the expected return of a portfolio of risky securities a) is a weighted average of the securities' returns. b) is the sum of the securities' returns.

Answers

Answer 1

The expected return of a portfolio of risky securities is a weighted average of the securities' returns. The statement "the expected return of a portfolio of risky securities is a weighted average of the securities' returns" is correct and is known as the expected portfolio return.

A portfolio is a combination of different types of assets, such as stocks, bonds, and real estate, that are held by an individual or an organization. The expected portfolio return is calculated as the weighted average of the returns of each asset in the portfolio, with the weights determined by the proportion of each asset's value in the portfolio. This is based on the assumption that the return on each asset is normally distributed, which allows for the calculation of the expected value of the returns of the portfolio.

Content Loaded The expected return of a portfolio of risky securities is not the sum of the securities' returns. Instead, it is calculated by multiplying the expected return of each security by its weight in the portfolio and then adding up these products. In this way, the expected return of a portfolio takes into account the diversification of assets and the risk of each asset. The expected return is a useful tool for investors because it helps them to assess the potential return of a portfolio and to compare different portfolios based on their expected returns.

Answers

The Malaysian Tin mining industry collapsed due to many reasons. Some of them are- competition from other countries, lower demand ,  inadequate technology,  environmental concerns and Government policies.

The Malaysian tin mining industry collapsed due to several factors that contributed to the economic downfall of the industry.

1) Competition from other countries: The global tin market faced stiff competition from other countries like Brazil, Indonesia, Bolivia, and Thailand. These countries had abundant tin reserves, and their mining processes were more efficient than those of Malaysia, making it challenging for Malaysia to compete.

2) Lower demand: The demand for tin had reduced globally due to the development of substitute materials like aluminum, which had similar properties to tin but was cheaper and lighter.

3)  Inadequate technology: The Malaysian tin mining industry relied on old and inefficient methods of mining that consumed too much time and resources. Moreover, the industry was characterized by widespread corruption and low productivity, which further reduced the competitiveness of Malaysia's tin production.

4) Environmental concerns: The mining industry in Malaysia had severe environmental consequences, which led to public outcry, forcing the government to impose strict environmental regulations. The regulations, coupled with the high cost of compliance, made it difficult for the mining industry to operate, leading to a decline in production.

5) Government policies: The Malaysian government had over-regulated the mining industry, which stifled innovation and productivity.

Moreover, government policies were inconsistent, and there was a lack of transparency in the regulatory framework. This led to a lack of investor confidence, making it difficult for the industry to attract investments and expand.

Overall, the combination of  factors like competition from other countries, lower demand ,  inadequate technology,  environmental concerns and Government policies led to the collapse of the Malaysian tin mining industry, resulting in significant economic losses for the country.

why aren't volcanoes associated with continent-continent convergence?

Answers

Volcanoes are not commonly associated with continent-continent convergence because this type of tectonic boundary typically involves the collision and uplift of continental crust, rather than volcanic activity.

During continent-continent convergence, two continental plates collide, creating immense compressional forces. As the plates collide, the continental crust becomes highly deformed and uplifted, resulting in the formation of mountain ranges, such as the Himalayas. This process is primarily characterized by intense folding, faulting, and crustal thickening.

Volcanic activity, on the other hand, is commonly associated with other tectonic boundaries, such as subduction zones or divergent plate boundaries. Subduction zones occur when one tectonic plate is forced beneath another, leading to the formation of volcanoes due to the melting of the subducted plate and the subsequent rise of magma. Divergent plate boundaries, where plates move away from each other, also give rise to volcanic activity as magma rises to fill the gap created by the spreading plates.

In continent-continent convergence, the collision and compression of continental crust do not typically generate the necessary conditions for the formation of volcanic activity. Instead, the focus is on the deformation and uplift of the crust, resulting in mountain building rather than volcanic eruptions.

The factor that seems most important in influencing how well children adjust to divorce over time is:

Answers

Divorce is a stressful life event for both parents and children. There is no one-size-fits-all approach to dealing with the emotional, psychological, and social consequences of divorce. The way children adjust to divorce over time varies widely depending on the age, gender, personality, and life circumstances of each child.

However, research suggests that the factor that seems most important in influencing how well children adjust to divorce over time is the quality of the parent-child relationship. Researchers have found that children who maintain close, supportive, and consistent relationships with their non-custodial parent tend to adjust better to divorce than children who have little or no contact with their non-custodial parent. This is because non-custodial parents provide emotional, financial, and social support to children, which helps them cope with the changes and challenges of divorce. Children who have a positive relationship with their non-custodial parent are more likely to have high self-esteem, fewer behavior problems, and better academic achievement than children who do not have such a relationship.In addition, the quality of the parent-child relationship with the custodial parent is also crucial for children's adjustment to divorce over time. Children who receive emotional warmth, affection, and guidance from their custodial parent are more likely to feel secure, valued, and loved, which in turn promotes their emotional, psychological, and social well-being. Moreover, children who have open and honest communication with their custodial parent about the divorce and its impact on the family are more likely to have a realistic and positive view of the situation and less likely to blame themselves or their parents for the divorce. Therefore, it is important for parents to prioritize their children's emotional needs and maintain supportive and healthy relationships with them before, during, and after divorce.

Answers

Rule of Inference used: Disjunctive syllogism.

