A primary key ensures that —- are unique ?
Answer:
To qualify as a primary key, it is the data within each column that must be unique, not simply the column names themselves. At the same time, no value in the columns can be blank or NULL. A primary key, therefore, is used to ensure the data in a specific column is unique.

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.

Answer:
The following classifications can be made of the computer systems:
1. According to size.
2. Functionality based on this.
3. Data management based.
Explanation:
Servers:-
Servers are only computers that are configured to offer clients certain services. Depending on the service they offer, they are named. For example security server, server database.
Workstation:-
These are the computers which have been designed mainly for single users. They operate multi-user systems. They are the ones we use for our daily business/personal work.
Information appliances:-
They are portable devices that perform a limited number of tasks such as basic computations, multimedia playback, internet navigation, etc. They are commonly known as mobile devices. It has very limited storage and flexibility and is usually "as-is" based.
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)
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

H-Br bond is polar, hydrogen is partly positive and bromine is partly negative
H-Cl bond is polar, hydrogen is partly positive and bromine is partly negative
O-H bond in water is polar, hydrogen is partly positive and oxygen is partly negative
C-O bond in CH40 is polar, carbon is partly positive and oxygen is partly negative
Explanation:
A molecule possess a dipole moment when there is a large difference in electro negativity between two bonding atoms in the molecule.
The presence of dipole moments introduces polarity to the molecule. In all the molecules listed in the answer, the shared electron pair of the bond is closer to the more electronegative atom causing it to be partially negative while the less electronegative atom in the bond is partially positive.
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.

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.

If the code for JAVA is LCXC, what is the code for BASIC?
Answer:
DCUKE
Explanation:
Given that,
Code for JAVA = LCXC
To find,
Code for BASIC = ?
As we observe the pattern,
In "JAVA", every letter moved two-letter forward in their alphabetical order or we can say that every third alphabet of the given letter is used to make the code:
J + 2 = L
A + 2 = C
V + 2 = X
A + 2 = C
Similarly,
B + 2 = D
A + 2 = C
S + 2 = U
I + 2 = K
C + 2 = E
Thus, DCUKE is the code for BASIC.
The code for BASIC given the code for JAVA is; DCUKE
We are given the code for JAVA as LCXC
From that code for "JAVA", we see that every letter is moved forward two letters in their alphabetical order. This means
J = L because L comes after J and KA = C because C comes after A and BV = X because X comes after V and UA = C because C comes after A and BSimilarly for BASIC;
B = D because D comes after B and CA = C because C comes after A and BS = U because U comes after S and TI = K because K comes after I and JC = E because E comes after C and DThus, finally the code for BASIC is DCUKE

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.
