The dart board below is comprised of three concentric circles below that have radii 2.7. and 10 inches. Find the probability that a randomly thrown dart that hits the board also lands in the shaded region. Express your answer as a percent (ie. 65%).​

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.
