This is a condition known as ankylosis, and it describes a situation in which two bones lose their contact with each other.
What is ankylosis?Ankylosis can result from a variety of causes, including trauma, infection, or degenerative joint diseases. In cases of trauma, the articulating surfaces of the bones can be damaged, leading to a complete absence of contact between the two bones. Similarly, if an infection is present, the cartilage and ligaments of the joint can be destroyed, leading to ankylosis.
Finally, in cases of degenerative joint diseases, such as arthritis, the joint's articulating surfaces can be damaged, leading to a complete loss of contact between the two bones.
The symptoms of ankylosis vary depending on the severity of the condition. In mild cases, the patient may experience stiffness, pain, and reduced range of motion in the joint. In more severe cases, the joint may become completely immobile, and the patient may have difficulty walking or performing other activities.

∠P measures 30° more than the measure of its supplement. What is the measure of ∠P in degrees?
Applying the definition o a supplement of an angle, the measure of angle P in degrees is: 105°.
What is the Supplement of an Angle?The supplement of an angle is defined as the angle measure that is added to the angle to give a sum of 180 degrees.
For example, the supplement of angle X is 180 - measure of angle X.
Given the following:
Supplement of angle P = 180 - measure of angle P
Measure of angle P = (180 - measure of angle P) + 30 degrees
Therefore:
(180 - m<P) + [(180 - m<P) + 30] = 180
Open the parentheses:
180 - m<P + 180 - m<P + 30 = 180
Combine like terms:
390 - 2(m<P) = 180
390 - 180 = 2(m<P)
210 = 2(m<P)
210/2 = 2(m<P)/2

chord of a circle is 13.2 cm long and circles radius is 9.4 find the angle subtended by the chord at the centre of the circle
Answer:
To find the angle subtended by a chord at the center of a circle, we can use the formula:
θ = 2 * arcsin (c / 2r)
where θ is the angle subtended by the chord, c is the length of the chord, and r is the radius of the circle.
Step 1: Substitute the given values into the formula
θ = 2 * arcsin (13.2 / (2 * 9.4))
Step 2: Simplify the equation
θ = 2 * arcsin (13.2 / 18.8)
Step 3: Use a calculator or a math table to find the value of arcsin
arcsin (13.2 / 18.8) = 0.636 radians
Step 4: Multiply the value obtained by 2
0.636 * 2 = 1.27 radians
Final Answer: The angle subtended by the chord at the centre of the circle is 1.27 radians or 72.8 degrees

Determine whether the following statement is true or false. If it is​ false, rewrite it as a true statement.The mean is the measure of central tendency most likely to be affected by an outlier.
The statement that the mean is most likely to be affected by an outlier, is True.
Why is the mean affected by outliers ?The mean (average) of a set of data can be significantly affected by outliers, or data points that are much higher or lower than the majority of the data. Outliers can greatly influence the mean, pulling it away from the center of the data and making it less representative of the majority of the data.
This can cause the mean to become skewed and can give a false representation of the typical values in the data set. This is why it's important to consider the presence of outliers when calculating the mean and to use other measures of central tendency, such as the median or mode, to get a better understanding of the distribution of data in a set.

None of the given data set has the same range as that of the box plot.
What is a box and whisker plot?In descriptive statistics, a box plot or boxplot is a method for graphically demonstrating the locality, spread and skewness groups of numerical data through their quartiles.
In statistics, a quartile is a type of quantile which divides the number of data points into four parts or quarters, of more-or-less equal size.
The data must be ordered from smallest to largest to compute quartiles; as such, quartiles are a form of order statistic.
Q1 → first quartile : Splits off the lowest 25% of data from the highest 75%
Q2 → second quartile : cuts data set in half
Q3 → third quartile : splits off the highest 25% of data from the lowest 75%

