The statement "If ∠ 1 ≅ ∠ 5 , then lines p and q are skew lines" is false because "If ∠ 1 ≅ ∠ 5 , then lines p and q are parallel lines"

Given,

The statement " If ∠ 1 ≅ ∠ 5 , then lines p and q are skew lines"

Here,

Two lines are cut by a transversal.

If ∠ 1 ≅ ∠ 5  we can say that two parallel line cut by transversal and both are corresponding angles

So,  If ∠ 1 ≅ ∠ 5 , then lines p and q are parallel lines

Hence, the statement "If ∠ 1 ≅ ∠ 5 , then lines p and q are skew lines" is false,  because "If ∠ 1 ≅ ∠ 5 , then lines p and q are parallel lines"

Molly's earning increased by 25%

Percentage increase formula is

Increase/ original value × 100

The first step is to calculate the increase by subtracting 120 from 160

160 -120

= 40

Therefore the percentage increase can be calculated as follows

= 40/160 × 100

= 0.25 × 100

= 25

The equation in slope intercept form is y = -4 / 5 x - 8  / 5

The slope intercept equation can be represented as follows:

y = mx + b

where

Therefore, using (-2, 0)(3, -4) let's find the slope

m = -4 - 0 / 3 - (-2)

m = - 4 / 3 + 2

m = - 4 / 5

Hence, the y = mx + b can be defined as follows:

let's find b, the y-intercept using (-2, 0)

y = -4 / 5 x + b

0 = - 4 / 5(-2) + b

0 = 8 / 5 + b

b = - 8 / 5

The postulate of equality or inequality that is illustrated is the transitive postulate of equality

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

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.

The equation of point slope form of (1,10) and (5,42) is -2.7x + y - 3 = 0.

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.

The general form of a linear equation is y - y1 = m(x - x1) then the  point-slope form exists y - 5 = 3(x - 9)

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).

(x₂, y₂) = (7, 3)

The slope-intercept form:

y = mx + b

Where m is the slope and b is the y-intercept.

The formula for slope is,

m = (y₂ – y₁) / (x₂ – x₁)

We have given,

x₂ = 7

y₁ = 3

y₂ = 3

So,

m = (3 – 3) / ( 7-(-1)) = 0/8 = 0

Slope intercept form,

AB = CA This triangle comprises two sides that are congruent. As a result, it is isosceles.

A coordinate system is a method of determining the position of points or other geometric components on a manifold, such as Euclidean space, by using single or more numbers, or coordinates.

Use the Distance Formula to find the lengths of AB ,BC and CA.

AB has endpoints A(–2, –1) and B(–1, 3).

AB = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the values we get:

AB = √((-1 - (-2))² + (3 - (-1))²)

     = √((1)² + (4)²)

     = √(1 + 16)

    = √(17)

BC has endpoints B(–1, 3) and C(2, 0).

BC = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the values we get:

BC = √((2 - (-1))² + (0 - 3)²)

      = √((3)² + (-3)²)

       = √(9 +9)

       = √(18)

CA = has endpoints C(2, 0) and A(–2,–1).

CA = √((x₂ - x₁)² + (y₂ - y₁)²)

Substituting the values we get:

CA = √((-2  - 2)² + (-1 - 0)²)
