How do you write the equation of the line in point slope slope intercept form and standard form?
The equation of line passing through the points (3,-2) and (-2,3) in
(a) point slope form is y + 2 = -(x - 3) ;
(b) slope intercept form is y = -x + 1 ;
(c) standard form is x + y = 1 .
The Standard Form of equation of line is written as ⇒ " Ax + By = C " .
it is given that the line is passing through the points (3,-2) and (-2,3) ;
So , the slope(m) is = (3+2)/(-2-3) = 5/(-5) = -1 .
(a) the point slope form is (y - y₁) = m(x - x₁) ;
substituting x₁ = 3 and y₁ = -2 ;
we get ;
(y + 2) = (-1)(x - 3)
y + 2 = -(x - 3) .
(b) the slope intercept form is ⇒ y = mx + c ,
-2 = (-1)3 + c ;
-2 = -3 + c ,
c = -2 + 3 ;
c = 1 ; the equation is ⇒ y = -x + 1 .
(c) the standard form is :
arranging the equation y = -x + 1 ,
we get ;
x + y = 1 .
Therefore , the required equations of line are mentioned above .

Which among the options is one of the factors of x2 x6 − 16?
The sum of two or more numbers that results in a third number is called a factor.
The factor of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex] exists 2x + 1.
What is meant by factors?The definition of a factor is a number that divides another number by itself with no remainder. In other words, if multiplying two whole numbers results in a product, the numbers we are multiplying are factors of the product since the product is divisible by them.
What can split a number exactly are factors. So there is no residual after division. Factors are the sums of two or more numbers that produce a third number. Consequently, a factor is a number that divides another.
The use of more variable factors—those whose values do fluctuate with output—occurs as production rises and falls. Workforce, energy, and directly used raw materials are examples of typical variable components.
Let the given equation be [tex]$& x^2+\frac{x}{6}-\frac{1}{6} \\[/tex]
[tex]$& =\frac{6 x^2+x-1}{6} \\[/tex]
simplifying the above equation, we get
[tex]$& =\frac{1}{6}\left(6 x^2+x-1\right)[/tex]
We will factorize the polynomial by splitting its middle term.
[tex]$& \frac{1}{6}\left(6 x^2+x-1\right) \\[/tex]
[tex]$& =\frac{1}{6}\left(6 x^2+3 x-2 x-1\right) \\[/tex]
simplifying the above equation, we get
[tex]$& =\frac{1}{6}(3 x(2 x+1)-1(2 x+1)) \\[/tex]
[tex]$& =\frac{1}{6}(3 x-1)(2 x+1)[/tex]
[tex]$\frac{1}{6^{}}(3 x-1)$[/tex] and (2x + 1) are factors of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex]
Therefore, the correct answer is option B. 2x + 1

Study the following production possibility curve. the number of data points that illustrate the proper allocation of resources is .
The production possibilities using at least two data points.
The production possibility curve (PPC) is a graphical representation of the various combinations of two goods that can be produced with given resources and technology. It is a visual representation of the opportunity cost of production and helps us to understand the trade-offs that an economy has to make in order to maximize its production of goods and services.In order to illustrate the proper allocation of resources, a minimum of two data points are required. The first data point represents the production of both goods at the same level, while the second data point shows the production of one good at its maximum level while the other good is at its minimum level. The two data points represent the two different production possibilities available to the economy, and they demonstrate the trade-off between the two goods.
For example, if we have an economy that can produce two goods, A and B, the PPC can be used to illustrate the different combinations of these two goods that can be produced with a given level of resources. If we assume that the economy can produce 10 units of A and 8 units of B, the first data point would be (10,8). This represents the combination of A and B that can be produced using the same level of resources. The second data point would be (10,0), which represents the maximum production of A and the minimum production of B. This data point demonstrates the trade-off between the two goods, as more of A can be produced if fewer of B are produced.
Overall, the production possibility curve is a useful tool for understanding the trade-offs that an economy has to make in order to maximize its production of goods and services. By illustrating the production possibilities using at least two data points, the proper allocation of resources can be better understood

B, D, E and F are points on a circle, centre O. ABC is a tangent to the circle. ODC is a straight line. BOE is a diameter of the circle. Angle BCD = 48° Find the size of angle DFE.
Answer:
m∠DFE = 69°
Step-by-step explanation:
The tangent of a circle is always perpendicular to the radius.
Therefore, as ABC is the tangent to the circle, and OB is the radius of the circle:
⇒ m∠CBO = 90°
Interior angles of a triangle sum to 180°. Therefore:
⇒ m∠COB + m∠CBO + m∠BCO = 180°
⇒ m∠COB = 180° - m∠CBO - m∠BCO
⇒ m∠COB = 180° - 90° - 48°
⇒ m∠COB = 42°
Angles on a straight line sum to 180°. Therefore:
⇒ m∠DOE + m∠COB = 180°
⇒ m∠DOE = 180° - m∠COB
⇒ m∠DOE = 180° - 42°
⇒ m∠DOE = 138°
The angle at the center is twice the angle at the circumference.
Therefore:
⇒ m∠DOE = 2 × m∠DFE
⇒ m∠DFE = m∠DOE ÷ 2
⇒ m∠DFE = 138° ÷ 2
⇒ m∠DFE = 69°

A discrete random variable may take on only a countable number of distinct values such as 0,1,2,3,4,...
Definition of discrete random variable-Discrete random variables are usually (but not necessarily) counts. If a random variable can take only a finite number of distinct values, then it must be discrete. Examples of discrete random variables include the number of children in a family, the Friday night attendance at a cinema, the number of patients in a doctor's surgery, and the number of defective light bulbs in a box of ten.
Explanation-The probability distribution of a discrete random variable is a list of probabilities associated with each of its possible values. It is also sometimes called the probability function or the probability mass function.
Example:-
The cumulative distribution function for the above probability distribution is calculated as follows:
The probability that is less than or equal to is 0.1,
the probability that is less than or equal to 2 is 0.1+0.3 = 0.4,
the probability that is less than or equal to 3 is 0.1+0.3+0.4 = 0.8, and
the probability that is less than or equal to 4 is 0.1+0.3+0.4+0.2 = 1.
So, finally we can conclude that discrete random variables can only take a finite number of values.

The length of a rectangular deck i 4 time it width, and it perimeter i 20ft , what the deck area?
The area of rectangular deck with length 8 feet and width 2 feet is 16 ft².
What is area of rectangle ?Area can be defined as the amount of space covered by a plane of a particular shape. It is measured in "number" of square units (cm², inch², ft² etc.). In other words, the space occupied around this shape is called the area of the rectangle.
Rectangle perimeter = 2(length + width)Rectangle area = length x widthWe have, a rectangular deck with
length is 4 times its width and perimeter is 20ft.
Let us assume that "l" and "w" be length and width of a rectangular deck.
so, l = 4 w --(1)
Now, perimeter of rectangular deck = 2 ( l+w)
=> 2(l+w) = 20 --(2)
we have to calculate the area of rectangular deck and for this we have to calculate measure of length and width.
plug the value of "l" in equation (2) from (1)
2(l+w) = 20
=> 2(4w + w) = 20
=> 2× 5w = 20
=> w = 20/10 = 2 feet
from equation (1) , l = 4 × 2 = 8 feet
Area of rectangular deck, A = l× w
=> A = 8× 2 = 16 square feet
