Write a C++ program that reads a number and determines whether the number is positive, negative or zero using Switch operator method
Answer:
#include <iostream>
using namespace std;
template <typename T> int sgn(T val) {
return (T(0) < val) - (val < T(0));
}
int main()
{
cout << "Enter a number: ";
int number;
cin >> number;
switch (sgn(number)) {
case -1: cout << "The number is negative";
break;
case 0: cout << "The number is zero";
break;
case 1: cout << "The number is positive";
break;
}
}
Explanation:
You need the special sgn() function because a switch() statement can only choose from a list of discrete values (cases).

Answer:
D. Iterative design
Explanation:
An iterative design can be defined as a cyclic process which typically involves prototyping, testing, evaluating or analyzing and refining of a product, so as to continually improve the product.
In an iterative design process, the following steps are adopted;
1. A prototype of the product is first created and tested by the manufacturer.
2. The product is then evaluated to check for any defect or flaw.
3. The defect or flaw is fixed through a refining process.
4. The previous steps are repeated incrementally until an improved version of the product is created.
Hence, cycling through the design process to create several models that incrementally improve a solution is called iterative design.
Answer:
Iterative Design
Explanation:
A. It seeks to figure what it defective
B. It reaffirms if all requirements are met to solve a problem
C. It's main goal was to avoid excess products that might not end up making sales in the near future
D. Making several revision on problems to take out an efficient solution
D makes the most sense here.
You trained a binary classifier model which gives very high accuracy on thetraining data, but much lower accuracy on validation data. The following maybe true:
a. This is an instance of overfitting.
b. This is an instance of underfitting.
c. The training was not well regularized.
d. The training and testing examples are sampled from different distributions.
Answer:
a. This is an instance of overfitting.
Explanation:
In data modeling and machine learning practice, data modeling begins with model training whereby the training data is used to train and fit a prediction model. When a trained model performs well on training data and has low accuracy on the test data, then we say say the model is overfitting. This means that the model is memorizing rather Than learning and hence, model fits the data too well, hence, making the model unable to perform well on the test or validation set. A model which underfits will fail to perform well on both the training and validation set.

Which of the following Python methods is used to perform hypothesis testing for a population mean when the population standard deviation is unknown?
a. uttest(dataframe, null hypothesis value)
b. ztest(dataframe, null hypothesis value)
c. prop_1samp_hypothesistest(dataframe, n, alternative hypothesis value)
d. ttest_1samp(dataframe, null hypothesis value)
Answer:
B: ztest(dataframe, null hypothesis value)
The Python method that is used to perform a test of hypothesis for a population mean with an unknown population standard deviation is d. ttest_1samp(dataframe, null hypothesis value).
A t-test is normally applied when the population standard deviation is not known. The researcher will use the sample standard deviation.While the z-test can also be used in Python to perform hypothesis testing with a known population standard deviation and a sample size that is larger than 50, only the t-test can be applied with an unknown population standard deviation or a sample size less than 50.Thus, the only Python method to carry out hypothesis testing with unknown population standard deviation is the t-test, which is given in option d.

What appears to be the trend in these newer protocols?
Answer:
As compared to new multiplexing techniques, older techniques like FDM frequency-division multiplexing (FDM) may be a technique by which the entire bandwidth available during a communication medium is split into a series of non-overlapping frequency sub-bands, each of which is employed to hold a separate signal.
Explanation:
Especially used for Radio and tv Broadcasting and TDM ( Time-division multiplexing (TDM) may be a method of transmitting and receiving independent signals over a standard signal path by means of synchronized switches at each end of the cable in order that each signal appears on the road only a fraction of your time in an alternating pattern, especially used for telegraphy) are simple; they'll be suffering from noise and their transmission speeds are high. New techniques are far more complex, they will be suffering from more noise and transmission speeds are very high as compared to older techniques.

