What is inequality?In mathematics, an inequality is a non-equal connection that exists between expressions or values. As a result, imbalance relates to inequality. In mathematics, an inequality connects two values that are not equal. Inequality is not the same as equality. When two points are not equal, the not equal sign is commonly used (). Different inequalities, no matter how small or large, are utilized to calculate contrast values. Many simple inequalities can be solved by modifying its two sides until only the variables remain. But a few factors contribute to inequality: Negative values are divided or added on both sides. Trade off the left and right.

Construct a polynomial function of least degree possible using the given information.
Real roots: −1, 1, 3 and (2,
f(2)) = (2, 7)
The polynomial function of least degree possible using the given information is: f(x) = -7/3 (x+1)(x-1)(x-3)
What is polynomial function?
A polynomial function is a type of mathematical function that consists of one or more terms, each of which is a constant multiplied by a variable raised to a non-negative integer power.
To construct a polynomial function of least degree possible using the given information, we need to use the fact that the function has real roots at -1, 1, and 3. This means that the function can be factored as follows:
f(x) = a(x+1)(x-1)(x-3)
where a is a constant coefficient that we need to determine.
Next, we need to use the fact that the function passes through the point (2, 7) to determine the value of a. We substitute x=2 and f(x)=7 into the above equation and solve for a:
7 = a(2+1)(2-1)(2-3)
7 = -3a
a = -7/3
Therefore, the polynomial function of least degree possible using the given information is:
f(x) = -7/3 (x+1)(x-1)(x-3)
Note that this function has real roots at -1, 1, and 3, and passes through the point (2, 7).

The probability that a randomly selected athlete uses a stair climber for,
(a) P(X < 18) = 0.2514
(b) P(22 < X < 31) = 0.4332
(c) P(X > 30) = 0.0918
Let X be the amount of time an athlete uses a stair climber. Then, X ~ N(22, 6^2) represents a normal distribution with mean 22 and standard deviation 6.
(a) To find the probability that a randomly selected athlete uses a stair climber for less than 18 minutes, we need to calculate P(X < 18).
Z-score for 18 minutes = (18 - 22) / 6 = -0.67
Using a standard normal table or calculator, we find that P(Z < -0.67) = 0.2514.
Therefore, P(X < 18) = P(Z < -0.67) = 0.2514.
(b) To find the probability that a randomly selected athlete uses a stair climber for between 22 and 31 minutes, we need to calculate P(22 < X < 31).
Z-score for 22 minutes = (22 - 22) / 6 = 0
Z-score for 31 minutes = (31 - 22) / 6 = 1.5
Using a standard normal table or calculator, we find that P(0 < Z < 1.5) = 0.4332.
Therefore, P(22 < X < 31) = P(0 < Z < 1.5) = 0.4332.
(c) To find the probability that a randomly selected athlete uses a stair climber for more than 30 minutes, we need to calculate P(X > 30).
Z-score for 30 minutes = (30 - 22) / 6 = 1.33
Using a standard normal table or calculator, we find that P(Z > 1.33) = 0.0918.
Therefore, P(X > 30) = P(Z > 1.33) = 0.0918.

A town with a population of 80,250 people has 500 city blocks. Each block is one-tenth mile long by one-tenth mile wide. Find the population density of the town in the people per square mile.
Answer:
First, we need to find the area of one block:
Area of one block = length x width = (1/10) mile x (1/10) mile = 1/100 square mile
Since there are 500 blocks in the town, the total area of the town is:
Total area of town = 500 blocks x (1/100) square mile/block = 5 square miles
To find the population density, we divide the population by the total area:
Population density = population / total area
Population density = 80,250 / 5 = 16,050 people per square mile
Therefore, the population density of the town is 16,050 people per square mile.

Describe Bisector?In geometry, a bisector refers to a line or plane that divides a geometric figure into two equal parts. Specifically, a bisector divides an angle into two equal angles, a line segment into two equal parts, or a plane figure into two equal areas.
There are two types of bisectors:
Angle bisector: A line or ray that divides an angle into two equal angles is called an angle bisector. The point where the bisector intersects the angle is known as the vertex of the angle.
Segment bisector: A line, ray, or line segment that divides a line segment into two equal parts is called a segment bisector. The point where the bisector intersects the line segment is known as the midpoint of the line segment.
We can use the angle bisector theorem to find the value of x. According to the angle bisector theorem, the length of the segment bisecting an angle in a triangle is proportional to the lengths of the two sides adjacent to that angle.
Let's call the point where ST intersects QS point U. Then, by the angle bisector theorem, we have:
QU / QR = SU / SR
Substituting the given values, we get:
QU / 20 = x / 16
Multiplying both sides by 20, we get:
QU = (20x) / 16 = (5x) / 4
Similarly, we have:
SU / QS = TU / TR
Substituting the given values and simplifying, we get:
SU / 12 = x / 20
Multiplying both sides by 12, we get:
SU = (12x) / 20 = (3x) / 5
Now, we can use the fact that QRS is a triangle to find the remaining side length:
QR + RS = QS
20 + 16 = 12 + SU + QU
36 = 12 + (3x/5) + (5x/4)
Multiplying both sides by 20, we get:
720 = 240 + 12x + 25x
720 = 37x + 240
37x = 480
x = 480/37
So the value of x is approximately 12.97 (rounded to the nearest hundredth).

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
Here, we have
Inequality 1: f(4x - 3) ≥ f(2 - x²), Df = (-8 , 4)
The function increases at (-8,4).
So, we have:
4x - 3 ≥ 2 - x²
Rewrite as:
x² + 4x - 2 - 3 ≥ 0
Evaluate the like terms
x² + 4x - 5 ≥ 0
Expand
x² + 5x - x - 5 ≥ 0
Factorize the expression
x(x + 5) - 1(x + 5) ≥ 0
Factor out x + 5
(x - 1)(x + 5) ≥ 0
Solve for x
x ≥ 1 or x ≥ -5
Rewrite as:
-5 ≤ x ≤ 1
Inequality 2: g(3x² - 2x) ≥ g(3x - 2), Dg = all real numbers
g(3x² - 2x) ≥ g(3x - 2)
(3x² - 2x) ≥ (3x - 2)
Evaluate the like terms
3x² - 2x -3x + 2 ≤ 0
3x² - 5x + 2 ≤ 0
3x² - 3x -2x + 2 ≤ 0
3x(x-1) -2(x-1) ≤ 0
Solve for x
x≤1 or x≤2/3
Hence, the values of the inequalities are -5 ≤ x ≤ 1 and 2/3 ≤ x ≤ 1
