Answer:
The answer is D. Can be used to predict future profits at different levels of activity
Explanation:
The contribution income statement is a company’s financial statement that indicates how the revenue is transformed into the net income. Income statements should help investors and creditors determine the past financial performance of the enterprise, predict future performance, and assess the capability of the business to generate future revenue streams through the reporting of income and expenses.
Answer:
True, but it rarely works well.
Explanation:
The most recent and largest failure by the International Monetary Fund (IMF) has just happened in Argentina, where the government received over $50 billion in loans that it is unable to pay. The IMF has never been successful in any country where it has helped to develop a new economic plan. Ironically, some Nobel prize winners (including Joseph Stiglitz) tell countries to do exactly the opposite to what the IMF tells them to do, and that has worked much better.
On the other hand, the World Bank has had some limited success in South American countries like Bolivia and Uruguay, specially with helping to develop new industries or expand existing ones. In Bolivia it helped to develop a new agricultural plan that improved the economy of the Santa Cruz region a lot, and it is one of its major economic successes. In Uruguay it financed new projects related to paper businesses that increased the nations GDP by almost 10%.
This is the reason why the IMF has such a bad rep while the World Bank is still seen as a valid option for financing large investment projects.
THE BEHAVIORAL INDICATIONS THE MOUSE EXPRESSES IS A TYPICAL EXAMPLE OF A "KNOCK-OUT GENE" RESEARCH.
A knockout mouse, or knock-out mouse, is a genetically modified mouse (Mus musculus) in which researchers have inactivated, or "knocked out", an existing gene by replacing it or disrupting it with an artificial piece of DNA. They are important animal models for studying the role of genes which have been sequenced but whose functions have not been determined. By causing a specific gene to be inactive in the mouse, and observing any differences from normal behaviour or physiology, researchers can infer its probable function.
Answer:
Consider the case of drawing a random sample only from cell phone exchanges instead of surveying randomly generated telephone numbers from non-cell phone exchanges.
With the passing of time, more and more people are leaning towards owning a cell phone instead of a land line.
The proportion of people in the population who use cell phones is gradually increasing when compared to non-cell phone users
Major fraction of the population now consists of cell phone users
In future there will be sharp increase in this fraction
So it will be advantageous to draw a random sample only from cell phone exchanges instead of surveying randomly generated telephone numbers from non-cell phone exchanges. It improves the chance of including more people (people who do not stay at homes during the time of survey will be contacted only though cell phones which is impossible in the case of non-cell phone users)
But there are some disadvantages. Not every person has an equal chance. People without cell phones are excluded. Cell phone users could not be contacted many times due to many reasons (absence of network coverage, power shortage, or if they were not allowed to carry their phones to work places or to some highly secured places)
