A random sample (Sample 1) from grades 9 and 10 showed scores of: 72, 89, 67, 81, 75, 79, 81, 80, 62, 64, 83.
A random sample (Sample 2) of grades 11 and 12 showed scores of: 84, 86, 87, 84, 86, 89, 90, 87, 87, 84, 86.

What is the median of Sample 1?

What is the median of Sample 2?

1.8 or

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}

i would pic false cause it goes down towards negative
