(15-16) consider the infinite geometric series:
a) find the partial sums s_n for n = 1, 2, 3, and 4.
b) does the series have a sum?

15  S₁ = 1       S₂ = 4        S₃ = 13        S₄ = 40       Sum = NO            

Step-by-step explanation:

1 + 3 + 9 + 27 + ...    

16              

Step-by-step explanation:

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.

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!
