Explanation Golden ratio is defined as, when any length is divided into two parts then “Ratio of shorter path to longer path is equal to ratio of longer part to whole length. Golden ratio is identified by the Greek letter “phi ( φ ) ” and is approximately equal to 1.618 … . The diagrammatic representation of golden ratio is shown in Figure 1. From Figure 1, golden ratio can be written as follows. a + b a = a b = 1.618 … = φ Represent the golden rectangle in terms of a and b as shown in Figure 2. Modify Figure 2 for 3 2 ″ HDTV as shown in Figure 3. Find the ratio for 3 2 ″ HDTV. a b = 27. 5 ″ 15. 5 ″ = 1.77 4 ″ Modify Figure 2 for Legal size paper as shown in Figure 4. Find the ratio for Legal size paper. a b = 1 4 ″ 8. 5 ″ = 1

Problem 1: The mean hourly pay of an American Airlines flight attendant is normally distributed with a mean of 40 per hour and a standard deviation of 3.00 per hour. What is the probability that the hourly pay of a randomly selected flight attendant is: Between the mean and $45 per hour? More than $45 per hour? Less than $32 per hour? Problem 2: The mean of a normal probability distribution is 400 pounds. The standard deviation is 10 pounds. What is the area between 415 pounds and the mean of 400 pounds? What is the area between the mean and 395 pounds? What is the probability of randomly selecting a value less than 395 pounds? Problem 3: In New York State, the mean salary for high school teachers in 2022 was 81,410 with a standard deviation of 9,500. Only Alaska’s mean salary was higher.
