Thousands of jokes have been told about marriage and divorce. Exercises 61-68 are based on the following observations:
• "By all means, marry; if you get a good wife, you'll be happy. If you get a bad one, you’ll become a philosopher. "—Socrates
• "My wife and I were happy for 20 years. Then we met." — Rodney Dangerfield
• "Whatever you may look like, marry a man your own age. As your beauty fades, so will his eyesight."—Phyllis Diller
• "Why do Jewish divorces cost so much? Because they're worth it." — Henny Youngman
• "I think men who have a pierced ear are better prepared for marriage. They've experienced pain and bought jewelry." — Rita Rudner
• "For a while we pondered whether to take a vacation or get a divorce. We decided that a trip to Bermuda is over in two weeks, but a divorce is something you always have."— Woody Allen
If Socrates's thoughts about marriage are excluded, in how many ways can the remaining five jokes be ranked from best to worst?

- Use a calculator to find a decimal approximation for the following trigonometric function. cot 226°54' cot 226°54' (Simplify your answer. Type an integer or a decimal. Round to eight decimal places as needed.)arrow_forwardIn preparing for the upcoming holiday season, Fresh Toy Company (FTC) designed a new doll called The Dougie that teaches children how to dance. The fixed cost to produce the doll is $100,000. The variable cost, which includes material, labor, and shipping costs, is $31 per doll. During the holiday selling season, FTC will sell the dolls for $39 each. If FTC overproduces the dolls, the excess dolls will be sold in January through a distributor who has agreed to pay FTC $10 per doll. Demand for new toys during the holiday selling season is extremely uncertain. Forecasts are for expected sales of 60,000 dolls with a standard deviation of 15,000. The normal probability distribution is assumed to be a good description of the demand. FTC has tentatively decided to produce 60,000 units (the same as average demand), but it wants to conduct an analysis regarding this production quantity before finalizing the decision. (a) Determine the equation for computing FTC's profit for given values of the…arrow_forwardFor all integers a and b, (a + b)^4 ≡ a^4 + b^4 (mod 4).arrow_forward
- Find a plane containing the point (3, -3, 1) and the line of intersection of the planes 2x + 3y - 3z = 14 and -3x - y + z = −21. The equation of the plane is:arrow_forwardDetermine whether the lines L₁ : F(t) = (−2, 3, −1)t + (0,2,-3) and L2 : ƒ(s) = (2, −3, 1)s + (−10, 17, -8) intersect. If they do, find the point of intersection. ● They intersect at the point They are skew lines They are parallel or equalarrow_forwardAnswer number 15arrow_forward