The conclusion that follows is Tina is smart. Because we know that Tina is not lucky, which means she cannot get a scholarship because she has to be lucky to receive a scholarship. However, Tina is either smart or lucky, and since Tina is not lucky, it is valid to conclude that she is smart.b)Proof by contrapositive:If n and m are integers and n*m are odd, then n and m are odd. We can write this statement in the form of a conditional statement as P → Q where P = n*m are odd, Q = n and m are odd.

The contrapositive of P → Q is ¬Q → ¬P. We have to prove the contrapositive that if n and m are even, then n*m is even. If n and m are even, then we can write n = 2p and m = 2q, where p and q are integers. n*m = 2p * 2q = 4pqSince p and q are integers, the product pq is also an integer, and the product of two even numbers is always even.

suppose that orchid currently has 12 research scientists and does not anticipate being able to hire more in the near future. how should orchid prioritize these projects?

Answers

If Orchid currently has 12 research scientists and does not anticipate being able to hire more in the near future, then it should prioritize its projects based on the following criteria: Project timelines. Project importance. Scientists' qualifications.

Each project has a set timeline that determines its delivery date. The time required to complete a project and its expected delivery date should be considered. The importance of each project should be considered since some projects may be more important than others. The qualifications of the scientists working on each project should be taken into consideration. This is because a project that requires expertise in a specific field should be assigned to a scientist who has the necessary qualifications. The availability of resources such as funding and research tools should also be considered. Projects that have insufficient resources should be postponed or canceled to allow for the completion of more important projects with adequate resources.

the normative model of rational decision making is group of answer choices maximization of expected subjective utility loss aversion the availability heuristic satisficing

Answers

The normative model of rational decision making is a group of principles that guide individuals to make decisions that maximize their expected subjective utility. It includes various strategies such as loss aversion, the availability heuristic, and satisficing.

The primary focus of the normative model is to ensure that the decision made by an individual is optimal given the available information. In other words, it attempts to make the decision-making process as efficient as possible by reducing cognitive load, increasing information processing speed, and minimizing the amount of information required to make a decision. The normative model assumes that individuals are rational and capable of making decisions that are in their best interests. However, it is important to note that this model is not always followed by individuals in real-world situations, and there may be various factors that influence their decision-making process.

what would happen if activation energy barriers didn't exist?

Answers

If activation energy barriers didn't exist, chemical reactions would occur much more readily and rapidly. Activation energy refers to the minimum energy required for a chemical reaction to occur, which allows the reactant molecules to overcome energy barriers and reach a reactive state.

Here's what would happen if activation energy barriers were absent:

Increased Reaction Rates: Reactions would proceed at a significantly faster rate since molecules would have sufficient energy to react without the need for additional energy input. This means that even low-energy collisions between reactant molecules would result in successful reactions.

Increased Frequency of Reactions: Without activation energy barriers, a larger number of collisions between reactant molecules would lead to successful reactions. This would result in a higher frequency of reactions taking place, as a larger proportion of collisions would have sufficient energy to proceed.

Uncontrolled Reactions: Activation energy acts as a barrier that prevents certain reactions from occurring under normal conditions. Removing this barrier would allow reactions to occur spontaneously, including those that are typically undesirable or dangerous. This could lead to uncontrolled chemical reactions, potentially causing damage to the environment or posing risks to safety.

Loss of Selectivity: Activation energy also plays a role in determining the selectivity of reactions, allowing specific pathways to be favored over others. Without activation energy barriers, selectivity in reactions would be diminished, leading to a broader range of reaction products and reduced control over the desired outcome.

In summary, the presence of activation energy barriers is crucial for regulating the rate, selectivity, and control of chemical reactions. Removing these barriers would result in faster reaction rates, increased frequency of reactions, potential loss of selectivity, and the possibility of uncontrolled reactions.

when developing the object relational model in the file for a django project, data types for each attribute must be of answer choices

Answers

In Django, the ORM is responsible for generating SQL queries and making them work with the underlying database.

The model represents the database's structure, including data types. Models are defined in a Python file that is typically located in an application's models.py file. Attributes for an object are specified with variables in the model class.The choice of data type for each attribute will be determined by the requirements of the Django project and the database backend in use. Common data types include CharField, IntegerField, BooleanField, DateField, DateTimeField, and so on.Each attribute's data type should be chosen based on the data it will contain and the constraints it will impose on the database.

When defining a Django model, it's crucial to consider the database schema and ensure that the data types used for the attributes are compatible with the backend database. Usually, the model represents the database structure and the relationship between them. The developers of Django who came up with the framework call it "model/view/controller" as opposed to "model/view/template." The idea is that Django provides a rich layer of ORM, which stands for Object-Relational Mapping. ORM allows you to represent all the objects in your application using Python classes that reflect the object's data model.

the resource allocation method used for the online auctions on ebay is

Answers

The resource allocation method used for online auctions is a form of the ascending-bid auction, specifically known as the English auction.

In an English auction, the starting bid is set low, and participants incrementally increase their bids until no higher bids are offered. The highest bidder at the end of the auction wins the item.

The English auction format is commonly used, allowing sellers to list items with a starting price and a duration for bidding. Potential buyers then have the opportunity to place bids on the item, increasing the price with each bid. The auction continues until the specified duration ends or until a bidder places a bid higher than any other current bid.

At the end of the auction, the highest bidder wins the item and is obligated to complete the purchase by paying the final bid amount to the seller.
