1. Let $M$ be a left $R$-module. If $N$ is a submodule of $M$ and $$ \text{ann}_R(N) = \{r \in R : r \cdot n = 0 \text{ for all } n \in N\}, $$ show that $\text{ann}_R(N)$ is an ideal of $R$. [10 Marks]

undefined Question # 1 This problem concerns the Min-max normalization algorithm which is one of the most common ways to normalize data. Your task is to write a python program that include normalize function. This function receives a list of values, then it will normalize it by: The minimum value of the list gets transformed into a 0. The maximum value gets transformed into a 1. And every other value gets transformed into a decimal between 0 and 1 using the following formula. value - min max-min (3020) For example, if the minimum value of the list was 20, and the maximum value was 40, then value 30 would be transformed to about 0.5 since it is (4020) You should provide the following functions: def normalize(): Receive a list of values, and return a new normalized list. def main Open and read values from a text file data. txt and fill it in a list. The values of list normalize by calling the function normalize Print the values of the list after and before normalization. Note : It is not allowed to use external library to solve this question. No printing from the normalize function Assume that the file has unique distinct valid values If the input file does not exit, display the following message input file is not found Sample Run Before normalization: [70,90,78,20,5,10,6] After normalization: [.75,1,.85,.125,.5,,.625]

Case A: R, R Case B: 2R, 2R Case C: 3R, R 43. The figure shows three cases where two spheres are touching and attract each other with the gravitational force. The radii of the spheres in each case are shown. All of the spheres are made of material with the same density. Which of the following correctly ranks these cases based on the gravitational force between the spheres? (A) (A = B) > C (B) A > C > B (C) B > C > A (D) C > (A = B) 44. On Earth, when a box slides across a horizontal board, the board exerts a frictional force of magnitude F_0 on the box. The board and the box are moved to a planet with twice the radius but one-third the mass of Earth. When the box slides across the board, the frictional force exerted by the board on the box is now (A) 1/12 F_0 (B) 1/6 F_0 (C) 2/3 F_0 (D) F_0

F303 In-Class Exercise 1 - Due by 11:59pm February 11 Two siblings, Mary and John, have very different approaches to life. Mary has never met a challenge she wouldn't take, John avoids risk at all costs. Both have good jobs with great benefits, and both are about to receive an inheritance of $85,000. As their financial advisor, you expect Mary to want an exceedingly risky investment, John to want a very safe investment, possibly just a low-yield FDIC-insured savings account. You know that neither strategy makes sense. You decide to step in and offer some financial advice. Given the siblings' ages and financial conditions, you plan to suggest equity investments. You consider suggesting the stock of Pat's Perfect Pet Phood. It is currently selling for $60 with an annual dividend of $1.50 per share, and has a lot of potential due to the recent spate of pet adoptions. The margin requirement set by the Federal Reserve is 60%, and brokerage firms are charging 7% on funds used to purchase stock on margin. While commissions vary among brokers, you decide that $70 for a 100-share purchase or sale is a reasonable amount to use for illustrative purposes. Currently, commercial banks are paying 3% on savings accounts. 1. What is the percentage return earned by John if he acquires 100 shares, holds the stock for a year, and sells the stock for $80? 2. What is the percentage return earned by Mary if she acquires 100 shares on margin, holds the stock for a year, and sells the stock for $80? What advantage does buying stock on margin offer Mary? 3. What would be the percentage returns earned by each sibling if the sale prices had been $50 or $100? 4. DISCUSSION QUESTION: What would be the impact on the siblings' returns if the rate of interest charged by the broker increases to 10 percent? 5. If the maintenance margin requirement were 30 percent and the price of the stock declined to $50, what impact would that have on each sibling's position? At what price of the stock would they receive a margin call? 6. DISCUSSION QUESTION: Why would buying the stock be more advantageous to both siblings than the alternatives you anticipate them to select?
