Answer:
a. Numbers
Explanation:
The values in a chart represent data. Anyone reading a chart should be able to interpret the information presented with relative ease. Due to the space factors, the values of a chart are always in numbers. Values in number form take little space compared to words.
Numbers are clear and easy to understand for everyone. When a value is very big, writing it in words may pose a challenge for some people to understand.
Economic Activities are the actions related to the production, distribution, and exchange of goods and services. So for an evening news bulletin on TV or radio, some examples are:
- The service of the reporters who research a story and check facts
- The cost of paper and materials used in the newsroom
- The equipment that establishes a TV or radio signal and broadcasts it out to people
- Cable service or radios that are purchased in order to hear/see the news
Answer: GHI Bonds
Explanation:
All the bonds are of equal maturity so the only relevant variable is the bond yield.
Bond prices are inversely related to the market interest rate for the simple reason that bond yield is fixed. As a result when interest rates go up, they will become less attractive because they will be paying older and lower rates than the newer rates.
This is especially true for bonds with lower yields which is why GHI Bonds will show the greatest change in price.
For instance, suppose interest rates in the economy were 6% and increased to 8%, the attractiveness of the 5% bond would decrease the most because there is a chance to earn 3% more in the market than from that bond.
Answer: Yellow dominates portfolios Blue and Purple.
Explanation:
Portfolio Yellow has a higher expected return than either portfolio Blue or Portfolio Purple which means that if we were evaluating the portfolios on return alone, Portfolio Yellow would dominate the other two.
However, we need to adjust for risk. The portfolio with the lowest standard deviation is the less riskier one of the three. That portfolio is Yellow which means that Yellow has both a higher expected return and a lower risk. It would therefore dominate the rest.
Option A and D contains same answer. Both options are incorrect
Operating systems provide both command line as well as graphical user interfaces
Explanation:
An immersive graphical component system for computer software is a graphical user GUI. A GUI is seen as more simple than a graphical unit-line interface, like MS-DOS or a Unix-like operating system shell.
In a GUI, commands like opening, deletion and moving files are executed using a window, an icon and menu. While a mainly mouse-based GuI operating system is used, a keyboard can also be used through keyboard shortcuts or arrow keys.
For example, you would move the mouse cursor to the icon of the program and double click on it to open a program on a GUI system.
