Hi,

I'm trying to make a basic GUI quiz in python using tkinter.

I would like the user to have to press a start button to begin the quiz and then be asked 5 different questions with the total score showing at the end. Ideally it would be a multiple choice quiz with the user having 4 different answers to choose from.

A very basic example of this would be appreciated so I can understand where exactly I'm going wrong.

Thanks in advance

Consider the following information about Stocks A and B: Rate of Return if State Occurs State of Probability of Economy State of Economy Stock A Stock B Recession 0.26 0.03 − 0.34 Normal 0.56 0.20 0.14 Irrational exuberance 0.18 0.09 0.54 The market risk premium is 5 percent, and the risk-free rate is 3 percent. (Round your answers to 2 decimal places. (e.g., 32.16)) The standard deviation on Stock A's return is percent, and the Stock A beta is . The standard deviation on Stock B's return is percent, and the Stock B beta is . Therefore, based on the stock's systematic risk/beta, which Stock is "riskier".

Discuss how, why, and where a critical incident technique is used.

You are considering making a movie. The movie is expected to cost $ 10.2 million up front and take a year to produce. After​ that, it is expected to make $ 4.9 million in the year it is released and $ 2.1 million for the following four years. What is the payback period of this​ investment? If you require a payback period of two​ years, will you make the​ movie? Does the movie have positive NPV if the cost of capital is 10.6 %​?
What is the payback period of this​ investment?

What effects would each of the following have on aggregate demand or     aggregate supply? Justify your answer. In each case use a diagram to show the expected effects on the equilibrium price level and real output level in the economy. Assume that all other things remain constant and prices are inflexible downward.

(a) A reduction in interest rates at each price level.

(b) A sizable increase in labor productivity.

(c) The nation’s currency appreciates against its major trading partners .

/*
The following function receives the class marks for all student in a course and compute standard deviation. Standard deviation is the average of the sum of square of difference of a mark and the average of the marks. For example for marks={25, 16, 22}, then average=(25+16+22)/3=21. Then standard deviation = ((25-21)^2 + (16-21)^2+(22-21)^2)/3.
Implement the function bellow as described above. Then write a test console app to use the function for computing the standard deviation of a list of marks that user inputs as floats in the range of 0.f to 100.f. User signals end of the list by entering -1 as final mark. Make sure to verify user input marks are valid and in the range, before processing them.

Consider the following information: Rate of Return if State Occurs State of Probability of Economy State of Economy Stock A Stock B Stock C Boom 0.60 0.09 0.18 0.36 Bust 0.40 0.15 0.07 − 0.05 a. What is the expected return on an equally weighted portfolio of these three stocks? (Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16)) Expected return % b. What is the variance of a portfolio invested 15 percent each in A and B and 70 percent in C?

WRITE IN C++

Create a class named Coord in C++

Class has 3 private data items

              int xCoord;

              int yCoord;

              int zCoord;

write the setters and getters. They should be inline functions

              void setXCoord(int)             void setYCoord(int)            void setZCoord(int)

              int getXCoord()                     int getYCoord()                   int getZCoord()

write a member function named void display() that displays the data items in the following format

     blank line

     xCoord is                          ????????

     yCoord is                          ????????

     zCoord is                          ????????

    Blank line

Example

     blank line

     xCoord is                          101

     yCoord is                          -234

     zCoord is                          10
