Answer:

The expected value is equal to 0.176

Explanation:

mean = 36

rate per day = 48

P(x; 48)= e⁻⁴⁸( 48)³⁶/36!

E(X)= 1.425 e⁻²¹ 3.347 e⁶⁰/3.72e⁴¹

E(X)= 1.425 *3.347*e⁻²/3.72

E(X)= 1.3e⁻²= 0.1759= 0.176

The probability that an event occurs in a very short time interval is proportional to the length of the interval which is a positive quantity and may be interpreted as the average number of occurrences per unit of time.

The probability that two or more events occur in such a short interval is so small that it can be neglected.

events occurring in non overlapping intervals of time are statistically independent .

c. Unions in developed nations often oppose imports from low-wage countries and advocate trade barriers to protect jobs from wha
liubo4ka [24]

Answer:

The correct answer is II. This argument is in the best interests of the people they represent.

Explanation:

Trade unions in developed countries tend to support trade restrictions, because products made in countries with lower wages are generally cheaper than those made in those developed countries. For example, a pan loaf that costs about 3 dollars in the United States, can cost about 0.75 dollars in Mexico. Therefore, import value, including tariffs, is less than that of national production. This means that, if barriers to trade are not established, many workers lose their jobs due to the fact that national production is terminated due to the possibility of importing said products.

Walter is a chemistry teacher who earns $50,000 per year, while Jesse is unemployed. Both Walter and Jesse want to go back to sc
katrin2010 [14]

Answer:

No, their economic cost of enrolling in the business program is not the same for both,

Explanation:

The explicit costs of going back to college are the same for Walter and Jesse, e.g. they might be $20,000 per year, or even $30,000 doesn't matter for this analysis. But Walter is currently working as a teacher and that means taht if he decides to go to college, his implicit costs will include the forgone salary as a teacher which is $50,000 per year. Implicit costs are opportunity costs, i.e. additional costs or benefits lost from choosing one activity or investment instead of another alternative.

Since Jesse is not working, whether she goes back to college or not will not affect her income, it will still be $0, but if Walter goes back to college he will lose his salary.

Suppose an industry earns a rate of return of 10%, which is twice as high as that of competitive industries, 5%. How much is the
sergey [27]

Answer:

Let us assume that both the industries are having an investment of $100,000

The profit of the given industry which is having 10% rate of return will be $100,000 * 10% = $10,000

The other industry which is having the Rate of return of 5% will earn a profit of $100,000 * 5% = $5000.

As the capital is just half of the revenue, it signifies that the total revenue will be $200,000 . So the same value of $10,000 will be 5% of the total revenue.  On the other hand, $5,000 would be 2.5% of total revenue.

Thus, the first stated industry will charge 2.5% more than the other industry.

Gre4nikov [31]

Answer:

a) the central bank would have to decrease the money supply which would decrease output.

Explanation:

In the case when the long run price would fall due to the reduction in the aggregate demand and there is a rise of short run aggregate supply so the central bank would have to reduce the money supply due to this it automatically reduced the output as it shows the direct relation between the money supply and the output

Therefore the correct option is a.
