the study of hypnosis and its relationship to hysteria was the starting point for
The study of hypnosis and its relationship to hysteria was the starting point for the development of psychoanalysis by Sigmund Freud.
The study of hypnosis and hysteria in the late 19th century by Sigmund Freud and his contemporaries led to the development of psychoanalysis, a form of psychotherapy that emphasizes the role of unconscious thoughts and feelings in shaping behavior. Through his work with patients suffering from hysteria, Freud became interested in the idea that psychological conflicts could be traced back to early childhood experiences, and that these conflicts could be resolved through the exploration of unconscious thoughts and feelings. This eventually led to the development of psychoanalysis as a theory and practice for the treatment of psychological disorders.

A circle centered at the origin has a radius of 12. What is the equation of the circle? us2 95
The equation of the circle centered at the origin with a radius of 12 is x² + y² = 144.
In order to find the equation of a circle centered at the origin with a radius of 12, we need to use the standard form equation of a circle, which is:
(x - h)² + (y - k)² = r²
Where (h,k) represents the center of the circle, and r represents the radius.
In this case, since the circle is centered at the origin, h = 0 and k = 0. Also, since the radius is 12, we can substitute r = 12 in the above equation to get:
x² + y² = 12²
Simplifying further, we get:
x² + y² = 144

What are the tax consequences to Euclid from the following independent events? In your computations, do not round intermediate division. If required, round the per share answer to two decimal places. Round all other answers to the nearest dollar. a. Euclid bought 500 shares of common stock five years ago for $50,000. This year, Euclid receives 20 shares of common stock as a nontaxable stock dividend. As a result of the stock dividend, Euclid's per share basis is $ X. b. Assume instead that Euclid received a nontaxable preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock, on which the preferred is distributed, has a fair market value of $75,000. After the receipt of the stock dividend, the basis of the preferred stock is $ X, and the basis of the common stock is Φ
Euclid receives 20 shares of common stock as a nontaxable stock dividend.The basis of the common stock remains the same as in scenario a, which is $96.15 per share.
To calculate the per share basis, we divide the original purchase cost by the total number of shares (including the dividend shares). In scenario b, Euclid receives a nontaxable preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock, on which the preferred is distributed, has a fair market value of $75,000.
The tax consequences involve determining the new basis of the preferred stock and the common stock after the dividend. a. To find the per share basis of Euclid's common stock after receiving the stock dividend, we divide the original purchase cost by the total number of shares. The original purchase cost was $50,000 for 500 shares, which means the per share basis was $50,000/500 = $100. After receiving 20 additional shares as a dividend, the total number of shares becomes 500 + 20 = 520.
Therefore, the new per share basis is $50,000/520 = $96.15. b. In this scenario, Euclid receives a preferred stock dividend of 20 shares. The preferred stock has a fair market value of $5,000, and the common stock has a fair market value of $75,000. To determine the new basis of the preferred stock, we consider its fair market value.
Since the preferred stock dividend is nontaxable, its basis is equal to the fair market value, which is $5,000.

You need a piece of paper to measure 64 Dash 25 cylinders if you take two together that each measure 38.4 silver meters how much do you need to cut off
Answer:
The length needed to cut off is 12.55 cm
Step-by-step explanation:
The corrected question is:
you need a piece of paper to measure 64.25 cm. If you tape two together that each measure 38.4 cm, how much do you need to cut off?
Solution:
measurement/length of each paper piece = 38.4 cm
measurement/ length required = 64.25 cm
If length of one paper piece is 38.4 cm then if we tape 2 pieces together then the measurement or length is calculated as:
38.4 + 38.4 = 76.8 cm
So to calculate how much we need to cut off:
length required to cutoff = total length of two pieces - length required
= 76.8 - 64.25
= 12.55 cm
So the length required to cut off is 12.55 cm

