Answer:
Curve of forgetting
Explanation:
Curve of forgetting or the forgetting curve was developed by a German psychologist named Hermann Ebbinghaus.
The forgetting curve demonstrates the declination of memory maintenance or retention in time. It states that there is a loss in memory or information over a period of time if memory rehearsal or retention is not being done.
The brain lacks the ability to a piece of memory over time if the memory is not being recalled or retained.
In the case of Lisa, in the given question loss of memory occurs because the memory has not been consciously reviewed again.
Other things held constant, if the expected inflation rate DECREASES, and investors also become MORE risk averse, the Security Market Line would shift in<u> have a steeper slope </u>manner.
<h3>What is the Security Market Line (SML)?</h3>
The security market line (SML) is the Capital Asset Pricing Model (CAPM). It gives the market’s expected return at different levels of systematic or market risk. It is also called the ‘characteristic line’ where the x-axis represents the asset’s beta or risk, and the y-axis represents the expected return.
<u>Security Market Line Equation</u>
The Equation is as follows:
SML: E(Ri) = Rf + βi [E(RM) – Rf]
In the above security market line formula:
- E(Ri) is the expected return on the security.
- Rf is the risk-free rate and represents the y-intercept of the SML.
- βi is a non-diversifiable or systematic risk. It is the most crucial factor in SML. We will discuss this in detail in this article.
- E(RM) is expected to return on market portfolio M.
- E(RM) – Rf is known as Market Risk Premium.
<u>Characteristics of the Security Market Line (SML) are as below:</u>
- SML is a good representation of investment opportunity cost, which combines the risk-free asset and the market portfolio.
- Zero-beta security or zero-beta portfolio has an expected return on the portfolio, which is equal to the risk-free rate.
- The slope of the Security Market Line is determined by the market risk premium, which is: (E(RM) – Rf). Higher the market risk premium steeper the slope and vice-versa
- All the assets which are correctly priced are represented on SML.
- The assets above the SML are undervalued as they give a higher expected return for a given amount of risk.
- The assets below the SML are overvalued as they have lower expected returns for the same amount of risk.
Therefore, we can conclude that the correct option is A.

Answer:
Covering approximately 800 miles, the Santa Fe Trail extends from Independence, Missouri to present day Santa Fe, New Mexico. The Trail originally began in Franklin, Missouri, but the trail head was moved to Fort Osage and, by 1827, to Independence. ... The Santa Fe Trail was first used in 1821 by William Becknell.
Explanation:
This question is missing the options. I've found the complete question online. It is a follows:
While watching television, Jason comes across an advertisement on a new soft drink brand. This advertisement reminds him that he is thirsty and wants to buy a beverage. In the context of reinforcement theory, the advertisement
serves as a(n) _____.
a. orienting reflex
b. stimulus
c. heuristic
d. cognitive map
Answer:
In the context of reinforcement theory, the advertisement serves as a(n) b. stimulus
.
Explanation:
In reinforcement theory, a stimulus is any external event that leads to a change in behavior, a response. Stimuli can actually be used to condition certain desired behaviors in animals and people by being paired up in ways that lead to specific responses. In the case described in the passage, Jason was led to feel the urge to buy a beverage because of the ad. Jason's behavior was a response to the ad, which means the ad itself is a stimulus.
