The scientific discipline that examines the mind and behaviour is known as psychology. The study of thoughts, emotions, and other conscious and unconscious events is included in psychology. The social and natural sciences are linked by this highly interdisciplinary area of study. Because psychologists are interested in the emergent features of the brain, psychology and neuroscience are interwoven.

here, we have,

we know that,

A psychologist is a researcher with a focus on psychology or a recognized authority in the field. On perception, cognition, attention, emotion, intelligence, subjective experiences, motivation, brain function, and personality, psychologists do research. Interpersonal relationships, psychological resiliency, family resiliency, and other topics relating to social psychology are topics that psychologists are interested in. Research psychologists employ empirical methods to identify correlational and causal links between various psychosocial variables.

Answer:

t=1/2

Step-by-step explanation:

Based on the direct variation relationship between x and y, where y is 33 when x is 11, we find that y is 36 when x is 12.

If x and y vary directly, it means that they have a constant ratio between them. We can express this relationship as:

y = kx,

where k is the constant of variation.

To find the value of k, we can use the given information that when x is 11, y is 33. Substituting these values into the equation, we have:

33 = k * 11.

Dividing both sides by 11, we find:

k = 3.

Now that we have determined the constant of variation, we can find y when x is 12 by substituting this value into the equation:

y = 3 * 12.

Evaluating this expression, we get:

y = 36.

Therefore, when x is 12, y will be 36.

Based on the direct variation relationship between x and y, where y is 33 when x is 11, we find that y is 36 when x is 12.

The approximate probability P that the total weight of the passengers exceeds 4500 pounds is 10.03%.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes

Total of 22 is more than 4500 is equivalent to average of 22 is more than \($\frac{4500}{22}\)=204.545

\($$\begin{aligned}P(\bar{x} > 204.545) & =1-P(\bar{x} < 204.545) \\& =1-P\left(\frac{\bar{x}-\mu}{\sigma / \sqrt{u}} < \frac{204.545-195}{35 / \sqrt{22}}\right) \\& =1-P(z < 1.2792) \\\end{aligned}$$\)

                        = 1 - 0.8997

                        = 0.1003

Answer:

A worked 20 hours and B worked 15 hours.

Step-by-step explanation:

Given:

Mechanic A hourly rate = $55

Mechanic B hourly rate = $45

Total charged = $1775

Let's assume Mechanic A worked 'A' amount of hours and Mechanic B worked 'B' amount of hours, then

Step 1:

First equation: A + B = 35

Second equation: 55xA + 45xB = 1775

Step 2:

First equation can be written as: A = 35 - B

Step 3: Replace value of A in second equation

Second equation: 55x(35-B) + 45B = 1775

                            : 1925 - 55B + 45B = 1775

                            : (1925 - 1775 )/10 = B

                            : B = 15 hours

A worked = 35 - 15

                = 20 hours

Answer:

3/1 cups

Step-by-step explanation:

For this problem, you are finding the equivalent ratio of 3/1. To find the equivalent ratio of that fraction, you have to multiply (or divide) both quantities  by the same number. (in this case the quantities are 3 and 1)

Basically the same as finding equivalent fractions since ratios are a comparison of two numbers by division (fractions involve dividing)

Therefore, the answer is 3/1 cups. (There are also equivalent ratio calculators online to help as well)

The flux of the given sphere as calculated from the data is, flux= 5πa³/6.

We can use spherical coordinates for this sphere with radius r=ar =a.

The surface can then be described using the parametric equation as

r(θ,Ф)= acosθsinФi + asinθsinФj + acossθk

The partial derivatives of this parametric function with respect to its parameters are,

r ϕ​=acosθcosϕi+asinθcosϕj−asinϕk

r θ=−asinθsinϕi+acosθsinϕj

​

Therefore,

the cross product will be ,

ndσ=a²[cosθsin²ϕi+sinθsin²ϕj+sinϕcosϕk]dϕd

In these coordinates

F = 5zk = 5acosФk

therefore on integrating we get ,

flux= 5πa³/6

Flux is a physics term that refers to the number of electric or magnetic field lines that pass through a surface in a given amount of time. Field lines provide a visual representation of the magnitude and direction of the field being measured.

