Describe four common ways in which individuals respond to perceived inequity are -
People work hard to achieve and maintain equity.If perceive inequity, it causes conflict, which motivates them to reduce or eliminate it.The more severe the degree of inequity, the more motivated people are to decrease or eliminate a certain tension.Unfavorable inequity is more easily perceived than favorable inequity.What is equity?Equity, also known as shareholders' equity (or shareholders' equity for private companies), is the sum of money which would be handed back to a company ’s creditors if each of its assets have been liquidated and all of its debt was paid off in the event of liquidation.
Some key features regarding the equity are-
Equity is the value which would be returned to a company's shareholders if all assets have been liquidated and all debts were paid off.Equity can also be defined as the amount of leftover ownership in an organization or asset remaining after deducting all debts affiliated with that asset.On a company's balance sheet, equity represents the shareholders' stake in the company.Equity is calculated as a firm's revenue assets less total liabilities, and it is included in several important financial ratios like ROE.Home equity is another way to define equity.

Question 4(Multiple Choice Worth 1 points) (01.06 LC) Solve y = x + 4 for x.
Answer:
x = y - 4
Step-by-step explanation:
"Solve for x" means to get the x all by itself on one side of the equation.
We start with:
y = x + 4
Subtract 4 from both sides of the equation.
y - 4 = x
This is the same as
x = y - 4
Now it is "solved for x" because the equation shows what x is equal to.

Which sentence expresses numbers correctly? When the temperaturos fell below Zero degrees Fahrenheit, the employees decided to take public transportation When the temperatures fell below 0 degrees Fahrenheit, the employees decided to take public transportation When the temperatures fell below zero degrees Fahrenheit, the employees decided to take public transportation
The sentence that expresses numbers correctly is: "When the temperatures fell below zero degrees Fahrenheit, the employees decided to take public transportation."
In the sentence, the number is correctly expressed as "zero degrees Fahrenheit." When referring to temperatures below freezing, it is common to use the term "zero" to indicate the absence of heat. The numerical value of zero is represented by the numeral "0," rather than the word "Zero."
Additionally, the unit of measurement, Fahrenheit, is capitalized as it is a proper noun derived from the name of the scientist who developed the temperature scale.
Therefore, the sentence "When the temperatures fell below zero degrees Fahrenheit, the employees decided to take public transportation" accurately conveys the correct numerical and linguistic representation of the temperature.

according to a report for veterinarians in the united states, 36.5 36.5 percent of households in the united states own dogs and 30.4 30.4 percent of households in the united states own cats. if one household in the united states is selected at random, what is the probability that the selected household will own a dog or a cat? responses 0.111 0. 111 0 point 1 1 1 0.331 0. 331 0 point 3 3 1 0.558 0. 558 0 point 5 5 8 0.669 0. 669 0 point 6 6 9 not enough information is given to determine the probability.
The probability that a randomly selected household in the United States owns a dog or a cat is approximately 0.558 or 55.8%.
The probability that a randomly selected household in the United States owns a dog or a cat, we need to calculate the union of the two events, which is the probability that a household owns a dog or a cat or both.
We can use the formula for the union of two events:
P(Dog or Cat) = P(Dog) + P(Cat) - P(Dog and Cat)
Where,
P(Dog) is the probability that a household owns a dog,
P(Cat) is the probability that a household owns a cat and
P(Dog and Cat) is the probability that a household owns both a dog and a cat.
Since the events "owning a dog" and "owning a cat" are not mutually exclusive (a household can own both), we need to subtract the probability of owning both to avoid double counting.
From the report,
We know that P(Dog) = 36.5% = 0.365 and P(Cat) = 30.4% = 0.304. However,
We do not have information on the probability of owning both a dog and a cat.
Assuming that owning a dog and owning a cat are independent events (which may not be a valid assumption in reality), we can estimate P(Dog and Cat) as the product of the individual probabilities:
P(Dog and Cat) ≈ P(Dog) × P(Cat) = 0.365 × 0.304 = 0.11116 (rounded to five decimal places)
Substituting the values in the formula, we get:
P(Dog or Cat) = P(Dog) + P(Cat) - P(Dog and Cat)
= 0.365 + 0.304 - 0.11116 ≈ 0.558

