Write a program that will print out statistics for eight coin tosses. The user will input either an "h" for heads or a "t" for t

shusha [124]

Answer:

Written in Python

head = 0

tail = 0

for i in range(1,9):

print("Toss "+str(i)+": ")

toss = input()

if(toss == 'h'):

head = head + 1

else:

tail = tail + 1

print("Number of head: "+str(head))

print("Number of tail: "+str(tail))

print("Percent head: "+str(head * 100/8))

print("Percent tail: "+str(tail * 100/8))

Explanation:

The next two lines initialize head and tail to 0, respectively

head = 0

tail = 0

The following is an iteration for 1 to 8

for i in range(1,9):

print("Toss "+str(i)+": ")

toss = input() This line gets user input

if(toss == 'h'): This line checks if input is h

head = head + 1

else: This line checks otherwise

tail = tail + 1

The next two lines print the number of heads and tails respectively

print("Number of head: "+str(head))

print("Number of tail: "+str(tail))

The next two lines print the percentage of heads and tails respectively

print("Percent head: "+str(head * 100/8))

print("Percent tail: "+str(tail * 100/8))

Rule number one for handling an emergency is to _____. A. buy a new vehicle B. call law enforcement C. remain calm D. restart th

KengaRu [80]

Answer:

Remain calm.

Explanation:

Keeping your calm can get you through any emergency situation. Physical activity stimulates the vagus nerve (a part of the autonomic nervous system) that calms the body down, which is necessary for staying calm when under pressure. During a stressful situation, negative thoughts only work toward increasing your stress level and that is not good for your body or helpful in making effective decisions. This can help you feel like you are in control of the situation and ultimately face the emergency situation better.

Discuss briefly general-purpose graphicsprimitives that contain 2D graphics library.

Zina [86]

Answer:

General purpose graphics primitives that contain 2D graphic library as, it is used in graphics processing unit which typically manage computation for computer graphics. Graphic primitives contain basic element such as lines and curves. Modern 2D computer graphic system that operate with primitives which has lines and shapes. All the elements of graphic are formed from primitives.

What is the output of this code? import java.util.HashSet; class A { public static void main(String[ ] args) { HashSet set = new

kompoz [17]

Answer:

The code will give an error that is "At least one public class is required in main file".

Explanation:

In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:

Program:

import java.util.HashSet; //import package

public class A //define class as public.

{

public static void main(String[ ] args) //define main method.

{

HashSet set = new HashSet(); //creating hashset object.

set.add("A"); //add alphabet in hashset

set.add("B"); //add alphabet in hashset

set.add("C"); //add alphabet in hashset

System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.

}

Output:

Size of HashSet is : 3

Explanation of the program:

In the above program, we define a public class that is "A" and inside the class, we define the main method.

Inside the main method, we create a HashSet class object that is "set".

To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
