Interval at 95% confidence = p+/- Z sqrt (p(1-p)/n)
Upper interval => 0.68=p+1.96 sqrt (p(1-p)/n)
Lower interval => 0.52=p-1.96 sqrt (p(1-p)/n)
Putting sqrt term to be "q"

0.68=p+1.96q
0.52=p-1.96q

Adding the two equations to solve for p (proportion of 150 adults rootng for North high school);
1.2 = 2p => p=0.6

if estimated land value is 225,000 total net operating income is 85,000 and interest on the estimated land value is 14% per year
marishachu [46]

Answer:

Residual income is $53,500

Explanation:

To compute residual income, we have to find first the required minimum return by multiplying the value of an asset by the rate of return. Afterwards, we will deduct the minimum rate of return from the total net operating income of the period.

Residual income = net operating income - (minimum rate of return x value of an asset)

• = $85,000 - ( 14% x $225,000 )

• = $85,000 - $31,500

• = $53,500 (answer)

Subsidies also distort resource allocation by encouraging excessive energy consumption, artificially promoting capital-intensive
Agata [3.3K]

Answer:

True

Explanation:

This is a negative effect of energy subsidizes. Usually governments decide to subsidize energy consumption as a way of helping low income consumers and businesses. But at the end that doesn't happen and the results are quite the opposite. Most of the subsidies are taken by higher income families, e.g. big luxury homes use a lot of electricity. Subsidies end up reinforcing inequalities and the lower income families usually pay a higher percentage of the cost of having them.

The fed increases the quantity of money. in the short run, the quantity of money demanded ______ and the nominal interest rate _
Nimfa-mama [501]

The quantity of money demanded <u>increases</u> and the nominal interest rate <u>falls.</u>

In the short run, if the Fed(Federal Reserve) increases the quantity of money, the quantity of money demanded will increase and the nominal interest rate falls.  

The quantity of the money supplied and the nominal interest rates has an inverse relation. That is, when there is a huge supply of money in a short-term, it will cause an increase in the nominal interest rate.

The nominal interest rate refers to the interest rate before adjusting to inflation or price-hike. It balances the supply and demand of money.

So when there is an increase in the supply of money ,there will be the resulting increase in the demand of money too. The total money that the population wants to hold is referred as the money demanded.

What are some of the ways in which the government is involved in the economy? what are the advantages and disadvantages of gover
ArbitrLikvidat [17]
The government can control tariffs and can limit how much can be imported into the usa.
The government can provide subsidies to certain producers, typically farmers.
The government can put a ceiling and a floor on prices as they wish. They can control the lowest and highest price a commodity can sell for.
The government can own public works such as a water company if they feel they can provide the service for a lower cost than the local competitors.
The government can decide which companies are monopolies and which companies are violating federal policies regarding trade. The government has the power to break up monopolies.
Each of these has advantages and disadvantages. For example, for farmers, when prices on their crops are too low, the government "gives" them money for their crops so they can stay in business.
A monopoly business controls the price and supply. If the monopoly is broken up, then competitors can enter the field- this can help drive down prices.
If the government can provide utility services for cheaper, that is good.
