In an experiment studying the effects of alcohol on social anxiety, alcohol is the ______ variable. A.) independent. B.) confounding. C.) random. D.) dependent.
In an experiment studying the effects of alcohol on social anxiety, alcohol is the dependent variable. So, correct option is option D.
What is Dependent variable ?Variables: The goal of all research is to describe and explain global dispersion. Variance is just the difference. That is, the fluctuations that occur naturally in the world, or the changes that occur as a result of manipulation. A variable is the name given to the variance you want to describe. A variable is the result of a force or is itself a force that changes another variable. There are two types of variables.
DependentIndependentWhen researchers administer an active drug to one group of people and placebo or an inactive drug to another group of people, the independent variable is drug treatment. Each person's response to active drug or placebo is called the dependent variable.
In this case, an experiment examining the effects of alcohol on social anxiety. Alcohol is the dependent variable here.

A company has found that the demand for its product varies inversely as the price of the product. When the price x is 4.75 dollars, the
demand y is 500 units.
Find a mathematical model that gives the demand y in terms of the price x in dollars.
With the help of algebra mathematical model equation for demand of company's product is given by the equation d = 1800 / p.
What is algebra?
The area of mathematics known as algebra deals with the representation of problems as mathematical expressions. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division.
Let demand for company's product d vary inversely with its price p, which means
d ∝ ( 1/p ) or d = k * ( 1/ p) = k / p ----- 1
As when p = 4.5, d = 400
Putting these in (1), we get 400 = k/ 4.5
Hence #k=400 x 4.5=1800 and our model equation is
d = 1800/p
Hence mathematical model equation for demand of company's product is given by the equation d = 1800 / p.

Find (f - g)(x), if f(x) = 2x2 + 2 and g(x) = 6x2 + 6.
To find (f - g)(x), you can subtract g(x) from f(x):
(f - g)(x) = f(x) - g(x)
= (2x2 + 2) - (6x2 + 6)
= -4x2 + (-4)
= -4(x2 - 1)
Therefore, the result of (f - g)(x) is -4(x2 - 1).

Answer:
100.72 meters
Step-by-step explanation:
To find the total length of the race, we need to sum:
The distance from the starting line to the first hurdle.The distances between the hurdles.The distance from the last hurdle to the finish line.The distance from the starting line to the first hurdle is 13.72 meters.
The distance between each of the 10 hurdles is 8.5 meters.

What are the characteristics of a triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.
In congruent triangles all the sides are equal, with respect to the other triangle.
Calculation:Given that ΔUVW≅ΔTSR.
We can see that in TSR triangle the lengths of TR and TS are given as 50 and 53 now the remaining side RS is 5y-33 as we know that both triangles are similar we compare side RS with side VW
i.e..,
5y-33 = 57
5y = 90
y = 18
So we can now compare vertices vertex V is vertex R , vertex W is vertex S and vertex U is vertex T.
So equating the sides of triangles we get,
12x-7 = 53 and 3z+14 = 50
12x = 60 3z = 36
x= 5 z = 12

where Ï is non real cube root of unity choose the correct answer. abc+bcd+acd+abd is equal to
First, we can rewrite the given equation as:
1/a+Ï + 1/b+Ï + 1/c+Ï = (1/Ï)(1/a + 1/b + 1/c)where Ï is the non real cube root of unity.
We can then multiply both sides of the equation by Ï to get:
1/a + 1/b + 1/c = 2(1/a + 1/b + 1/c)This simplifies to:
1/a + 1/b + 1/c = 0Since a, b, and c are all real numbers, we know that 1/a, 1/b, and 1/c are also real numbers. Therefore, the sum of these three real numbers must also be a real number. The only way that 1/a + 1/b + 1/c can equal 0 is if all three of these terms are equal to 0.
Thus, we can conclude that a = b = c = 0.
Since a, b, and c are all equal to 0, we know that abc + bcd + acd + abd must also equal 0. Therefore, the answer is 0.

Is DEF = ABC? If so, type the reason, if not type no.
Answer:
Yes
Step-by-step explanation:
All you need to do is figure out the missing angles. We know that the three angles in a triangle add up to 180 degrees.
For angle B in ABC, 180-52-39= 89. So angle B = 89 degrees.
For angle D in DEF, 180-39-89= 52. So angle D = 52 degrees.
Then see if the order of the angles match up.
DEF = 52 degrees, 89 degrees, 39 degrees
ABC = 52 degrees, 89 degrees, 39 degrees
The order of the same angles match, so triangle DEF and triangle ABC are equal.
Answer:
Yes, triangle DEF is similar to triangle ABC because their corresponding angles are the same size.
Step-by-step explanation:
Interior angles of a triangle sum to 180°.
⇒ ∠A + ∠B + ∠C = 180°
⇒ 52° + ∠B + 39° = 180°
⇒ ∠B = 89°
⇒ ∠D + ∠E + ∠F = 180°
⇒ ∠D + 89° + 39° = 180°
⇒ ∠D = 52°
Two triangles are similar if their corresponding angles are the same size.
If ΔDEF ~ ΔABC then:
∠D = ∠A∠E = ∠B∠F = ∠CFrom inspection of the given diagram:
∠D = 52° and ∠A = 52° so ∠D = ∠A∠E = 89° and ∠B = 89° so ∠E = ∠B∠F = 39° and ∠C = 39° so ∠F = ∠CTherefore, the triangles are similar because their corresponding angles are the same size.
Consider two securities, a and b. security a and b have a correlation coefficient of 0.65. security a has standard deviation of 12, and security b has standard deviation of 25. calculate the covariance between these two securities.
a. 300
b. 461.54
c. 261.54
d. 195
e. 200
The correct answer is option D. The covariance between securities a and b is 195.
To calculate the covariance between securities a and b, we can use the formula:
covariance = correlation coefficient * standard deviation of security a * standard deviation of security b
Plugging in the given values, we get:
covariance = 0.65 * 12 * 25 = 195
Therefore, the answer is (d) 195.
The covariance between two securities measures the extent to which the two securities tend to move together. A positive covariance indicates that the securities tend to move in the same direction, while a negative covariance indicates that the securities tend to move in opposite directions.

determine the longest wavelength photon (in nm) which can remove an electron from mercury metal if the work function of the metal is 4.475 ev (1 ev
To determine the longest wavelength photon which can remove an electron from mercury metal, we need to use the equation:
wavelength = hc/work function
What are photons?Photons are just light particles. Photons are basic subatomic particles that convey the electromagnetic force (and so much more). The photon is the basic unit of electromagnetic radiation, or the "quantum."
What is wavelength?A waveform signal that is carried in space or down a wire has a wavelength, which is the separation between two identical places (adjacent crests) in the consecutive cycles. This length is often defined in wireless systems in meters (m), centimeters (cm), or millimeters (mm) (mm).
To determine the longest wavelength photon which can remove an electron from mercury metal, you need to use the equation:
wavelength = hc/work function
where h is the Planck constant (6.626 x 10^-34 Js), c is the speed of light (2.998 x 10^8 m/s), and work function is the minimum energy needed to remove an electron from the metal, in this case 4.475 eV.
Plugging these values into the equation gives:
wavelength = (6.626 x 10^-34 Js)(2.998 x 10^8 m/s)/(4.475 x 1.602 x 10^-19 J/eV)
This simplifies to:
wavelength = 404.4 nm
So, the longest wavelength photon which can remove an electron from mercury metal is 404.4 nm.
