Answer:
The correct answer is Adaptive differential pulse code modulation
Explanation:
Adaptive differential pulse code modulation (ADPCM) is a variant of differential pulse-code modulation (DPCM) that varies the size of the quantization step, to allow further reduction of the required data bandwidth for a given signal-to-noise ratio. The output data rate can be dynamically adjusted between 16 kbit/s and 64 kbit/s in these applications.
A researcher administers a standardized test to the students in a school testing a new program as well as to students in a similar school as a control group. To what extent is comparison of the average scores for the two groups of students useful for determining the effects of the program?
Of limited usefulness as a pilot study but has many threats to validity T/F
Answer:
True.
Explanation:
An investigator administers a practice test as the intervention group for all the participants in a school testing out a new curriculum as well as for the participants in the individual school. The analysis of just the scores for the two groups of students is thus of limited usefulness as a pilot study but has many challenges to the point that it is useful to assess the results of the program.

What technique allows a programmer to change the way in which a method works internally without affecting programs that utilize the method?
Answer:
implementation hiding allows the programmer to change the way in which a method works internally without affecting the programs that utilize the method.
Explanation:
Implementation hiding is an example of encapsulation in OOP which enables a programmer or coder to hide method implementation from outside world and in this technique the program is also not affected by the method that it is using
Answer:
Implementation hiding.
Explanation:
A method is a group of one or more statements, defined in a class. The class holds the attributes and behaviours of objects in its class and implements the defined method from an interface.
To avoid the method statements from been seen, it is encapsulated, hidden internally but functional when called upon. This encapsulation process is called implementation hiding.

If you wanted to compute the correlation between one nominal level variable and one interval level variable, which type of correlation should you use?
Answer:
Phi .
Explanation:
If user needed to calculate the connection between one variable of minimal level and other variable of interval level. So, this is Phi correlation because the coefficient of phi is the function of the connection between material and event, where both variables are recorded (0, 1). That's why the following answer is correct.
Final answer:
To compute the correlation between one nominal level variable and one interval level variable, point-biserial correlation should be used as it measures the relationship between a dichotomous nominal variable and a continuous interval variable.
Explanation:
When looking to compute the correlation between one nominal level variable and one interval level variable, the appropriate statistical technique to use is a point-biserial correlation. This type of correlation is designed specifically to measure the relationship between a dichotomous nominal variable and a continuous interval variable. Since interval level data is quantitative and differences between data points are known and equal, while nominal level data represents discrete categories, point-biserial correlation can provide insights into the strength and direction of the association between these two distinct types of data.

If Tracy starts on the left edge of the canvas and moves forward 50 pixels, how many times will this code need to be repeated to have Tracy reach the right edge of the canvas?
answer choices
4 times
8 times
10 times
50 times
Final answer:
The number of times the code must be repeated depends on the width of the canvas, which is not provided. If hypothetically assuming a canvas width of 400 pixels, Tracy would need to move 8 times to reach the right edge.
Explanation:
The question 'If Tracy starts on the left edge of the canvas and moves forward 50 pixels, how many times will this code need to be repeated to have Tracy reach the right edge of the canvas?' is asking us to determine the number of iterations required for a movement command in a programming context to cross a given distance. To answer this, we need the width of the canvas in pixels. Once the width is known, we would divide it by the movement distance (50 pixels) to find out how many 50-pixel movements are needed to reach the right edge. Since the width of the canvas is not provided, we are unable to give a specific answer. However, if we assume the canvas is 400 pixels wide (as an example), then Tracy would need to move 400/50 = 8 times to reach the right edge.
Final answer:
To reach the right edge of the canvas, Tracy needs to repeat the code 10 times.
Explanation:
To reach the right edge of the canvas, Tracy needs to repeat the code multiple times. Let's assume that the canvas is 500 pixels wide. If Tracy moves forward 50 pixels each time, she will need to repeat the code 10 times (500/50 = 10) to reach the right edge of the canvas.

In this exercise, use the following variables : i,lo, hi, and result. Assume that lo and hi each are associated with an int and that result refers to 0.
Write a while loop that adds the integers from lo up through hi (inclusive), and associates the sum with result.
Your code should not change the values associated with lo and hi. Also, just use these variables : i,lo, hi, and result.
Answer:
result = 0
i = lo
while i <= hi:
result = result + i
i += 1
Explanation:
Initialize the result as 0 to hold the summation value.
Since we are asked not to change the value of lo and hi, our loop control variable is i and initially it starts from lo.
Since we are asked to add the number from lo to hi, while loop condition checks it.
While the condition satisfies (during each iteration), the value of i is added to the result and the value of i is incremented by one.
Final answer:
To add integers from lo through hi inclusively without changing their values, initialize i to lo, use a while loop to increment and add i to result until i exceeds hi.
Explanation:
To solve this exercise and add the integers from lo up through hi (inclusive), without changing the values associated with lo and hi, you can use a while loop in programming. To do this correctly, we will initialize a temporary variable i to the value of lo at the start and use it to iterate until it exceeds hi. The result variable will accumulate the sum of these integers. Here is how the code could look:
i = lo
result = 0
while i <= hi:
result += i
i += 1
This loop starts at lo, and for each iteration, it adds the value of i to result, then increments i by 1 until i is greater than hi. The key here is not altering the original values of lo and hi, fulfilling the problem requirement.

Your network is divided into two segments. As the signal travels down the first segment, it becomes weak. To amplify the signals passing to the second segment, the network engineer installed a networking device. Which networking device did the engineer install?
Answer:
The engineer installed a Bridge
Explanation:
A bridge is a networking device that serves as a link between two or more networks, therefore, making them work as a single network. Bridges function in a similar pattern as hubs and repeaters, however, they are distinct. The MAC address table is maintained to adequately direct transmissions to the receiver.
It is worthy to note that bridges operate on the Data link layer of the OSI (Open system Interconnect) model. It connects and maintains communication between multiple networks.
The bridge installed by the engineer creates stability between the two network segments. It optimizes the signal which makes the network perform better.

___ transmission systems transmit tightly focused beams of radio signals from one ground-based microwave transmission antenna to another.
Answer:
Terrestrial microwave
Explanation:
Based on the information provided it can be said that the type of transmission system being described is called a Terrestrial microwave transmission systems. This is a system used between ground-based microwave transmission antennas which produce a narrow, highly directional signal to another antenna in order to communicate information back and forth. Although very effective, it limits the communication to only the antenna's that have a line-of-sight with each other.
Option d is correct. The correct answer is terrestrial microwave. Terrestrial microwave transmission systems are used for long-distance land-based communications, requiring clear line-of-sight between the antennas due to their high-frequency, short wavelength signals.
These systems require a clear line of sight between the transmitting and receiving antennas due to the short wavelengths of microwave signals, making them suitable for long-distance land-based communications.Microwaves, due to their high frequencies, can carry more information per unit time. This efficiency makes them ideal for both land-based long-distance communications and satellite transmissions. However, unlike cellular systems which use weaker radio transmitters for short distances, terrestrial microwave systems focus on long-distance transmission between antennas.Hence,option d is correct.
