Find the sum of the following infinite geometric series, if it exists. 2 + 6 + 18 + 54 +…and when you answer this question ive seen a lot of people just adding it together and saying thats the answer and that is not how you do it

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

step-by-step explanation:

first, eliminate the parenthesis:

3

x

+

2

−

4

x

second, group like terms:

3

x

−

4

x

+

2

third, combine like terms:

(

3

−

4

)

x

+

2

→

−

1

x

+

2

→

−

step-by-step explanation:

y > 1/3x

y < = -x + 4

hope this : )
