Answer:
E) Oil imports declined as countries exporting oil reduced supply.
Explanation:
Oil is extremely important for industrialized nations and since Euphrasia is a mixed open economy, we can assume that it is an industrialized nation. Oil has become the most important energy source for more than 60 years and is the raw material for manufacturing plastic.
During the 1970s and early 1980s the American economy was shattered by an increase in the price of foreign oil and a decrease in its domestic production levels. The importance of oil is also why so many modern wars have been fought over oil production and reserves.
Answer:
<u></u>
- <u>1. The slope is negative</u>
- <u>2. The demand decreases when the prices increase.</u>
Explanation:
<em>Describe the slope of the demand curve?</em>
<em>The slope of the demand curve</em> is negative.
The demand curve is graphed on a coordinate plane with the price in the horizontal axis (typically the x-axis) and the demand on the vertical axis (y-axis).
Thus, the slope will be the rate of change of the demand over the change on the price.
Mathematically:

Since, as you move from left to right, on the x-axis, the prices increase, and the demand (on the y-axis) lowers, the change in demand is negative and the change in the prices is positive, resulting in a negative slope.
This is seen graphycally because the demand curve is decreasing (downward-sloping).
<em>How does the slope reflect the law of demand?</em>
The slope reflects perfectly <em>the law of demand</em> because the law of demand states that, since the resources are scarce, when the prices incrases the quantities demanded decrease.
Answer:
Dividend yield for W = 5%
Dividend yield for X = 15%
Dividend yield for Y = 20%
Dividend yield for Z = 4.6%
Explanation:
For a constant growth stock 
If r is made subject of formula; r=
= div yield + growth rate
For Stock W, given r = 15% and g= 10%; dividend yield = 15%-10%=5%
For Stock X, given r = 15% and g= 0%; dividend yield = 15%-0%=15%
For Stock Y, given r = 15% and g= -5%; dividend yield = 15%-(-5)%=20%
For Stock Z, the price of the stock today is calculated as follows:
Price of the stock today =
.
where P2= 
Price of the stock today =
=109.57
Therefore dividend yield =
=
4.6%
