Let x be the number of material anomalies occurring in a particular region of an aircraft gas-turbine disk. the article "methodology for probabilistic life prediction of multipleanomaly materials" (amer. inst. of aeronautics and astronautics j., 2006: 787793) proposes a poisson distribution for x. suppose that µ = 4. (a) compute both p(x ≤ 4) and p(x < 4). (b) compute p(4 ≤ x ≤ 8). (c) compute p(8 ≤ x). (d) what is the probability that the number of anomalies exceeds its mean value by no more than one standard deviation

Adecibel is a logarithmic unit that can be used to measure the intensity of a sound. the function y = 10logx gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity. the reference intensity is generally set at the threshold of hearing. use the graphing utility to graph the decibel function.a whisper has a sound intensity of 30 decibels. use your graph to you complete the following statement. the sound intensity of a whisper is times the reference intensity.
