A vertical angle is two angles formed by intersecting lines, just like the two that form 25 degrees and x degrees. The angles formed by vertical angles are congruent (meaning they are equivalent). So, x=25 degrees.
The process of inferring conclusions about a population from data on selected individuals is called statistical _____.
inferential statistics is the answer.
Statistics is the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data. The two major areas of statistics are descriptive and inferential statistics.
Inferential statistics use measurements from the sample of subjects in the experiment to compare the treatment groups and make generalizations about the larger population of subjects. There are many types of inferential statistics and each is appropriate for a specific research design and sample characteristics.
The most common methodologies in inferential statistics are hypothesis tests, confidence intervals, and regression analysis.

Yes, they are equivalent.
One way you can check this is by substituting any number into x.
For example, x = 2:
• First equation : [tex]\frac{-x}{x + 1}[/tex]
⇒ [tex]\frac{-2}{2 + 1}[/tex]
⇒ [tex]\frac{-2}{3}[/tex]
• Second equation: [tex]\frac{x}{-x-1}[/tex]

Can someone explain 03.05 Polynomial Identities and Proofs for me?
The polynomial Identities and an example of a proof of an identity have been explained below.
What are polynomial Identities and Proofs?Polynomial identities are defined as equations that are always true, regardless of the variable values. These polynomial identities are used while factorizing the polynomial or expanding the polynomial. These polynomial identities are;
(a + b)² = a² + b² + 2ab
(a - b)² = a² + b² - 2ab
(a + b)(a - b) = a² - b²
(x + a)(x + b) = x² + x(a + b)+ ab
Let us prove the polynomial identity (a + b)² = a² + b² + 2ab.
Now, (a + b)² is simply the product of (a + b) and (a + b).
That is; (a + b)² = (a + b) × (a + b)
This can simply be imagined to be a square whose side are (a + b) with its' area equal to (a + b)²

A point is chosen at random on the number line between $0$ and $1$, and the point is colored green. Then, another point is chosen at random on the number line between $0$ and $1$, and this point is colored purple. What is the probability that the number of the purple point is greater than the number of the green point, but less than twice the number of the green point
The probability that the number of the purple point is greater than the number of the green point, but less than twice the number of the green point is 1/4
How to find the Probability?Let the "green" value be an x value lying on segment AC.
Now, the segment AC has the equation y = x. Then, let the "purple" value that is twice a selected x value lie on the segment AE and as such, the equation of this line is y = 2x.
It must be noted that at point E, x = 0.5 and y = 1. This means at every x value on AC greater than 0.5, the value of y on EC associated with this x value is is less than twice that x value.
Then, between segments AE and AC, every value of y will be greater than, but less than twice, its associated x value.
Since triangle ACD has an area of 1/2 and triangle BEA has an area of 1/4, then we can say that;
Triangle AEC area = 1 - (1/2) - (1/4) = 1/4.
Thus, the probability that the number of the purple point is greater than the number of the green point, but less than twice the number of the green point is 1/4

If the length of the hypotenuse of the right triangle whose legs measure 6 feet and 4 square root of 3 feet
The hypotenuse of the right triangle, with legs of 6 and 4√3 feet is 2√21 feet, computed using the Pythagoras Theorem.
The Pythagoras Theorem states that in a right triangle, the square of the hypotenuse is always equal to the sum of the squares of the other two legs.
If the hypotenuse is taken as a, and the two legs are taken as b and c, then by the Pythagoras Theorem, we can write that:
a² = b² + c².
In the question, we are given that a right triangle, has legs of lengths 6 feet and 4√3 feet each, and we are asked to find the length of the hypotenuse.
Thus, taking b = 6 and c = 4√3, in the above equation, we get:
a² = 6² + (4√3)²,
or, a² = 36 + 48,
or, a² = 84,
or, a² = (2√21)²,
or, a = 2√21.
Thus, the hypotenuse of the right triangle, with legs of 6 and 4√3 feet is 2√21 feet, computed using the Pythagoras Theorem.

Total 24
24 and 30 have frequencies of 2 as they appear twice.
From the table, in order to win, a player needs to get 28 or higher.
There are only 8 numbers that are 28 or higher but including the chance that 30 has a relative frequency of 2, we have 9 chances to win the game. The probability is:
= 9 / 24
= 3 / 8
How can a player win 25% of the time?If people are to win only 25% of the time, this means that the number of products that can be picked is:
= 25% x 24
= 6
To find the winning number, count down from the highest product 6 times to get 32.
A person therefore needs to get 32 or above to win 25% of the time.
What is the probability of winning the large price?The probability of getting 36 or higher is:
= Chance of 36 + chance of 40 + chance of 42 + chance of 48
= 1 / 24 + 1/24 + 1/24 + 1/24
= 1 / 6
The probability of repeating this 4 times is:

What is Meant By Graphing Functions?Graphing functions is drawing the curve that represents the function on the coordinate plane. If a curve (graph) represents a function, then every point on the curve satisfies the function equation.
According to the question,
The following graph represents the linear function f(x) = x -2
Take any point on this line, say, (-1, 3).
Let us substitute (-1, 3) = (x, y) (i.e., x = -1 and y = 3) in the function f(x) = -x + 2 (note that it can be written as y = x - 2).
Then
3 = -(-1) + 2
3 = 1 + 2
3 = 3, thus, (-1, 3) satisfies the function.
In the same way, you can try taking different points and checking whether they satisfy the function. Each and every point on the line (in general called "curve") satisfies the function.

Write the standard form of the equation of the line through the pair of points (3,5) and (1,5).
The standard form of the equation of the line passing through the points (3,5) and (1,5) is given by
(Simplify your answer.)
Answer:
y = 5
Step-by-step explanation:
The standard form of a linear equation is Ax + By=C
But let's start with the slope-intercept form: y = mx+b, where m is the slope and b the y-intercept (the value of y when x=0).
M, the slope, may be calculated by using the Rise/Run between the two given points: (1,5) and (3,5):
Rise = (5-5) = 0 [Note that the value of y does not change when x = 1 or 3.]
Run is = (3-1)=2
Rise/Run (slope, m) is (0/2) or 0. [y does not change as a function of x. It is a flat, horizontal line]
The equation becomes y = (2/3)x + b
We need to find a value of b, the y-intercept, that forces the line to go through both points. This can be done by entering one of the points into the equation and solving for b:
y = (0)x + b
I'll use (1,5)
5 = (0)*(1) + b
b = 5
The equation becomes y = (0)x + 5 or y = 5
Standard form of the equation is Ax + By = C
A is 0, B is 1 and C is 5
y = 5
