Translate each of these statements into logical expressions using predicates, quantifiers, and logical connectives. a) Something
yKpoI14uk [10]

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)

Give a proof for each statement.
Marrrta [24]

Answer:

  • If a group of 9 kids have won a total of 100 trophies, then at least one of the 9 kids has won at least 12 trophies.
  • If a person buys at least 400 cups of coffee in a year, then there is at least one day in which the person has bought at least two cups of coffee.
  • The average of three real numbers is greater than or equal to at least one of the numbers.

Explanation:

1)

Suppose that  each kid has less than 12 trophies

Total trophies = 100

Maximum trophies won by one kid = 11

total kids = 9

total number of trophies = 9 * 11 = 99 which contradicts the fact the total number of trophies are 100

2)

Suppose that  person has less than 2 cups of coffee a day

Total cups of coffee = 400

he has bought at least one cup of coffee each day

which means

total number of cups of coffee = 1* 366 = 366 which contradicts the fact the person buys at least 400 cups of coffee in a year

3)

Average of three number = (a+ b+ c)/3

suppose that there are real numbers a, b, and c such  that all three numbers are less than the average of the three numbers.

Let m be the average (a+b+c )/3 = m. Then our assumption states that (a < m) and  (b < m) and (c < m). By adding all the inequalities we get a + b + c < 3m. But m is  defined to be (a+b+c) /3  , so a + b + c = 3m.  But now we have that 3m = a + b + c < 3m. So 3m < 3m which is an obvious  contradiction. Thus our claim is true

   public static void main(String[] args) {

       SoccerPlayer playerOne = new SoccerPlayer("Rinco",9,16,22);

       System.out.println("The player of the season is "+playerOne.getName()+" His Jessey Number is "+playerOne.getJerseyNum()

       +" In the 2019/2020 season he scored and total of "+playerOne.getGoalsScored()+" and "+

               playerOne.getAssists()+" Asists");

   }

}

See the SoccerPlayer class with the feilds and methods (constructor, getter and setters) in the explanation section

Explanation:

public class SoccerPlayer {

   private String name;

   private int jerseyNum;

   private int goalsScored;

   private int assists;

   public SoccerPlayer(String name, int jerseyNum, int goalsScored, int assists) {

       this.name = name;

       this.jerseyNum = jerseyNum;

       this.goalsScored = goalsScored;

       this.assists = assists;

   }

   public String getName() {

       return name;

   }

   public void setName(String name) {

       this.name = name;

   }

   public int getJerseyNum() {

       return jerseyNum;

   }

   public void setJerseyNum(int jerseyNum) {

       this.jerseyNum = jerseyNum;

   }

   public int getGoalsScored() {

       return goalsScored;

   }

   public void setGoalsScored(int goalsScored) {

       this.goalsScored = goalsScored;

   }

   public int getAssists() {

       return assists;

   }

   public void setAssists(int assists) {

       this.assists = assists;

   }

}
