Consider a file with a large number of Person(id, name, birth-date) records. Assume that users frequently search this file based on a the field id to find the values of name or birthdate for people whose information is stored in the file. Moreover, assume that users rarely update current records or insert new records to the file. Which file structure, heap versus sorted, provides the fastest total running time for users’ queries over this file? Explain your answer

Most calculators come with a book of instructions. Unfortunately, if you misplace the book, you’re left to your own devices in figuring out how to use the calculator. Wouldn’t it be easier if the calculator had a built-in “help” function similar to the one on your computer? You could just punch the “Help” key on your keypad and call up the relevant instructions on your display screen. You just invented a calculator with this feature, and you’re ready to roll it out. First, however, you have to make some pricing decisions: When you introduce the product, should you use skimming or penetration pricing? Which of the following pricing methods should you use in the long term: cost-based pricing, demand-based pricing, target costing, or prestige pricing? Prepare a report describing both your introductory and your long-term alternatives. Then explain and justify your choice of the methods that you’ll use.

    1. Responsive

    2. Interesting

  2. AIDA is a sequential model showing the states of mind that a person may go through while deciding what to buy. What does AIDA stand for?
    1. awareness, interest, design, action

    2. attention, information, desire, achievement

    3. awareness, interest, desire, attention

    4. attention, interest, desire, action

    5. awareness, information, desire, achievement

  3. Conviction stage in the hierarchy of effects model by Philip Kotler refers to the stage where
    1. Consumers may be converted to try out the product, but may like other brands too

    2. The doubt in consumers' minds about buying the product needs to be changed into action

    3. The purchase experience has to be made easy and enjoyable

    4. Your product is evaluated and compared against other brands

  4. The innovation adoption model implies that
    1. The challenge facing companies introducing new products or targeting new markets is to create awareness and interest among consumers

    2. The best way to evaluate a new product is through actual use so that performance can be judged

    3. Marketers could encourage trial by using demonstration or sampling programs or allowing consumers to use a product with a money-back commitment

    4. All of the other options

  5. Information processing model adds a stage that is not mentioned in all the other three models. This stage is

    1. Exposure

    2. Retention

    3. Attention

Create a method called “concat” that takes three char array parameters. This method should concatenate the second string on to the end of the first string and store the result in the third string. Note: When you concatenate two string you add the contents of one string on to another. Important: Make sure you add null terminators where necessary. No pointer.C++

The demand function for a truckload of firewood in a small town with a college is Q = 200 - 1.5p for non-students and Q = 200 - p for students, where p is the price of firewood, in $/truckload.

At a price of $150 per truckload, will college students buy any firewood?

At a price of $150 per truckload, will non-students buy any firewood?

The (inverse) demand curve for the town as a whole has a kink at Q =

An object (A) of mass m A = 28.0 kg is moving in a direction that makes angle of 50° south of west with a speed v A = 4.90 m/s, while object (B) of mass m B = 18.0 kg is moving due south with a speed v B = 7.85 m/s. The two objects collide and stick together in a completely inelastic collision. Find the magnitude of the final velocity of the two-object system after the collision.

Yahtzee Simulation. Must be written in Python

These are the specific instructions:

"Write a function called Yahtzee_Simulation() that receives no parameters. The function will simulate rolling 5 dice at least one million times. It will keep track of the number of times the computer rolls a Yahtzee. The function will return the number of wins divided by the number of tries. There are no print() statements in this function.

Write a function called main() that receives no parameters. This function calls the Yahtzee_Simulation() function 10 times and prints the result of each simulation. Finally, print the mathematical result, which can be calculated with the following code: print(6/(6**5))"

This was also given as a hint:

The simulation runs 1000000 times

League Competition: Suppose the demand for soccer teams in the US is given by: P(Q) = 320−10Q where Q is the total number of soccer teams and Pi s the marginal willingness to pay for the Qth team (in millions). The cost to start a new team is c= 20

Two Leagues: First, suppose are two leagues (Major League Soccer and the National Soccer League) that are choosing how many teams to have, so that Q=qm+qn.

a Find the equilibrium number of teams for the MLS.

b Find the equilibrium number of teams for the NSL.
