Answer:

The correct answer is letter "A": nonequivalent group.

Explanation:

While conducting studies, nonequivalent groups are those where the target audience is not selected randomly. Instead, the participants are chosen generating another group represented by all those individuals who match the research criteria but, because of a reason, were not selected.

<em>There are different types of nonequivalent groups such as posttest only nonequivalent groups or pretest-posttest nonequivalent groups, for instance.</em>

<u>Sole proprietorship:</u> A company that has only one person and works for its own benefit. In almost all the world there are a large number of sole proprietorships which are usually small companies, the most common being for example a personal teacher, a bicycle workshop, etc.

Advantage:

- The owner receives all profits and profits.

- Independence

Disadvantages:

- There is unlimited liability so that all income can be used to pay debts.

- The owner performs several activities.

<u>Company</u>: company that has two or more people. In general, partnership companies are larger than sole proprietorships. The most common companies in society are finance and insurance.

Advantage:

- Raises more funds than sole proprietorship.

- Greater intelligence and administrative ability.

Disadvantages:

- The company dissolves when a partner dies.

- Difficulty to liquidate or transfer the company.

Advantage:

- They have a limited liability, they don't lose more money than they invested.

- The company has a long life.

Disadvantages:

- Higher organizational costs than in other business forms since they need to hire staff.

- Subject to greater government regulation.

Chuck offers $240,000 for a house. The seller turns down the offer but says she will sell the house for $260,000. However, Chuck
qaws [65]

Answer:

Chuck must be less than $260,000

Explanation:

The economic decision rule is: Do it if that marginal benefit exceeds the marginal cost and Since Chuck was unwilling to purchase the house at $260,000, we can deduce that the marginal benefit of purchasing the house must be less than $260,000 due to the fact that the seller turns down the offer but says she will sell the house for $260,000.

Robert Necco and Nelson Packard are economists at Economic Research Associates. ERA asks Necco and Packard for their opinions ab
Lorico [155]

Answer: B) Correct Incorrect

Explanation:

Whilst it was generally believed at some point that raising taxes and Government Spending by the same amount would have no effect, research has disproven this thought.

This is because it was shown that an increase in Government Spending leads to a larger increase in GDP than an increase in taxes reduces it.

This is because when the Government spends money, the Multiplier effect of Government Spending is always 1 more than that of the Taxes therefore raising taxes and spending by the same amounts still increases the Real GDP because Government Spending will create more income than taxes will take.

Necco is right, Packard is wrong.

Cox Co. accounts for its inventory using the LIFO cost method. An inventory loss from a permanent market decline of $360,000 occ
kirill115 [55]

Answer:

$360,000

Explanation:

Last in first out (LIFO) is a method used in inventory where the cost of most recently purchased goods is the one to be expensed first. Also current losses are the first to be reported.

An inventory loss incurred in a quarter must not be deferred, but recorded as items within an interim must be reported in the same period they were incurred, unless it can be redeemed before the end of the fiscal year. It is not considered a temporary item.

The loss reported in May will be reported for that quarter in June.

You found your dream house. It will cost you $300000 and you will put down $30000 as a down payment. For the rest you get a 30-y
Andrews [41]

Answer:

$1,282.80

Explanation:

The PMT formula is used for this question. The attachment is shown below:

The NPER shows the time period

Given that,  

Present value = $300,000 - $30000 = $270,000

Future value = $0

Rate of interest = 4% ÷ 12 months = 0.33%

NPER = 30 years × 12 months = 360 months

The formula is shown below:

= PMT(Rate;NPER;-PV;FV;type)

The present value come in negative

So, after solving this, the answer is $1,282.80