We wish to estimate what percent of adult residents in a certain county are parents. Out of 300 adult residents sampled, 102 had kids. Based on this, construct a 95% confidence interval for the proportion p of adult residents who are parents in this county.
Answer:
The answer is "\(0.34 \pm 0.060\)".
Step-by-step explanation:
Point estimate = Sample proportion \(= \frac{102}{300}= 0.34\)
For \(95\%\) confidence, \(z = 1.96\)
Hence,
Margin of error\(= 1.96 \times \sqrt{0.34\times \frac{0.84}{300}}=1.96 \times 0.0308 = 0.060\)
Therefore,
Confidence interval in the tri-equality form:
\(\to 0.34 - 0.060 < p < 0.34 + 0.060\\\\\to 0.28 < p < 0.4\)
Confidence interval using point estimate and margin of error:
\(p = 0.34 \pm 0.060\)

A clothing manufacturer is examining the efficiency of its factories. All of its factories produce an average of 1,250 pairs of jeans each month, with a standard deviation of 125 pairs of jeans, normally distributed. How many pairs of jeans produced separates the lowest 33% of the means of jean production from the highest 67% in a sampling distribution of 12 factories
Using the normal distribution, it is found that 1234 pairs of jeans produced separates the lowest 33% of the means of jean production from the highest 67% in a sampling distribution of 12 factories.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).For this problem, the parameters are given by:
\(\mu = 1250, \sigma = 125, n = 12, s = \frac{125}{\sqrt{12}} = 36.08\)
The desired amount is the 33rd percentile, which is X when Z = -0.44, hence:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem
\(Z = \frac{X - \mu}{s}\)
-0.44 = (X - 1250)/36.08
X - 1250 = -0.44 x 36.08
X = 1234.
1234 pairs of jeans produced separates the lowest 33% of the means of jean production from the highest 67% in a sampling distribution of 12 factories.

Write the equation of the line in Point-Slope Form given the information below. Slope=-1/5 y-intercept=-3
Answer:
your correct answer is y=-1/5-3
Step-by-step explanation:
The linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)
How to determine the line equation?The slope is given as:
m = -1/5
The y-intercept is given as:
c = -3
A linear equation in slope intercept form is represented as:
y = mx + c
So, we have:
y = -1/5x - 3
The equation in point slope form is calculated as follows:
y = -1/5x - 3
Add 3 to both sides
y + 3 = -1/5x
Express -1/5x as -1/5(x)
y + 3 = -1/5(x)
Subtract 0 from x
y + 3 = -1/5(x - 0)
Hence, the linear equation of the line is y = -1/5x - 3 and y + 3 = -1/5(x - 0)

Provide an appropriate response and show your work. Assume that the random variable X is normally distributed, with mean=90 and standard deviation=12. Compute the probability P(57 < X < 105).
The probability that X is between 57 and 105 is 0.8914.
How to solveGiven:
* X is normally distributed with mean=90 and standard deviation=12
* P(57 < X < 105)
Solution:
* Convert the given values to z-scores:
* z = (X - μ) / σ
* z = (57 - 90) / 12 = -2.50
* z = (105 - 90) / 12 = 1.25
* Use the z-table to find the probability:
* P(Z < -2.50) = 0.0062
* P(Z < 1.25) = 0.8944
* Add the probabilities to find the total probability:
* P(57 < X < 105) = 0.0062 + 0.8944 = 0.8914

A kite is a four sided shape. Like an elongated rectangle.a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite to each other instead of being adjacent. Kite quadrilaterals are named for the wind-blown, flying kites, which often have this shape and which are in turn named for a bird. Kites are also known as deltoids, but the word "deltoid" may also refer to a deltoid curve, an unrelated geometric object.Kites have been used for human flight, military applications, science and meteorology, photography, lifting radio antennas, generating power, aerodynamics experiments, and much more.
