Answer: C. The security risks associated with combining USB drives and cell phones on a network
D. The risks associated with the large capacity of USB drives and their concealable nature
Explanation:
Based on the scenario that has been discussed in the question, the security administrator will instructs the marketing staff not to supply the USB pens based on the security risks that are associated with combining USB drives and cell phones on a network.
Another reason is due to the risks that are associated with the large capacity of USB drives and their concealable nature.
Since the client has been victimized by social engineering attacks that led to a loss of sensitive data in the past, they'll be extra careful this time around.
Answer:
C. can cause hypothesis tests to be unreliable
Explanation:
Omitted variables are those variables that, when left out of a statistical model, for example linear regression, affects the outcome of the model. It either ignores the impact of the omitted variable to the results or it may assign the effect of the omitted variable incorrectly to the effect of the included variable on the statisical model. This of courses results in the model depicting an upward bias or a downward bias. This is referred to as the Omitted Variable Bias (OVB).
Lets take an example. If you were to run multiple regressions to figure out the factors that affect the prices of houses in an area, you would include multiple variables that you deem significant. The variables you would include in the regression model would include the age of the house, the size of the house, the number of rooms and so on and so forth. However, lets assume that some of the houses are located near an industrial waste plant which negatively impact the price of the house. You forget to include thos proximity variable in your model which would likely make your model biased since the proximity to a waste plant would drastically impact the price of a house that is similar in all aspects with a house that is located further away.
Furthermore, the aren't any statistical models that would located omitted variables therefore, in the context of the question, omitted variables can cause hypothesis tests to be unreliable
Answer:
$250 is the answer
Explanation:
As we want to calculate here the net income which could be found from the following formula:
Net Income or Profit = Sales - Expenses
In this case the sales figure is $750 and the expenses are $500.
By putting the values we have
Net Income = $750 - $500 = $250
Investment B is an ordinary annuity with an annual contribution of $1,100.
Option C
Explanation:
An annuity is an equivalent payment show made over a fixed period at the end of consecutive periods.
While regular annuity payments are made as frequently as every week, usually monthly, quarterly, semi-annually and annually. In practice, payments are made. The reverse of an ordinary rental is an annuity to be paid at the start of each period.
Consistent quarterly investment earnings are an example of ordinary rents; monthly rents are a case in point of the due rents.
