Answer:
Step-by-step explanation:
Even though no answer choices are given, the main benefit of this is that by choosing a randomly from a population it allows every single individual to have the same chance of getting chosen and observed. This randomness allows for that sample group to much more accurately represent the entire population that is being observed without having to conduct additional research. Therefore, becoming extremely useful in such studies.
A sample is a group that is taken out of the population to be tested.
A random sampling occurs when subjects are being selected for a study
The benefit of using random sampling is that each subject in the population is equally likely to be selected and the resulting sample is likely representative of the population.
Random sampling allows for unbiased estimates to be created, but at the cost of efficiency within the research process
Some advantages of random sampling shown below,
It has less risk of carrying an error.There is an equal chance of selection.It requires less knowledge to complete the research.Learn more:

Solve 3x + 8 = x + 16
Answer:
x = 4
Step-by-step explanation:
Move all "x"s to one side of the equation:
(3x + 8) - x = (x + 16) - x
2x + 8 = 16
Subtract 8 from both sides so that all the numbers are on one side of the equation:
(2x + 8) - 8 = (16) - 8
2x = 8
Divide both sides of the equation by 2:
x = 4
Find the value of angle G, C and F
Answer:
G is 37
C is 143
F is 37
Step-by-step explanation:
G is 37 because of a rule called complementary angles. They are two angles that equal to 90 degrees! As shown in the angle right next to it, there is a small square that represents 90 degrees, so that means 53 + g would = 90 degrees as well, making g 37.
C is 143 because of a rule called supplementary angles. Supplementary angles are angles on a line that equal to 180 degrees. No matter how many angles are on a straight line, they will all equal to 180. So since I found out g is 37, I just used one of the lines and did 180-37 = 143.
F is 37, and you could find it in two ways. You can use supplementary angles with the angle of c you just found, or you can just use a rule called vertical angles. It is a rule that says any opposite angles from each other are equal. The opposite angle of F would be G. Since G is 37, F would be 37 as well. Definitely look up these terms if I am confusing them for you!! I hope I helped!!

12.6 + 4m = 9.6 + 8m
Answer:
3 = 4m or 0.75 = m
Step-by-step explanation:
12.6 + 4m = 9.6 + 8m
Subtract 4m from both sides of the equation
12.6 = 9.6 + 4m
Subtract 9.6 from both sides of the equation
3 = 4m
Divide by four on both sides of the equation
0.75 = m

Five hundred consumers were surveyed about a new brand of snack food, Crunchicles. Their age groups and preferences are given in the table.
18–24 25–34 35–55 55 and over Total
Liked Crunchicles 39 66 10 86 201
Disliked Crunchicles 27 19 38 95 179
No Preference 24 37 35 24 120
Total 90 122 83 205 500
One consumer from the survey is selected at random. Use reduced fractions for your responses to each of the following questions.
What is the probability that the consumer is 18–24 years of age, given that they dislike Crunchicles?
Answer:
The probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles is 0.151.
Step-by-step explanation:
The age groups and preferences are given as follows:
18 - 24 25 - 34 35 - 55 55 and over Total
Liked Crunchicles 39 66 10 86 201
Disliked Crunchicles 27 19 38 95 179
No Preference 24 37 35 24 120
Total 90 122 83 205 500
One consumer from the survey is selected at random.
Compute the probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles as follows:
[tex]P(18-24|DC)=\frac{P(18-24\cap DC)}{P(DC)}[/tex]
[tex]=\frac{n(18-24\cap DC)}{n(DC)}\\\\=\frac{27}{179}\\\\=0.15084\\\\\approx 0.151[/tex]
Thus, the probability that the consumer is 18 - 24 years of age, given that they dislike Crunchicles is 0.151.
A cab company charges $4 per cab ride, plus an additional $2 per mile driven. Write an equation that shows the relationship between the distance x and the cost y. Write your answer as an equation with y first, followed by an equals sign.
Answer:
y = 2x + 4
Step-by-step explanation:
So, the cab company charges a flat fee of $4 per cab ride, meaning 4 has no variables in the equation. Now, x is the distance, and the cab company charges $2 per mile driven. Per mile driven is a distance unit, so the x goes with the 2. From that, you can get that the cost is equal to 4 dollars plus 2x (2 times the distance in miles). This is y = 2x+4.

There are 2 value's in a game. one of them is Pancake, the other is waffle. Pancakes are worth 1.5x a waffle. I have 10 waffles, how much Pancake value do I have?
Answer:
Approximately 6.67 pancakes.
Step-by-step explanation:
We can write an equation that relates the two items.
Let P represent Pancake and let W represent Waffle.
Pancakes are worth 1.5 times a Waffle. Therefore:
[tex]W=1.5P[/tex]
To find the Pancake value for 10 Waffles, we can substitute 10 for W and solve for P. Therefore:
[tex]\begin{aligned} W&=1.5P \\ 10&=1.5P \\ 6.\overline{6}&=P \end{aligned}[/tex]
Hence, 10 Waffles equates to approximately 6.67 pancakes.
