Lot und is measured in decio and the humber IS 10 times the logarithm of the relative intensity: Decibels = 10 log(relative intensity) (a) In this part assume that four stereo speakers, each producing 37 decibels, are placed side by side, multiplying by a factor of 4 the relative intensity of sound produced by only one of the speakers. What is the decibel level of the four speakers together? (Round your ansvwer to the nearest whale number.) | decibels (b) Find an exponential formula giving relative intensity I as a function of decibel level D. I = (c) What is the growth factor for relative intensity as an exponential function of decibels? Reminder: aE = (a . (Round your answer to two decimal places.)

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
