Answer:
Let P(x) = x is in the correct place
Let Q(x) = x is in the excellent place
R(x) denotes the tool
Explanation:
a) Something is not in the correct place.
P(x) is that x is in the correct place so negation of ¬P(x) will represent x is not in the correct place. ∃x is an existential quantifier used to represent "for some" and depicts something in the given statement. This statement can be translated into logical expression as follows:
∃x¬P(x)
b) All tools are in the correct place and are in excellent condition.
R(x) represents the tool, P(x) represents x is in correct place and Q(x) shows x is in excellent place. ∀ is used to show that "all" tools and ∧ is used here because tools are in correct place AND are in excellent condition so it depicts both P(x) and Q(x). This statement can be translated into logical expression as follows:
∀ x ( R(x) → (P(x) ∧ Q(x))
c) Everything is in the correct place and in excellent condition.
Here P(x) represents correct place and Q(x) represents excellent condition ∀ represent all and here everything. ∧ means that both the P(x) and Q(x) exist. This statement can be translated into logical expression as follows:
∀ x (P(x) ∧ Q(x)
Answer:
Explanation:
import java.Util;
public class Eggs{
public static void main (String [] args)
{
int noOfEggs, dozen, units;
float total;
Scanner input = new Scanner(System.in);
noOfEggs = input.nextInt();
if(noOfEggs < 0)
{
System.out.print("Invalid");
}
else
{
if(noOfEggs >= 12)
{
dozen = noOfEggs/12;
units = noOfEggs % 12;
}
else
{
dozen = 0;
units = noOfEggs;
}
total = dozen * 3.25 + (units * 45)/100;
System.out.print("You ordered "+noOfEggs+" eggs.\n");
System.out.print("That's "+dozen+" dozen at $3.25 per dozen and "+units+" loose eggs at 45 cents each for a total of $"+total);
}
}
}
Answer:
The above statement is FALSE
Augmented reality works with sensor based inputs from the real world.
It is an immersive perception of a real-world environment in which objects existing in the real world are augmented by computer-generated perceptual knowledge, often through multiple sensory modalities like visual, auditory, haptic, somatosensory and olfactory.
Based on the above description
Answer:
x=2
x=1
x=2
Explanation:
a)
This if statement if (1+2=3) checks if the addition of two numbers 1 and 2 is true. Here the addition of 1 and 2 is 3 which is true. So the condition becomes true.
Since the condition is true x:=x+1 statement is executed. This statement means that the value of x is incremented by 1.
The value of x was 1 before the if statement is reached. So x:=x+1 statement will add 1 to that value of x.
x:=x+1 means x=x+1 which is x=1+1 So x=2
Hence value of x is 2 (x=2) after the execution of x:=x+1
b)
In statement b the value of x will be 1 because both the mathematical operations in the if statement evaluate to false.
which means in b, x:=x+1 will not be executed and value of x remains unchanged i.e x=1
In (c) the value x will be 2 because the condition in the if statement is true. Both mathematical expressions 2+3=5 and 3+4=7 are true. Therefore x:=x+1 will be executed and value of x will be incremented by 1. Hence x=2
