At a dangerous intersection accidents occur at a rate of 2.5 per month, and the time between accidents is exponentially distributed. let t be the random variable for the waiting time from the beginning of observation until the third accident. find e(t) andv(t).

Let w=23 . what is the value of w + 45 ?

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.

If f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x)
