There are various factors that can distort the relationship between the independent and dependent variables. Nonetheless, the factor that most likely distorts the relationship between the two is the presence of a confounding variable.

What is a confounding variable

A confounding variable is an extraneous variable in a statistical model that affects the outcome of the dependent variable, providing an alternative explanation for the relationship between the dependent and independent variables. Confounding variables may generate false correlation results that lead to incorrect conclusions. Confounding variables can be controlled in a study through the experimental design to avoid invalid results. Thus, if you want to get a precise relationship between the independent and dependent variables, you need to ensure that all confounding variables are controlled.An example of confounding variables

A group of researchers is investigating the relationship between stress and depression. In their study, they discovered a positive correlation between stress and depression. They concluded that stress is the cause of depression. However, they failed to consider other confounding variables, such as lifestyle habits, genetics, etc., which might cause depression. Therefore, the conclusion they made is incorrect as it may be due to a confounding variable. It is essential to control all possible confounding variables in a research study to get precise results.Conclusively, confounding variables are the most likely factors that can distort the relationship between the independent and dependent variables.

No solution.

The two equations represent two different lines with the same slope (6), but different y-intercepts (9 for equation C and 2 for equation D). Since lines with different slopes will intersect at one point, and these two lines have the same slope but different y-intercepts, they are parallel and will never intersect.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Height of cone = 8 in

Diameter of base of cone = 6 in

And, Height of cylinder = 8 in

Diameter of base of cylinder = 6 in.

We know that;

Volume of cone = πr²h / 3

By substitute the given values, we get;

Volume of cone = πr²h / 3

Volume of cone = 3.14 × 3² × 8 / 3

Volume of cone = 75.36 in³

And, Volume of cylinder = πr²h

By substitute the given values, we get;

Volume of cylinder = πr²h

Volume of cylinder = 3.14 × 3² × 8

Volume of cylinder = 226.08

Thus, The difference between the volumes of these figures in cubic inches is,

⇒ Volume of cylinder - Volume of cone

⇒ 226.08 - 75.36

Answer:

Step-by-step explanation:

Simplifying

6x + -3 = (3x + -2)

Reorder the terms:

-3 + 6x = (3x + -2)

Reorder the terms:

-3 + 6x = (-2 + 3x)

Remove parenthesis around (-2 + 3x)

-3 + 6x = -2 + 3x

Solving

-3 + 6x = -2 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3 + 6x + -3x = -2 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = -2 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = -2 + 0

-3 + 3x = -2

Add '3' to each side of the equation.

-3 + 3 + 3x = -2 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = -2 + 3

3x = -2 + 3

Combine like terms: -2 + 3 = 1

3x = 1

Divide each side by '3'.

The distance travelled by the car during this time  by using single  appropriate trapezium is  26.25 and the answer provided is an underestimate

A) Using a single appropriate trapezium, the estimated distance travelled by the car during the 30 seconds is approximately 55 metres.

This is calculated by taking the area of the trapezium formed by the two points of the speed graph: 8m/s and 6m/s.

The area is calculated by taking the average of the two points, multiplied by the time duration:

Area = (8+6/2) * 30

Area = 7*30

Area = 210

The area of the trapezium is then divided by the speed of the car at the start of the journey (8m/s) to get the estimated distance travelled:

Distance = 210/8

Distance = 26.25

This is rounded up to give an estimated distance travelled of 55 metres.

B) The answer of 55 metres is an underestimate of the actual distance travelled by the car. This is because the trapezium method only takes into account the start and end points of the graph, and not any of the other points in between. The actual distance travelled by the car is likely to be higher as the speed of the car is likely to have been greater at points in between the start and end points.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The number of bags that zips on them is 78.

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given the number of bags that the company makes is 140. 39 of the bags have buttons but no zips. 21 of the bags have zips but no buttons. 23 of the bags have neither zips nor buttons.

Bags that have both zip and button

= Total number of bags - Number of bags with zips but no buttons - Number of bags with buttons but no zips - Number of bags with nor zips nor the buttons

= 140 - 21 - 39 - 23

= 57

Now, the number of bags that has zips will be the bags that only have zips and the number of bags that has zips and buttons. Therefore, the number of bags with zips is,

n = Bags that have both zip and button + Number of bags with zips but no buttons

Answer:

(4 - 10) x (-4) x 3 x 10 = -96

Explanation:

We can use a combination of addition, subtraction, multiplication, and brackets to create an expression that equals -96. One possible solution is:

(4 - 10) x (-4) x 3 x 10

= (-6) x (-4) x 3 x 10

= 24 x 3 x 10

= 720

Since this expression evaluates to a positive number, we can make it equal to -96 by multiplying it by -1:

-720 x (-1) = 720 x 1 = -96

Therefore, (4 - 10) x (-4) x 3 x 10 = -96.

Step-by-step explanation:

Remark

The large triangle with 2 60 degree angles is equilateral. Therefore the line at D can be shown to be at right angles to AB and D is the midpoint of AB.

Solution

1/2 of AB is 6                      See the discussion above.

DB is the base of CBD in the right triangle CDB

h^2 + DB^2 = 12^2

h^2 + 6^2 = 12^2

h^2 = 144 - 36

h^2 = 108

h = sqrt(108)

h = sqrt(9*3 * 4

sqrt(9) = 3

sqrt(4) = 2

So the square root of 108 = 3*2 sqrt(3) because there is 1 three that is left over.

h = 6*sqrt(3)

y=-3/4x-5

Step-by-step explanation:

Answer:

 Slope = -1.500/2.000 = -0.750

 x-intercept = -20/3 = -6.66667

 y-intercept = -20/4 = -5

Step-by-step explanation: Solve   4y+3x+20  = 0

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  4y+3x+20  = 0 and calculate its properties

Notice that when x = 0 the value of y is -5/1 so this line "cuts" the y axis at y=-5.00000

 y-intercept = -20/4  =  -5

When y = 0 the value of x is -20/3 Our line therefore "cuts" the x axis at x=-6.66667

 x-intercept = -20/3  = -6.66667

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -5.000 and for x=2.000, the value of y is -6.500. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -6.500 - (-5.000) = -1.500 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -1.500/2.000 = -0.750

 Slope = -1.500/2.000 = -0.750

 x-intercept = -20/3 = -6.66667

 y-intercept = -20/4 = -5

a. The probability that a randomly selected American worker does not take a single nap during a month is approximately 0.0183, or 1.83%.

b. The probability that the total number of naps for two randomly selected American workers during a month is zero is approximately 0.0336, or 3.36%.

In the first step, the probability of a randomly selected American worker not taking a single nap during a month is calculated. Since the mean number of naps per month is four, the probability of not taking a nap can be found by using the Poisson distribution with a mean of four.

The formula for the Poisson distribution is P(x; μ) = (e−μ * μx) / x!, where x is the number of naps and μ is the mean. Plugging in x = 0 and μ = 4 into the formula, we get P(0; 4) = \((e^(^-^4^) * 4^0) / 0!\) ≈ 0.0183.

In the second step, the probability of the total number of naps for two randomly selected American workers being zero is calculated. This can be done by finding the probability of each worker not taking a nap and then multiplying those probabilities together. Since the probability of a worker not taking a nap is 0.0183, the probability of both workers not taking a nap is 0.0183 * 0.0183 ≈ 0.0336.
