Answer:
Representative democracy.
Explanation:
Representative democracy refers to a system where the people govern through the election of parties or representatives with decision-making rights. Representative democracy can also be seen as a collective term for a number of democratic models. Common to these, however, is that the core consists of regularly recurring elections between competing representatives. People's sovereignty is achieved by the citizens influencing the government by voting in these elections. It is by far the most widespread method of exercising authoritative and legitimate control, demanding responsibility and developing debate in modern democracies.
Answer:
B. The portfolio expected rate of return must be the same for each economic state.
Explanation:
Variance formula = sum of (probability x (r - mean)^2)
r= expected return
if the expected return would be same for each economic state then the mean would equal to expected return which ultimately will give variance zero ( as r-mean would be 0).
Hence the correct option is B. The portfolio expected rate of return must be the same for each economic state.
Answer:
About the Lagrangian method,
We can use it to solve both consumer's utility maximization and firm's cost minimization problems.
Explanation:
Lagrangian method is a mathematical strategy for finding the maxima and the minima of a function subject to equality constraints. Equality constraints mean that one or more equations have to be satisfied exactly by the chosen values of the variables. Named after the mathematician, Joseph-Louis Lagrange, the basic idea behind the Lagrangian method is to convert a constrained problem into a Lagrangian function.
Answer:
The value of a firm's final product is the selling price whereas value added refers to the addition of value to the raw material (intermediate products).
Explanation:
The term "value added" describes the enhancement a company gives to its product before offering it to the customer. It can be considered as an extra special feature added by a company to increase the value of a final product.
