Use the Kruskal-Wallis test to determine whether there is a federalism difference among the three test preparation programs. Use = 0.05.
State the null and alternative hypotheses Reconstruction.

Reconstruction failed by most other measures: Radical Republican legislation ultimately failed to protect former slaves from white persecution and failed to engender fundamental changes to the social fabric of the South. When President Rutherford B. federalism debate that had been an issue since the 1790s almost mediately . Hayes removed federal troops from the South in 1877, former Confederate officials and slave returned to With the support of a conservative Supreme Court, these newly empowered white southern politicians passed black codes, voter qualifications, and other anti-progressive legislation to reverse the rights that blacks had gained during Radical Reconstruction. The U.S. Supreme Court bolstered this anti-progressive movement federalism  with decisions in the Slaughterhouse Cases, the Civil Rights Cases, and federalism United States v.

irinina [24]

Answer:

$200,000

Explanation:

The computation of the net revenue is shown below:

= Cash sales gross - Returns and allowances + credit sales gross - discounts + beginning balance of account receivable - ending balance of account receivable  

= $80,000 - $4,000 + $120,000 - $6,000 + $40,000 - $30,000

= $200,000

We simply first compute the net cash sales after considering the returns and allowances, and net credit sales after considering the discounts, and deduct the ending balance of account receivable

Compared to a country with an MPS of 0.05, a country with an MPS of 0.2 would have to change government expenditures by ________
const2013 [10]

Answer: Four times.

Explanation:

Based on the information given, the government expenditure multiplier in this case goes thus:

K = ∆Y/∆G = 1/1-MPC = 1/MPS

For the first country with a MPS of 0.05, K = 1/MPS = 1/0.05 = 20

For the first country with a MPS of 0.2, K = 1/MPS = 1/0.2 = 5

Therefore, 20/5 = 4.

Therefore, the answer is four times.

true or false: the profit margin is the financial gain from a sale after the costs of providing the sold product have been deduc
kotykmax [81]

The profit margin is the financial gain from a sale after the costs of providing the sold product have been deducted. Thus, the statement is true.

<h3>What is the profit margin?</h3>

Profit margin is the portion of sales that a company keeps after all costs are subtracted. It essentially displays the percentage of each dollar of sales that is kept as profit. A 15% profit margin, for instance, means that a company keeps $0.15 from every dollar of sales produced.

Comparing the firm's operations to those of a best-in-class company, maybe in a different industry, is another way to increase your profit margin. This comparison could point out several operational tweaks that could be done to raise profit margins.

g If you require an annual rate of return of 12 percent, what should be the estimate of the amount of the annual dividend which
choli [55]

Answer:

Its very simple, the required return would be 12% of the amount invested today. And this can be explained by the use of DVM (Dividend valuation Model), which is as under:

For ordinary shares  r = (Dividend after one year / Share price now)

Dividend after one year =  Required return * Share Price Now

Assuming no growth in the dividends, we can say that the required return would be 12% of the amount invested now which is the share price of the ordinary shares.

A rise in the domestic real interest rate would cause a ________ in net exports and a ________ in the exchange rate.
Kisachek [45]

A rise in the domestic real interest rate would cause a fall in net exports and a RISE  in the exchange rate.

In general, businesses and consumers spend less when interest rates are high. This is because borrowing money costs more when interest rates are high. As a result, companies frequently turn to the stock market to raise money, which can cause stock values to decline.

An increase in interest rates causes the local currency to appreciate. In comparison to domestic goods and services, import prices decline. Exports see a decline in profitability and competition. Exports decline while imports rise, reducing the net export portion of total demand and spending.
