Suppose you have been building a model using the k-means clustering algorithm and you keep finding that a certain variable is essentially ignored by the model (in other words, the variable is very similarly distributed across all clusters). Describe a method that can be used to exaggerate or minimize the impact of a variable when using k-means clustering. Why does this method work?

Cary and Elle Bronson had been married for 15 years when trouble arose in their marriage. Cary’s long hours of working had taken a toll on it; he was rarely around even for family functions. The last straw came when Elle found lipstick on the collar of Cary’s shirt and the unmistakable scent of a very expensive woman’s perfume; this wasn’t the first time she had noticed the telltale signs of what appeared to be a clandes¬tine affair. The next day, Elle visited an attorney to begin divorce proceedings. After some small talk, the attorney, Mark Smithson, asked Elle about the major assets accu¬mulated during the marriage. “Oh, there are the cars—a Jeep Cherokee, a Chevy Suburban, and a Bentley,” she answered. “A Bentley?” he queried, somewhat surprised. “Yes,” said Elle. “Our restaurant, The Roasted Duck, has done very well over the years. We began the business with almost nothing and both worked there until Karen, our second child, was born. At that point, I became a stay-at-home mom and left every¬thing to Cary.” “I’ve eaten at The Roasted Duck—the food is excellent,” Mark said. “Thank you,” replied Elle. “Is this the only source of income for you and your husband, Mrs. Bronson?” he asked. “Yes, other than some interest and dividends,” she answered. She and the lawyer discussed other matters pertaining to the divorce. He told Elle that he would obtain information from Cary’s attorney so that an equitable division of assets could occur and the issue of the custody of their children would be settled. Two weeks later, Elle received a call from Mark. Through the discovery process, Cary’s attorney had submitted a valuation of the restaurant that seemed unusually low and had not listed any other assets that could account for the house and vehicles that the Bron¬sons had acquired and the private education that they had provided for their children. “That can’t be right!” Elle exclaimed. “Well, it certainly doesn’t look right,” Mark said, “I’ll look into this some more and let you know what I find.” After he hung up the phone, Mark called Cary’s attorney. “This value placed on the restaurant doesn’t make any sense. What’s your take on this?” After a short pause, the attorney replied, “Cary told me that the restaurant business is not doing well and, thus, the value has declined.” After Mark hung up the phone, he pondered the situation: There must be an answer to this mystery. One thing’s for sure; if Cary isn’t telling the truth, he might as well change the name of his restaurant to The Cooked Goose.

What evidence (i.e., physical, documentary, and observational) could be collected to determine whether the valuation is correct?

How could you go about collecting this evidence?

Assume for a moment that the valuation is correct.

Give a breakdown on reduction and oxidation with relation to alcohols and the possible reagents that are used to do so.

Provided that c1, c2 and c3 are of appropriate ranges. Use transform() algorithm so that it copies the larger of the corresponding elements from c1 and c2 to c3. That is, if

   c1 = {1, 2, 3, 4, 5} and   c2 = {5, 4, 3, 2, 1}

   then c3 should become c3={5, 4, 3, 4, 5}

Investment A

You are 25 years old, having just started working. You are considering a retirement plan for a retirement at the age of 65. You want to be able to withdraw $73,000 from your savings account on each birthday for 20 years following your retirement at the age of 65. Your first withdrawal will be on your 66th birthday. To achieve your goal, you intend to make equal annual deposits in a pension scheme which offers 7% interest per year.

According to the Investment A, you expect a lump sum of $ 100,000 from a family inheritance fund that you will receive on your 50th birthday. You will put this fund into the retirement savings account. Furthermore, you have invested in a portfolio what will be giving you $ 1,300 per year (from age 25 through age 65) which are to be added the retirement savings account as well.

If you begin making these deposits on your 25nd birthday and continue to make deposits until you are 65 (your last deposit will be made on your 65th birthday), what is the amount you are required to deposit annually to be able to make the desired withdrawals at retirement?

Investment B

Here you still have the same retirement plan in mind, in other words you want to be able to withdraw $73,000 from your savings account on each birthday for 20 years following your retirement at the age of 65. However, the investment criteria are different:

You have invested in a business which gives an annual net profit of $ 2,300 per year.
Furthermore, your employer will contribute $ 550 to the account per year as part of the company’s

profit-sharing plan starting from age 45 to 65. What amount must you deposit annually now to be able to make the desired withdrawals at retirement? Which investment will you choose and why?

HW2: Interest Rate Parity with bid-ask spreads

Suppose:

 Spot rate St = $1.5080 - $1.5095 / £

 Six month Forward rate Ft,t+6 = $1.5280 – 1.5292/£

 Interest rate in US = 4.6% – 4.8%

 Interest rate in UK = 3.0% – 3.3%

With bid-ask rates and borrowing-lending rates, is arbitrage profit possible if you start with $1 million in part (a) and £ 1 million in part (b) ? Do it both ways :

(a) borrow $ 1 million in US and invest overseas and

(b) borrow £ 1 million in UK and invest in US.

C++ Lexicographical Sorting

Given a file of unsorted words with mixed case: read the entries in the file and sort those words lexicographically. The program should then prompt the user for an index, and display the word at that index. Since you must store the entire list in an array, you will need to know the length. The "List of 1000 Mixed Case Words" contains 1000 words.

You are guaranteed that the words in the array are unique, so you don't have to worry about the order of, say, "bat" and "Bat."

For example, if the array contains ten words and the contents are

cat Rat bat Mat SAT Vat Hat pat TAT eat

after sorting, the word at index 6 is Rat

You are encouraged to use this data to test your program.

This is a c++ code. Write a series of assignment statements (complete executable code) that find the first three positions of the string “and” in a string variable sentence. The positions should be stored in int variables called first, second and third. You may declare additional variables if necessary. The contents of sentence should remain unchanged. The sentence can be completely random.

Im having a large problem with this. It's a simple c++ code, but im unable to get it. Thank you.
