Two passengers leave the airport at Kansas City, Missouri. One flies to Los Angeles, California, in 3.4 hr and the other flies in the opposite direction to New York City in 2.4 hr. With prevailing westerly winds, the speed of the plane to New York City is 60 mph faster than the speed of the plane to Los Angeles. If the total distance traveled by both planes is 2464 mi, determine the average speed of each plane.

A tortoise and a hare are competing in a 1600-meter race. The arrogant hare decides to let the tortoise have a 510-meter head start. When the start gun is fired the hare begins running at a constant speed of 8 meters per second and the tortoise begins crawling at a constant speed of 5 meters per second. Define a function f to represent the tortoise's distance from the finish line (in meters) in terms of the number of seconds t since the start of the race.

The game of American roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, where each slot has an equal chance of capturing the ball. Gamblers can place bets on red or black. If the ball lands on their color, they double their money. If it lands on another color, they lose their money. Suppose you bet $1 on red.(a) What's the expected value of your winnings?(b) What's the standard deviation of your winnings?

Experian would like to test the hypothesis that the average credit score for an adult in Virginia is different from the average credit score for an adult in North Carolina. A random sample of 40 adults in Virginia had an average credit score of 699 and a random sample of 35 adults in North Carolina had an average credit score of 682. It is believed that the population standard deviation for credit scores is 44 and 41 for Virginia and North Carolina residents, respectively. Experian would like to set α = 0.05. Define Population 1 as Virginia and Population 2 as North Carolina anda. use the critical value approach to test this hypothesis. b. Construct a 95% confidence interval for the difference in population mean and interpret the results.
