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 tails for the eight tosses. The program will then print out the total number and percentages of heads and tails. Use the increment operator to increment the number of tosses as each toss is input. For example, a possible sample dialog might be: For each coin toss enter either ‘h’ for heads or ‘t’ for tails. First toss: h Second toss: t Third toss: t Fourth toss: h Fifth toss: t Sixth toss: h Seventh toss: t Eighth toss: t Number of heads: 3 Number of tails: 5 Percent heads: 37.5 Percent tails: 62.5
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))

Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times:_____.
1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle
2. Convert the angle from degrees to radians, say Rangle
3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and
4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle).
You can then visually verify if the result printed is 1 (or close to it).
Hint: angle_in_radians = (angle_in_degrees * Pi)/180
Answer:
Written in Python
import math
import random
Dangle = random.randint(0,181)
pi = 22/7
Rangle = Dangle * pi/180
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
Result = Rsin**2 + Rcos**2
print("Result = "+str(Result))
Explanation:
The next two lines import math and random library respectively
import math
import random
This line generates a random integer between 0 and 180
Dangle = random.randint(0,181)
This line initializes pi to 22/7
pi = 22/7
This line converts angle to radians
Rangle = Dangle * pi/180
The next two lines calculate the sin and cosine of the angle in radians
Rsin = math.sin(Rangle)
Rcos = math.cos(Rangle)
This line implements sin^2 theta + cos^2 theta
Result = Rsin**2 + Rcos**2
This line prints the required Result
print("Result = "+str(Result))

Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130 50 130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray

The following iteration checks for the smallest for red, green, blue
if(red <= blue && red <= green){
smallest = red;
}
else if(green <= red && green <= blue){
smallest = green;
}
else{
smallest = blue;
}
This line prints the required output
System.out.print((red - smallest)+" "+(green - smallest)+" "+(blue - smallest));

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. You are to rewrite this switch statement as one nested 150 CHAPTER 4: Selection Statements if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.
ranforce = randi([0, 12]); switch ranforce case 0 disp('There is no wind') case {1,2,3,4,5,6} disp('There is a breeze') case {7,8,9} disp('This is a gale') case {10,11} disp('It is a storm') case 12 disp('Hello, Hurricane!') end
Answer:
ranforce = randi([0, 12]);
if (ranforce == 0)
disp('There is no wind')
else if(ranforce>0 && ranforce <7)
disp('There is a breeze')
else if(ranforce>6 && ranforce <10)
disp('This is a gale')
else if(ranforce>9 && ranforce <12)
disp('It is a storm')
else if(ranforce==12)
disp('Hello, Hurricane!')
end
Explanation:
Replace all switch case statements with if and else if statements.
An instance is:
case {7,8,9}
is replaced with
else if(ranforce>9 && ranforce <12)

Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Ex: If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.
Answer:
The Following are the code to this question:
def cost(miles, milesPerGallon, dollarsPerGallon):##defining a method cost that accepts three parameter
return miles / milesPerGallon * dollarsPerGallon# calculate cost and return it value
milesPerGallon = float(input('Enter miles/Gallon value: '))#defining variable milesPerGallon for user input
dollarsPerGallon = float(input('Enter dollars/ Gallon value: '))#defining variable dollarsPerGallon for user input
print('{:.5f}'.format(cost(10, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.5f}'.format(cost(50, milesPerGallon, dollarsPerGallon)))#call method and print its value
print('{:.3f}'.format(cost(400, milesPerGallon, dollarsPerGallon)))#call method and print its value
Output:
Enter miles/Gallon value: 20.0
Enter dollars/ Gallon value: 3.1599
1.57995
7.89975
63.198
Explanation:
In the above-given code, a method "cost" is defined, that accepts three value "miles, milesPerGallon, and dollarsPerGallon" in its parameter, and use the return keyword for calculating and return its value.
In the next step, two variable "milesPerGallon, and dollarsPerGallon" is declared, that use the input method with float keyword for input floating-point value.
After input value, it uses a print method with different miles values, which are "10,50, and 400", and input value to pass in cost method to call and print its return value.

Easter Sunday is the first Sunday after the first full moon of spring. To compute the date, you can use this algorithm, invented by the mathematician Carl Friedrich Gauss in 1800:
1. Let y be the year (such as 1800 or 2001).
2. Divide y by 19 and call the remainder a. Ignore the quotient.
3. Divide y by 100 to get a quotient b and a remainder c.
4. Divide b by 4 to get a quotient d and a remainder e.
5. Divide 8 * b 13 by 25 to get a quotient g. Ignore the remainder.
6. Divide 19 * a b - d - g 15 by 30 to get a remainder h. Ignore the quotient.
7. Divide c by 4 to get a quotient j and a remainder k.
8. Divide a 11 * h by 319 to get a quotient m. Ignore the remainder.
9. Divide 2 * e 2 * j - k - h m 32 by 7 to get a remainder r. Ignore the quotient.
10. Divide h - m r 90 by 25 to get a quotient n. Ignore the remainder.
11. Divide h - m r n 19 by 32 to get a remainder p. Ignore the quotient.
Then Easter falls on day p of month n. For example, if y is 2001:
a = 6 h = 18 n = 4
b = 20, c = 1 j = 0, k = 1 p = 15
d = 5, e = 0 m = 0
g = 6 r = 6
Therefore, in 2001, Easter Sunday fell on April 15. Write a program that prompts the user for a year and prints out the month and day of Easter Sunday.

Write some code that assigns True to the variable is_a_member if the value assigned to member_id can be found in the current_members list. Otherwise, assign False to is_a_member. In your code, use only the variables current_members, member_id, and is_a_member.
Answer:
current_members = [28, 0, 7, 100]
member_id = 7
if member_id in current_members:
is_a_member = True
else:
is_a_member = False
print(is_a_member)
Explanation:
Although it is not required I initialized the current_members list and member_id so that you may check your code.
After initializing those, check if member_id is in the current_members or not using "if else" structure and "in" ("in" allows us to check if a variable is in a list or not). If member_id is in current_members, set the is_a_member as True. Otherwise, set the is_a_member as False.
Print the is_a_member to see the result
In the example above, since 7 is in the list, the is_a_member will be True

Explanation:
Continuous Improvement is a set of processes many companies use to evaluate and improve their overall operations on an ongoing basis. Usability testing Continuous Improvement Analytics System implementation.
What is Continuous Improvement?W. Edwards Deming used the phrase "continuous improvement" to refer to general processes of improvement and to embrace "discontinuous" improvements, or many diverse ways addressing various topics.
A subset of continuous improvement, with a more narrow focus on linear, incremental change inside an already-existing process, is continuous improvement.
Some practitioners also believe that statistical process control techniques are more closely related to continuous improvement. Constant improvement, often known as continuous improvement, is the continued enhancement of goods, services, or procedures through both small-scale and significant advancements.
Therefore, Continuous Improvement is a set of processes many companies use to evaluate and improve their overall operations on an ongoing basis. Usability testing Continuous Improvement Analytics System implementation.
