Issac is seeking challenge response token type of solution.
Explanation:
Difficulty-response encryption is in computer security a group of protocols where one party raises a request ("Challenge") and then another group must send a valid answer ("Response"). User verification, the most basic example of a request-response protocol, is the task for the right user.
Authentication of the Challenge response requires a cryptographic protocol to indicate that the recipient does not know the password by themselves. The result is then computed with the use of a cryptographic hash function in conjunction with the password of the recipient.
Answer:
d. changes in the prices of stocks are not predictable. Evidence shows that indexed funds typically do better than managed funds.
Explanation:
"The efficient market hypothesis was developed from a Ph.D. dissertation by economist Eugene Fama in the 1960s, and essentially says that at any given time, stock prices reflect all available information and trade at exactly their fair value at all times. Therefore, it is impossible to consistently choose stocks that will beat the returns of the overall stock market. Basically, the hypothesis implies that the pursuit of market-beating performance is more about chance than it is about researching and selecting the right stocks."
Evidence about indexed funds vs. managed funds:
While actively managed funds may perform well in the short-term, index funds have higher returns over longer periods of time. This is because the index fund, a type of mutual fund or exchange-traded fund (ETF), is designed to follow predetermined guidelines in order to track a specific underlying set of investments, and is therefore passively managed."

11.2%
Explanation:
We need to calculate the weighted return of the portfolio. You have to multiply each stock's weight by the expected return.
- Stock X = 0.30 x 9% (expected return) = 2.7%
- Stock Y = 0.20 x 15% (expected return) = 3%
- Stock Z = 0.50 x 11% (expected return) = 5.5%
- weighted return of the portfolio = 2.7% + 3% + 5.5% = 11.2%
