Concept explainers
To round numbers to specific decimal places, use a statement like
double y = Math.floor(x * 10 + 0.5) / 10;
which rounds x to the tenths position (i.e., the first position to the right of the decimal point), or
double y = Math.floor(x * 100 + 0.5) / 100;
which rounds x to the hundredths position (i.e., the second position to the right of the decimal point). Write an application that defines four methods for rounding a number x in various ways:
- 1. roundTolnteger(number)
- 2. roundToTenths(number)
- 3. roundToHundredths(number)
- 4. roundToThousandths(number)

- (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. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.arrow_forwardThe cost of renting a room at a hotel is, say $100.00 per night. For special occasions, such as a wedding or conference, the hotel offers a special discount as follows: If the number of rooms booked at least 10, the discount is 10%; at least 20, the discount is 20%; and at least 30, the discount is 30%. Also if rooms are booked for at least three days, then there is an additional 5% discount. Write a program that prompts the user to enter the cost of renting one room, the number of rooms booked, the number of days the rooms are booked, and the sales tax (as a percent). The program outputs the cost of renting one room, the discount on each room as a percent, the number of rooms booked, the number of days the rooms are booked, the total cost of the rooms, the sales tax, and the total billing amount. Your program must use appropriate named constants to store special values such as various discounts.arrow_forwardTo make telephine numbers easier to remember, some companies use letters to show their telephone number. For example, the telephine number 438-5626 can be shown as GET-LOAN. In some cases, to make a telephone number meaningful, compaines might use more than seven letters. For example, 225-5466, can be displayed as CALL-HOME, whic uses eight letters. Write a program that prompts the user to enter a telephone number expressesd in letters and outputs the corresponding telephone number in digits. If the user enters more than seven letter, then process only the first seven letters. Also, output the -(hyphen) after the third digit. Allow the user to use uppercase and lowercase letters, as well as spaces between words. Moreover, your program should proces as many telephone as the user wants. (Hint: You can read the entered telephine number as a string and then use the charAt() to extract each character.)arrow_forward
- Question # 4: Write a program that calculates the electricity bill. The rates of electricity per unit are as follows: If the units consumed are 300 and 8 2000 2750 Question # 6: Write a program that converts the angle from degree to radian and displays each value.arrow_forwardA complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1) The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas: a + bi + c + di = (a+c) + (b+d)i (addition) a + bi − (c + di) = (a−c) + (b−d)i (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i (multiplication) (a + bi) / (c + di) = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2) (division) You can obtain the Absolute Value for a complex number using the following formula: |a + bi| = √(a2 + b2) A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.

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…arrow_forward
- In PyCharm, write a program that prompts the user for their name and age. Your program should then tell the user the year they were born. Here is a sample execution of the program with the user input in bold: What is your name? Amanda How old are you? 15 Hello Amanda! You were born in 2005. Hello Amanda! You were born in 2005. Write the program. Format your code using best practices. Refer to the zyBooks style guide, if needed, to use proper naming conventions for variables and methods. Use the most appropriate statements with minimal extraneous elements, steps, or procedures. Run the program. Debug the program. Be sure your code produces the correct results. Save and submit your file.arrow_forwardThe owners of the Annan Supermarket would like to have a program that computes the weekly gross pay of their employees. The user will enter an employee’s first name, last name, the hourly rate of pay, and the number of hours worked for the week. In addition, Annan Supermarkets would like the program to compute the employee’s net pay and overtime pay. Overtime hours, any hours over 40, are paid at 1.5 the regular hourly rate. Net pay is gross pay minus taxes (Refer to the tax table on the second page). Define a class called Employee. The class must have private attributes to store the employee's name, hourly rate, and regular (≤ 40) and overtime hours worked. The class must also have methods to perform the following tasks: A constructor to initialize the hourly rate to the minimum wage of $7.25 per hour and the hours worked (regular and overtime) to 0.0. A method to get (a setter/mutator method)⬧ the employee's name⬧ the hourly rate⬧ the hours work for the month (by the week –…arrow_forwarduse C++ programming language Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an inpatient or an outpatient. If the patient was an inpatient, the following data should be entered: The number of days spent in the hospital The daily rate Charges for hospital services (lab tests, etc.) Hospital medication charges If the patient was an outpatient, the following data should be entered: Charges for hospital services (lab tests, etc.) Hospital medication charges Use a single, separate function to validate that no input is less than zero. If it is, it should be reentered before being returned. Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient data. Both functions should return the…arrow_forward
- (Geometry: point in a circle?) Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the circle centered at (0, 0) withradius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, asshown in Figure 3.7a.(Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10.The formula for computing the distance is 2(x2 - x1)2 + (y2 - y1)2. Test yourprogram to cover all cases.)
