Answer:
Calcium carbonate reacts w/stomach acid according to the following chemical equation.
CaCO3+2HCl(aq)-> CaCl2(aq)+H2O(l)+CO2(g)
Answer: The same amount of dollars
When it comes to the financial level, a replicating portfolio as the name implies, is a repetition of specific flows of a given asset, so it must be constituted with the same resources. In this case, the same amount of cash would be needed to create the replica.
The portfolio beta would simply be the summation of the
weighted average of each beta.
Where weighted average of each beta is calculated as:
Stock weighted average = Stock proportion * Individual
beta
Therefore,
Stock A beta weighted average = 0.2 * 0.4 = 0.08
Stock B beta weighted average = 0.3 * 1.2 = 0.36
Stock C beta weighted average = 0.25 * 2.5 = 0.625
Stock D beta weighted average = 0.25 * 1.75 = 0.4375
The summation of all betas yield the overall portfolio
beta:
Portfolio beta = 0.08 + 0.36 + 0.625 + 0.4375
<span>Portfolio beta = 1.5025 ~ 1.5</span>
Answer:
The correct answer is option d.
Explanation:
The most effective model to understand the effect of change of a variable on other variable is by assuming other factors to be constant. This simplifies the model and helps in easily understanding the relationship between the two variables.
Though the assumption of other things being constant does not apply in the real world, it is still used as otherwise change in other factors would complicate the model. If several factors change it would be difficult to understand the relationship between variables.
Here, to study the effect of change in the price of grapes on the market for wine, it is necessary to assume other factors such as income, consumer preferences, etc to be constant.
