Write an equation of the line in point-slope form through the pair of points. (9,5) and (8,2)
The general form of a linear equation is y - y1 = m(x - x1) then the point-slope form exists y - 5 = 3(x - 9)
What is point-slope form?The general structure of a linear equation exists y - y1 = m(x - x1). It draws attention to the line's slope and one of the line's points (that exists not the y-intercept).
Given: (x1, y1) = (9, 5) and (x2, y2) = (8, 2)
The point-slope form exists given by,
y - y1 = m(x - x1)
m = (y2 - y1)/(x2 - x1)
substitute the values in the above equation, we get
m = (2 - 5)/(8 - 9)
m = 3
The value of m = 3.
y - 5 = 3(x - 9)
Therefore, the point-slope form exists y - 5 = 3(x - 9).

If it is suggested that people of age, less than or equal to 18 years and of age, greater than or equal to 50 years, should be the first to get a flu vaccine, then we can define a variable "A" to the age group suggested to be prioritized for to vaccinate with the flu vaccine, and the compound inequality to describe the situation can be written as [(A ≤ 18) or (A ≥ 50)].
As per the question statement, it is suggested that people of age, less than or equal to 18 years and of age, greater than or equal to 50 years, should be the first to get a flu vaccine.
We are required to define a variable to the age group suggested to be prioritized for to vaccinate with the flu vaccine, and describe the question mentioned situation in the form of a compound inequality.
To start with, let us first determine the variable. It is as simple as assuming any alphabet, say "A", to be the age group, suggested to be prioritized for to vaccinate with the flu vaccine.
Since, suggested that people of age, less than or equal to 18 years should be amongst the the first to get a flu vaccine, thus "A" must be less than equal to 18, i.e., [tex][A\leq 18][/tex]...(1)
Similarly, suggested that people of age, greater than or equal to 50 years should be amongst the the first to get a flu vaccine, thus "A" must be greater than equal to 50, i.e., [tex][A\geq 50][/tex]...(2)
Now, combining (1) and (2), we get our required compound inequality to be [(A ≤ 18) or (A ≥ 50)].

The newly built single-depth olympic size swimming pool (50m by 25m by 2m) needs to be filled up.

What is the volume of the cuboid?The volume of a cuboid is equal to the product of the length, width, and height of a cuboid.
The volume of a cuboid is length × breadth× height
As it is 3D geometry
The volume will be L×W×H i.e. 50×25×2 = 2500 m³
Since one cubic meter is equal to 264.172052 gallons,
So 2500 m³ = 264.17 × 2500 = 660425 gallons
If the water bill is equivalent to $1 per 1000 gallons

The postulate of equality or inequality that is illustrated is the transitive postulate of equality
How to determine the postulate of equality or inequality that is illustrated?The illustrated expression is given as
If 1/4 + 1/4 = 2/4 and 2/4 = 1/4 then 1/4 + 1/4 = 1/2
In the above expression, we do not have any inequality sign
This means that the expression is an equation i.e. equality
The transitive postulate of equality states that
if a = b and b = c, then a = c
The given equality expression illustrates the transitive postulate of equality
i.e.
If 1/4 + 1/4 = 2/4 and 2/4 = 1/4 then 1/4 + 1/4 = 1/2
if a = b and b = c, then a = c

The least common denominator of 3/4 and 15/16 is 16.
What is Least Common Denominator?When two or more fractions are given, the least common denominator is the smallest number of all common multiples of the denominators. To find the least common denominator, list the multiples of both denominators until you find the smallest multiple shared by both. Because 28 is the first shared multiple of 4 and 7, it must be the least common denominator of these two fractions.So, LCD od 3/4 and 15/16:
3/4 × 4/4 = 12/1615/16 × 1/1 = 15/16Now, the denominator of both the fractions is the same which is 16.

Points that map onto themselves are said to be invariant points. Invariant points can occasionally appear during a rotation.
Do rotations have invariant points?
The axis of rotation is a line of invariant points that defines the rotation of a three-dimensional figure in space. Since rotation does not alter the shape of the figure being rotated, it is referred to as an isometric transformation along with translation and reflection.Points that map onto themselves are said to be invariant points. Invariant points can occasionally appear during a rotation.

Use the digital tracing paper if it helps you with your
thinking?
The polygon P is translated and rotated respectively to obtain polygon Q.
A translation is a geometric transformation when each point in a figure, shape, or space is moved in a specific direction by the same amount. A translation can also be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.
Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.
ABCD and EFGH are polygons P and Q respectively.

The following variable is not one from a binomial setting but the geometric distribution. if the probability anita makes a hit when batting is 0.46, what is the probability that she gets a hit on her 3rd try.
The probability is 1.38.
Probability is the possibility of an event occurring. We can scale the probability of an event between 0 and 1. 0 refers to an improbable event, and one refers to an event with the highest possibility. The type of probability we will use to solve this problem is the geometric distribution.
The geometric distribution is defined as a discrete probability distribution representing the probability of consecutive failures before success in a Bernoulli trial. There could be only two possible outcomes; either True (1) or False (0).
Bernoulli's trial is an experiment in which we have only two possible outcomes, success or failure. In other words, the geometric distribution repeats Bernoulli trials until it succeeds, then stops. So, achieving success is the ultimate goal and is the point that stops Bernoulli's trials from happening further.
Geometric distribution, the class of probability distributions, is based on three key assumptions, and these assumptions are defined as:
The studies conducted are independent. Each event is independent of the other.
Each attempt has only two outcomes: success or failure. If an event has any other possible output other than 0 and 1, it can not be classified as a Bernoulli trial.
The probability of success, indicated by p, is the same for each trial.
After understanding the concepts stated above now, we will move towards the actual statement of the problem. So, a scenario is given to us that tells us that the variable is from a geometric distribution setting, which means that all of the assumptions for geometric distribution will be applied. The given probability that Anita makes is,
Given = 0.46
So, to find the probability that she will get a hit on her 3rd try, we will add one possibility three times,
p = 0.46 + 0.46 + 0.46
p = 1.38
Or we can also do it like this,
p = 0.46 * 3
p = 1.38
Both ways will provide us with the correct answer.

Write an equation in point-slope form for each pair of points. (0,3) and (3,11)
The equation of point slope form of (1,10) and (5,42) is -2.7x + y - 3 = 0.
How to find the point slope form?A straight line is represented using its slope and a point on the line using point slope form. In other words, the point slope form is used to determine the equation of a line whose slope is "m" and passes through the point (x1, y1).
given that
the coordinates points are (0,3) and (3,11)
(x1,y1) = (0,3)
(x2, y2) = (3,11)
The formula of point-slope is
(y - y1) = m(x - x1)
Here,
x1 = 0 and y1 = 3 but we don't know the value of m.
now,find the value of m using the following formula
[tex]m = \frac{(y2 - y1)}{(x2 - x1)}[/tex]
now, substitute the values, we get
[tex]m = \frac{(11 - 3)}{(3 - 0)}[/tex]
[tex]m = \frac{8}{3}[/tex]
m = 2.7
so, the value of m is 2.7.
substitute these values into the point-slope formula
(y - 3) = 2.7(x - 0)
y - 3 = 2.7x - 0
-2.7x + y - 3 = 0
Hence, the equation of point slope form of (1,10) and (5,42) is -2.7x + y - 3 = 0.
