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

Answer 1

Answer:

0.0059 earthquakes per square mile

Step-by-step

The answer is 0.0056 but the closest number to that is 0.0059

Answer 2

Answer:

The correct option is B) 0.0059 earthquakes per square mile.

Step-by-step explanation:

Consider the provided information.

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.

If the there 424 earthquakes and the land area is 71,300 sq miles then find the seismic activity density for this state

This can be calculated by dividing the number of earthquakes with the land area.

Seismic activity density = $\frac{424}{ 71,300}=0.00594670$

Here we need to round it to the nearest ten thousandth.

Thus the nearest ten thousandth is 0.0059

Hence, the correct option is B) 0.0059 earthquakes per square mile.