Solve the given differential equation by separation of variables.y ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y| =
The solution of the given differential equation is
x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0
The given differential equation can be written as
ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|
To solve this equation, we will use separation of variables. This means that we need to separate the terms containing 'x' and the terms containing 'y' on different sides of the equation.
We can rearrange the equation as,
ln x * (dx/dy) - [(y+1)/x]^2[(y^2)/2] - 2y - ln|y| = 0
Now, let us separate the terms containing 'x' from terms containing 'y':
ln x * (dx/dy) = [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|
On one side of the equation, we have ln x * (dx/dy) and on the other side, we have [(y+1)/x]^2[(y^2)/2] + 2y + ln|y|.
Now, we can integrate both sides of the equation with respect to 'y':
∫ ln x * (dx/dy) dy = ∫ [(y+1)/x]^2[(y^2)/2] + 2y + ln|y| dy
Integrating both sides of the equation, we get
x ln x - (x/2)(y+1)^2 + (y^3)/3 + 2y^2 + y ln|y| + c = 0
where c is a constant of integration.

Why are there 2 answers in an absolute value equation?
An absolute value equation can have two solutions, one for the positive case and one for the negative case. It's important to check both cases to make sure that we have found all of the solutions to the equation.
An absolute value equation is an equation that contains an absolute value function. The absolute value of a number is defined as the distance of that number from zero on the number line. It is always non-negative.
When solving an absolute value equation, we need to consider two cases: the case where the value inside the absolute value sign is positive, and the case where it is negative.
For example, if we have the equation |x| = 2, we can solve it by first considering the case where x is positive:
x = 2 (because the distance from zero is 2 on the positive side of the number line)
Alternatively, we can consider the case where x is negative:
x = -2 (because the distance from zero is 2 on the negative side of the number line)
So in this example, there are two solutions: x = 2 or x = -2.

Answer:
We can set up two equations to represent the information given in the problem:
F = 2S (where F is the father's present age and S is the son's present age)
(F - 10) / (S - 10) = 5/2
We can substitute equation 1 into equation 2:
(2S - 10) / (S - 10) = 5/2
We can cross-multiply and simplify to solve for S:
2S - 10 = 5S - 25
3S = 35
S = 35/3
S = 11.67
So the son is currently 11.67 years old. To find the father's age, we can use equation 1:
F = 2S
F = 2 * 11.67
F = 23.33
So the father is currently 23.33 years old.

what is the area of a triangle if the legs ar5e x and y long. if the first leg of the triangle is x and the length of the second leg is y, the formula
The area of a triangle is Area = sqrt(s(s-x)(s-y)(s-c)).
The area of a triangle can be found using the Heron's formula if we know the lengths of all three sides, or using the formula (1/2) * x * y if we know the lengths of two legs and the triangle is a right triangle.
In the case where the legs of the triangle are x and y long, if we don't know if the triangle is a right triangle, we can't use the formula (1/2) * x * y. However, we can use Heron's formula to calculate the area. Heron's formula states that the area of a triangle is equal to the square root of s(s-a)(s-b)(s-c), where s is the semi-perimeter of the triangle and a, b, and c are the lengths of the three sides.
In this case, since we know the lengths of the two legs x and y, we can find the area of the triangle using Heron's formula as follows:
s = (x + y + c)/2
Area = sqrt(s(s-x)(s-y)(s-c))
Where c is the length of the hypotenuse of the triangle, this information is not provided, so we cannot calculate the area of the triangle.

The range of the function is given by set A = { -11 , -9 , -7 , -5 , -3 }
What are domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

a popular restaurant chain will open a new franchise if a study shows that more than 60% of residents in an area would purchase food from the restaurant. an analyst of a particular area randomly selects 500 residents and surveys them about their interest in the restaurant. of the 500 residents, 320 stated they would purchase food from the restaurant. which hypotheses test the proportion of residents who would purchase food from the restaurant in this area?
The proportion of people in the area who would purchase food from the restaurant is greater than 60%.
Hypothesis testing is used to determine if the proportion of people in a particular area that would purchase food from a particular restaurant is greater than 60%. The null hypothesis, denoted by H0, is that the proportion of people who would purchase food from the restaurant is 60%, or p=0.6. The alternative hypothesis, denoted by H1, is that the proportion of people who would purchase food from the restaurant is greater than 60%, or p>0.6.
To conduct the test, we can use a one-sample proportion test, which is a type of statistical test that compares an observed proportion to a hypothesized proportion. To calculate the test statistic, we can use the formula:
Test statistic = (observed proportion - hypothesized proportion) / (standard error of the proportion)
In this case, the observed proportion is 320/500 = 0.64 and the hypothesized proportion is 0.6. Therefore, the test statistic is:
Test statistic = (0.64 - 0.6) / (square root of (0.6 * (1 - 0.6) / 500))
Test statistic = 0.04 / (square root of (0.6 * 0.4 / 500))
Test statistic = 0.04 / 0.0341
Test statistic = 1.17
The test statistic is 1.17, which is greater than the critical value of 1.645. Therefore, we can reject the null hypothesis and conclude that the proportion of people in the area who would purchase food from the restaurant is greater than 60%.

