There are many ongoing research projects that have been conducted that have traced the
individual pathways of nerves in the brain (where they start, where they end, and the path
taken). Considering the analogy of the nerves as highways, is this useful or not? Why?

Assume a mutual fund owns 2,500 shares of Goldman Sachs, trading at $66.25, 1,500 shares of Amazon, currently trading at $61.75, and 2,000 shares of Apple, trading at $18.50 on day 1. The mutual fund has no liabilities and 15,000 shares outstanding held by investors.

a. What is the NAV of the fund?

b. Calculate the change in the NAV of the fund if the next day Goldman Sachs’ shares increase to $69, Amazon’s shares increase to $65, and Pfizer’s shares decrease to $15.50.

c. Assume that on Day 1, 750 additional investors buy one share each of the mutual fund at the NAV obtained in part a) equal to $Y. This means that the fund manager has 750 * Y additional funds to invest. The fund manager decides to use these additional funds to buy additional shares in Amazon. Calculate next day’s NAV given the same rise in share values as calculated in part b.

Question 1

2C2 H4 + 02 -- > 2C2 H40

Ethylene oxide is produced by the catalytic oxidation of ethylene. The feed into the reactor contains 1700 g/min ethylene and 3700 moles/min air.

a.      What is the limiting reactant?

b.      What is the extent of reaction if only 81% of the limiting reactant is converted to the product?

c.       What is the molar composition of the product stream?

Question 2

Air at 95 °F can hold maximum of 3.52 wt% water, defined as 100% humidity at 95°F. On a hot humid day the temperature is 95°F and the air contains 3.2 wt% water (90.9 % humidity). The air cooled to 68 °F because air at 68 °F can hold a maxium of 1.44 wt% water ( i.e 100% humidity at 68 °F), water condenses from the air. Hot humid air (95°F, 90.9% humidity) flows into a cooler at a rate of 154 .0 Kg/min. Calculate the flow rate of 2 streams leaving the cooler:

a.      Air at 68°F and 1OO% humidity (stream 1: air leaving the cooling unit)

b.      Water condensed from the air (stream 2: water leaving the cooling unit)

c.       What is the degree of freedom for the cooling unit

Question 3

A mixture of organic solvents containing 45.0 mole o/o xylene, 25.0o/o toluene, and the balance benzene (X) is fed to a distillation column. The bottom product contains 98.0 mole% xylene and no benzene, and 96.0°/o of the xylene in the feed is recovered in this stream. The overhead product is fed to a second distillation column. The overhead product from the second column contains 97.0o/o of the benzene in the feed to this column. The composition of this stream i 94.0 mole% benzene and the balance toulene.

a)      Draw and label a flow chart for the process

b)      Calculate the unknown process variables

c)      The percentage of the benzene in the process feed (i.e. the feed to the first column) that emerge ,in the overhead product from the second column.

d)      The percentage of toluene in the process feed that emerges in the bottom product from the second column.

If anybody can solve these questions I would rally appreciate it.

The following information is available to reconcile Branch Company’s book balance of cash with its bank statement cash balance as of July 31, 2017.

1. On July 31, the company’s Cash account has a $24,752 debit balance, but its July bank statement shows a $27,080 cash balance.
2. Check No. 3031 for $1,520 and Check No. 3040 for $752 were outstanding on the June 30 bank reconciliation. Check No. 3040 is listed with the July canceled checks, but Check No. 3031 is not. Also, Check No. 3065 for $536 and Check No. 3069 for $2,288, both written in July, are not among the canceled checks on the July 31 statement.
3. In comparing the canceled checks on the bank statement with the entries in the accounting records, it is found that Check No. 3056 for July rent expense was correctly written and drawn for $1,280 but was erroneously entered in the accounting records as $1,270.
4. The July bank statement shows the bank collected $7,500 cash on a noninterest-bearing note for Branch, deducted a $38 collection expense, and credited the remainder to its account. Branch had not recorded this event before receiving the statement.
5. The bank statement shows an $805 charge for a $795 NSF check plus a $10 NSF charge. The check had been received from a customer, Evan Shaw. Branch has not yet recorded this check as NSF.
6. The July statement shows a $11 bank service charge. It has not yet been recorded in miscellaneous expenses because no previous notification had been received.
7. Branch’s July 31 daily cash receipts of $8,652 were placed in the bank’s night depository on that date but do not appear on the July 31 bank statement.

Required:

1. Prepare the bank reconciliation for this company as of July 31, 2017.

2. Prepare the journal entries necessary to bring the company’s book balance of cash into conformity with the reconciled cash balance as of July 31, 2017. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

A block is attached to the top of a spring that stands vertically on a table. The spring stiffness is 49 N/m, its relaxed length is 27 cm, and the mass of the block is 300 g. The block is oscillating up and down as the spring stretches and compresses. At a particular time you observe that the velocity of the block is <0, 0.0877, 0> m/s and the position of the block is <0, 0.0798, 0> m relative to an origin at the base of the spring. Using a time step of 0.1 s, determine the position of the block 0.2 s later. The correct answer is .373651. How was this answer found?

How does accounting for a nongovernmental not-for-profit organization differ from accounting for a for-profit corporation? Choose a not-for-profit, review its financial statements, and explain the items that you find that are different from what you would see in the financial statements of a for-profit corporation.

• Write a function power(x,i) that takes an int i and a float (i.e. real number) x and returns xi, do not use Python’s in-built power function x**i , instead write a loop to do so using only multiplication.
• Now do use the power function x**i to write a second function unit_test(y) that tests whether your first function is working correctly or not.  
• Does power(x,i) work for any value of x and i ? For which values x and i does it throw an error? What happens if the input variables are letters instead of a float and an int?
• Write a new function power_2(x,i)so that instead of throwing an error, the function prints a message that explains what went wrong in each case?  

Never forget that even small effects can be statistically significant if the samples are large. To illustrate this fact, consider a sample of 129 small businesses. During a three-year period, 14 of the 100 headed by men and 5 of the 29 headed by women failed.

(a) Find the proportions of failures for businesses headed by women and businesses headed by men. These sample proportions are quite close to each other. Give the P-value for the test of the hypothesis that the same proportion of women's and men's businesses fail. (Use the two-sided alternative). What can we conclude (Use α=0.05α=0.05)?
The P-value was _______

(b) Now suppose that the same sample proportion came from a sample 30 times as large. That is, 150 out of 870 businesses headed by women and 420 out of 3000 businesses headed by men fail. Verify that the proportions of failures are exactly the same as in part (a). Repeat the test for the new data. What can we conclude?

The P-value was _______

(c) It is wise to use a confidence interval to estimate the size of an effect rather than just giving a P-value. Give 95% confidence intervals for the difference between proportions of men's and women's businesses (men minus women) that fail for the settings of both (a) and (b). (Be sure to check that the conditions are met. If the conditions aren't met for one of the intervals, use the same type of interval for both)

Interval for smaller samples: _____ to _____
Interval for larger samples: _____ to _____

1. Cost and purchase price are the two different measurements companies use to evaluate the purchasing performance. What is the benefit of developing performance measures that focus on cost versus purchase price? If the cost is a better performance measurement than cost, should purchase price be used as a performance measure at all? Why or why not?

2. What is your understanding of the difference between effectiveness and efficiency measures? Are these two measurements independent from each other? When should a firm focus on purchasing effectiveness measures? When should a firm focus on purchasing efficiency measures?