The inverse is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x) = (x+3)^5

Finding the inverse,

\(f(x) = (x+3)^5\\or,\\y = (x+3)^5\)

We replace x with y and vice versa

so,

\(x = (y+3)^5\)

Solving for y,

the the 5th root,

\(\sqrt[5]{x} = y + 3\\y = \sqrt[5]{x} - 3\)

hence the inverse function is,

\(f^{-1}(x) = \sqrt[5]{x} - 3\)

Step-by-step explanation:

f(x)=(x+3)×5

Y=5X+15

The statement that involves descriptive statistics is -

Option A) The Alcohol, Tobacco, and Firearms Department reported that Houston had 1,791 registered gun dealers in 1997.

What are two categories of field statistics?

There are two categories of field statistics. Descriptive and inferential statistics. Both of them help analysts to make sense of row after row data.

Descriptive statistics presents quantifiable descriptions in a simple way. Inferential statistics is used to draw conclusions that go beyond the raw data only. It is used in making judgments, inferences to deeper general conditions.

The Alcohol, Tobacco, and Firearms Department reported that Houston had 1,791 registered gun dealers in 1997.

Descriptive statistics are useful in describing the basic features of the data being analyzed. They simply provide what the raw data shows. They simplify huge amounts of data sensibly and make it presentable in a manageable form.

With regard to the question, raw data is available stating that the registered gun dealers were 1791 in 1997. It, therefore, involves descriptive statistics.

After these reflections, the coordinates of P′ will be ( __4__ , __-4__ ).

What are coordinates?

Coordinates are a pair of numbers that identify a specific point on a coordinate plane, which is a grid of integers. Any point's location on a plane can be described by an ordered pair of values (x, y), which are referred to as coordinates.

Step by step Explaination:

* Let's update a few changes.

If x-axis reflection at position (x, y)

∴ Seeing it is (x , -y)

If the y-axis at position (x, y) was reflected

∴ Seeing it is (-x , y)

* Let's deal with the issue.

The triangle PQR, which is defined by the points P(-4, -4), Q(-1, -3), and R. (-3, -1)

Across the x-axis, the triangle is reflected.

PQR is visible along the x-axis.

All y-coordinates of the vertices P, Q, and R have their signs reversed.

∴ The new points are going to be (-4, 4), (-1, 3), and (-3 , 1)

A reflection of the new vertices along the y-axis will occur.

All of the new vertices' x-coordinates had their signs reversed.

The new points are (4, 4), (1, 3), and (3 , 1).

The updated vertex positions will reflect along the x-axis to produce the letters P'Q'R.

∴ The new vertices' y-coordinates all had their signs flipped.

∴ P' = (4 , -4) , Q' = (1 , -3) , R' = (3 , -1) (3 , -1)

The coordinates of P′ following these reflections will be (4 , -4).

Answer:

\(y=-\frac{4}{5}x-\frac{21}{5}\)

Step-by-step explanation:

The fastest way is to use point-slope form with \(m=-\frac{4}{5}\) and \((x_1,y_1)=(-4,-1)\):

\(y-y_1=m(x-x_1)\\y-(-1)=-\frac{4}{5}(x-(-4))\\y+1=-\frac{4}{5}(x+4)\\y+1=-\frac{4}{5}x-\frac{16}{5}\\y=-\frac{4}{5}x-\frac{21}{5}\)

To graph the line passing through (-4,-1) with slope m = -4/5, we can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where m is the slope and b is the y-intercept.

Substituting m = -4/5, x = -4, and y = -1, we can solve for b:

-1 = (-4/5)(-4) + b

-1 = 3.2 + b

b = -4.2

Therefore, the equation of the line is:

y = (-4/5)x - 4.2

To graph the line, we can plot the given point (-4,-1) and then use the slope to find additional points. Since the slope is negative, the line will slope downwards from left to right. We can find the y-intercept by setting x = 0 in the equation:

y = (-4/5)x - 4.2

y = (-4/5)(0) - 4.2

y = -4.2

So the y-intercept is (0,-4.2).

Using this point and the given point (-4,-1), we can draw a straight line passing through both points.
