Answer:
There are many factors that cause aggregate demand to shift from AD to AD1. The unemployment rate will fall and inflation will increase.
<u>Explanation:</u>
A Shift in aggregate demand from AD to AD1 means there has been a fall in demand. Various factors that cause demand to decrease are:
- Increase in price of a good itself
- Increase in the price of complimentary goods-This will lead to a fall in demand. Like ink and pen are complementary goods. if the Price of ink increases then demand for pen will decrease.
- A Decrease in the price of substitute goods-Like tea and coffee.
- Expectation regarding future fall in price
So due to the decrease in demand finally the unemployment will increase and with that, the inflation rate will increase making things dearer.
Answer:
import java.util.Scanner;
public class TestClock {
public static void main(String[] args) {
Scanner in = new Scanner (System.in);
System.out.print("Enter favorite color:");
String word1 = in.next();
System.out.print("Enter pet's name:");
String word2 = in.next();
System.out.print("Enter a number:");
int num = in.nextInt();
System.out.println("you entered: "+word1+" "+word2+" "+num);
}
}
Explanation:
Using Java Programming language
- Import the Scanner class
- create an object of the scanner class
- Prompt user to enter the values for the variables (word1, word2, num)
- Use String concatenation in System.out.println to display the output as required by the question.
Answer:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take 
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0
