Answer:

True

Explanation:

The work of software developers is quite tough and confusing that is why the system of language was created to help them in their work. The system of language is known as a unified modelling language, it uses various diagrams to help them in solving various complex problems. This language provides a standard way to visualise the concepts that is why it is a logical structure of a database system.

On September 1, 2015, Select Company borrowed $600,000 from a bank and signed a 12%, six-month note payable, with interest on th

notsponge [240]

Answer:

B. $624,000

Explanation:

Calculation to determine The total amount of the current liability (including interest payable) for this loan that appears in Select Company's balance sheet at December 31, 2015

Current liability=$600,000 + ($600,000 *12% *4/12)

Current liability=$600,000 + $24,000

Current liability = $624,000

(September 1 2015 to December 31 2015=4 months)

Therefore The total amount of the current liability (including interest payable) for this loan that appears in Select Company's balance sheet at December 31, 2015 is $624,000

The following two graphs show the markets for smartphones in Sweden and Norway. Use the graphs to answer the questions that foll

zalisa [80]

Answer:

Assume there are no transportation costs. With trade, the price of $22.5 brings about balance in exports and imports. At this price, 600 smartphones are traded. With trade, Sweden produces 900 smartphones and consumes 300 smartphones, and Norway produces 300 smartphones and consumes 900 smartphones.

Now suppose the per-unit transportation cost from Sweden to Norway is $5. With trade, the transportation cost changes the price of smartphones in Sweden to $25 and in Norway to $25. Sweden will produce 800 smartphones and consume 400 smartphones, thus exporting 400 smartphones. Norway will produce 400 smartphones and consume 800 smartphones, thus importing 400 smartphones.

Explanation:

With no transportation costs, Sweden shall export smartphones and Norway shall import smartphones because the market price is lower in Sweden than in Norway.

The demand and supply functions for smartphones in Sweden, derived from the given values, are:

$Q_{D} = 1200 - 40P\\$

$Q_{S} = 40P$

The export supply (ES) equation is:

$ES = Q_{S} - Q_{D}$

ES = 40P - (1200 - 40P)

ES = 80P - 1200

The demand and supply functions for smartphones in Norway, derived from the given values, are:

$Q_{D} = 1800 - 40P$

$Q_{S} = 40P - 600$

The import demand (ID) equation is:

$ID = Q_{D} - Q_{S}$

ID = 1800 - 40P - (40P - 600)

ID = 2400 - 80P

The equilibrium price and quantity traded is determined where ES = ID.

80P - 1200 = 2400 - 80P

This simplifies to P = 22.5

Q = 2400 - 80(22.5) = 600

Next, a transaction cost of $5 per unit is imposed from Sweden to Norway. This changes the ES function as follows.

New ES = 80(P - 5) - 1200

New ES = 80P - 1600

The new equilibrium is where New ES = MD.

80P - 1600 = 2400 - 80P

This simplifies to P = 25

Q = 80(25) - 1600 = 400

Identify at least one type of firm that might exhibit low correlations of returns with the overall stock market? explain why the

svlad2 [7]

<span>One firm that is historically low and deals with negatively correlated stock markets is Gold Extraction Companies. They are have very low correction with overall stock markets. The basic reason for this low correlation is that, as the stock market become bearish, investor sentiment becomes weak, due to which most of the investors withdraw their money from stock market. Now once investor has withdrawn the money from stock market , they search on safe investments which will provide them good reruns, Gold is one of the investment which is relatively safe and provide high returns. Thus withdrawn money from the share market is invested in gold by investors. Thus Gold prices and companies related to extraction of gold have very less correlation to the gold.</span>

Leona [35]

Answer: it can produce that good using fewer resources than its trading partner

Explanation:

A country has an absolute advantage in the production of a good when such country can produce the good using fewer resources than another country.

Absolute advantage can be due to the natural endowment of a country. For example, let's say Japan uses 2 hours in producing a good while Brazil uses 5 hours in producing such good. Then, it can be deduced that Japan has an absolute advantage over Brazil.
