Answer:
Option b. A and B are conditionally independent given C2.
Explanation:
The conditional probability of an event is the probability that a given event will occur given that another event, say A has already occurred.
In a case where events A and B are independent (in this case, where the probability of A has no effect on the probability of B occurring), the conditional probability of an event B given that A has taken place is simply the probability of the event A.
If the two events are not independent, then the probability of an event occurs as an intersection of set A and B.
Question 2 options are;
- government
- market
- firm
- business sector
Answer:
1. microeconomics concentrates on the behavior of individual consumers and firms, while macroeconomics focusses on the performance of the entire economy.
2. government.
Explanation:
1. Indeed, the government in a command economy (like China) makes most economic decisions itself or at least strongly influences how the decisions are made.
2. We note that the word 'macro' indicates large scope, while 'micro' indicates a smaller scope. And so, the difference is that microeconomics concentrates on the behavior of individual consumers and firms, while macroeconomics focusses on the performance of the entire economy.
Answer:
PV = $78.46153 rounded off to $78.46
Explanation:
A perpetuity is an unlimited series of cash flows that are of constant amount and occur after equal intervals of time. As they are unlimited in number, we say that they are perpetual. A perpetual preferred stock can also be said to be in form of a perpetuity as it pays a constant dividend after equal intervals of time. To calculate the price of the preferred stock, we use the present value of perpetuity formula which is,
PV = Cash flow / r
Where,
- r is the required rate of return
PV = 5.1 / 0.065
PV = $78.46153 rounded off to $78.46
Answer:
fixed income
Explanation:
During the expansion business cycle, economic activities are on the increase. Key economic indicators such as employment, incomes, business earnings, demand, and supply of goods and services show positive and progressive numbers. During expansion, the GDP growth rate is healthy, and the level of investment is high.
The expansion phase brings along inflationary pressure. At the peak or near the end of the expansion cycle, the inflation rate is always above the optimal level and sometimes in double digits. A high rate of inflation weakens the purchases power of the local currency. Employees on a fixed income will be disadvantaged. Their income will afford them fewer goods and services compared to the period before expansion.
Answer:
$26,000
Explanation:
Revenue for Charlie's chocolate is $97,000
Expenses is $71,000
Therefore the net income can be calculated as follows
= revenue - expenses
= $97,000-$71,000
= $26,000
Hence the net income is $26,000
