The correct statements about omitted variable bias are:

1. If the omitted variable and included variable are correlated, there is a bias.

2. If the omitted variable is relevant, there is a bias.

Omitted variable bias refers to the bias introduced in an econometric model when a relevant variable is left out of the analysis. The bias occurs when the omitted variable is correlated with both the dependent variable and the included variables in the model.

If the omitted variable and included variable are correlated, there is a bias because the included variable may capture some of the effects of the omitted variable. In this case, the estimated coefficient of the included variable will be biased, as it will include the influence of the omitted variable.

Similarly, if the omitted variable is relevant, there is a bias because it has a direct impact on the dependent variable. By excluding the relevant variable, the model fails to account for its influence, leading to biased estimates of the coefficients of the included variables.

Random assignment of included variables does not eliminate omitted variable bias. While random assignment may help control for confounding factors and reduce bias in certain experimental designs, it does not address the issue of omitting a relevant variable from the analysis. Omitted variable bias can still exist even with random assignment of included variables.

The model that represents number y of customers that the restaurant serves x years after 2012 is y = 700x + 27000

The restaurant will serve 32600 customers in 2020

Since 2012 is the initial year:

In year 2012, x₁ = 0

Number of customers served in 2012, y₁ = $27000

In year 2014, x₂ = 2

Number of customers served in 2014,

y₂ = $28400

The slope can be calculated using the formula:

\(m = \frac{y_2 -y_1}{x_2 - x_1} \\ \)

\(m \: = \frac{28400 - 27000}{2 - 0} \)

m = 700

The model is linear and it will be given by the general equation:

\(y - y_1 = m(x - y_1)\)

\(y - 27000 = 700(x - 0)\)

\(y = 700x + 27000\)

The linear model is:

y = 700x + 27000

In 2020, x = 8

The number of customers the restaurant will serve in 2020 will be calculated by substituting

x = 8 into the model

y = 700(8) + 27000

y = 5600 + 27000

y = 32600

The restaurant will serve 32600 customers in 2020

The divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k is 20x - 2zcos(xz).

To find the divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k, you need to take the divergence operator (∇ · F).

The divergence of a vector field in Cartesian coordinates is given by the following formula:

∇ · F = (∂Fx/∂x) + (∂Fy/∂y) + (∂Fz/∂z),

where Fx, Fy, and Fz are the x, y, and z components of the vector field F, respectively.

In this case, we have:

Fx = (5x^2 + 7 - sin(xz)),

Fy = 0, and

Fz = (5x^2 + 7 - sin(xz)).

Taking the partial derivatives, we get:

∂Fx/∂x = 10x - zcos(xz),

∂Fy/∂y = 0, and

∂Fz/∂z = 10x - zcos(xz).

Now, substituting these derivatives into the divergence formula, we have:

∇ · F = (10x - zcos(xz)) + 0 + (10x - zcos(xz)).

Simplifying further, we get:

∇ · F = 20x - 2zcos(xz).

Therefore, the divergence of the vector field F(x, y, z) = (5x^2 + 7 - sin(xz))i + 0j + (5x^2 + 7 - sin(xz))k is 20x - 2zcos(xz).

Answer:

The average GPA would be 1.8

Step-by-step explanation:

Hope this is helpful. I did a test like this exact question and I got it right.

the point P_0(2,1,2) lies on the tangent plane, we can use it to find the equation of the normal line:

x - 2 = 2

We start by finding the characteristic equation:

r^2 + 4r + 3 = 0

Solving for r, we get:

r = -1 or r = -3

So the complementary solution is:

y_c(t) = c_1 e^{-t} + c_2 e^{-3t}

Next, we need to find the transfer function H(s):

s^2 Y(s) - s y(0) - y'(0) + 4s Y(s) - 4y(0) + 3Y(s) = 1/s + 1/(s-1)

Applying the initial conditions y(0) = 0 and y'(0) = 1, we get:

(s^2 + 4s + 3) Y(s) = 1/s + 1/(s-1) + 4

Y(s) = [1/(s+1) + 1/(s+3) + 4/(s^2 + 4s + 3)] / (s^2 + 4s + 3)

We can factor the denominator of the second term in the numerator:

Y(s) = [1/(s+1) + 1/(s+3) + 4/((s+1)(s+3))] / [(s+1)(s+3)]

Using partial fraction decomposition, we get:

