Answer:
The conclusion is incorrect; using the test case [0, 1, 4, 5] is not sufficient to conclude the program is correct.
Explanation:
From the code snippet given, we cannot conclude that the test case is sufficient.
One of the reasons is because the test case contains only integer variables.
Tests need to be carried out for other large and floating points numerical data types such as decimal, double, float, etc. except that when it's known that the inputs will be of type integer only else, we can't rush into any conclusion about the code snippet
Another reason is that input are not gotten at runtime. Input gotten from runtime environment makes the program flexible enough.
Lastly, the array length of the array in the code segment is limited to 4. Flexible length needs to be tested before we can arrive at a reasonable conclusion.
Answer:
Creating objects which people are going to interact with, designers have to be aware of those traits and take them into account in the process. ... Continuing the theme, user-centered design is more focused and concise version of human-centered design with deeper analysis of target audience.The user interacts directly with hardware for the human input and output such as displays, e.g. through a graphical user interface. The user interacts with the computer over this software interface using the given input and output (I/O) hardware.Human-centered design is a creative approach to problem solving and the backbone of our work at IDEO.org. It's a process that starts with the people you're designing for and ends with new solutions that are tailor made to suit their needs. ... Human-centered design consists of three phases.

Answer: 1.5 : 1
Explanation:
The average of 92 marks for the test is a weighted average of the proportion of students in the class.
Assume boys are in the proportion, x.
(90 * x) + (95 * (1 - x)) = 92
90x + 95 - 95x = 92
-5x = 92 - 95
-5x = -3
x = -3/-5
x = 0.6
Boys are 0.6 of the class
Girls are:
= 1 - 0.6
= 0.4
0.6 : 0.4
1.5 : 1
Options: True or false
Answer: True
Explanation:TCP(TRANSMISSION CONTROL PROTOCOL) is is an internet control protocol that allows Communication between internet users or computers by collecting and compiling packets of data and then sending such collected packets of data to the desired user.
Before using a TCP one must first create a connection which will enable it to effectively communicate with the other user.
TCP are established using sequence numbers which can be predicted by another party for their own personal gain.
