Answer:
1.03
Explanation:
Beta is used to measure systemic risk. The higher beta is, the higher the systemic risk and the higher the compensation demanded for by investors.
Systemic risk are risk that are inherent in the economy. They cannot be diversified away.
The portfolio's beta can be determined by adding together the weighted beta of each stock in the portfolio
weighed beta of a stock = percentage of the stock in the portfolio x beta of the stock
Stock Q = 0.35 x 1.34 = 0.469
Stock R = 0.25 X 0.88 = 0.22
Stock S = 0.15 x 0.57 = 0.0855
Stock T = 0.25 x 1.02 = 0.255
Portfolio beta = 0.469 + 0.22 + 0.0855 + 0.255 = 1.0295 = 1.03
Results Structural equation modeling indicated a) lower levels of available support for diabetes management, higher depression scores and older age predicted more peer contact and b) more contact predicted lower final HbA1c levels, as well as lower baseline BMI and diabetes anxiety and fewer years of life with diabetes
The model equations are the conservation of mass, energy and momentum in their basic form, i.e. the sum of inflows and outflows and also the transformation of one conserved quantity into another.
The mathematical model we just used was in the form of a formula or equation. Equations are the most common type of mathematical model. Here is another example of an equation as a mathematical model. Let's say a store is having a sale where everything in the store is 15% off.

Answer: 28.2%
Explanation:
Correlation Coefficient = Covariance / (Standard deviation of Security A * Standard deviation of Security B)
0.52 = 0.022 /( 15% * σ)
(15% * σ) * 0.52 = 0.022
15% * σ = 0.022 / 0.52
σ = 0.0423/15%
= 28.2%
In a free market economy, the market, not the government, determines prices. The interaction of producers and consumers determine the price in the market.
Answer:
Self-interest in a market system will automatically promote the public interest as well.
Explanation:
An economy is a function of how money, means of production and resources (raw materials) are carefully used to facilitate the demands and supply of goods and services to meet the unending needs or requirements of the consumers.
Hence, a region's or country's economy is largely dependent on how resources are being allocated and utilized, how many goods and services are to be produced, what should be produced, for whom they are to be produced for and how much money are to be spent by the consumers to acquire these goods and services.
A free-enterprise system also referred to as capitalism or free market can be defined as a type of economy in which prices, products and services are being determined by the market rather than the government. Thus, a free-enterprise system is devoid (free) of government regulations, interference or control because the market (enterprises) are the ones who are saddled with the responsibility of determining the market forces.
Simply stated, a free-enterprise system is a type of economy that is completely driven by demand and supply of goods and services.
The "invisible hand" concept asserts that the self-interest by producers and suppliers of resources in a market system will automatically promote the public interest as well.
This ultimately implies that, public and private interest will always coincide assuming there exist competition in a free market system.
In conclusion, the invincible hand concept is a metaphorical description of the unforeseen forces that typically moves a free market system or economy.
