PLEASE HELP ASAP PLEASE An auto-parts store offers a fuel additive that claims to increase a vehicle’s gas mileage. The additive is poured into a vehicle’s gasoline tank after the tank is filled. To measure the claim, the store offers a free bottle of the additive to customers who drive SUV's, who then provide information about their gas mileage on the store website. A customer argues that the type of vehicle could be a confounding variable in this study.
Which statement best describes the effect of the confounding variable?
Because vehicles of different sizes may respond similarly to the additive, it should be easy to conclude whether the additive improves gas mileage.
Because vehicles of different colors may show differences in gas mileage, the additive may improve the gas mileage in some vehicles but not in others.
Because owners of different types of vehicles may choose not to use the additive, those vehicles will not show an improvement in gas mileage.
Because vehicles of different sizes may respond differently to the additive, it may be difficult to conclude whether the additive improves gas mileage for all vehicles.
Answer:
Because vehicles of different sizes may respond differently to the additive, it may be difficult to conclude whether the additive improves gas mileage for all vehicles.
Step-by-step explanation:

Whether the addition increases gas mileage for all vehicles may be difficult to determine.
What is sample space?The sample space S of a random experiment is defined as the set of all possible outcomes of an experiment. In a random experiment, the outcomes, also known as sample points, are mutually exclusive
Because vehicles of different sizes may respond differently to the additive, it may be difficult to conclude whether the additive improves gas mileage for all vehicles.
The type of vehicle is a confounding variable because it is related to both the independent variable (use of the fuel additive) and the dependent variable (gas mileage), and it could potentially influence the results of the study if not controlled for.
This is because the size of the vehicle, a complicating variable, may alter gas economy independently of the addition, making it challenging to assess the additive's actual impact. As a result, the study's findings might be erroneous or misleading.

6. A music video website received 5.000
comments on a new song they released
The next day, the artist performed the song
on television and an additional 1500
comments were made on the website. What
was the percent of increase?
Answer:
30%
Step-by-step explanation:
To be able to calculate the percent of increase between two numbers, you have to divide the increase by the initial number and multiply by 100:
Increase= 1,500
Initial number=5,000
Percent of increase=(1,500/5,000)*100
Percent of increase=0.3*100
Percent of increase=30%
According to this, the answer is that the percent of increase was 30%.

Davis has 15 quarters . Each quarter is 1 3/4 mm thick . If Davis stacked up all 15 quarters on top of each other , how tall would the stack be ?
Answer:
26 1/4
Step-by-step explanation:
1 3/4*15=26 1/4
If Davis has 15 quarters . Each quarter is 1 3/4 mm thick . If Davis stacked up all 15 quarters on top of each other , then 105/4 is the tallness of the stack.
What is Multiplication?multiplication is a method of finding the product of two or more numbers.
Given,
Davis has 15 quarters
Each quarter is [tex]1\frac{3}{4}[/tex] mm thick.
We need to find the height, If Davis stacked up all 15 quarters on top of each other
This can be achieved by adding [tex]1\frac{3}{4}[/tex] for fifteen times or we can use multiplication.
We have to multiply 15 with [tex]1\frac{3}{4}[/tex] .
Firstly [tex]1\frac{3}{4}[/tex] is converted to improper fraction.
[tex]1\frac{3}{4}[/tex] =7/4
Now 7/4×15
=105/4mm
Hence 105/ 4 is the tallness of stack.

5x + 6y = 20 , 8x - 6y = -46
Answer:
5x + 6y = 20_____(1)
8x - 6y = -46_____(2)
Solving simultaneously:
Eqn(1) + Eqn(2)
5x + 8x + 6y + (-6y) = 20 + (-46)
13x = -26
x = -2
substituting this into Eqn (1):
5(-2) + 6y = 20
-10 + 6y = 20
6y = 30
y = 5
hence:
x = -2,y = 5.

A professional volleyball
team won 28 games and
lost 22. What percent of
their games did they lose?
What fraction represents the
number of games they won?
Answer: Lost 44%, Games won: 28/50
Step-by-step explanation:
Percentage = (part / whole) * 100
The total number of games the team played is 28 + 22, which equals 50.
Percentage of losses = (22/50) * 100 = 44%
Fraction of wins = 28/50

Find the median number of vehicles going through the line in a 15-minute period.
A: 27 vehicles B: 25.85 vehicles C: 30 vehicles D: 26 vehicles
Answer:
The correct answer is: Option D: 26 vehicles
Step-by-step explanation:
Median is the middle value of a sorted data set.
The formula for median depends on the number of values in the dataset.
First of all we have to arrange the given data in order
So,
14 19 23 24 24 24 24 26 26 26 26 26 27 27 28 29 30 30 30 34
Counting the values in the dataset
n = 20
As the number of values is even, the formula for median will be
[tex]M = \frac{1}{2}(\frac{n}{2}th\ value+(\frac{n}{2}+1)th\ value)[/tex]
Putting the values
[tex]M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)[/tex]
The 10th value in dataset is 26 and 11th is also 26 so
[tex]M = \frac{1}{2}(26+26)\\M = \frac{1}{2}(52)\\M = 26[/tex]
Hence,
The correct answer is: Option D: 26 vehicles

What is a linear relationship?We know that when we talk about a linear relationship, we mean the kind of relationship that would obey the equation of the straight line and the equation of the straight line would be y = mx + c
We have to look at the representations and see the one that actually fits into the model that have been shown above and when we look at it we can see that the y = 3x - 7.

The best representation of a linear proportional relationship is the table of values
How to determine the best linear proportional relationship?From the question, we have the following parameters that can be used in our computation:
The list of options
As a general rule, the equation of a linear proportional relationship is represented as
y = kx
Where k is the constant of proportion
This means that the given equations are not proportional relationship because they do not have the form y = kx
i.e. y = 3x - 7 and y = 8x + 25 do not have the form y = kx
Also, the equation y = kx implies that the graph passes through the origin
So, the given graph is not
The equation of the table is represented as
y = Y/X * x
So, we have
y = 2/24 * x
This gives
y = x/12
The equation of the table is of the form y = kx
Hence, the solution is the table of values

dult men have heights with a mean of 69.0 inches and a standard deviation of 2.8 inches. Find the z-score of a man 73.4 inches tall. (to 2 decimal places)
Answer:
The z score is 1.57
Step-by-step explanation:
μ = 69.0, σ = 2.8 and x = 73.4
The objective of the problem is to obtain the z-score of a man 73.4 inches tall. The required z score is derived through the following formula "{x - μ / σ}"
z = 73.4 - 69.0 / 2.8
z = 4.4 / 2.8
z = 1.571428571428571
z = 1.57
Thus, the z score is 1.57.
