We have a region occupied by a homogeneous isotropic dielectric with a relative
permeability of ?? = 1 and a relative permittivity of ?? = 4. In this region, the electric field has a value;
?⃑ = ?̂(-4/R^2) ?????/?????
where ?̂ is the radial unit vector, and ? is the distance from the origin. The current density ? is zero everywhere. The electric field is constant (static) in time. Point A is on the z-axis at position (? = 0, ? = 0, ? = −2 ??????); point B is on the z-axis at (? = 0, ? = 0, ? = +4 ??????) and point C is at (? = +1 ?????, ? = +1 ?????, ? = +1 ?????). The voltage at infinity is set to zero. Finally, you are given a closed contour ?1 which forms a closed circle with its center at the origin and a radius of 1 ????? in the x-y plane. Answer the following questions and state the correct units:
(a) State (in English, no equations), what is the definition of the electrostatic potential (voltage)
between two points. State what units this potential is given in terms of the following standard
units; meters, kilograms, seconds, Joules, and Coulombs.
(b) What is the value of the path integral of the electric field around closed contour ?1?
(c) If we construct a sphere with a radius of ? = 2 ??????, and place this sphere at the point
?(? = +1, ? = +1, ? = −1). Calculate the volume integral of the divergence of the electric
field intensity ∫ ? ∙ ?⃑?v over this volume. State the correct units.
(d) What is the total flux of the electric field ∮s1 ?⃑ ∙ ??⃑1 through the closed surface ?1 surrounding this volume?
(e) Is the voltage at point C greater than, less than, or equal to zero? Write down the relevant path integral and explain your reasoning.
(f) Where is the divergence of the electric field intensity ?⃑ not equal to zero?
(g) Find the exact value of ?(?) − ?(?) by sketching the x-z coordinate plane system, performing
the appropriate path integral, and showing the path taken step-by-step. No credit will be given
for any other technique of obtaining an answer.
(h) What is the curl of the magnetic field intensity ∇ × ?⃑ at the origin (? = 0, ? = 0, ? = 0)? Write down the relevant equation and explain your reasoning.
(i) What is the work that we would have to perform to move a charge of ? = −3 ???????? from point C to infinity (∞)?
(j) Where does the divergence of the magnetic flux density ?⃑⃑ not to zero?

b) What the mean and Standard Deviation (SD) of the Close column in your data set?
Mean: 1198.26
Standard Deviation: 85.39
c) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution. (5 points)
There are also 5 points for miscellaneous items like correct date range, correct mean, correct SD, etc.

On October 20, 2020, Kevin Mason, President of Tropicane Juice is reviewing the financial statements of Sunnydee, a potential acquisition candidate for the company. Tropicane is an American company, which produces and distributes juice throughout North America. It is in juice production and is interested in getting into the Canadian market. Sunnydee is a Canadian company that produces similar juice products and sells these across Canada. Tropicane is a public company and Sunnydee is a private company. Sunnydee is owned by the local area farmers and was originally started as a co-operative. Of the 1,000,000 shares outstanding, 600,000 are owned by the founder of the company, Mr. S. The rest are owned by various employees. Sunnydee has a perpetual debt with a par value of $5 million and coupon rate of 6 percent. However, interest rates have decreased and now the debt has a 4 percent yield-to-maturity. Annual before-tax before-interest operating cash flows for the year just ended were $3 million. The corporate tax rate was 20 percent. Assume perpetual operating cashflows for Sunnydee’s future cashflows. Tropicane has return on equity of 12.24%, debt-to-equity ratio of 40%, and yield to maturity of 3% on its outstanding debt.
a) What do you think is the maximum acquisition price that Mr. Mason is willing to pay for acquiring Sunnydee?
b) Compute weighted average cost of capital for Sunnydee.

In 2020, the Alnoor Company purchased from Hamoorthe right to be the sole distributor in Muscat governance of a product called Zelenex in 2021.
Alnoor reports inventory using the periodic FIFO assumption. Late in 2021, the following information is available concerning the inventory of Zelenex:
|
Beginning inventory, 1/1/2021 (10,000 units @ $30) |
$ 300,000 |
|
Purchases (40,000 units @ $30) |
1,200,000 |
|
Sales (35,000 units @ $60) |
2,100,000 |
By the end of the year, the purchase price of Zelenex had risen to $40 per unit. On December 28, 2021, three days before year-end, Alnoor is in a position to purchase 20,000 additional units of Zelenex at the $40 per unit price. Due to the increase in purchase price, Alnoor will increase the selling price in 2022 to $80 per unit. Inventory on hand before the purchase, 15,000 units, is sufficient to meet the next six months’ sales and the company does not anticipate any significant changes in purchase price during 2022.
REQUIRED:
a) Determine the effect of the purchase of the additional 20,000 units on the 2021 gross profit from the sale of Zelenex and the payment due to Hamoor? Show calculations and explanations?
b) Assume that during 2022 Alnoor Company bought 50,000 units of Zelenex with the new purchase price, and 40% of units available for sale had been sold. Calculate the gross profit for the company for the year 2022. Show calculations and explanations?

The Jaguar Bank of Indianapolis (JBI) starts operations on January 1, 2020 issuing equity amounting $50. JBI advertises an annual interest of 1% for its savings deposits, paid annually, and free checking accounts (i.e., no maintenance fee). On the first day of operations, JBI receives a total of $500 as checking deposits and $450 as savings deposits. The bank lends $750 for an annual interest rate of 5%. It purchases treasury bonds worth $150 which earns 2% per annum. JBI maintains the required reserve (10% of checking deposit balances) at the Fed and keeps the remaining liquidity in cash reserves. Federal Reserve pays no interest on JBI’s reserve account. Nor does JBI on checking accounts of its customers. JBI’s operational expenses during its first year of operations is $20 and the corporate tax rate is 25%. Shareholders of JBI receive 12% dividends.
A customer defaults a loan amounting $250. The bank loses the principal amount as well as the expected interest income but repossess a property maintained as a collateral. The property is auctioned for $200 and $100 of the proceeds are used to purchase treasury bonds. Find the following.

A researcher is studying the effects of inserting questions into
instructional material for learning. There is doubt whether these
questions would be more effective before or after the corresponding
passage. In addition, the researcher wants to know the impact of
factual and thought provoking questions. Students are randomly
assigned to one of each of the four combination: position of
question (before vs. after the passage) and type of question
(factual vs. thought provoking). After 15 hours of studying under
these conditions, the students are given a test on the content of
the instructional materials. The test scores are below. What can be
concluded with α = 0.01?
