The following table shows the probability distribution for a discrete random variable.
x 13| 16 |17| 21| 23| 25 |26 |31
p(x) 0.07 |0.21| 0.17| 0.25| 0.05| 0.04| 0.13| 0.08
what is the mean of this discrete random variable. that is, what is e(x), the expected value of x?

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.
