Answer: The standard deviation of the stock is 3.23 percentage
Explanation:
First we shall calculate the epected weighted average return of the stock.
We shall multiply the probability of the scenario with its expected return and then take the sum of the expected returns of different scenarios,
E(x) = (0.2 x 14%) + (0.7 x 8%) + (0.1 x 2%)
E(x) = 8.6%
We shall use the follwing formula to calculate the Variance of the stock,
σ²(x) = ∑ P(
) × [ - E(r)]²
σ²(x) = (0.2) (0.14 - 0.086)² + (0.7) (0.08 - 0.086)² + (0.1) (0.02 - 0.086)²
σ²(x) = 0.001044
To find the standar deviation,
σ(x) = 
σ(x) = 0.0323109
in percentage it would be 3.23%
The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
Answer:
The need for organisations (which may be governmental or non-governmental) to improve the condition of living of people and protect their environment whilst they pursue increased profitability has been termed
The Triple Bottomline.
It is also referred to by economists as the 3P - People, Planet and Profit.
It speaks to the fact that other than the usual making financial success the sole metric of measurement by which organisations are evaluated, their impact on people and the environment should be considered as well.
In simple terms, a firm should be termed more successful than others if it's activities besides being profitable also impacts positively on people and protects if not improves the environment.
Cheers!
self-organization versus hierarchical organization — a mathematical investigation of the anarchist philosophy of social organization
In combining anarchist theory with mathematics, this thesis wishes to better understand what power and hierarchy are in order to explore how we can live without coercion.
The process by which individuals organise their social relationships to bring about global order through their interactions with one another rather than through external intervention or teaching is referred to as self-organization. The nervous system exhibits many self-organizational characteristics since it is a very complex and dynamic system with several pieces interacting with one another. In this chapter, we will talk about three different types of brain self-organization: self-organization during development, self-organization as a result of experience, and self-organization as a result of damage. The development of the nervous system is affected by self-organization. Since it is difficult to explain how the nervous system, which is highly structured and complicated, can develop from a single fertilised egg, this is a crucial issue in our knowledge of the neurological system.
