A methods and measurements analyst needs to develop a time standard for a certain task. In a preliminary study, he observed one of his workers perform this task five times, with the following results:

Observation --- 1 --- 2 --- 3 --- 4 --- 5
Time(seconds) 84 ---76 - -80 --84 --76

How many observations should be made if the analyst wants to be 99.74 percent confident that the maximum error in the observed time is two seconds?

a. 25
b. 6
c. 49
d. 5
e. 36

Answers

Answer 1

Answer:

e. 36

Explanation:

Number of observations needed, n = (z *s / h) ^2

Where,  z = number of standard deviation needed for desired confidence level of 99.74% = 3, s = Standard Deviation of task = 4 seconds, h = maximum error in the observed time = 2 seconds.

n = (3*4/ 2) ^2

n = (12/2) ^2

n = 6^2

n = 36 observations

Thus, the number of observations needed in the task is 36 observations

Cash outflows for McKinney Publishing in 2020 included:________. $347,000 in salaries to authors. $180,000 in fees to contracted editors. $83,000 to obtain copyrights for 15 new books. $1.3 million to purchase a new printing warehouse. $560,000 to upgrade current printing equipment. How much of these cash outflows will McKinney Enterprises expense?

Answers

Answer: $527,000

Explanation:

Salaries to authors = $347,000

Fees to contracted editors = $180,000

Copyrights obtained = $83,000

Purchase of a new printing warehouse = 1.3 million

Upgrade of current printing equipment = $560,000

McKinney Enterprises expense will be:

= Salaries to authors + Fees to contracted editors

= $347,000 + $180,000

= $527,000

Discuss about Financial System and its impact on the strategic Financial Management

Answers

Answer:

The modern Financial System is based on a central bank that controls the monetary base (but not the money supply), and in fractional reserve banking. The implicaton of this, is that banks loan out some of the money that they obtain as deposits, and in this process they create money.

Explanation:

The Financial System is influenced by this process of money creation, because when the money that circulates in the economy (the money supply) changes, interest rates also change.

Interest rates are the price of investment, and the most important indicator that a financial manager has to take into account when making a financing decision.

Financial managers must also take into account the different types of financial institutions that exist, from hedge funds, to commercial banks, to cooperatives, and the different types of securities, from stocks, to bonds, to derivatives and futures.

An increase in income:________. A. changes relative prices of goods the consumer buys. B. shifts the budget constraint outward. C. shifts the budget constraint inward. D. leads to the substitution effect.

Answers

Answer: B. shifts the budget constraint outward

Explanation:

An increase in the income of a consumer will bring about an outward shift of the budget constraint. This is because when the income of a consumer rises, such consumer can buy more goods and services.

Also, a decrease in income will result into an inward shift of the budget constraint. This is because lesser goods are purchased.

Discuss how structural dimensions of the firm, including formalization, standardization, and centralization, can affect the firm’s propensity to innovate and its effectiveness at innovation

Answers

Explanation:

A company's organizational structure can be defined as the organization of the company's activities so that it operates more efficiently and effectively and achieves its objectives and goals.

Therefore, the structural dimensions of a company including formalization, standardization and centralization will directly influence the innovation of an organization in relation to several variables such as its internal environment, processes, products and services, as there are organizational structures that are more focused on innovation than others, such as the horizontal structure in relation to the vertical, since the vertical structure is the most rigid and with a higher hierarchy, while in the horizontal structure there is greater autonomy of employees and greater participation in the decision-making process, which is a more flexible environment open to innovation.

