Question

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.
0.0046
0.0056
168.1604
179.0049

Answer 1

Answer:

B.

Step-by-step explanation:

Answer 2

It is given that seismic activity density 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
