The OLS residuals in the multiple regression model: A) cannot be calculated because there is more than one explanatory variable. B) can be calculated by subtracting the fitted values from the actual values. C) are zero because the predicted values are another name for forecasted values. D) are typically the same as the population regression function errors.
Answer:
B) can be calculated by subtracting the fitted values from the actual values.
Step-by-step explanation:
'Multiple Regression Model' is characterized as the further augmentation of the 'linear regression model.' which is employed to predict a dependent variable's value on the basis of other provided variables(independent). It also helps in showing the linear association among these variables.
In this model, the OLS residuals can be determined by deducting the adapted values from the real values. Thus, there would be a subtraction of the calculated value from the predicted value to find the value of residual. The 'distinction between the actual and fitted values itself is characterized as the residual.' Therefore, option B is the correct answer.

Answer:
you have to suppose a imaginary parallel line at E cutting the angle b and find both angles by alternate and add them.
Which equation represents a line which is parallel to the line 3x - y = 6?
Any equation of the form,
⇒ y = 3x + b,
where b is a constant, represents a line parallel to the line 3x - y = 6.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Now, To find the equation of a line that is parallel to 3x - y = 6, we need to find the slope of the line 3x - y = 6.
Hence, we can rearrange the equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
3x - y = 6
-y = -3x + 6
y = 3x - 6
Therefore, the slope of the line 3x - y = 6 is,
m = 3.
Since we want a line that is parallel to this line, the slope of the new line must also be 3.
Thus, Any equation of the form,
⇒ y = 3x + b,
where b is a constant, represents a line parallel to the line 3x - y = 6.

The area of a rectangle is 14 in. The length of one side is 7 in. What is its perimeter?
Answer:
The answer is 18
hope this helps
have a good day :)
Step-by-step explanation:
Answer:
The perimeter of the rectangle =18 in
Step-by-step explanation:
Given, Area of rectangle= 14 in
Length(l) of one side = 7 in
We know,
Area = lxb
or, 14 = 7xb
or, b = 2 in
then the perimeter of the rectangle = 2x(l+b)
= 2x(7+2)
= 2x9

The zeros of a parabola are 6 and -5. If (-1, 3) is a point on the graph, which equation can be solved to find the
value of a in the equation of the parabola?
O3 = a(-1 + 6)-1-5)
O 3 = a(-1-6)(-1 +5)
O -1 = a(3+6)(3-5)
O-1 = a(3-6)(3+5)
Answer:
3 = a(-1-6)(-1+5).
Step-by-step explanation:
y = a(x - 6)(x + 5)
When x = -1, y = 3 so we have:
3 = a(-1-6)(-1+5).

Find the quotient of z1 by z2. .Express your answer in trigonometric form.
Answer:
[tex]\frac{z_1}{z_2} = 3(cos(240^o) + isin(240^o))[/tex]
Step-by-step explanation:
Given
[tex]z1 = 12(cos(320^o) + isin(320^o))[/tex]
[tex]z2 = 4(cos(80^o) + isin(80^o))[/tex]
Required
[tex]Quotient = \frac{z_1}{z_2}[/tex]
We have:
[tex]Quotient = \frac{12(cos(320^o) + isin(320^o))}{4(cos(80^o) + isin(80^o))}[/tex]
Divide 12 by 4
[tex]Quotient = \frac{3(cos(320^o) + isin(320^o))}{(cos(80^o) + isin(80^o))}[/tex]
Solve using the following rule:
[tex]\frac{(cos(a) + isin(a))}{(cos(b) + isin(b))} = \cos(a - b) + isin(a - b)[/tex]
So, we have:
[tex]Quotient = \frac{3(cos(320^o) + isin(320^o))}{(cos(80^o) + isin(80^o))}[/tex]
[tex]Quotient = 3(cos(320^o-80^o) + isin(320^o-80^o))[/tex]
[tex]Quotient = 3(cos(240^o) + isin(240^o))[/tex]
Hence:
[tex]\frac{z_1}{z_2} = 3(cos(240^o) + isin(240^o))[/tex]

two objects are 2.4*10^20 centimeters apart. a messages from one object travels to the other at a rate of 1.2*10^5 centimeters per second. how many seconds does it take the message to travel from one object to the other
Answer:
2 · 10¹⁵ seconds
Step-by-step explanation:
1.2 · 10⁵
2.4 · 10²⁰
2.4 · 10²⁰ ÷ 1.2 · 10⁵
2 · 10²⁰ ⁻ ⁵
2 · 10¹⁵
It took the message 2 × 10¹⁵ seconds to travel from one object to the other.
To be able to solve this problem, we need to understand the relation between speed and distance.
What are Speed and Distance?Speed is the change of an object's position with time, the distance is the space covered with a specified range of time.
The relation between Speed and distance can be expressed by using the relation:
[tex]\mathbf{speed = \dfrac {distance}{time}}[/tex]
From the parameters given:
Speed = 1.2 × 10⁵ cm/sDistance = 2.4 × 10²⁰ cm Time = (unknown)???The time it took the message to travel from one object to the other can be determined by making time(t) the subject of the formula from the above equation:
i.e.
[tex]\mathbf {time = \dfrac{distance} {speed}}[/tex]
[tex]\mathbf {time = \dfrac{2.4 \times 10^{20}\ cm} {1.2 \times 10^5 \ cm/s}}[/tex]
time = 2 × 10¹⁵ seconds

What is the distance between points L(−5, 7) and M(3, −8)?
Answer:
17
Step-by-step explanation:
√(3-(-5))²+(-8-7)²
√(3+5)²+(-15)²
√8²+225
√64+225
√289
=17
The distance between two points L(-5, 7) and M(3, -8) is 17 units.
What is distance ?Distance is a numerical measurement of how far apart objects or points are. In Physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.
Here Distance formula = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]
Distance = [tex]\sqrt{(3-(-5))^{2} + (-8-7)^{2} }[/tex]
D = [tex]\sqrt{8^2+15^2}[/tex]
D =[tex]\sqrt{64 + 225}[/tex]
D = [tex]\sqrt{289}[/tex]
D = 17 units
Thus, the distance between two points L(-5, 7) and M(3, -8) is 17 units.

Gentile, Lynch, Linder, and Walsh (2004) surveyed over 600 8 th- and 9th-grade students asking about their gaming habits and other behaviors. Their results showed that adolescents who experienced more video game violence were also more hostile and had more frequent arguments with teachers. Is this an experimental or a nonexperimental study? Explain your answer.
Answer: nonexperimental study
Instead, this is a survey
==================================================
Explanation:
We have a survey being conducted because the researchers are asking the students the questions. It's not an experiment because the students aren't being broken up into two groups (control group vs treatment group) to see the difference between the two if any.
