The bar graph shows the number of hurricanes in the atlantic basin from 2006 - 2011. between which two years was the percent change the greatest? what was the percent of change during the period.

Step-by-step explanation:

The greatest percentage change refers to which two years presents the biggest difference.

So, to answer the question of the problem, we observe that 2009 is the least year and 2010 (the consecutive year) is the greatest year, this means that they proportion has the biggest difference.

Now, we have to find the percentage for each year, which is calculated dividing the number of hurricanes of the year by the total number of hurricanes of all years together.

From the graph, we observe that the total hurricanes from 2006 to 2011 is

Now, the percentage of the year 2009 is

The percentage of the year 2010 is

So, from 2009 to 2010, the percentage of hurricanes increased

This means that between 2009 and 2010 hurricanes increased a 428%, which is nuts.

the answer is 99.
