Which of the following methodologies might be most appropriate if you have a system project with:unclear user requirements; unfamiliar technologies; somewhat complex; needs to be reliable; time isnot an issue and the schedule visibility is somewhat important?
a) Waterfall
b) Parallel
c) Iterative
d) System prototyping
e) Throwaway prototyping
Answer: Throwaway prototyping
Explanation:
Waterfall is used when the system has clear requirements, reasonably reliable, very familiar technologies, isn't too complex. It's also used when there's a very long time schedule and in a scenario whereby the schedule visibility isn't important.
Parallel is used when the system project has clear requirements, shirt time schedule, technologies that are very familiar, not all that complex; reasonably reliable, and the schedule visibility is not important.
With regards to the question, the description given fits a throwaway prototyping. Therefore, the correct option is E.

process?
A chlorobromide
B. bromide
C. chloride
D platinum
Answer:
A. Chlorobromide
Explanation:
I took the test and got it right. (Plato)
The type of black-and-white paper emulsion should be used by Jim is chlorobromide. Thus, option (A) is correct.
What is emulsion?A sort of colloid called an emulsion is created by mixing two liquids that wouldn't typically mix. A dispersion of the other liquid is present in one liquid in an emulsion.
Emulsions frequently occur in foods like egg yolk, butter, and mayonnaise. Emulsification is the process of combining liquids to create an emulsion.
According to the above scenario, Jim wishes to expand a warm-toned black-and-white photograph. For this purpose, he should use chlorobromide for black-and-white paper emulsion.
Paper covered with a chemical compound that is light-sensitive, which is inferred as photographic paper. When exposed to light, it captures the latent image.
Therefore, it can be concluded that option (A) is correct.

Compare the delay in sending an x-bit message over a k-hop path in a circuit-switched network and in a (lightly loaded) packet-switched network. The circuit setup time is s sec, the propagation delay is d sec per hop, the packet size is p bits, and the data rate is b bps. Under what conditions does the packet network have a lower delay? Also, explain the conditions under which a packet-switched network is preferable to a circuit-switched network.
A physical link must be established between two nodes in a circuit-switched network before the nodes can communicate with one another.
An advance over earlier network types, a packet-switched network is a digital network that controls data transport in the form of compact, efficient packets. The application would perform best over a circuit-switched network since it requires lengthy sessions with steady, predictable bandwidth needs. Because the transmission rate is steady and known, it is possible to reserve bandwidth for each application session without wasting much of it. Circuit switching is connection-oriented, whereas packet switching is connectionless, and this is the main distinction between the two. The two most popular switching techniques are these two.

How does this work ?In this macro, we declare three integer variables: A, B, and C. We set the initial value of C to 0 and A to 0.Then, we check if B is different from C using the <> operator.
If B is indeed different from C, we assign the value of B to A. Finally, the values of A and C are displayed in the immediate window using the Debug.Print statements.

For which task is the goal seeker feature most helpful?
The goal seeker feature is most helpful for finding the input value needed to achieve a specific desired output in a mathematical model or spreadsheet.
The goal seeker feature is a valuable tool in applications like spreadsheets or mathematical modeling software. It assists in finding the input value required to achieve a specific desired output or goal. This feature is particularly useful when you have a target value in mind and need to determine the corresponding input value that will result in that desired outcome.
For example, in a financial spreadsheet, you might want to determine the interest rate needed to achieve a certain future value for an investment. By utilizing the goal seeker feature, you can specify the desired future value and instruct the software to find the interest rate that would produce that outcome.
The goal seeker will then iteratively adjust the input value (interest rate) until it reaches the desired output (future value).
In mathematical modeling, the goal seeker can be used to solve equations where one variable depends on others. If you have an equation with multiple variables and want to find the specific value of one variable that satisfies a particular condition or equation, the goal seeker can automatically determine the input value that achieves the desired outcome.
Overall, the goal seeker feature is particularly helpful when you have a specific target or goal in mind and need to determine the input value necessary to achieve that desired output in mathematical models, spreadsheets, or other similar applications.

A Web server has five major components that must all function in order for it to operate as intended. Assuming that each component of the system has the same reliability and one of the components will have a backup with a reliability equal to that of any one of the other components, what is the minimum reliability each one must have in order for the overall system to have a reliability of 0.696
Answer:
The answer is below
Explanation:
Let x represent the reliability of each of the five major components. Since all the components must function before the system operates, hence they are in series with each other.
One component has a backup of the same reliability, the reliability of the back up system = 1 - (1 - x)² = 2x - x²
Therefore the reliability of the system is:
x * x * x * x * (2x - x²) = 0.696
2x⁵ - x⁶ = 0.696
x⁶ - 2x⁵ + 0.696 = 0
Solving the polynomial equation online using byjus.com gives:
x = 0.915038
x = 1.97695
x = -0.632585 - 0.429075 i
x = -0.632585 + 0.429075 i
x = 0.186590 - 0.789741 i
x = 0.186590 + 0.789741 i
Since the reliability is not a complex number and it is less than or equal to 1, hence:
x = 0.915038, x ≅ 0.915

So, there are letters and digits that will be used. Assume that the letters can be repeated. How many employee ID codes can be generated
Answer:
82,944 = total possible ID's
Explanation:
In order to find the total number of combinations possible we need to multiply the possible choices of each value in the ID with the possible choices of the other values. Since the ID has 3 letters and 1 digit, and each letter has 24 possible choices while the digit has 6 possible values then we would need to make the following calculation...
24 * 24 * 24 * 6 = total possible ID's
