A sample of 255 adults is selected. The adults are dassified according to voter registration status ("registered" or "not registered"). They are also classified according to preferred source of current events information ("television", "newspapers","radio", or "internet sites"). The results are given in the contingency
table below.
Television
Newspapers
Radio

Registered

Not registered

What is the relative frequency of adults in the sample who are not registered to vote and prefer to obtain their information through newspapers?
Round your answer to two decimal places.

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}

the answer

b. they are parallel and will never intersect.
