The managers used a simple random sample. b) The managers use the company e-mail directory to contact every 3030th employee on the list. Choose the correct sampling method below. A. The managers used a cluster sample. B. The managers used a multistage sample. C. The managers used a stratified sample. D. The managers used a systematic sample. E. The managers used a simple random sample. c) The managers split the company into divisions, with each division containing employees that have similar jobs. Within each division, they select a SRS of employees to contact. Choose the correct sampling
Answer:
1. C. The managers used a cluster sample
2. B)The managers used a systematic sample.
3. The managers used a stratified sample.
Step-by-step explanation:
1. In a cluster sampling method, the population would be divided into several small units called cluster by the researcher. Within these clusters we randomly pick one or more to observe.
2. In systematic sampling we select elements from an ordered sampling frame.
3. In stratified sampling, the population is divided into several stratas and the researcher then selects randomly to complete the sampling process

6x + 2 = 5x + 17, would there be one unique solution? What is it?
Answer:
X = 15
Step-by-step explanation:
1.- Rewrite the equation, Put like terms on the same side
6x - 5x = 2 - 17
Instead of adding subtract
2.- Divide 1 on both sides
1x = 15
You should only have X on the left side
3.- You should have
X = 15

Given h(x)=-x-4h(x)=−x−4, solve for xx when h(x)=9h(x)=9.
Answer:
[tex]x=-5[/tex]
Step-by-step explanation:
Given [tex]h(x)=-x-4[/tex], solve for x when [tex]h(x)=9h(x)=9[/tex].
First we need to figure out what number multiplied by 9 is equal to 9. This number is 1. [tex](1*9=9)[/tex]
Therefore, we know that h(x) should be equal to 1 in order for 9 times h(x) to equal 9.
Create an equation where h(x) = 1.
[tex]h(x)=1 \\ (-x-4)=1[/tex]Solve this equation by adding 4 to both sides of the equation.
[tex]-x=5[/tex]Divide both sides of the equation by -1 to isolate x.
[tex]x=-5[/tex]Check your answer by substituting -5 for x back into the equation to make sure h(x) = 1.
[tex]-(-5) - 4 = 1[/tex]If [tex]h(x)=1[/tex], then the statement [tex]9h(x) =9[/tex] is true, verifying our answer for x is correct.

m angle Y = ?
a
54
b
34

Answer:
m<y= 34
Step-by-step explanation...
6x-23=4x+9
2x=32
x=16
m<y+m<z=180
m<y=73+73=180
m<y=34
An isosceles triangle is a two-dimensional figure which has two equal sides and the two angles opposite to the equal sides are equal.
The sum of the three angles is equal to 180 degrees.
The value of angle m∠Y is 34°.
Option B is the correct answer.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Isosceles triangle:
Two sides are equal.
The angles opposite to the equal sides are also equal.
So,
From the figure we have,
6x - 23 = 4x + 9
Add 23 on both sides.
6x - 23 + 23 = 4x + 9 + 23
6x = 4x + 32
Subtract 4x on both sides.
6x - 4x = 4x + 32 - 4x
2x = 32
Divide both sides by 2.
x = 32/2
x = 16
The sum of the three angles of the Isosceles triangle given must be 180 degrees.
6x - 23 + 4x + 9 + m∠Y = 180
Put x = 16
6x16 - 23 + 4x16 + 9 + m∠Y = 180
96 - 23 + 64 + 9 + m∠Y = 180
146 + m∠Y = 180
Subtract 146 on both sides.
m∠Y = 180 - 146
m∠Y = 34
Thus,
The value of angle m∠Y is 34°.
Option B is the correct answer.

Complete Question
Question: In the bronze medal game of the 2014 FIBA Asia Cup... In the bronze medal game of the 2014 FIBA Asia Cup, and with his team down by two points, Philippines guard Paul Dalistan was fouled while attempting a three-pointer at the buzzer. He missed the shot and headed to the line for three foul shots.
1. Watch the video of Dalistan preparing to take his first shot. Before he shoots, what is the probability that Philippines will win the game? Lose the game? Send it into overtime? Dalistan’s free throw percentage is 84.6%
Answer:
a
The probability that Philippines will win the game is [tex]P(A) = 0.6055 [/tex]
b
The probability that Philippines will lose the game is [tex]P(B) = 0.00365[/tex]
c
The probability that the game will be sent to overtime is [tex]P(C) = 0.06 [/tex]
Step-by-step explanation:
From the question we are told that
The probability of Paul Dalistan making a shot is p = 0.846
The probability of Paul Dalistan not making the shot is [tex]q = 1- p = 1- 0.846=0.154[/tex]
Paul Dalistan team was down by two points
This mean that for Paul Dalistan's team to win the game he must make the 3 free throws
So the probability that Philippines will win the game is mathematically represented as
[tex]P(A) = p^3 [/tex]
=> [tex]P(A) = 0.846^3[/tex]
=> [tex]P(A) = 0.6055 [/tex]
Gnerally for Paul Dalistan's team to loss the game it means that Paul Dalistan did not make any of the free shot
Hence the probability that Philippines will loss the game is
[tex]P(B) = q^3[/tex]
=> [tex]P(B) = (0.154 )^3[/tex]
=> [tex]P(B) = 0.00365[/tex]
Generally for the game to be sent to overtime then the game must be tied and for the game to be tied, Paul Dalistan have to make 2 out of the three shots
Hence the probability that game will go to overtime is
[tex]P(C) = 3 * 0.846 * 0.154 * 0.154[/tex]
[tex]P(C) = 0.06 [/tex]
