Can you please provide me with the steps that led to the solution? 1. At the local hockey arena, the food and beverage department need to makepredictions about the revenue for this season. A random sample of 25 fans istaken during the first game, with an average spent per fan to be $35, with thesample standard deviation of $15. The food and beverage department wants90% confidence that the population mean will be between what two values?

A railway line connects Parnac station with Rougelle station. The distance between these two stations is 150 km. -a train departs from Parnac at 17:10 and stops at Bernouille station at 17:40. Bernern is 60 km from Parnac - He leaves Bernouille twenty minutes later and crosses the Sévillon train station at 18:30. The Sévillon train station is 45 km from Rougelle. He continued his journey at the same speed until Rougelle station. -Another train leaves Rougelle at 17:35 and arrives at Sévillon at 18h. After 10 minutes of waiting he leaves to reach Bernouille at 18:40 and stops 10 minutes. He finally joined Parnac at 19:20. "At what time and how far from Rougelle do the trains intersect?"
Can you give another solution? This is not very clear
I asked this question earlier but was still very confused on how to solve the problem. If you can please write out step by step and show exactly how to solve this problem it would help give me a more clear visual way on how to solve this. Thank you. QUESTION:
Akira is running around a circular track. Akira runs counterclockwise. From where he starts, it takes him 22 seconds to reach the easternmost point of the track. It takes him 95 seconds to run one complete lap.Bob starts running at the same time as Akira. Bob starts from the northernmost point and runs clockwise. Bob and Akira pass each other for the first time after 26 seconds. How long does Bob take to run one lap of the track? The answer to this question should be the amount of time in seconds rounded to four decimal places that it takes for Bob to run a complete lap around the circular track.
A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race. Preview Solve f(t) = 0 and describe what your solution represents. t = Preview…
I am having trouble understanding the solution. Also the hints do not seem to be used. Some elaboration would be great, thanks!
This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. A person's lean body weight L is the amount he or she would weigh if all body fat were magically to disappear. One text gives the "equation that practitioners can use most feasibly in the field to predict lean body weight in young adult males." The equation is found below. L = 98.42 + 1.08W − 4.14A Here L is lean body weight in pounds, W is weight in pounds, and A is abdominal circumference in inches. Find the approximate lean body weight of a young adult male who weighs 181 pounds and has an abdominal circumference of 41 inches. What is the weight of his body fat? What is his body fat percent?