The price of TSC stock will be either $42 or $46 at the end of the year. Currently, T-bills yield 4.1 percent and TSC sells for $43 a share. What is the per share value of a one-year TSC call option if the exercise price is $45 per share?

a. $1.03
b. $.66
c. $.72
d. $.81
e. $0

Answers

Answer:

b. $.66

Explanation:

The computation of the per share value for the one year is

Given that

Current Price = $43

Possible Prices = $42 and $46

Now

u = [($46 - $43) ÷ $43] + 1

= 1.06977

And

d = 1 - [($42 - $43) ÷ $43]

= 0.9767

And,

Risk-Free Rate = T-Bill Rate = Rf = 4.1 %

Now the up move price probability is

= [(1 + Rf) - d] ÷ [u - d]

= [(1.041) - 0.9767] ÷ [1.06977 - 0.9767]

= 0.69088

And,  

Exercise Price = $ 45

Now

If the Price is $42, so Payoff = $0

And

if the Price is $46, so Payoff =is

= ($46 - $45)

= $1

Finally the call price is

= [0.69088 × 1 + (1 - 0.69088) × 0] ÷ 1.041

= $0.66367

= $0.66

Crane Company sells two types of computer hard drives. The sales mix is 30% (Q-Drive) and 70% (Q-Drive Plus). Q-Drive has variable costs per unit of $30 and a selling price of $90. Q-Drive Plus has variable costs per unit of $45 and a selling price of $135. Crane’s fixed costs are $486000. How many units of Q-Drive would be sold at the break-even point?

Answers

Answer:

1,800 units

Explanation:

With regards to the above, we need to find first the contribution margin of Q drive.

Contribution margin of Q drive = Selling price - Variable costs per unit

= $90 - $30

= $60

We will also find contribution margin of Q drive plus

Contribution margin of Q drive plus = Selling price - Variable costs per unit

= $135 - $45

= $90

Therefore, the combine contribution margin for both drive

= 30% × $60 + 70% × $90

= $18 + $63

= $81

The next step is to find the total break even point

= Crane company's fixed costs / Combined contribution margin

= $486,000 / $81

= 6,000 units

Furthermore, it means that Q drive would be sold at the break even point = Total break even point × Sales mix

= 6,000 × 30%

= 1,800 units

Total fixed costs for Diamond Enterprises are $800,000. Total costs, including both fixed and variable, are $890,000 if 120,000 units are produced. What would be the fixed cost per unit at 200,000 units?a) $4.00 per unitb) $7.42 per unitc) $4.45 per unitd) $0.45 per unit

Answers

Answer:

a. $4.00 per unit

Explanation:

Variable costs are those costs that varies with output level e.g labor cost, while fixed costs are those costs that do not change irrespective of output level. eg rent.

Given that ,

Total cost = $890,000

Total fixed cost = $800,000

Variable cost = Total cost - Total fixed cost

Variable cost = $890,000 - $800,000 = $90,000

Number of units = 200,000

Fixed cost per unit = Total fixed cost / Number of units

Fixed cost per unit = $800,000 / 200,000 = $4 per unit

Equipment that was purchased for $900,000 has a current book value of $450,000. Assume a capital gains tax rate of 28%. Compute the net tax payment or savings if you sell the equipment for $636,400.

Answers

Answer:

there is an increase in taxes of $52,192

Explanation:

The computation of the net payment or saving is shown below:

Given that

Book value = $450,000

Sale value = $636,400

since the sales value is more than the book value so here the capital profit is there

Therefore capital profit would be

= $636,400 - $450,000

= $186,400

Now tax would be

= $186,400 × 28%

= $52,192

So there is an increase in taxes of $52,192

What is the firm's WACC if the tax rate is 40 percent?

a. 8.79%
b. 8.49%
c. 9.93%
d. 8.33%
e. 9.52%

Answers

Answer:

a. 8.79%

Explanation:

WACC = Weight of debt * Pretax cost * (1 - Tax) + Weight of Equity * Cost of Equity

Value of Equity = 10,700 * $63 = $674,100

Value of debt = 320 * $1000 * 93.6% = $299,520

Weight of Debt = $299,520/($299,520 + $674,000) = 30.76%

Weight of Equity = $674,000/($299,520 + $674,000) = 69.24%

WACC = 30.76% * 5.89% * (1 - 40%) + 69.24% * 11.13%

WACC = 30.76% * 5.89% * 0.60 +  69.24% * 11.13%

WACC = 0.010870584 + 0.07706412

WACC = 0.087934704

WACC = 8.79%
