Combining two assets having perfectly negatively correlated returns will result in the creation of a portfolio with an overall risk that A. increases to a level above that of either asset B. decreases to a level below that of either asset C. stabilizes to a level between the asset with the higher risk and the asset

I have 8 players and all 8 play on friday only (making two foursomes). We will be playing for a total of 18 weeks. How should they be set up for each different friday so that at the end of 18 weeks they will have played in a foursome with every other player an equal number of times? ( or as close to equal as possible)

I need help on this question- A quantitative method may be sensitive to changes in the parameters involved in comparing alternatives. A careful analyst conducts a sensitivity analysis to see if the situation's outcome is susceptible to small changes in such parameters (say 5%). Is Decision Analysis susceptible to such a s

Argument: All planes fly in the air. The Boeing 737 jet is a plane. By deductive reasoning, one can conclude, ... 3

Part 1: Find the average weight in pounds of a type of bird of your choice. Use the rational exponent equation L = 2.43 * W^0.3326 to estimate the wingspan L in feet of the bird that weighs W pounds (Rockswold, 2006). Include in your post the type of bird and the average weight and show the calculations necessary to find the app

Consider the nonhomogeneous linear initial value problem x^2y'' - 2xy' + 2y = 30x(delta)(x - 3), y(1) = 1, y'(1) = 0 Note that y(x) = x satisfies the corresponding homogeneous differential equation. Solve the initial problem using a Green's function approach. What happens to y, y' and y'' at x=3?

Waverly Products has found that its revenue is related to advertising expenditures by the function R (x) = 5000 + 16x - 3x2 ,where R(x) is the revenue in dollars when x hundred dollars are spent on advertising. a) Find the marginal revenue function. b) Find and interpret the marginal revenue when $1000 is spent on adverti

Examine several newspapers and magazines and describe at least three examples of functions that appear. What is the domain and range of each function? EXAMPLE OF ASSIGNMENT: The amount of money you pay for a gym membership is a function, because you pay a fee each month in addition to the initial fees for joining. In thi

Think of a mathematical function that represents something from your own life. For example, suppose the number of beers you drink depends on the number of football games you watch. If you drink five beers during every football game, the function would be: Number of Beers (B) = 5 times Number of Football Games (F), or B = 5F

In a bumper test, three types of autos were deliberately crashed into a barrier at 5 mph, and the resulting damage (in dollars) was estimated. Five test vehicles of each type were crashed, with the results shown below. Are the mean crash damages the same for these three vehicles? Please see the attached file for the fully for

The sum of two numbers is greater than or equal to 30 . The second number is 6 more than the first. What are the possible values for the first of the two numbers? In your answer, denote the first number by x .

Define Ruler Function g:(0,1)-> R (it is the usual ruler function available online) as g(x) = { 1/q if x = p/q, p and q are relatively prime { 0 if x is irrational. Show (without using Riemann-Lebesgue Theorem) that g is Riemann integrable. The hint says that since L (lower sum) is zero, it remai

Prove that an entire function that omits the value 0 and 1 is a constant. See the attached file.

Two related questions. First - I need a good way to display error bars on a scatter plot. I have a set of x and y data, that I have attached as a text file along with y+err and y-err data (denoted +/-). The err values vary from point to point, and +err and -err are not necessarily the same. Second - I am using the data to

This Discussion Question will concentrate on functions and graphs. Understanding the definitions of words is the essence of mathematics. When we understand the meaning of words, finding a solution is much easier because we know what task the problem is asking us to complete. a. Part 1 b. In your own words, define the wo

1. What is an inverse function? In order for a function to have an inverse it must be a one-to-one function. Explain in your own words what it means to be a one-to-one function and why this is a necessary requirement for having an inverse. Give a simple example of a function and its inverse. Explain why these functions are in
