XYZ operates a movie theater. A movie ticket is $16.00 per ticket, and costs nothing. On average 40% of the customers will buy a soda ($6 each, cost $1); 60% will buy food ($6 average price with a cost of $2). The fixed costs are $387,600.

1. Calculate the break-even quantity and $sales for tickets, soda and food(10 points)  
2. The theater wishes to make $96,900 profit. Calculate the target profit quantity and sales for tickets, soda and popcorn (10 points)

Make sure to show your weighted average calculations, "bundle" calculations, and final answers.

One professor was interested in evaluating the overall performance of students in online sections. He wanted to know if students in an online section would do as well as students in a face-to-face section. So one semester he has the same class but one class was delivered in an online format and one section was delivered face-to-face and it served as a control section The grades of each section are listed below ,with 4.0=A down to 0.0=F A. Write out in words the Null and Alternative hypotheses for this situation B.Create a histogram of each class using the bins below. C.What is the correct statistical test to use satistically determine if there is a difference between the delivery methods.

Create a Park class. Include the following seven data members:

Name of Park

Location

Type of Park (National, State or Local)

Fee

Number of Employees

Number of visitors reported for the past 12 months

Annual Budget

Write your __init__ class

In addition write four separate instance methods that:

Return a string containing the name of the park, the location and type of park.

Computes the cost per visitor based on annual budget, and the number of visitors during the last 12 months.

Computes the revenue from fees for the past year based on number of visitors and fee.

Prints the values of all of the data members with appropriate labels.

Create a second class to test all aspects of your Park class.

-Write a function getMeASentence() that takes zero arguments, and its return type is string. This function will return a randomly generated sentence that abides by certain rules.

-The rules of this sentence are that there are 5 randomly generated lowercase letters, a space, a randomly generated inequality symbol, a space, and a randomly generated 1 digit number.

-In this context, an inequality symbol is understood to mean the "<", ">", or "=" symbol.

-Write a function isItCloseEnough(double, double, double) that takes three arguments of type double, num1, num2, and cutoff. Its return type is Boolean. It will return true if num1 and num2 are within a distance of cutoff, false otherwise. It is up to you to decide what value to return if the distance is exact.

-In your main function, write code that calls the getMeASentence() function 2 separate times, with appropriate labels, to test that it is working.

-In your main function, also write code to test the IsItCloseEnough(double, double, double) function by prompting the user to enter three numbers, and then call the function and output the results with appropriate labels. You should do this THREE times to test it properly.

Sample Output (remember that random values may vary)

Sentence 1: bksde > 6

Sentence 2: zloxr = 9

Enter 3 numbers: 2.1 2.3 0.3

Yes the numbers are within the cutoff.

Enter 3 numbers: 2.3 2.1 0.3

Yes the numbers are within the cutoff.

Enter 3 numbers: 2.3 2.1 0.1

No the numbers are not within the cutoff.

*Explanation*: In all cases, the distance between the two entered numbers is 0.2. If the cutoff is 0.3 units, then yes, the numbers are within the cutoff distance, but if the cutoff is 0.1 like that last case, then that is considered to be no.

1. Define a class called Odometer that will be used to track fuel and mileage for an automobile. The class should have instance variables to track the miles driven and the fuel efficiency of the vehicle in miles per gallon. Include a mutator method to reset the odometer to zero miles, a mutator method to set the fuel efficiency, a mutator method that accepts miles driven for a trip and adds it to the odometer’s total, and an accessor method that returns the number of gallons of gasoline that the vehicle has consumed since the odometer was last reset.

Use your class with a test program that creates several trips with different fuel efficiencies. You should decide which variables should be public, if any.

2. Write a grading program for a class with the following grading policies:

1. There are three quizzes, each graded on the basis of 10 points.

2. There is one miterm exm, graded on the basis of 100 points.

3. There is one finl exm, graded on the basis of 100 points.

The fnal exm counts for 40% of the grade. The miterm counts for 35% of the grade. The three quizzes together count for a total of 25% of the grade. (Do not forget to convert the quiz scores to percentages before they are averaged in.)

Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of 70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and any grade below 60 is an F. The program should read in the student’s scores and output the student’s record, which consists of three quiz scores and two exm scores, as well as the student’s overall numeric score for the entire course and final letter grade.

Define and use a class for the student record. The class should have instance variables for the quizzes, midterm, final, overall numeric score for the course, and final letter grade. The overall numeric score is a number in the range 0 to 100, which represents the weighted average of the student’s work. The class should have methods to compute the overall numeric grade and the final letter grade. These last methods should be void methods that set the appropriate instance variables. Your class should have a reasonable set of accessor and mutator methods, an equals method, and a toString method, whether or not your program uses them. You may add other methods if you wish.

3. Write a Temperature class that has two instance variables: a temperature value (a floating-point number) and a character for the scale, either C for Celsius or F for Fahrenheit. The class should have four constructor methods: one for each instance variable (assume zero degrees if no value is specified and Celsius if no scale is specified), one with two parameters for the two instance variables, and a no-argument constructor (set to zero degrees Celsius). Include the following: (1) two accessor methods to return the temperature—one to return the degrees Celsius, the other to return the degrees Fahrenheit—use the following formulas to write the two methods, and round to the nearest tenth of a degree:

DegreesC=5(degreesF−32)/9DegreesF=(9(degreesC)/5+32);

DegreesC=5(degreesF−32)/9DegreesF=(9(degreesC)/5+32);

(2) three mutator methods: one to set the value, one to set the scale (F or C), and one to set both; (3) three comparison methods: an equals method to test whether two temperatures are equal, one method to test whether one temperature is greater than another, and one method to test whether one temperature is less than another (note that a Celsius temperature can be equal to a Fahrenheit temperature as indicated by the above formulas); and (4) a suitable toString method. Then write a driver program (or programs) that tests all the methods. Be sure to use each of the constructors, to include at least one true and one false case for each of the comparison methods, and to test at least the following temperature equalities: 0.0 degrees C = 32.0 degrees F, –40.0 degrees C = –40.0 degrees F, and 100.0 degrees C = 212.0 degrees F.

Consider a Rankine cycle with an ideal intermediate steam pickup, one of which is open and the other is closed feed water heaters. The steam enters the turbine at 12.5 MPa pressure and 550 degrees Celsius temperature and expands to 10 kPa condenser pressure. The steam separated from the turbine at 0.8 MPa pressure is sent to the closed feed water heater and the steam separated at 0.3 MPa pressure is sent to the open feed water heater. The feed water is heated to the condensing temperature of the steam leaving the turbine in the closed heater. The steam comes out of the closed heater as a saturated liquid, then the pressure is lowered into a valve and sent to the open feed water heater. Show the cycle in a T-s diagram with saturated liquid and saturated vapor curves.
