Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)
Mnenie [13.5K]

Answer:

(1)Minterms complement = XYZ (2) Compliment of Minterms = Σm(0,1, 2 , 4 , 6) (3) (X+Y+Z) (4) Minimized SOP = Z + XY

Manterms = πM

Explanation:

Solution

Recall that:

Given the function F (X, Y , Z)=Σm(0,1, 2 , 4 , 6)

(1) Canonical Disjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as minterms

In Minterm we assign 'I' to each uncomplimented variable and '0' to each complemented/complementary variable

For the given question stated we ave the following:

Minterms = XYZ, XYZ, XYZ, XYZ, XYZ.

(2) Canonical Conjunctive Normal Form: In boolean algebra, the boolean function can be expressed as Canonical Disjunctive form known as maxterms.

In Maxterms we assign '0' to each uncomplimented variable and '1' to each complemented/complementary variable

Compliment of Minterms = Σm(0,1, 2 , 4 , 6)

Maxterms = πM

  • A person with technical or hard skills is able to apply specific methods, procedures and techniques in a specialized field.

  • Soft skills refers to the characteristics and personal competencies that show how a person copes with others, it is related to emotional intelligence.

Therefore, we can conclude that technical or hard skills are the practical knowledge necessary to perform specific tasks, while soft skills are those skills associated with the ability to interact effectively on a personal level.

I need help with completing this python code.Complete the Car class by creating an attribute purchase_price (type int) and the m
netineya [11]

Answer:

class Car:

   def __init__(self):

       self.model_year = 0

       # TODO: Declare purchase_price attribute

       self.purchase_price = 0

       self.current_value = 0

   def calc_current_value(self, current_year):

       depreciation_rate = 0.15

       # Car depreciation formula

       car_age = current_year - self.model_year

       self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age)

# TODO: Define print_info() method to output model_year, purchase_price, and current_value

   def print_info(self):

       print("Model year: ",self.model_year)

       print("Purchase year: ",self.purchase_price)

       print("Current value: ",self.current_value)

def main():

   year = int(input())

   price = int(input())

   current_year = int(input())

   my_car = Car()

   my_car.model_year = year

   my_car.purchase_price = price

   my_car.calc_current_value(current_year)

   my_car.print_info()

if __name__ == "__main__":

   main()

Explanation:

The Car class in the python program is used to create a car object instance with class methods model_year, purchase_price, and calc_current_value, which accepts as arguments, year, price and current_year respectively. The main function runs if only the python module is run and interpreted to print out the year and current price of a car object instance defined.
