For 1.
Positive correlation means if you plot a country's population and land size on a graph. There would be a linear regression line that's sloping upwards.
Since it's a scatterplot, there will be some that fall out of the line, but most of them should be on the line.
It's (A)
For 2.
An outlier is a datapoint that's far, FAR away from the others, so it's (B)
For 3. (A), it's a single line-of-best fit that runs through the middle of the cluster of data points.
COMPLETE QUESTION
I. public class Test {
public static void main(String[] args){
System.out.println("Welcome to Java!");
}
}
II. public class Test { public static void main(String[] args) {System.out.println("Welcome to Java!");}}
Answer:
Both codes will compile and run and display Welcome to Java, but the code in II has a better style than I
Explanation:
When written codes, paying attention to proper coding styles and efficient memory management enables us to create programs that are highly efficient, coding styles refer to proper indentions and avoiding too lenghty lines of code (as is in code I), adding approprite comments etc.
Answer:
product_name = input("Enter product name : ")
if product_name=="pen"or"book"or"box"or"pencil"or"eraser":
if product_name == "pen":
amount = 10
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "book":
amount = 100
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "box":
amount = 150
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "pencil":
amount = 5
print(f"Product Name: {product_name}\nCost: {amount} rupees")
if product_name == "eraser":
amount = 8
print(f"Product Name: {product_name}\nCost: {amount} rupees")
else:
print("Item not found!")
Explanation:
The python program is a code of nested if-statements that compares the input string to five items of the first if-statement. For every item found, its code block is executed.
Answer:
TLS
Explanation:
In the field of computer security, TLS refers to Transport Layer Security it is closely related to the Secure Sockets Layer (SSL) although TLS is more commonly used these days. They are both techniques in cryptography that provides for the safe transfer of information between two parties (servers, systems and user applications)
TLS particularly provides a balance between transmission speed and data security through the use of symetric and asymmetric cryptography and the encryption and decryption key is the session key at both ends (sender and reciever), as such TLS has found usage in most advanced data exchange systems like credit card processing and online banking.
