Suppose the beta of Microsoft is 1.13, the risk-free rate is 3 percent, and the market risk premium is 8 percent. Calculate the expected return for Microsoft.
Answer:
8.65%
Explanation:
Rj = Rf + risk premium.
Rj = Rf + β[E(RM − Rf)].
= 3 + 1.13 (8 - 3)
= 3 + 1.13 x 5
= 3 + 5.65
= 8.65 percent
This relationship between risk and expected return is called the security market line.
The expected return for Microsoft, using CAPM and the given risk-free rate, beta, and market risk premium, is 12.04 percent.
To calculate the expected return for Microsoft, given that the beta of Microsoft is 1.13, the risk-free rate is 3 percent, and the market risk premium is 8 percent, we can use the Capital Asset Pricing Model (CAPM). The CAPM formula is:
Expected Return = Risk-Free Rate + (Beta Times Market Risk Premium)
Plugging in the given values:
Expected Return = 3% + (1.13 Times 8%)
Expected Return = 3% + 9.04%
Expected Return = 12.04%%
Therefore, the expected return for Microsoft is 12.04% percent.

Answer:
Option B; 30 SECONDS OR LESS.
Explanation:
Short-term memory, also known as primary or active memory, is the information we are currently aware of or thinking about.
When short-term memories are not rehearsed or actively maintained, they last mere seconds.
Most of the information kept in short-term memory will be stored for less than 30 seconds (approximately 20 to 30 seconds), but it can be just seconds if rehearsal or active maintenance of the information is not done.
Therefore, Anita likely will be able to retain the information in short-term memory, without additional processing, for 30 SECONDS OR LESS.

Answer:
Option B is correct.
Explanation:
Within Techno Info Systems the user has been analyst contemplating that four-model concept towards computer development for such its new customer. When they adopt that four-model method, thus the result seems to be the time taken to implement the rises in the method.
So, therefore the other options are incorrect according to the following scenario.
Final answer:
Using the four-model approach to system design likely leads to an increase in the time taken to develop the model, as it entails creating complex and detailed models to replace the real system for analysis.
Explanation:
If the analysts at Techno Info Systems employ the four-model approach to system development for a new client, a likely outcome is that time taken to develop the model increases. This approach involves creating different models, each with its purpose and complexity. For instance, understanding ecosystem dynamics necessitates analytical and simulation models that can predict the consequences of changes within an ecosystem. Similarly, a four-model approach in system development requires meticulous detail, and this extensive modeling aims to replace the real system with an easier-to-examine version, ultimately providing more reliable predictions and a detailed design.
However, as the complexity of models increases with the aim of better accuracy and understanding, it also often leads to longer development times. While the models serve to understand the system before making modifications, a more detailed four-model approach means investing more time to build and analyze each model. One must balance the drive for comprehensive understanding against the requirement to deliver results in a timely manner.
