Prepare a chart of your major expenses and check the impact of inflation by using inflation calculator and make a comparative analysis for the year 2010 and 2019? You can use the link : https://www.bankofcanada.ca/rates/related/inflation-calculator/   (Eg: A car that costs $ 5000 in 2010 will cost $5804.26 in 2019 )

• Explain the concept behind the calculator’s calculation.
• What are the major item baskets for determining Canada’s CPI? What is the weightage of each item in the item basket?

What are the trends in the national minimum wage for the UK?

You are in a boat traveling perpendicular to waves in water. The wave speed is 8.40 m/s, your speed is 6.50 m/s, and you are heading into the waves. If the wavelength of the waves is 6.70 m, how much time passes between hitting the top of one wave and the next? [This Doppler effect in water is just like that in sound; you can also calculate it from velocities and length.]

Two carts (100 g and 150 g) on an air track are separated by a compression spring. The spring is released. Represent the process with a momentum bar chart (a) with one cart as the system and (b) with both carts as the system. (c) Write expressions for all the physical quantities you can from this information. Identify your object of reference.

**Problem 3 (5 pts) - similar to Pr. 44 page 243 in text** Consider tossing **four** fair coins. There are 16 possible outcomes, e.g `HHHH,HHHT,HHTH,HTHH,THHH, ...` possible outcomes. Define `X` as the random variable “number of heads showing when four coins are tossed.” Obtain the mean and the variance of X. Simulate tossing three fair coins 10,000 times. Compute the simulated mean and variance of X. Are the simulated values within 2% of the theoretical answers?

Hint: to find the theoretical values use `dbinom (x= , size = , prob = )`

For the following reaction, KcKc = 255 at 1000 KK.
CO (g) + Cl2 (g) ⇌ COCl2 (g)CO (g) + Cl2 (g) ⇌ COCl2 (g)
A reaction mixture initially contains a COCO concentration of 0.1550 MM and a Cl2Cl2 concentration of 0.173 MM at 1000 KK.

a) What is the equilibrium concentration of COCO at 1000 KK?

b) What is the equilibrium concentration of Cl2Cl2 at 1000 KK?

c) What is the equilibrium concentration of COCl2COCl2 at 1000 KK?

Bryan followed in his father’s footsteps and entered into the carpet business. He owns and operates I Do Carpet (IDC). Bryan prefers to install carpet only, but in order to earn additional revenue, he also cleans carpets and sells carpet cleaning supplies. Compute his taxable income for the current year considering the following items:

a) IDC contracted with a homebuilder in December of last year to install carpet in 10 new homes being built. The contract price of $80,000 includes $50,000 for materials (carpet). The remaining $30,000 is for IDC’s service of installing the carpet. The contract also stated that all money was to be paid up front. The homebuilder paid IDC in full on December 28 of last year. The contract required IDC to complete the work by January 31 of this year. Bryan purchased the necessary carpet on January 2 and began working on the first home January 4. He completed the last home on January 27 of this year.

b) IDC entered into several other contracts this year and completed the work before year-end. The work cost $130,000 in materials and IDC elects to immediately deduct his supplies. Bryan billed out $240,000 but only collected $220,000 by year-end. Of the $20,000 still owed to him, Bryan wrote off $3,000 he didn’t expect to collect as a bad debt from a customer experiencing extreme financial difficulties.

c) IDC entered into a three-year contract to clean the carpets of an office building. The contract specified that IDC would clean the carpets monthly from July 1 of this year through June 30 three years hence. IDC received payment in full of $8,640 ($240 a month for 36 months) on June 30 of this year.

d) IDC sold 100 bottles of carpet stain remover this year for $5 per bottle (it collected $500). IDC sold 40 bottles on June 1 and 60 bottles on November 2. IDC had the following carpet cleaning supplies on hand for this year, and IDC has elected to use the LIFO method of accounting for inventory under a perpetual inventory system: Purchase Date Bottles Total Cost November last year 40 $120 February this year 35 $112 July this year 25 $85 August this year 40 $140 Totals 140 $457

e) On August 1 of this year, IDC needed more room for storage and paid $900 to rent a garage for 12 months.

f) On November 30 of this year, Bryan decided it was time to get his logo on the sides of his work van. IDC hired We Paint Anything, Inc. (WPA), to do the job. It paid $500 down and agreed to pay the remaining $1,500 upon completion of the job. WPA indicated it wouldn’t be able to begin the job until January 15 of next year, but the job would only take one week to complete. Due to circumstances beyond its control, WPA wasn’t able to complete the job until April 1of next year, at which time IDC paid the remaining $1,500.

g) In December, Bryan’s son, Aiden, helped him finish some carpeting jobs. IDC owed Aiden $600 (reasonable) compensation for his work. However, Aiden did not receive the payment until January of next year.

h) IDC also paid $1,000 for interest on a short-term bank loan relating to the period from November 1 of this year through March 31 of next year.

Using PYTHON. Implement the stooge sort algorithm3to sort an array/vector of integers.

Your program should be able to read inputs from a file called “data.txt” where the first value of each line is the number of integers that need to be sorted, followed by the integers

The output will be written to a file called “stooge.txt”.

Stooge sort is a “bad” recursive sorting algorithm. Given an array A, the algorithm can be defined as follows:

Step 1:

If the value at the leftmost position of the array is larger than the value at the rightmost position then swap values.

Step 2: If there are 3 or more elements in the array, then:

 Recursively call Stooge sort with the initial 2/3 of the array

 Recursively call Stooge sort with the last 2/3 of the array.

 Recursively call Stooge sort with the initial 2/3 of the array again.

Examplevalues for data.txt :

4 19 2 5 11

8 1 2 3 4 5 6 1 2

our company is considering a machine that will cost $ 6,582 at Time 0 and which can be sold after 3 years for $ 231 . To operate the machine, $ 418 must be invested at Time 0 in inventories; these funds will be recovered when the machine is retired at the end of Year 3. The machine will produce sales revenues of $ 981 /year for 3 years; variable operating costs (excluding depreciation) will be 56 percent of sales. Operating cash inflows will begin 1 year from today (at Time 1). The machine is in the 3-year MACRS class. The MACRS class has depreciation of 33% in year 1, 45% in year 2, 15% in year 3, and 7% in year 4. The company has a 30 percent tax rate, enough taxable income from other assets to enable it to get a tax refund from this project if the project's income is negative, and a 10 percent cost of capital. Inflation is zero. What are the terminal cash flows associated with ending this project?

Note, I want only the Year 3 terminal cash flows, not the year 3 operating cash flows. Show your answer to the nearest $.01 Do not use the $ symbol in your answer.
