Alvaro is interested in the relationship between weather conditions and whether the downtown train runs on time. For a year, he records whether each day is sunny, cloudy, rainy, or snowy, as well as whether this train arrives on time or is delayed. Here are his results: Weather conditionOn timeDelayedTotal

Which of the following statements is true?

When the weather was rainy, it was more likely for the train to be delayed than on time.

(Choice B)
B
When the weather was snowy, it was more likely for the train to be delayed than on time.

(Choice C)
C
More than half of the delays occurred on rainy days.

(Choice D)
D
The most delays came on snowy days.

the answer to this problem is b

Step-by-step explanation:

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
