This bar graph shows the number of hurricane in the Atlantic Basin from 2006-2011. Find the amount of change and the percent of

Arada [10]

Answer:

Step-by-step explanation:

Number of hurricanes in year 2008 = 8

Number of hurricanes in year 2009 = 3

Decrease in number of hurricanes = 8 - 3 = 5

Percent of decrease in number of hurricanes = $\frac{5}{8}\times 100$ = 62.5%

Number of hurricanes in year 2010 = 12

Number of hurricanes in year 2011 = 7

Decrease in number of hurricanes = 12 - 7 = 5

Percentage decrease in number of hurricanes = $\frac{5}{12}\times 100$ = 41.7%

Decrease in numbers of hurricanes in year 2010 - 11 was same as in year 2010 - 11.

Percentage decrease in hurricanes were more in year 2008 - 09 than percentage decrease in year 2010 - 11.
