Scenario
As you surely know, due to some astronomical reasons, years may be leap or common. The former
are 366 days long, while the latter are 365 days long.
Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the
kind of year:
if the year number isn't divisible by four, it's a common year,
otherwise, if the year number isn't divisible by 100, it's a leap year.
otherwise, if the year number isn't divisible by 400, it's a common year.
otherwise, it's a leap year.
none of the above
year int(input("enter the year"))
if (year%4 1-0) and (year%400 -0) or (year % 1000):
print (year is common year")
else:
print(year, is leap year")
year= int(input ("enter the year"))
if (years !-0) or (year480 1-0) and (year % 1001-0):

Suppose you want to deposit a certain amount of money into a savings account, and thenleave it alone to draw interest for the next 10 years. At the end of 10 years, you would like tohave $10,000 in the account. How much do you need to deposit today to make that happen?You can use the following formula, which is known as the present value formula, to find out:The terms in the formula are as follows: [5 marks]• P is the present value, or the amount that you need to deposit today.• F is the future value that you want in the account. (In this case, F is $10,000.)• r is the annual interest rate.• n is the number of years that you plan to let the money sit in the account.Write a method named presentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years asarguments. It should return the present value, which is the amount that you need to deposit today.Demonstrate the method in a program that lets the user experiment with…

- USE PYTHON Source: en.wikipedia.org/wiki/Camel_case In some languages, it’s common to use camel caseLinks to an external site. (otherwise known as “mixed case”) for variables’ names when those names comprise multiple words, whereby the first letter of the first word is lowercase but the first letter of each subsequent word is uppercase. For instance, whereas a variable for a user’s name might be called name, a variable for a user’s first name might be called firstName, and a variable for a user’s preferred first name (e.g., nickname) might be called preferredFirstName. Python, by contrast, recommendsLinks to an external site. snake caseLinks to an external site., whereby words are instead separated by underscores (_), with all letters in lowercase. For instance, those same variables would be called name, first_name, and preferred_first_name, respectively, in Python.

In this assignment, you are asked to design and implement a program that writes out what bills (ones, fives, tens, twenties) and coins (pennies, nickels, dimes, and quarters) that should be returned to the customer given two inputs from the user: A total cost of a sale.

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 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.arrow_forward

Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)arrow_forward
- (Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:arrow_forward(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9.

Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.arrow_forward(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation.

Specifically, they are awarded 5 stars for each point scored, and 3 stars are taken away for each foul committed. For every player, the number of points that they score is greater than the number of fouls that they commit. Your job is to determine how many players on a team have a star rating greater than 40. You also need to determine if the team is considered a gold team which means that all the players have a star rating greater than 40.
