The linear equation that is modeled by the table is:
y = 2x + 1
How to write the linear equation?A general linear equation is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through two points (x1, y1) and (x2, y2), then the slope is:
a = (y2 - y1)/(x2 - x1)
Here we can use the first two points on the table (-3, -5) and (-1, -1), we will get the slope:
a = (-1 + 5)/(-1 + 3)
a = 4/2 = 2
Then the line is something like:
y = 2x + b
To find the value of b we can use one of the points (-3, -5), replacing these values we will get:
-5 = 2*-3 + b
-5 = -6 + b
-5 + 6 = b
1 = b
Then the linear equation is:
y = 2x + 1

models the number of people N in a town who have heard a rumor after t days.
To the nearest whole number, how many people will have heard the rumor after 3 days?
people
Step-by-step explanation:
Functions can be represented as equations, and equations can be represented as functions.
The number of people that started the rumor is 10
The function is represented as:
To calculate the number of people that started the rumor, we simply set t to 0.
So, we have:
Evaluate the exponent of e
Express e^0 as 1
Multiply 39 and 1
Add 1 and 39
Divide 400 by 40
When t = 0, N(t) = 10
This means that 10 people started the rumor.
Hence, the number of people that started the rumor is 10

Box plot; because job classification is categorical
Box plot; because job classification is numerical
Bar chart; because job classification is categorical
Bar chart; because job classification is numerical
Answer:
Bar chart; because job classification is categorical.
Step-by-step explanation:
Categorical data: Data that can be divided into groups (categories).
Numerical data: Data that is in the form of numbers (also called "quantitative data").
Therefore, "job classification" is categorical data since the classifications such as employee, manager, senior manager, etc. are categories rather than numbers.
Box plots are used to show distributions of numerical data values.
Bar charts are used to show a comparison of values across different categories of data.
Therefore, a bar chart should be used to represent the data as the data is categorical.

Step-by-step explanation:
Augustus Galoop (from Willie Wonka & The Chocolate Factory) LOVED
chocolate. He loved it SO MUCH, he decided to create his very own chocolate
milk He made 30 gallons (he REALLY loves chocolatel). The mixture had to be
perfect, so he started with a recipe of 10% chocolate syrup and 90% milk It
was too weak, so he tried 30% chocolate & 70% milk That was even too
chocolaty for him. "Maybe, If I try 15% chocolate syrup & 85% milk, it'll be
perfect??" So he did, but he forgot how many gallons of chocolate syrup & milk he'd
used for the first two attempts. He DID remember the percentages, though. How
many gallons of chocolate syrup & milk did he use for his final mixture?
Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.
What is a percentage?
Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) besides the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
Since Augustus used 10% chocolate syrup and 90% milk for the first mixture and 30% chocolate syrup and 70% milk for the second mixture, the total percentage of chocolate syrup he used in the first two mixtures is 10% + 30% = 40%.
Since Augustus made a total of 30 gallons of chocolate milk, he used 30 gallons * 40% =3040.01=12 gallons of chocolate syrup in the first two mixtures.
For the final mixture, Augustus used 15% chocolate syrup and 85% milk. The total percentage of chocolate syrup he used for the final mixture is 15%.
Since Augustus used a total of 12 gallons of chocolate syrup in the first two mixtures, he used an additional 12 gallons * 15% = 1215.01=11.8 gallons of chocolate syrup for the final mixture.
Hence, Augustus used a total of 12 gallons + 1.8 gallons = 12+1.8=13.8 gallons of chocolate syrup in the three mixtures.

The distance between the points (3,5) and a line with the equation 5x-3y+10=0 is 10/√34 units.
Given that,
We have to find the distance between the points (3,5) and a line with the equation 5x-3y+10=0.
We know that,
We have a formula that is
Let (x₁, y₁) be the point and ax + by + c = 0 be the line.
Then the distance between a point and a line will be
d=|ax₁+by₁+c|/√(a²+b²)
Here,
(x₁,y₁)=(3,5)
a=5, b=-3 and c=10
So, substituting
d=|5(3)+(-3)(5)+10|/√(5²+(-3)²)
d=|15-15+10|/√25+9
d=|10|/√34
d=10/√34

What is power?
Power is the ability to influence or control the behaviour of others, and to make decisions that affect the outcome of any given situation. It is a form of force that can be both positive and negative, and can be used in various ways. Power can come from a variety of sources, such as money, status, knowledge, physical strength, and social standing. It is a form of authority that can be used to motivate and inspire others, or to manipulate and coerce them. Power is an important part of many social and political systems, and is essential for effective leadership. It is an essential tool for achieving desired outcomes and can be used for good or for ill. Ultimately, power is a form of influence, and its use depends on the individual wielding it.
In general, if a is a positive real number and n is a positive integer, then a^(n/2) is equal to the square root of a^n. This can be written as:
a^(n/2) = sqrt(a^n) = a^(1/2) * a^(1/2)

The measure of arc PD is 56.
What is a measure of arc?
The central angle that creates the intercepted arc's central angle, or the arc measure, is expressed in degrees. Arc length can be estimated as a percentage of the circle's circumference by multiplying the circle's diameter by the arc length, divided by 360.
Here, we have
Given: DR = 4x +4
PR = 50°
The sum of the measure of arc PR + DR = 180°
50° + 4x +4 = 180°
x = 4
Now we can find the measure of the arc of PD. we put the value of x in 12x+ 8 and we get
12(4) + 8 = 56
Hence, the measure of arc PD is 56.

Given m||n, find the value of x ( x+1) (7x-5)
Answer: If two lines are parallel, it means that they have the same slope. Therefore, to find the value of x in this problem, you need to find the slope of line m and line n, and then set them equal to each other.
The slope of a line can be found using the formula:
slope = (y2 - y1)/(x2 - x1)
In this case, you are given the equation of line m in the form "x + 1", and the equation of line n in the form "7x - 5". To find the slope of each line, you can rewrite these equations in the form y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).
For line m, we have:
y = x + 1
The slope of this line is m = 1.
For line n, we have:
y = 7x - 5
The slope of this line is m = 7.
Since line m and line n are parallel, their slopes must be equal. Therefore, we can set these slopes equal to each other and solve for x:
1 = 7
This equation has no solution, which means that there is no value of x that will make these two lines parallel. Therefore, the answer is that there is no solution.

What is the formula for the Pythagorean theorem?[tex]AC^2 = AB^2 + BC^2[/tex] is the formula for the Pythagorean theorem, where AB is the perpendicular, BC is the base, and AC is the hypotenuse. All triangles with 90° angles are governed by the Pythagorean equation.
The hypotenuse formula can be used to define the relationship between the sides of a right triangle, making it a specific kind -
[tex]c^2 = a^2 + b^2\\or\\c^2 = x^2 + y^2[/tex]
where,
The triangle's hypotenuse, or c, is the side that faces away from the 90-degree angle.
