Classify the random variable X as finite, discrete infinite, or continuous, and indicate the values that X can take. Select an electric utility company at random; X = the exact amount of electricity, in gigawatt hours, it supplies in a year. X is a (finite, continuous, discrete infinite) random variable, since X can assume ( any real number, any real nonnegative integer ,any real nonnegative value .)

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.
