of interest is given for only a tiny fractional percentage of the recommendations. In a recent…With a terrain and make of concrete, experience from national highways suggests that there are, on the average, 2 potholes per mile after a certain amount of usage. We wish to know how likely it is to find no more than one pothole in a section of 5 miles of a highway. What is the average number of potholes in a section of 5 miles of a certain highway?
- You are the marketing director for a company that manufactures bodybuilding supplements and you are planning to run ads in Sports Illustrated and GQ Magazine. Based on readership data, you estimate that each one-page ad in Sports Illustrated will be read by 670,000 people in your target group, while each one-page ad in GQ will be read by 170,000. You would like your ads to be read by at least 3 million people in the target group and, to ensure the broadest possible audience, you would like to place at least three full-page ads in each magazine. Draw the feasible region that shows how many pages you can purchase in each magazine. (Let x be the number of full-page ads in Sports Illustrated and let y be the number of full-page ads in GQ Magazine.) Find the corner points of the region. (Round each coordinate to the nearest whole number. If an answer does not exist, enter DNE.) smaller x-value(x, y) = larger x-value(x, y) =twinit9A Gallup survey showed that in March 2011 , 8 of every 25 employers in the United States were adding more workers to their workforce, 9 of 50 were reducing their workforce, and 1 of 2 were keeping it the same. In a metropolitan area there are 1250 employers and of those who will hire, they will hire an average of seven new employees. If the employers who were cutting their workforce in that area were planning on letting go an average of nine workers, what would the net change in jobs for the area be? This metropolitan area would see a ▼net decrease or increase of jobs.
- please help with 3, 4, and 5 High school seniors with strong academic records apply to the nation’s most selective colleges in greater numbers each year. Because the number of slots remains relatively stable, some colleges reject more early applicants. Suppose that for a recent admissions class, an Ivy League college received 2851 applications for early admission. Of this group, it admitted 1033 students early, rejected 854 outright, and deferred 964 to the regular admission pool for further consideration. In the past, this school has admitted 18% of the deferred early admission applicants during the regular admission process. Counting the students admitted early and the students admitted during the regular admission process, the total class size was 2375. Let E, R, and D represent the events that a student who applies for early admission is admitted early, rejected outright, or deferred to the regular admissions pool.
