Which geometric series diverges?​
marin [14]

Answer:

1) not diverges

2)not diverges

3) diverges

4)not diverges

Step-by-step explanation:

In geometric series, If the |r|<1 then the series is convergent and if |r|>1 then the series is divergent

Where r is the ratio between the consecutive terms of series.

1) 3/5 + 3/10 +3/20 + 3/40 ......

in the above geometric series

r= (3/10) / (3/5)

 = 1/2

 = 0.5

As |r|= 0.5 < 1, so the series will not diverge

2) -10+4-8/5 + 16/25 -......

in the above geometric series

r= (4) / (-10)

 = -2/5

 = -0.4

As |r|= 0.4 < 1, so the series will not diverge

3) ∑ 2/3(-4)^(n-1)

in the above geometric series

r= -4

As |r|= |-4| = 4 > 1, so the series will diverge

4) ∑ (-12)(1/5)^(n-1)

in the above geometric series

r=1/5

 = 0.2

As |r|= 0.2 < 1, so the series will not diverge !

The trifecta at most racetracks consists of selecting the​ first-, second-, and​ third-place finishers in a particular race in t
MAVERICK [17]
Since you have 11 entries, you have 11 possible winners.
For each winner, you have 10 possible second-place finishers.
For each pair first-second place, you have 9 possible 3rd place finishers.

The possibilities are 11×10×9 = 990
Therefore, you have to buy 990 tickets.
