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.

Answers

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.

The area of a rectangle is 14 in. The length of one side is 7 in. What is its perimeter?

Answers

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

=18in

Gentile, Lynch, Linder, and Walsh (2004) surveyed over 600 8 th- and 9th-grade students asking about their gaming habits and other behaviors.

Find the quotient of z1 by z2. .Express your answer in trigonometric form.

Answers

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]

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)

Answers

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).

Lorenzo wants to know how much it will cost to rent tables and chairs for an event. He investigates renting tables and chairs and decides to use two different companies. Company A $4 per table (seats 4) and a $25 one-time delivery and pickup fee Company B $2 per chair and a $15 one-time delivery and pickup fee Each table seats 4 people, so Lorenzo needs to rent 4 chairs for every table. x = number of tables Cost to rent tables from Company A: f(x) = 4x + 25 Cost to rent chairs from Company B: g(x) = 2(4x) + 15 Which function represents the total cost for Lorenzo to rent x number of tables and the chairs he needs to go with them? 12x 12x2 + 40 12x + 40 8x + 40

Answers

Answer:

C: 12x + 40

Step-by-step explanation:

We are told that the Cost to rent tables from Company A is;

f(x) = 4x + 25

Also, we are told that the Cost to rent tables from Company B is;

g(x) = 2(4x) + 15

Thus, total cost for Lorenzo to rent x number of tables and the chairs he needs is;

Total = f(x) + g(x)

Total = 4x + 25 + 2(4x) + 15

Total = 4x + 25 + 8x + 15

Total = 12x + 40

What is the distance between points L(−5, 7) and M(3, −8)?

Answers

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.

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

Answers

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
