The seismic activity density of a region is the ratio of the number of earthquakes during a given time span to the land area affected. 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.

Denise Beltran · Answer 1

actually the answer is 0.0059

0.0056 is not one of the choices. have a good day

Edward Sullivan · Answer 2

It is given that seismic activity d 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

seismic activity density = 0.0059

the closest answer in the choices is 0.0056