The equation of the line normal to the curve y = square root(3x² + 2x) at point (2,4) is given as follows:
y - 4 = -4/7(x - 2).
How to obtain the equation of the line normal to the curve?The equation of the line normal to a curve follows the point-slope definition of a linear function, given as follows:
y - y' = m(x - x').
The function in this problem is defined as follows:
y = square root(3x² + 2x).
Then the derivative of the function, applying the chain rule, is given as follows:
y' = (6x + 2)/(2 x square root(3x² + 2x))
y' = (3x + 1)/square root(3x² + 2x)
At x = 2, the numeric value of the derivative is of:
y' = 7/square root(16) = 7/4.
The slope of the normal line is calculated as follows:
m x 7/4 = -1
m = -4/7.
(as the normal line is perpendicular to the tangent line, which has slope equals to the numeric value of the derivative at the point).
The coordinates of the point at (2,4), hence:
x' = 2, y' = 4.
Then the definition of the normal line is given as follows:

identify a true statement about contextual interference. multiple choice question. it refers to the harmony between memory and performance. it leads to the variable practice schedule problem. it is high if a practice schedule involves a random arrangement of trials. it is low if a practice schedule organizes each task variation in various blocks of time.
A true statement about contextual interference is: it is high if a practice schedule involves a random arrangement of trials.
Contextual interference is a phenomenon in motor learning where practicing multiple variations of a task in a random or mixed order results in interference or disruption during learning. The interference caused by practicing in a mixed order appears to be counterintuitive, as it creates a challenge for the learner to constantly switch between different task variations. However, this interference has been shown to lead to better long-term retention of the learned skill.
The reason why contextual interference works is related to the way our brains process and consolidate information. When we practice a motor skill in a blocked or consistent order, our brains can quickly and easily memorize the movements required for that skill. However, this type of learning tends to be shallow, and the skill is not retained as well over time. In contrast, when we practice a skill in a random or mixed order, our brains have to work harder to distinguish between the different variations of the task. This additional processing load strengthens the neural connections underlying the skill, leading to more durable and flexible memory representations.

(BXC)| .
The volume of the parallelepiped with sides given by vectors A, B and C is 13 cubic cm, which is the final answer.
The given vectors are:
A = [-4, 3, 2] cm, B = [2,1,3] cm and C= [1, 1, 4] cm
In order to calculate the volume of parallelepiped, we will use vector triple product equation:
Volume = A . (BXC)|, where BXC represents the cross product of vectors B and C.
Step-by-step solution:
We have, A = [-4, 3, 2] cm
B = [2,1,3] cm
C = [1, 1, 4] cm
Now, let's find BXC, using the cross product of vectors B and C.
BXC = | i j k| 2 1 3 1 1 4 | i j k | = -i + 5j - 3k
Where, i, j, and k are the unit vectors along the x, y, and z-axes, respectively.

In a recent poll, 280 people were asked if they liked dogs, and 48% said they did. Find the margin of error of this poll, at the 95% confidence level.
As in the reading, in your calculations:
--Use z = 1.645 for a 90% confidence interval
--Use z = 2 for a 95% confidence interval
--Use z = 2.576 for a 99% confidence interval.
To find the margin of error for the poll at the 95% confidence level, we can use the formula:
Margin of Error = z * sqrt(p * (1 - p) / n)
Given that the sample size is 280 and the proportion of people who liked dogs is 48% (0.48), we need to determine the appropriate value of z for a 95% confidence interval. The value of z for a 95% confidence interval is 2.
Substituting the values into the formula, we have:
Margin of Error = 2 * sqrt(0.48 * (1 - 0.48) / 280)
Calculating this expression, we find:
Margin of Error ≈ 2 * sqrt(0.48 * 0.52 / 280) ≈ 2 * sqrt(0.2496 / 280) ≈ 2 * sqrt(0.000892)
Simplifying further, we get:
Margin of Error ≈ 2 * 0.0299 ≈ 0.0598
Therefore, the margin of error for this poll, at the 95% confidence level, is approximately 0.0598 or 5.98%.
The margin of error represents the maximum expected difference between the estimated proportion in the poll and the true proportion in the entire population. It indicates the level of uncertainty associated with the poll's results and helps determine the range within which the true proportion is likely to fall. In this case, at a 95% confidence level, we can expect the actual proportion of people who like dogs to be within 5.98% of the estimated proportion obtained from the poll.
