Answer:
Therefore, Olivia should buy 10 apples and 8 bananas to maximize her utility.
Explanation:
Let A represent the number of apples bought and B represent the number of bananas bought. Therefore since Olivia has $4 to spend:
0.2A + 0.25B = 4 (1)
Also, the tangency condition can be used to find the optimal amount of A to relative to B. It is give as:

Put B = 0.8A in equation 1:
0.2A + 0.25(0.8A) = 4
0.2A + 0.2A = 4
0.4A = 4
A = 10
B = 0.8(A) = 0.8(10) = 8
Therefore, Olivia should buy 10 apples and 8 bananas to maximize her utility.
The answer to this question is: Quality
The limits of the terms of trade are determined by the comparative cost conditions in each country before trade:
Less commerce occurs as a result of partial specialization and rising costs than when costs are constant. The cost advantage one country has over another serves as the foundation for commerce. This explains why some countries make things that they also import since they are able to do so for less money than their trading partners.

Answer:
The bond has a 2 percent coupon and a face value at issuance of $1000 which is the same with the Treasury inflation-protected bond. However, the reference Consumer Price Index (CPI) which is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services has increased from 202.34 to 203.18. From this deduction, what I know for certain about this bond is that the interest payment have increased and the coupon rate is still 2 percent.
Answer: D. A confidence interval is used to test a claim about two population proportions.
Explanation: Confident interval estimate is a type of estimate computed from statistics of observed data.
The confident interval estimate of the difference between two population proportions will use a standard deviation based on estimated values of the population proportion. The confident interval will be used to estimate the difference in the two population proportions, but it will not be used to test claim about two population proportions because it can not.
