Answers

Answer 1

At the end of the study, the mean number of back problems will be compared between the two groups.

This study is an example of a randomized controlled trial, which is a type of experimental study design that randomly assigns participants to either a treatment or a control group. By randomly assigning participants, researchers can minimize the influence of extraneous variables and ensure that any differences observed between the groups are due to the treatment and not other factors.

Random assignment to the treatment groups is important in this study to ensure that the two groups are as similar as possible at the start of the study, and to eliminate the possibility of confounding variables affecting the results. By randomly assigning participants to stand or sit, the occupational safety officer can be reasonably confident that any differences in back problems between the two groups are due to the treatment and not due to other factors.

A demand curve that is horizontal indicates that the commodity ______ while a demand curve that is vertical indicates that the commodity ________

Answers

A demand curve that is horizontal indicates that the commodity has an elastic demand, while a demand curve that is vertical indicates that the commodity has an inelastic demand.

When a demand curve is horizontal, it means that a small change in price will cause a relatively large change in the quantity demanded. This indicates that the commodity has an elastic demand. Elastic demand means that consumers are sensitive to changes in price, and that a change in price will have a significant impact on the quantity demanded.

When a demand curve is vertical, it means that a change in price will have little to no effect on the quantity demanded. This indicates that the commodity has an inelastic demand. Inelastic demand means that consumers are not very sensitive to changes in price, and that a change in price will have little impact on the quantity demanded.

III loss of profits after being sued by an employer IV loss of money because of adverse movements in currency exchange rate a. I and III b. Only III c. III and III d. All of the above

Answers

The correct answer is b. Only III. Financial risks refer to potential events or circumstances that can negatively impact an organization's financial performance or value.

Among the options provided: I. The decline in the value of a bond portfolio because of rising interest rates - This represents an interest rate risk, which is a type of financial risk. When interest rates rise, the value of existing bonds typically decreases.

II. Increased cost of raw materials - This represents a commodity price risk or input cost risk. It is related to operational or business risk rather than financial risk.

III. Loss of profits after being sued by an employer - This represents a legal risk or litigation risk. It is not specifically a financial risk, but it can have financial implications for a company if it results in financial loss or penalties.

IV. Loss of money because of adverse movements in currency exchange rate - This represents a currency exchange rate risk, which is a type of financial risk. Adverse movements in exchange rates can lead to financial losses when dealing with foreign currencies.

Since option III is not considered a financial risk, the correct answer is b. Only III.

Which of the following statements support the claim that incentives matter? Explain why or why not. 1. When income transfers to the able­bodied poor increase, the recipients will have less incentive to work. 2. An increase in the fines associated with downloading music and videos protected by copyright laws reduces the number of people engaging in this activity. 3. An increase in the number of people downloading music and videos negatively impacts the commercial production of music and videos.

Answers

Answer:

Statements supporting the claim that incentives matter

1. When income transfers to the able­-bodied poor increase, the recipients will have less incentive to work.

2. An increase in the fines associated with downloading music and videos protected by copyright laws reduces the number of people engaging in this activity.

Explanation:

It must be established ab initio that these statements are relatively correct.  Firstly, able-bodied men will only continue to be transferred income when there are no jobs available.  Once, there are jobs and the able-bodied poor can access the jobs, they would automatically be denied of the incentives.  In the second case, the incentive may be destroyed if the increase in fines outweighs the collections from the privated downloading.

Economic incentives are the things that can motivate one to make choices and behave in some ways.  These incentives may be negative or positive, i.e. they may be motivating or demotivating.  Changes in incentives will always alter people's behavior.  Assuming that the transfers to the able-bodies people are greater in value than the potential job rewards, then the incentive to work will be greatly reduced, and vice versa.

To explain this situation, Economists have developed a framework called "incentives matter" to explain why bad behavior happens.  They conclude that incentives become destructive when the payoff for such behavior is more handsome than the low odds of being caught and reprimanded or any other available option.   The framework shows that ordinary people will work out a scheme or even perpetrate fraud, just to receive the incentives they are offered, especially by governments, that are always guilty of behaving like Father Christmas.

under current gaap, using the acquisition method for a business combination, goodwill is generally defined as: group of answer choices cost of the investment less the subsidiary's book value at the beginning of the year. cost of the investment less the subsidiary's book value at the acquisition date. cost of the investment less the subsidiary's fair value at the beginning of the year. cost of the investment less the subsidiary's fair value at acquisition date.

Answers

Under current GAAP and the acquisition method, goodwill is generally defined as the cost of the investment less the subsidiary's fair value at the acquisition date. So, correct option is D.

