Answer:
Ans. The average annual rate of return over the four years is 2.792%
Explanation:
Hi, first let´s introduce the formula to use
![r(Average)=\sqrt[n]{(1+r(1))*(1+r(2))*(1+r(3))+...(1+r(n))}-1](https://tex.z-dn.net/?f=r%28Average%29%3D%5Csqrt%5Bn%5D%7B%281%2Br%281%29%29%2A%281%2Br%282%29%29%2A%281%2Br%283%29%29%2B...%281%2Br%28n%29%29%7D-1)
Where:
r(1),(2),(3)...n are the returns in each period of time
n =number of returns to average (in our case, n=4).
With that in mind, let´s find the average annual return over this four years.
![r(Average)=\sqrt[4]{(1+0.025)*(1+0.025)*(1+0.12)+(1-0.07))} -1=0.022792](https://tex.z-dn.net/?f=r%28Average%29%3D%5Csqrt%5B4%5D%7B%281%2B0.025%29%2A%281%2B0.025%29%2A%281%2B0.12%29%2B%281-0.07%29%29%7D%20-1%3D0.022792)
Therefore, the average annual return of this invesment in 4 years is 2.2792%
Best of luck.
Answer:
Answer is option a, i.e. trade-offs and connections may differ in short run and the long run.
Explanation:
Keynes' law in economics and Say's law in economics are contradictory in their perspective. Where Keynes' law says that it is the demand that creates the supply, on the other hand, Say's law states that its the supply that tends to create the demand. But, we cannot neglect any of the above facts as demand and supply cant operate independently. So, on combining the two laws, we happen to take both the given laws into account. Also, it is found that Keynes' law is more appropriate and accurate for the short-run whereas, Say's law is for the long run. This thus creates trade-offs and connections that differ in the short-run and long-run by affecting the three important goals of macroeconomics, i.e. higher standard of living, low inflation, and low unemployment.
Answer:
b. are usually composed of diagrams and equations.
Explanation:
Economic models involve huge number of factors for their study and analysis.
It encompasses the analysis of various situations in an economy. It amounts for significant influence on the changes in market and environment, in which an economy runs.
Since it is complex in nature it involves huge diagrams, metrics, equations.
As with just theory it is not easy to form the understanding of economics. Thus, it involves many pictorial representations in the form of diagrams, graphs, etc:
Therefore, correct statement is
Statement b