Explanation:
Create a method called nicknames that passes an array as a parameter. Inside the method initialize it to hold 5 names of your choice. Use the for each enhanced loop to print the elements of the array.
//======METHOD DECLARATION=========//
//method name: nicknames
//method return type: void
//method parameter: an array reference
public static void nicknames(String [] names){
//initialize the array with 5 random names
names = new String[] {"John", "Doe", "Brian", "Loveth", "Chris"};
//using an enhanced for loop, print out the elements in the array
for(String n: names){
System.out.print(n + " ");
}
}
Explanation:
The program is written in Java. It contains comments explaining important parts of the code. Kindly go through these comments.
A few things to note.
i. Since the method does not return any value, its return type is void
ii. The method is made public so that it can be accessible anywhere in and out of the class the uses it.
iii. The method is made static since it will most probably be called in the static main method (at least for testing in this case)
iv. The method receives an array of type String as parameter since the names to be stored are of type String.
v. The format of initializing an array manually should follow as shown on line 7. The new keyword followed by the array type (String), followed by the square brackets ([]) are all important.
vi. An enhanced for loop (lines 9 - 11) is a shorthand way of writing a for loop. The format is as follows;
=> The keyword for
=> followed by an opening parenthesis
=> followed by the type of each of the elements in the array. Type String in this case.
=> followed by a variable name. This holds an element per cycle of the loop.
=> followed by a column
=> followed by the array
=> followed by the closing parenthesis.
=> followed by a pair of curly parentheses serving as a block containing the code to be executed in every cycle of the loop. In this case, the array elements, each held in turn by variable n, will be printed followed by a space.
A complete code and sample output for testing purposes are shown as follows:
==================================================
public class Tester{
//The main method
public static void main(String []args){
String [] names = new String[5];
nicknames(names);
}
//The nicknames method
public static void nicknames(String [] names){
names = new String[] {"John", "Doe", "Brian", "Loveth", "Chris"};
for(String n: names){
System.out.print(n + " ");
}
}
}
==================================================
Output:John Doe Brian Loveth Chris
NB: To run this program, copy the complete code, paste in an IDE or editor and save as Tester.java

you recieve a phone call from the sterlization monitoring company informing you that the last spore test you sent has failed. What should you check to determine the possible cause
Answer: The type sterilization that was used and how well it was performed
Explanation:
If there's a phone call from the sterilization monitoring company that the last spore test sent has failed, to determine the possible cause, I'll have to type sterilization that was used and how well it was performed.
The sterilization technique used will be analysed, and there'll also be a check for possible human errors. Once thus is done, the possible reason for the failure of the last spore that was sent can then be determined.
spherevolume = (4.0 / 3.0) * pival * sphereradius * sphereradius * sphereradius ;
Answer:
The program in Python is as follows:
pival = 3.142
sphereradius = float(input("Radius: "))
spherevolume = [tex](4.0 / 3.0)[/tex] * [tex]pival[/tex] * sphereradius * [tex]sphereradius[/tex] * sphereradius
print(spherevolume)
Explanation:
The missing part of the program is to calculate the volume of a sphere.
The program in Python (in the answer section) is implemented using the already used variables.
Initialize pi
pival = 3.142
Get input for radius
sphereradius = float(input("Radius: "))
Calculate the volume
spherevolume = [tex](4.0 / 3.0)[/tex] * [tex]pival[/tex] * sphereradius * [tex]sphereradius[/tex] * sphereradius
Print the calculated volume
print(spherevolume)
Consider a file system using the indexed allocation. The block size is 512 bytes and the pointer to a block takes 2 bytes. The largest file size that a one level indexed allocation method could handle is ___________ KB. Recall that 1KB is equal to 210 bytes. Answer -1 if there is no limit based on the provided information.
Answer:
128 KB
Explanation:
Given data :
The block size = 512 bytes
Block pointer size = 2 bytes
In an indexed allocation, a special block named Index Block contains all the pointers to the blocks that the file had occupied.
Therefore, the maximum number of block pointer in 1 block :
[tex]$=\frac{\text{block size}}{\text{pointer size}}$[/tex]
[tex]$=\frac{512}{2}$[/tex]
= 256
Thus, a block can hold maximum 256 pointers.
It is given the level of indexing is one. So,
Maximum size of the file = maximum number of block pointers in 1 file x block size
= 256 x 512
[tex]$=2^8 \times 2^9$[/tex]
[tex]$=2^{8+9}$[/tex]
[tex]$=2^{17}$[/tex]
[tex]$=2^7 \times 2^{10}$[/tex]
[tex]$=128 \times 2^{10}$[/tex]
= 128 KB (∵ 1 KB = [tex]2^{10} \ B[/tex] )
Therefore, the largest file that 1 level if indexed allocation method can handle is 128 KB.
