Using Java Programing, write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: the total rainfall for the year the average monthly rainfall the month with the most rain, and the month with the least rain. Demonstrate the class in a complete program. Input Validation: Do not accept negative numbers for monthly rainfall figures.

Three of the richest comedians in the United States are Larry David (creator of Seinfeld), Matt Groening (creator of The Simpsons), and Trey Parker (co-creator of South Park). Larry David is worth $450 million more than Trey Parker. Matt Groening is worth $150 million more than Trey Parker. Combined, the net worth of these three comedians is $1650 million (or $16.5 billion). Determine how much, in millions of dollars, each of these comedians is worth.

The theory behind stars twinkling is that: A) The refractive index of the different layers of earth’s atmosphere changes continuously, consequently the position of the star’s image changes with time B) The intensity of light emitted by them changes with time C) The light from the star is scattered by the dust particles and air molecules in the earth’s atmosphere D) The distance of the stars from the earth changes with time

Rate Enhancement by Urease.The enzyme urease enhances the rate of urea hydrolysis at pH 8.0 and 20 °C by a factor of 1014. If a given quantity of urease can completely hydrolyze a given quantity of urea in 5.0 min at 20 °C and pH 8.0, how long would it take for this amount of urea to be hydrolyzed under the same conditions in the absence of urease? Assume that both reactions take place in sterile systems so that bacteria cannot attack the urea.

Alumbat Corporation has $800,000 of debt outstanding, and it pays an interest rate of 10 percent annually on its bank loan. Alumbat’s annual sales are $3,200,000, its average tax rate is 40 percent, and its net profit margin on sales is 6 percent. If the company does not maintain a TIE ratio of at least 4 times, its bank will refuse to renew its loan, and bankruptcy will result. What is Alumbat’s current TIE ratio
