A soft drink company recently surveyed 16,500 of its customers and found that approximately 15 percent of those surveyed purchase one or more energy drinks per week. Of those customers who purchase energy drinks, approximately 58 percent of them prefer citrus-flavored energy drinks. Write a program that displays the following: - The approximate number of customers in the survey who purchase one or more energy drinks per week - The approximate number of customers in the survey who prefer citrus-flavored energy drinks

Write a program that has variables to hold three test scores. The program should ask the user to enter three test scores and then assign the values entered to the variables. The program should display the average of the test scores and the letter grade that is assigned for the test score average. Use the grading scheme in the following table:

A soft drink company recently surveyed 16,500 of its customers and found that approximately 15 percent of those surveyed purchase one or more energy drinks per week. Of those customers who purchase energy drinks, approximately 52 percent of them purchase citrus flavored energy drinks. Write a program that displays the following:

• The approximate number of customers in the survey who purchase one or more energy drinks per week.
• The approximate number of customers in the survey who purchase citrus flavored energy drinks.

Miller (2008) examined the energy drink consumption of college undergraduates and found that males use energy drinks significantly more often than females. To further investigate this phenomenon, suppose that a researcher selects a random sample of n = 36 male undergraduates and a sample of n = 25 females. On average, the males reported consuming M = 2.45 drinks per month and females had an average of M = 1.28. Assume that the overall level of consumption for college undergraduates averages $\mu=1.85$ energy drinks per month, and that the distribution of monthly consumption scores is approximately normal with a standard deviation of $\sigma=1.2$.

a. Did this sample of males consume significantly more energy drinks than the overall population average? Use a one-tailed test with $\alpha=.01$.

b. Did this sample of females consume significantly fewer energy drinks than the overall population average? Use a one-tailed test with $\alpha=.01$.

A car holds 15 gallons of gasoline and can travel 375 miles before refueling. Write a program that calculates the number of miles per gallon the car gets. Display the result on the screen. Hint: Use the following formula to calculate miles per gallon (MPG): MPG Miles Driven/Gallons of Gas Used

Which of the following is true about energy drinks and mixers:
a. carbonation generally slows the rate of alcohol absorption
b. a sweet taste can hide the taste of alcohol
c. caffeine helps keep the person aware of how intoxicated he or she is
d. all of the above?

Write a program that computes the tax and tip on a restaurant bill for a patron with a $88.67 meal charge. The tax should be 6.75 percent of the meal cost. The tip should be 20 percent of the total after adding the tax. Display the meal cost, tax amount, tip amount, and total bill on the screen.

One acre of land is equivalent to 43,560 square feet. Write a program that calculates the number of acres in a tract of land with 391,876 square feet.

One acre of land is equivalent to 43,560 square feet. Write a program that asks the user to enter the total square feet in a tract of land and calculates the number of acres in the tract. Hint: Divide the amount entered by 43,560 to get the number of acres.

You have been given a job as a programmer on a Cyborg supercomputer. In order to accomplish some calculations, you need to know how many bytes the following data types use: char, int, float, and double. You do not have any manuals, so you can’t look this information up. Write a C++ program that will determine the amount of memory used by these types and display the information on the screen.

In the United States, land is often measured in square feet. In many other countries, it is measured in square meters. One acre of land is equivalent to 43,560 square feet. A square meter is equivalent to 10.7639 square feet. Write a program that computes and displays the number of square feet and the number of square meters in 1/2 acre of land.

Hint: Because a square meter is larger than a square foot, there will be fewer square meters in 1/2 acre than there are square feet.

The East Coast sales division of a company generates 58 percent of total sales. Based on that percentage, write a program that will predict how much the East Coast division will generate if the company has $8.6 million in sales this year.

Describe in words how to take a partial derivative.