This leads to the conclusion that x=5 is the answer to the given function problem.
Function: What is it?A link where every x is related to a distinct y variable is called a function. It's noteworthy that when utilizing the similar y and different xs, the inverse is not possible. Except for vertical and horizontal lines, all linear equations can be expressed as functions.
Here,
a function that we've provided
f(x) = 5 - 25x / x
First, the x common factor in the numerator and denominator will be removed, and the resulting fraction will be zero.
5x -25
The common factor, which is 5, will be removed once more, and we will receive 5.
5(x-5)
In this case, we'll compare the expression to zero.
5(x-5) = 0
We shall discover x's value.
x=5
As a result, x=5 is the answer to the function issue that was presented.

Based on a survey of a random sample of 900 adults in the United States, a journalist reports that 60 percent of adults in the United States are in favor of increasing the minimum hourly wage. If the reported percent has a margin of error of 2.7 percentage points, which of the following is closest to the level of confidence
Therefore , as a result, the z-answer table's to the test statistic problem given above determines that the corresponding confidence level for 1.65 is 90%.
Define test statistic.The Z-statistic, that exhibits the typical normal null hypothesis is true, has been the statistical test for something like a Z-test. Let's say you do a two-tailed X y with a 0.05 significance level and get a 2.5 Z-statistic (also known as a Z-value) depending on your data. The p-value for this Z-value is 0.0124.
Here,
Given :
the following characteristics
The ratio of the sample size n = 900 p equals 0.6 * 900 = 540 p = 540/900 p = 0.6 E = 2.7% = 0.027.
The answer to the above problem is:
=> 0.027 = z* 0.6(1-0.6)/900
=> 0.027 = z* (0.24/900)
=>0.027 = z* 0.00163
=>0.027/0.0163 = z
=>z = 1.65
As a result, the z-answer table's to the test statistic problem given above determines that the corresponding confidence level for 1.65 is 90%.

at a party there are only single women and married men with their wives. the probability that a randomly selected woman is single is $\frac{2}{5}$. what fraction of the people in the room are married men?
60% of the people in the room are married men.
We can use the information that the probability of a randomly selected woman being single is 2/5 to find the fraction of people in the room who are married men.
Let's call the fraction of people in the room who are married men x. The fraction of people in the room who are single women is (2/5) and the fraction of people in the room who are married men and their wives is (1-x)
Since there are only single women and married men with their wives at the party, we know that the sum of the fractions of single women and married men and their wives must be 1.
(2/5) + (1-x) = 1
We can solve this equation for x:
x = 1 - (2/5) = 3/5
So the fraction of people in the room who are married men is 3/5 or 0.6
So, 60% of the people in the room are married men.

How do we use the CONVERSE of the Pythagorean Thm. to determine if a triangle is acute, obtuse, or right
The angles in a triangle are less than 90 degrees, the triangle is acute, greater than 90 degrees, the triangle is obtuse, and exactly 90 degrees, the triangle is a right triangle.
What is the converse of the Pythagorean theorem?
The converse of the Pythagorean theorem states that if the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right triangle.
To determine if a triangle is acute, obtuse, or right, we can use the following:
If all the angles in a triangle are less than 90 degrees, the triangle is acute.
If one angle in a triangle is greater than 90 degrees, the triangle is obtuse.
If one angle in a triangle is exactly 90 degrees, the triangle is a right triangle, using the converse of the Pythagorean theorem, c² = a² + b².
Hence, the angles in a triangle are less than 90 degrees, the triangle is acute, greater than 90 degrees, the triangle is obtuse, and exactly 90 degrees, the triangle is a right triangle.
