Step-by-step explanation:
added the answe in the sreen shot below that fully explains it
In chapter 1, we introduced several sampling methods: Simple random sample, stratified sampling, systematic sampling, and cluster sampling. All the sampling methods except for convenience sampling, allow for unbiased statistical inference to be made. Convenience sampling typically leads to an unrepresentative sample and biased results. In this week's discussion board, you are asked to design a sample that is representative of the population and unbiased. Scenario: A marketing executive for Coca- Cola, Inc. wants to identify television shows that people in the Seattle area who typically drink Coke are watching. The executive has a list of all households in the Seattle area. Task: You are asked to design a sample to obtain the individuals in the sample. Use the provided scenario to help the Coca-Cola executive identifying the television shows. Design a sample that meets the requirements we discussed in the previous chapter. You need to explain why did you choose this sampling method.
Answers
Answer:
For the coca-cola case, stratified sampling coupled with random sampling will be used.
Step-by-step explanation:
Before going into discussing the scenario, it is evident to discuss the properties of mentioned sampling methods. They are as follows:
Random sampling as the name indicates is purely by randomness. It is a sample in which each element of the population has an equal chance of coming on.
Systematic sampling is easier than random sampling. Here all the elements are arranged in an order and the kth element is considered after a specific interval.
Cluster Sampling is another type of sampling where the population is divided into groups probably on the basis of their geographical location and all the elements of the cluster are then used.
Stratified Sampling is a two-step sampling method where firstly the population is divided into strata, groups on basis of some characteristic, like gender, age, and then another sampling method as the random or systematic method is chosen to pick samples from each of these strata.
On the basis of properties presented and the scenario outlined, it is evident that the population will be divided into strata based on age, gender, profession, and education, and then a random sampling within each stratum is used for all the population of the Seattle area.

Answer:
Step-by-step explanation:
assuming this is set up as it is meant to, we would have 9+(2/8)^3. This can be simplified by reducing (2/8)^3 into 1/64. This leaves 9+1/64, this gives 577/64. Hope this helps!

Henri puts aside $10 cash every month in a shoebox. He also makes a one-time deposit of $1,500 in a savings
account at 9% annual interest, compounded yearly,
Amount of shoebox savings: f(t) = 120t
Amount of savings account: g(t) = 1,500(1.09)^t
Which function represents the amount of money Henri will have after t years?
Answers
Answer:
T(t) = f(t) + g(t)
Step-by-step explanation:
The function which represents the total amount of money Henri will have in t years is the function obtained using an addition operation in the two defied functions, f(t) and g(t) ; total amount saved in shoe box plus the total compounded amount in savings account
Total amount of money in t years, T(t) ;
T(t) = 120t + 1,500(1.09)^t
f(t) = 120t
g(t) = 1,500(1.09)^t
Hence,
T(t) = f(t) + g(t)

Solve for xxx. Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions. 54x+64 \geq 49x + 5954x+64≥49x+59
Answers
Answer:
x ≥-1
Step-by-step explanation:
Given the inequality
54x+64≥49x+59
Collect the like terms
54x - 49x ≥ 59 - 64
5x ≥ -5
Divide both sides by 5
5x/5 ≥ -5/5
x ≥ -1
Hence the required solution is x ≥-1

B)g(x) = f(x + 2) + 4
C)g(x)=f(x-4)-2
D)g(x)=f(x + 4)-2
Answers
Answer:
A
Step-by-step explanation:
g
[tex]g(x) = f(x - 2) + 4[/tex]
A function assigns the value. The equation of the function g(x) will be f(x-2)+4.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given f(x) is a function which is shifted two units to the right and 4 units upwards. Therefore, in the function f(x) we need to add -2 to the value of the x for the function to move right, while we need to add 4 to the overall function to move it four units upwards.
Hence, the equation of the function g(x) will be f(x-2)+4.

substitiution method i really need help
Answers
Answer:
x = 7
y = 0
Step-by-step explanation:
Equation: 2x - 9y = 14
We are given that x = -6y + 7
So we substitute (-6y + 7) for "x" in the equation 2x - 9y = 14
* substitute *
2 ( -6y + 7 ) - 9y = 14
now we solve for y using basic algebra
step 1 distribute the 2
2 * -6y = -12y
2 * 7 = 14
now we have -12y + 14 - 9y = 14
step 2 combine like terms
-12y - 9y = -21y
now we have -21y + 14 = 14
step 3 subtract 14 from each side
14 - 14 cancels out
14 -14 = 0
now we have -21y = 0
step 4 divide each side by -21
-21y / -21 = y
0 / -21 = 0
we're left with y = 0
now to find x
To find x we substitute 0 for "y" in x = -6y + 7
* substitute *
x = -6 ( 0 ) + 7
-6 * 0 = 0
we're left with x = 7

Dieego is making a large mural he draws a hexagon with a perimeter of 10.5 meters each side is the same length. How amny meters long is diegos hexagon
Answers
Answer:
1.75m
Step-by-step explanation:
Given;
Perimeter of the hexagon = 10.5metres
Required
Side length of the hexagon
Since hexagon has 6 equal sides, hence the perimeter is expressed as;
P = 6a
a is the side length of the hexagon
Substitute the perimeter given
10.5 = 6a
a = 10.5/6
a = 1.75metres
Hence the length of each side of the hexagon is 1.75m

En una librería se venden novelas a 16 euros y guías de viaje a 10 euros. Si hoy se han vendido 37 libros en total con una recaudación de 508 euros, calcula el número de ejemplares vendidos de cada tipo.
Answers
Answer:
En la librería se vendieron 23 novelas y 14 guías de viaje.
Step-by-step explanation:
Con la información proporcionada puedes plantear las siguientes ecuaciones:
x+y=37 (1)
16x+10y=508 (2), donde:
x es el número de novelas vendidas
y es el número de guías de viaje vendidas
Primero, puedes despejar x en (1):
x=37-y (3)
Ahora, debes reemplazar (3) en (2) y despejar y:
16(37-y)+10y=508
592-16y+10y=508
592-508=16y-10y
84=6y
y=84/6
y=14
Después, debes reemplazar el valor de y en (3) para encontrar el valor de x:
x=37-14
x=23
De acuerdo a esto, la respuesta es que en la librería se vendieron 23 novelas y 14 guías de viaje.

8 a peice
This means that the money costs 8$ for each of the players. We don't know how many players there are, so we will just label the amount of players as "y"
And we will multiply 8 times y to get our answer
And then we will subtract THAT answer minus 100 to get our full answer.
