Suppose you are giving the outcome returns of some assets under different scenarios. The probability for the bearish, neutral and bullish market is 20%, 50% and 30%.

Please answer the following questions

Q1(1 point) What are the correlations between A and all other assets?

Q2 (1 point) How do you form MVP from asset A and B only (find the weights)?

Q3(1 point) What is the equation representing the efficient frontier for the above case in Q2?

Q4(1 point) How do you form the MVP based on asset A and C only, assuming short selling is allowed?

Q5(1 point) What is the equation representing the EF for the Q4 case?

Q6(1 point) What is the optimal RISKY market portfolio if asset A and D are the only two risky assets?

Q7(2 points) What is the optimal portfolio for an risk averse investor with A=200 is there are only asset A and D and risk free asset?

Q8(2 points) Assume the market portfolio has std of 3%, and the beta of asset A is 0.6, to what extend the expected return of asset A can be explained by singleindex model using the given market portfolio as the market index, and how much is the unsystematic risk based on this single-index model ?

Whenever I am attempting to write a simple program on C++ I get an error message that reads "cout was not declared in this scope". Literally every time. This has become frustrating because I have even written my code the exact same way as some of my classmates who got theirs to compile and run with no sign of this error at all, and yet min gives this answer. I will leave an example of a code where this error message appeared. Hopefully you can help. Thank you.

ex:

// Example program
#include <iostream>
#include <string>

int main()
{
double mass, velocity,energy;
cout<<"\n enter the objects weight";
cin>>mass;
cout<<"\n enter the objects velocity"
cin>>velocity;
energy=(1.0/2.0)*(mass*velocity)*2;
cout<<"\n mass = "<<mass<<"kg";
cout<<"\n velocity = "<<velocity<<"m/s";
cout<<"\n kinetic energy = "<<energy<<"kgm/s";
}

Here's the error message:

In function 'int main()': 8:1: error: 'cout' was not declared in this scope 8:1: note: suggested alternative: In file included from 2:0: /usr/include/c++/4.9/iostream:61:18: note: 'std::cout' extern ostream cout; /// Linked to standard output ^ 9:1: error: 'cin' was not declared in this scope 9:1: note: suggested alternative: In file included from 2:0: /usr/include/c++/4.9/iostream:60:18: note: 'std::cin' extern istream cin; /// Linked to standard input ^

How can I configure the button in this tip calculator to calculate the total using the entires for the bill and tip percentage? I'm using Visual Studio 2019 Xamarin.Forms

Everything above should be good to go, I just can't figure out how to get some actual calculations done with the other page of my code.

Question 3 – Capital Investment Analysis

The management team of Accent Group Limited have received a proposal from the manager of Hype DC. This proposal concerns a major upgrade to Hype DC's stores to improve the customer experience. Key details relating to this proposal include:

• The initial cost will be $22 million. This cost will be depreciated using the straight line method over the 5 year life of the upgrade.
• During year 1, the firm will increase marketing costs by $2.0 million to promote the store upgrades.
• Over the five year life of the project, it is expected that the upgrade will increase the firm's sales by $18 million per year. On average, cost of sales is 45% of revenue.
• The firm will need to higher additional staff over the life of the project to help to deal with the increased sale volume. In year 1, the firm's staffing costs will increase by $1.0 million. These costs will increase by 3.5% p.a.
• The upgrade is expected to increase the firm's energy costs by $500,000 in year 1. This increase will be ongoing across the life of the project and will increase by 6% p.a.
• Upgraded stores will include an old shoe recycling drop off zone. This recylcing program will cost $75,000 in year 1. These costs will increase by 2% p.a.
• At the end of year 3, the firm will spend $1.5 million on a minor refurbishment to the stores.

The firm’s tax rate is 30%. The firm requires a 16% required rate of return on all potential investments.

Required

In relation to the above proposal:

1. Calculate the annual after tax cash flows and annual after tax profit

(show with workings please)

For C code: Do not use any function other than getchar, scanf, and printf

Q2.A) Write a program to do the following: Read in two values into variables X   and y from the keyboard (they may be decimal values like 2.3). Read in a 3^rd value (which is really small < 1.0 ) into variable E. Using a loop find out the value of N in the below expression. i.e. Each iteration of the loop reduced the value of Y by dividing it by 2. Print out N at the end when the condition is met. For most input X and Y values the condition may not become true and the loop would become an infinite loop. To break from such "traps", you can have a loop count and break away. i.e. Count how many iterations it has run through the loop body, and if it goes over some number, say 100, just use "break" after saying "there is no solution for the given numbers" which should end the program.  

Note: This program conveys the convergence vs divergence in numerical methods.

(a) Let X = 1.02 Y = 8.1, E = 0.05. In each iteration Y/2^N values become 8.1, 4.05, 2.025, 1.0125, and stops since X - 1.0125 is 0.0075 which is < E. This starting Y value converges toward a solution.

(b) If X = 1.02 and Y = 9.5, then it would not converge to a solution to meet the criterion, but diverges away. Y/2^N value become 4.75, 2.375, 1.1875, 0.59375, 0.2968,goes to 0, but difference goes up.   

Iconic memory is a type of memory that holds visual information for about half a second (0.5 seconds). To demonstrate this type of memory, participants were shown three rows of four letters for 50 milliseconds. They were then asked to recall as many letters as possible, with a 0-, 0.5-, or 1.0-second delay before responding. Researchers hypothesized that longer delays would result in poorer recall. The number of letters correctly recalled is given in the table.

(a) Complete the F-table. (Round your values for MS and F to two decimal places.)

(b) Compute Tukey's HSD post hoc test and interpret the results. (Assume alpha equal to 0.05. Round your answer to two decimal places.)

The critical value is_______ for each pairwise comparison.

Which of the comparisons had significant differences? (Select all that apply.)

A.) The null hypothesis of no difference should be retained because none of the pairwise comparisons demonstrate a significant difference.

B.) Recall following no delay was significantly different from recall following a half second delay.

C.) Recall following a half second delay was significantly different from recall following a one second delay.

D.) Recall following no delay was significantly different from recall following a one second delay.
