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 earthquakes per square mile 0.0059 earthquakes per square mile 168.1604 earthquakes per square mile 179.0049 earthquakes per square mile

Answer

Explanation:

Step1: Identify the formula

Seismic activity density = $\frac{\text{Number of earthquakes}}{\text{Land - area}}$

Step2: Substitute the values

Number of earthquakes = 424, Land - area = 71300 square miles. So, density = $\frac{424}{71300}$

Step3: Calculate the result

$\frac{424}{71300}\approx0.0059$

Answer:

0.0059 earthquakes per square mile