The acquisition method is the most common approach used to account for business combinations. Under this method, the acquirer recognizes the assets and liabilities acquired at their fair values at the acquisition date, including any goodwill.

Goodwill is an intangible asset that represents the excess of the cost of an acquisition over the fair value of the net assets acquired. It reflects the value of the acquired business as a whole, including its brand name, customer relationships, and other intangible assets that are not separately identifiable.

Therefore, under the acquisition method and current GAAP, goodwill is calculated as the difference between the cost of the investment and the fair value of the net assets acquired at the acquisition date.

This calculation is important because it helps the acquirer to allocate the purchase price of the acquired business to the assets and liabilities acquired, including goodwill.

Therefore, correct option is D.

Answers

The most probable risk factor associated with the leaning of forearms on the sharp edge of a counter is getting an injury on the forearms by creating pressure on the skin.

What is a risk factor?

A risk factor is the increased possibility of having an injury or infection. It can be due to the happening of any event or the presence of any harmful object which leads to that injury or infection.

When an individual bends his/her forearm over the sharp edge of the counter, then it leads to the pressing of the skin present on the forearms against the sharp edge. There is a layer, called epidermis present on the skin which gets injured very badly due to the sharp edge and creates marks or strokes on the forearm.

Therefore, the pressure on the skin is the risk factor present when leaning the forearms on the sharp edge.

Answers

Answer: first one contributes are not taxed until the employee retires
Explanation: I hope this helps

The true statement about a 401k is Contributions are not taxed until the employee retires Option(A) is correct. No expenses are expected on the cash contributed or the speculation profit until the worker pulls out the cash, for the most part in retirement.

What does 401k means?

A 401(k) plan is a retirement reserve funds plan presented by numerous American managers that has charge benefits for the saver.

The worker who pursues a 401(k) consents to have a level of every paycheck paid straightforwardly into a venture account. The business might match part or the entirety of that commitment.

The representative will pick among various venture choices, generally common assets. With a customary 401(k), representative commitments are deducted from gross pay, meaning the cash comes from the worker's finance before personal charges have been deducted.

Subsequently, the representative's available pay is diminished by the aggregate sum of commitments for the year and can be accounted for as an expense derivation for that charge year,

Therefore Option(A) is correct.

Zack buys 40 shares of ebay at the close price of $20. 95. His broker charges him 4% of each share as a transaction fee. How much did zack spend in total to buy this stock?

Answers

The amount of money that the Jack spent in order to purchase the shares of eBay is calculated to be  $871.52.

The total amount spent by Zack to buy 40 shares of eBay can be calculated as follows:

Total cost = (Number of shares x Share price) + Transaction fees

Number of shares = 40

Share price = $20.95 per share

Transaction fee = 4% of $20.95 per share = $0.838 per share

So, the total cost for Zack to buy 40 shares of eBay can be calculated as:

Total cost = (40 shares x $20.95 per share) + (40 shares x $0.838 per share)

Total cost = $838 + $33.52 = $871.52

Therefore, Zack spent a total sum of $871.52 in order  to get 40 stocks of eBay, including the transaction fees charged by his broker.

Loan B would be made for the same amount, but for 7 percent interest for 30 years, with 2 points to be included in the closing costs. Both loans will be fully amortizing.


a. If the loan is repaid after 20 years, which loan would be the better choice?

b. If the loan is repaid after 5 years, which loan would be the better choice?

Answers

Answer:

a) loan A is a better choice

b) loan B is a better choice

Explanation:

the monthly payment of loan A = $449.66

present value of loan A = ($75,000 x 6%) + $75,000 = $79,500

the monthly payment of loan B = $498.98

present value of loan B = ($75,000 x 2%) + $75,000 = $76,500

the difference between monthly payments = $498.98 - $449.66 = $49.32

if we calculate the present value of 20 years paying $49.32 more it is:

PV = $49.32 x 139.58077 (PV annuity factor, 0.5%, 240 periods) = $6,884 which is higher than the difference

if we calculate the present value of 5 years paying $49.32 more it is:

PV = $49.32 x 51.72556 (PV annuity factor, 0.5%, 60 periods) = $2,551 which is lower than the difference

Calculate how many hours his non-salary employees will take to create a large order of 1,000 shoes. What kind of budget would Jose create?

Answers

This question is incomplete but will answer this based on what I guess you're asking.

Answer and Explanation:

Assume there are 10 employees for the small factory that makes shoes.

Let's assume each non-salary employee spends 30 minutes on each pair of shoes before it finishes, and charges $10 per hour.

1000 pairs of shoes would take 1000×0.5×10= 5000 hours(208 days and a few hours)

Total budget for non-salary employees= 5000 hrs×$10= $50000

Therefore Jose would need a $50000 budget given the variables above.
