Activity
rima wants to learn more about the heights of the students at spring valley middle school. the school teaches students in grades 6 through 8.
each subject is taught by a different teacher, so students change classrooms every period. students don't have a class every period, but every
student has a homeroom class. consider five samples from this population, then answer the questions that follow
sample a: survey four random students in each of rima's classes.
sample b: survey two random students from each homeroom class.
sample c: survey three random girls from every third-period class.
sample d: survey every sath person in the student directory.
sample e: survey every third person in the band directory.
part a
is sample a a random sample? why or why not?

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}

283 square feet

step-by-step explanation:

good luck

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
