Answer:

discriminant = b * b - 4 * a * c

discriminant = b ** 2 - 4 * a * c

Explanation:

The operands are correct and in the right order (for python).

** is the operand for squaring something.

* is the operand for multiplying something.

- is the operand for subtracting something.

Let's take a look at these examples individually.

discriminant = bb - 4ac. You have to use the * sign so the computer understands that you're trying to multiply two objects together.

discriminant = b * b - 4 * a * c. This example works because it's using the * where it's appropriate.

discriminant = b ^ 2 - 4ac. In python we don't use the ^ sign. To use exponents, we use **. Also, there is no * sign in between 4, a, and c.

discriminant =  b ** 2 - 4 * a * c. This example works because it uses the ** and * sign where appropriate.

discriminant = b ^ 2 - 4 * a * c. This example uses the ^ sign and python does not support it.

Use the modulo operator (%) to get the desired rightmost digits. Ex: The rightmost 2 digits of 572 is gotten by 572 % 100, which
uranmaximum [27]

Hi, you haven't provided the programing language in which you need the code, I'll just explain how to do it using Python, and you can apply a similar method for any programming language.

Answer:

def rightMost(num):

   lenNum = len(str(num))

   rightNum = num%(10**(lenNum-1))

   print(rightNum)

   return(rightNum)

Explanation:

In this function we receive an integer number, then we find how many digits this number has, and finally, we find the rightmost digits; the main operation is modulo (takes the remainder after a division), what we want is to take all the digits except the first one, for that reason we find the modulo of the number when divided by ten to the power of the length of the number minus one, for example, if the number is 2734 we divided by 10^(4-1), where four is the length of the number, this way we get 2734/1000 and the module of it is 734.

The game begins with the player having 20 POINTS
kompoz [17]

Answer:

Following are the code to this question:

import random#import package for using random method  

def rolling_dice(): #defining method rolling_dice that uses a random number to calculate and add value in dice1 and dice2 variable

   dice1 = random.randint(1,6)

   dice2 = random.randint(1,6)

   return dice1 + dice2

def rolling(): # defining method rolling

   n_roll = 0  # defining num variable that initial value that is 0.

   p = 20 # defining variable p for looping, that points in between 1 and 59

   while p > 0 and p < 60: # defining loop that counts value dice value two times  

       d = rolling_dice()#defining d variable that hold method value

       n_roll+= 1 #defining n_roll that increment n_roll value by 1

       if d == 7 or d == 11:# defining if block that uses the d variable that checks either 7 or 11, player won d in p variable

           p+= d   # use p variable that adds d variable

       elif d == 2 or d == 3 or d == 12:#defining elif block to that checks d variable by using or operator  

           p-= d#defining d variable that decreases d variable variable

       else: # defining else block

           p1 = d # using p1 variable that store d value  

           while True:# defining loop that calculates values

               d = rolling_dice()#defining d variable that holds method values

               n_roll += 1 #increment the n_roll value by 1

               if d == 7:#defining if block that checks d value equal to 7

                   p -= p1#subtract the value of p1 in p variable  

                   break # exit loop

               elif d == p:#defining elif block to check d value is equal to p

                   p += p1#adds the value of p1 in p variable  

                   break#using break keyword

   if p<= 0:#defining if block that checks p-value is less then equal to 0  

       print('Player lost')#using print method

   elif p>= 60:#defining else block that checks p-value is greater than equal to 60

       print('Player won')#using print method to print the value

   print('number of dice rolls:', n_roll)#use print method to print n_rolls value

rolling()

Output:

Player lost

number of dice rolls: 38

Explanation:

In the above-given python code, a method "rolling_dice" is declared, inside the method two-variable "dice1 and dice2" is declared, that uses the random method to calculate the value in both variable and use the return keyword to add both values.

  • In the next step, another method the "rolling"  is declared, inside the method "n_roll and p" is declared that assigns the values and use the two while loop, inside the loop if block is defined that calculates the values.
  • In the next step, a condition block is used that stores value in the p variable and use the print method to print the "n_roll" value.
