Answer:
B. narrow, have been unemployed for 15 weeks or more weeks.
Explanation:
Unemployment rate refers to the percentage of the total labor force in an economy, who are unemployed but seeking to be gainfully employed. The unemployment rate is divided into various types, these include;
I. Natural Rate of Unemployment (NU).
II. Frictional unemployment rate (FU).
III. Structural unemployment rate (SU).
IV. Actual unemployment rate (AU).
V. Cyclical unemployment rate (CU).
There are different measures used in the measurement of the unemployment rate in a country's economy and these includes;
I. U-1: this is the percentage of people that are unemployed for at least 15 weeks or more.
II. U-2: this is the percentage of the people who have lost their job or the people that finished a temporary job.
U-1 is a more narrow measure of unemployment rate than the conventional U-3 measure and U-1 counts as unemployed workers who have been unemployed for 15 weeks or more weeks.
Answer: B. Corporate Bonds and T-Bills
Explanation:
As you want to be 95% certain, this would require a 95% confidence interval.
With the given returns and standard deviations, the range of returns expected will be computed by;
Upper limit = Return + 2*SD
Lower limit Return - 2*SD
Stocks
Upper Limit = 18.37% + 2 (38.79%)
= 96.0%
Lower Limit = 18.37% - 2 (38.79%)
= -59.2%
S&P 500
Upper Limit = 11.84% + 2(20.01%)
= 51.9%
Lower Limit = 11.84% - 2(20.01%)
= -28.2%
Corporate Bonds
Upper Limit = 6.47% + 2(6.98%)
= 20.4%
Lower Limit = 6.47% - 2(6.98%)
= -7.5%
T-Bills
Upper Limit = 3.46% + 2(3.14%)
= 9.7%
Lower Limit = 3.46% - 2(3.14%)
= -2.8%
The lower limit show the lowest return achievable given a 95% confidence level.
<em>Only </em><em>Corporate Bonds</em><em> and </em><em>T-Bills</em><em> will give a minimum that is above 8% so they should be chosen. </em>
Answer:
C. Listeria monocytogenes
Explanation:
Meningitis is an infectious disease caused by the infection of meninges by virus or bacterial. This can lead to confusion, vomiting, depression etc.
When food that has been contaminated by a pathogen called listeria monocytogenes is consumed, it can develop into meningitis. Meningitis can be treated and controlled by the use of antibiotics, and in some cases the combination of two or more types may be required depending on the nature of infection.
The surplus to be determined in this problem is equal to the difference between the money willing to be paid and the value of the purchase. hence for Bob, surplus value is equal to 65- 45 or $20 while that of Bill is equal to 50-45 or $5. The total surplus for both boys is equal to $20 + $5 or $25.
