Regarding clinician use of the EMR/EHR, when is the best time to access and document into the EMR/EHR? Explain.

1. please include calculations/explanations to all answersYou are currently only invested in the Natasha Fund (aside from risk-free securities). It has an expected return of 14% with a volatility of 20%. Currently, the risk-free rate of interest is 3.8%. Your broker suggests that you add Hannah Corporation to your portfolio. Hannah Corporation has an expected return of 20%, a volatility of 60%, and a correlation of 0 with the Natasha Fund.

1. Is your broker right?
2. You follow your broker’s advice and make a substantial investment in Hannah stock so that, considering only your risky investments, 60% is in the Natasha Fund and 40% is in Hannah stock. When you tell your finance professor about your investment, he says that you made a mistake and should reduce your investment in Hannah. Is your finance professor right?
3. You decide to follow your finance professor’s advice and reduce your exposure to Hannah. Now Hannah represents 15% of your risky portfolio, with the rest in the Natasha fund. Is this the correct amount of Hannah stock to hold?
4. Calculate the Sharpe ratio of each of the three portfolios. What portfolio weight in Hannah stock maximizes the Sharpe ratio?

There are three steps (open, action, close) required for handling files. You need to write a Python program what executes each of these three steps. Your program must include:
 Extensive comments to ensure explanation of your code (1).
 Open a file (file name must include your student number, thus filexxxxxxxx.txt). (1).
 Write the details of the five students (from Question 1 above) to a file (3).
 Close the file. (1)
 Then open the file again (1).
 Write the contents of the file to display on the screen (3).

You work for a pharmaceutical company that has developed a new drug. The patent on the drug will last 17 years. You expect that the​ drug's profits will be $2 million in its first year and that this amount will grow at a rate of 5% per year for the next 17 years. Once the patent​ expires, other pharmaceutical companies will be able to produce the same drug and competition will likely drive profits to zero. What is the present value of the new drug if the interest rate is10% per​ year?

I need to be able to:

1. Remove elements from a binary tree

2. Print them in breadth first order

Any help would appreciated.
