What is the shape of the height and weight distribution

The graph shows the decibel measure for sounds depending on how many times as intense they are as the threshold of sound. noise in a quiet room is 500 times as intense as the threshold of sound. what is the decibel measurement for the quiet room? 20 decibels28 decibels200 decibels280 decibels

Which shows one way to determine the facts of x3+4x2+5x+20 by grouping
