Answer:

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is 7739.5.

Step-by-step explanation:

From the given table it is noticed that the electricity generated in Texas by wind powered turbines from 2007 to 2010 are 4353, 7113, 9403 and 10089.

Formula of mean:

[tex]Mean=\frac{\text{Sum of observations}}{\text{Number of observations}}[/tex]

The sum of wind powered turbines from 2007 to 2010 is

[tex]S=4353+7113+9403+10089=30958[/tex]

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is

[tex]Mean=\frac{30958}{4}=7739.5[/tex]

Therefore the mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010 is 7739.5.

Answer:

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010  is  7,739.5 Megawatts.

Step-by-step explanation:

Electricity generated in Texas by wind powered turbines:

In 2007 : 4,353 Mw

In 2008 : 7,113 Mw

In 2009 : 9,403 Mw

In 2010 : 10,089 Mw

[tex]Mean=\frac{\text{sum all observations}}{\text{total number of observations}}[/tex]

[tex]\text{Mean amount of electricity from 2007 to 2010}:[/tex]

[tex]=\frac{4,353+7,113+9,403+10,089}{4}=\frac{30,958}{4}=7,739.5[/tex]

The mean amount of electricity generated in Texas by wind powered turbines from 2007 to 2010  is  7,739.5 Megawatts.
