If the points lie on straight line then, the points should be collinear.
How do you know if the 3 points are on the line?We enter the values and check to see whether we receive a true statement, such as "10 Equals 10," to determine whether a point (x, y) is on the graph of a line. The point is not on the line if we obtain a result other than 6 = 4, as it does not meet the equation. Two lines will coincide if they have a same point and have the same slope. To put it another way, if A, B, and C are three points in the XY plane, they will all lie on a line, or three points will be collinear, but only if AB's slope and BC's slope are both equal.

A research study variable that is believed to be related to the study's variable of interest is accurately described by each of the following terms except dependent.
What is a research variable?
Any variable employed in research that has a cause and effect relationship is referred to as a research variable (also known as a study variable) informally. An array of variables, including independent factors, dependent variables, and intervening variables, can be employed in a study, including research/study variables.
Independent and dependent variables are crucial in research since they provide the framework for a study to be carried out. Confounding factors, controlled variables, superfluous variables, and moderator variables are some other sorts of variables that could be used in a research.

neve has 12 full box of jars of slime and 7 lose jars of slime if neve has a total of 187 jars of slime which equation can be used to find the number of jars in each box
Solving a linear equation, we can see that each box has 15 jars.
Which equation can be used to find the number of jars in each box?
We know that Neve has 12 full boxes of jars of slime, and 7 jars of slime, then if each box has N jars, the total number of jars that Neve has is given by the linear equation:
12*N + 7
Now we know that Neve has 187 jars in total, then we can write:
12*N + 7 = 187
We want to find the value of N, which is the number of jars in each box, so we need to solve the linear equation:
12*N + 7 = 187
12*N = 187 - 7
12*N = 180
N = 180/12 = 15
We conclude that there are 15 jars in each full box.

What is an equation?A mathematical statement made up of two gestures joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value for the variable x as x = 7 after solving this equation.So,
The family of planes equation passing through the intersection of the planes x+2y+3z4=0 and 2x+yz+5=0 is:

Inference is referred to as all the data collected in a particular study.
What is inference?Etymologically, the word "infer" means to "carry ahead." Inferences are stages in reasoning that connect premises to logical conclusions. The dichotomy between deduction and induction in inference theory, which dates at least to Aristotle in Europe, is a classic one (300s BCE). Deduction is inference that results in logical conclusions from premises that are known to be true or that are presumed to be true, while the logic of correct inference is investigated. A universal conclusion is inferred by induction from specific evidence. Contradistinguishing abduction from induction, Charles Sanders Peirce is credited with identifying a third sort of inference. Researchers in the domains of logic, argumentation studies, and cognitive psychology traditionally study human inference (i.e., how people draw conclusions); artificial intelligence researchers create automated inference systems to mimic human inference.

What is regression?Regression is a statistical technique used in the fields of finance, investing, and other disciplines that aims to establish the nature and strength of the connection between a single dependent variable (often represented by Y) and a number of independent variables (known as independent variables).
The most popular variation of this method is linear regression, which is also known as simple regression or ordinary least squares (OLS).
Linear regression determines the actual linear relationship between two variables based on a line of best fit. As a result, the slope of a straight line was used to depict linear regression indicating how altering one variable impacts modifying another. In a linear regression connection, the value of one variable when the value of the other is zero is represented by the y-intercept.

Ted's net pay per week after the taxes is $559.09
Net Pay:
Net pay means take-home pay or the amount employees earn after all payroll deductions are subtracted from their gross pay.
Given,
Ted works as a travel guide for a mountain resort, earning $15.72 per hour. Ted is paid weekly, and works 40 hours in one week. His current federal withholding per week is $69. He works in a state with a flat-rate income tax of 4.63%. He will receive a raise of 5% of his hourly rate.
Here we need to find the Ted's net pay per paycheck, after taxes, if his new federal withholding per week is $75.
Through the given details we know that,
Per hour pay = $15.72
Total work per week = 40
So, the total amount for a week is
=> 15.72 x 40
=> $628.8
After federal withholding tax, then the amount is
=> $628.8 - 69
=> $559.8
Now the tax is 4.63%, then
=> $559.8 x 4.63%
=> $559.8 x (4.63/100)
=> $25.91
So, the remaining amount is
=> $559.8 - $25.91
=> $533.88
Now, he will receive 5% for his hourly rate,
Then,
=> $15.72 x (5%)
=> $15.72 x (5/100)
=> 0.78
So, the increased amount is
=> $16.5
Now, the net pay is,
=> (16.5 * 40) - (75 + 25.91)
=> 660 - 100.91
=> 599.09
So, Ted's net pay per paycheck, after taxes is $559.09.

The area of a triangle is [tex]\frac{1}{2} (bh)[/tex].
The height is already given: 8
But we need to find the base and since the hypotenuse is given and it's a right triangle, we can use the pythagorean theorem. (Hypotenuse is longest, slanted side of a right triangle)
The pythagoren theorem is [tex]a^2+b^2=c^2[/tex] where a and b are the sides, and c is the hypotenuse.
Plugging in the given values => [tex]8^2+b^2=10^2[/tex]
We have to solve for b. So, squaring 8 and 10 we get [tex]64+b^2=100[/tex].
Next, subtract 64 from both sides to get b by itself: [tex]b^2=36[/tex]
Square root both sides to get [tex]b=6[/tex].
Now that we have our base we can plug it in to the area of triangle formula: [tex]1/2(6*8)[/tex].

Using the equation of the parabola, the inequality represented is:

What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
For this problem, the vertex is at (-2,8), hence:
h = -2, k = 8.

4 = 4a + 8
4a = -4
a = -1.
Hence the parabola is:
y = -(x + 2)² + 8.

The location of the midpoint of the line segment is (37 / 2, 11 / 2).
How to determine the location of the midpoint in a line segment
According to the statement, the position of the two endpoints of a line segment are known and we must determine where the midpoint is, that is, the point such that the line segment is divided into two parts of equal length. The location of the midpoint is found by means of the midpoint formula:
M(x, y) = 0.5 · B(x, y) + C(x, y)
Where M(x, y) is the midpoint.
If we know that B(x, y) = (15, 7) and C(x, y) = (22, 4), then the location of the midpoint is:
M(x, y) = 0.5 · (15, 7) + 0.5 · (22, 4)
M(x, y) = (15 / 2, 7 / 2) + (11, 2)
