The seismic activity density of a region is the ratio of the number of earthquakes during a given time span to the land area aff
ected. A state had 424 earthquakes over a given time span and a land area of 71,300 square miles. What is the seismic activity density for this state? Round to the nearest ten thousandth, if necessary. 0.0046 0.0056 168.1604 179.0049
It is given that seismic activity d<span>ensity of a region is the ratio of the number of earthquakes during a given time span to the land area affected. so if the there 424 earthquakes and the land area is 71,300 sq miles.
seismic activity density = 424 / 71,300 </span> <span>seismic activity density = 0.0059 the closest answer in the choices is 0.0056</span>
The answer is <span>a=<span><span><span>√<span><span>x3</span><span>y5</span></span></span><span> or </span></span>a</span></span>=<span>−<span>√<span><span>x3</span><span>y<span>5</span></span></span></span></span>
