a) John is doing a math quiz, which has 10 questions where each question has four outcomes (A, B, C & D) but only one is correct. After the quiz, John told you he didn't study for the test at all and guessed all answers. i) If John guessed each and every item in the test, describe the probability distribution for the number of correct guesses. Present the probability distribution in the form of a table using 4 decimal ppints...
Resling Travel offers helicopter service from suburban towns to John F. Kennedy International Airport in New York City. Each of its 14 helicopters makes between 1,300 and 2,300 round-trips per year. The records indicate that a helicopter that has made 1,300 round-trips in the year incurs an average operating cost of $600 per round-trip, and one that has made 2,300 round-trips in the year incurs an average operating cost of $450 per round-trip.

1. A statistics professor posted 10 review problems on probability distributions: 4 problems were on discrete distributions and 6 on continuous distributions. He then announced to his students that he will randomly select 3 problems out of those posted problems and use them on the midterm exam. Let X be the number of posted problems the professor ends up using on the exam that deal with discrete distributions. a. How many different selections of 3 problems are possible? b. Find...
Roy Travel offers helicopter service from suburban towns to John F. Kennedy International Airport in New York City. Each of its 10 helicopters makes between 900 and 1,800 round-trips per year. The records indicate that a helicopter that has made 900 round-trips in the year incurs an average operating cost of $385 per round-trip, and one that has made 1,800 round-trips in the year incurs an average operating cost of $250 per round-trip. Read the requirements. 1 Requirements Requirement 1....
1. Prof. Ronald Coase's seminal 1960 paper asks us to imagine the following scenario. A farmer and a cattle rancher are operating on neighboring properties. Inevitably, some of the rancher's cattle manage to stray onto the farmer's plot, damaging the crops and rendering them worthless. Now, consider the following numerical example: Suppose the cost to build a fence between the two properties that is strong enough to keep the cattle penned in is $10,000. The cattle rancher earns a profit...
John Smith operates a sandwich truck with which he visits construction projects and industrial areas. His sandwiches are very popular for their freshness and quality because John uses the best quality ingredients that he buys daily, very early in the morning, from his supplier. The ingredients he buys every day are: Ingredients Cost 24 pounds of turkey breast prepared in the oven $170 30 pounds of honey-cured ham 135 24 pounds of roast beef 189 24 pounds of swiss cheese...
3. Consider the following piecewise function (a) Draw an accurate graph of f(). (b) As always, f(x), has an infinite number of antiderivatives. Consider an antiderivative F(r). Let us assume that F(r) is continuous (we don't usually have to specify this, but you will see in the bonus part of the question why we do in this case). Let us further assume that F(2) 1. Sketch an accurate graph of F(r). MATH 1203 Assignment #7-Integration Methods Due: Thurs., Apr. 4...
1. When applying the Integral Test, it is not entirely correct to say that the value of the integral tells us nothing about the value of the infinite sum. We can use an improper integral to find upper and lower bounds for the value of the sum. That is, if f is a continuous, positive, decreasing function on [1, oo), and f(n) an, then a) Use pictures (and words) to show why these inequalities are true. (Hints: Do one inequality...
5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N. Construct a free body diagram showing all the forces acting upon...
