Triangle properties include triangle inequality, angle sum, congruence, exterior angle theorem, and isosceles triangle theorem.

1. Triangle Inequality: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

2. Angle Sum of a Triangle: The sum of the angles of a triangle is always equal to 180°.

3. Congruence of Triangles: If two triangles have all three sides equal, then they are congruent (the same size and shape).

4. Exterior Angle Theorem: The measure of an exterior angle of a triangle is equal to the sum of the measures of the two interior angles that are not adjacent to it.

5. Isosceles Triangle Theorem: If two sides of a triangle are equal in length, then the angles opposite those sides are also equal in measure.

An angle is a shape formed by two lines or rays, which start at the same point and extend in different directions.

Angles are measured in degrees, with a full circle being 360°. Depending on their size, angles can be classified as acute (less than 90°), right (90°), obtuse (more than 90° but less than 180°) and reflex (more than 180°).

Angles are important to mathematics because they can be used to measure distances and calculations between objects. They can also be used to calculate the area of a triangle, a quadrilateral or any other closed form. Angles are also an important part of trigonometry and can be used to help solve problems involving triangles.

The equation of the line in slope intercept form that is perpendicular to y=-5x+3 and passes through (2-0) is  y = 1 / 5x - 2  / 5.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Hence, the line is perpendicular to y = -5x + 3  and passes through (2, 0).

Therefore, perpendicular lines have slopes that are negative reciprocals of one another.

Hence, the slope of the line is 1 / 5.

Let's find the y-intercept using (2, 0).

y = 1  /5 x + b

0 = 1  /5(2) + b

b = - 2  /5

What is a line of best fit?

The straight line that best depicts the overall picture of what the collected data is showing is known as the line of best fit, also known as a trendline or a linear regression. It aids in determining whether the two things under study are related or have a correlation. This trendline aids in our ability to forecast upcoming developments involving the data under study.

The line models a positive association is incorrect, because the plot has a negative slope which means that it has a negative association.

The data does not have a linear association is wrong because it can seen that the plot does show that most of the points are clustered around a path that would be a line through the points.

It is not necessary for a line of best fit to go through any of the original points so line does not pass through any of the data points is also incorrect.

Step-by-step explanation:

The two functions are inverse of one another using the composition function.

It is suggested that we replace one function with another using the composition operator. The result will be reversed if two functions are inverses of one another.

According to the composition function if f(g(x)) = g(f(x)) = x; then f(x) and g(x) are inverse of one another.

The composition of f(g(x)) is given as follows:

Substitute  [tex]x= g(x) = \frac{x-2}{5}[/tex] in f(x):

[tex]f(g(x)) = 5 (\frac{x-2}{5}) + 2[/tex]

[tex]f(g(x)) = x -2 +2[/tex]

[tex]f(g(x)) = x[/tex]

The composition of g(f(x)) is given as follows:

Substitute x= f(x) = 5x + 2 in g(x):

[tex]g(f(x)) = \frac{5x+2 -2}{5}[/tex]

[tex]g(f(x)) = \frac{5x}{5}[/tex]

[tex]g(f(x)) = x[/tex]

A tangent line is a line that intersects a curve at a single point, with the same slope as the curve at that point. A secant line is a straight line that intersects a curve at two or more points.

A line that touches a curve only at one point is called a tangent line, while a line that passes through two points on a curve is called a secant line. A secant line has a slope that is the average of the slopes of the two points it passes through, whereas a tangent line has a slope that is the same as the slope of the curve at the point of tangency.

A secant line can be used to approximate the rate of change of a curve over a range of values, whereas a tangent line can be used to determine the instantaneous rate of change of a curve at a given point.

The probability that a randomly chosen test taker had a score greater than 1,127 is 0.1587.

For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.

First, solve for the z-score using the formula below

z-score = (x – μ) / σ

where x = individual data value = 1,127

μ = mean = 896

σ = standard deviation = 231

z-score = (1,127 - 896) / 231

z-score = (231) / 231

z-score = 1

Find the probability that corresponds to the z-score in the z-table. (see attached images)

at z = 1,     p = 0.8413

Since the probability we have calculated is for the scores less than and including 1,127, subtract the calculated probability from 1.

probability = 1 - 0.8413 = 0.1587

Hence, the probability that a randomly chosen test taker had a score greater than 1,127 is 0.1587.

To prepare 22 pancakes Kai needs a total of 3 cups of pancake mix, which means the ratio is 22 to 3 or 22:3.

To find the total of pancake mix Kai need for this new number of pancakes different methods can be applied:

First method: Rule of three

3 cups of pancake mix = 22 pancakes

Based on the relative proportion of your position to the first person and last person in line, the total length of the line is 204 feet.

The proportion refers to the ratio or quotient obtained by applying the division operation.

The ratio is the relative size or value of a number to another.

Like ratios, proportions are expressed in decimals, fractions, or percentages.

To obtain the needed value, the proportional size of the distance is equated to the distance of the first person in line.

Distance from the first person in line = 102 feet

102 feet = 0.5 (1/2 or 50%) of the total length of the line