Y(s) = [2/(s+1) - 1/(s+3) + 1/((s+1)(s+3))] / (s+1) + [-1/(s+1) + 2/(s+3) - 1/((s+1)(s+3))] / (s+3)

Taking the inverse Laplace transform, we get:

y(t) = 2e^{-t} - e^{-3t} + (1/2)(1 - e^{-t}) - (1/2)(1 - e^{-3t})

So the general solution is:

y(t) = y_c(t) + y_p(t) = c_1 e^{-t} + c_2 e^{-3t} + 2e^{-t} - e^{-3t} + (1/2)(1 - e^{-t}) - (1/2)(1 - e^{-3t})

To find a particular solution, we need to solve for the unknown coefficients. Using the initial conditions y(0) = 1 and y'(0) = 0, we get:

c_1 + c_2 + 3/2 = 1

-c_1 - 3c_2 - 1/2 = 0

Solving this system of equations, we get:

c_1 = -2/5

c_2 = 9/10

So the particular solution is:

y_p(t) = (-2/5) e^{-t} + (9/10) e^{-3t} + (1/2)(1 - e^{-t}) - (1/2)(1 - e^{-3t})

Finally, the tangent plane at P_0(2,1,2) is given by the equation:

2x + 4y + 3z = 24

which corresponds to option (B) in the given choices.

To find the normal line, we first need to find the normal vector to the tangent plane, which is simply:

n = <2, 4, 3>

Answer:

g(x) = |x+1| + 2

Step-by-step explanation:

In functions for horizontal shifts left or right we look at 'h' in the absolute value function formula: f(x) = a |x-h| +k, the h is opposite of what we think in functions here. an h value of 4 would indicate 4 to the left, -4 would indicate 4 to the right. Since we move 4 to the left we have '+4' and add that to the -3 in the function, giving us a h value of -1, so the new function would be g(x) = |x+1| + 2

Answer:

x = -24

Step-by-step explanation:

If you are to solve for x then multiply everything by 2 so

\(\frac{2x}{8}\) - 1 = -7 now multiply everything by 8 to get rid of the fraction

2x - 8 = -56, solve for x so 2x = -48 so x = -24

Thus, the concept of multiplying decimals by powers of 10 is used.

a) 8.7 x 10 = 87.0

b 8.7 x 100 = 870.0

C 8.7 x 1,000 = 8700.0

d 8.7 x 0.1 = 0.87.

e 8.7 x 0.01 = 0.087.

a) When we multiply 8.7 by 10, we move the decimal point one place to the right, giving us 87.0. However, the zero at the end is not significant, so we can drop it, leaving us with 8.7.

b) When we multiply 8.7 by 100, we move the decimal point two places to the right, giving us 870.0. Again, the zero at the end is not significant, so we drop it, leaving us with 87.

c) When we multiply 8.7 by 1,000, we move the decimal point three places to the right, giving us 8,700.0. Once again, we drop the zero at the end, leaving us with 8,700.

d) When we multiply 8.7 by 0.1, we move the decimal point one place to the left, giving us 0.87.

e) When we multiply 8.7 by 0.01, we move the decimal point two places to the left, giving us 0.087.

f) If we look at the answers for parts a through e, we can see that the number of zeroes and the position of the decimal point change based on the power of 10 we are multiplying by. When we multiply by a larger power of 10, we add more zeroes and move the decimal point further to the right. When we multiply by a smaller power of 10, we move the decimal point to the left and the number of zeroes decreases.

In conclusion, multiplying decimals by powers of 10 can change the position of the decimal point and the number of significant figures in the answer. It is important to pay attention to the placement of the decimal point and the number of zeroes in the answer to ensure accuracy.

The  total number of ways to arrange 3 copies of introduction to geometry and 4 copies of introduction to number theory on a bookshelf is 35.

A permutation of a set of objects is an ordering of those objects. When some of those objects are identical, the situation is transformed into a problem about permutations with repetition. Problems of this form are quite common in practice; for instance, it may be desirable to find orderings of boys and girls, students of different grades, or cars of certain colors, without a need to distinguish between students of the same grade (or cars of the same color, or people of the same gender).

Total number of copies = 3 +4 = 7

Number of ways to arrange 7 copies together = 7!

However, there are 3 copies of introduction to geometry and 4 copies of introduction to number theory. Thus, all copies of each book are identical.

Now, the total number of ways to arrange 7 copies together

= \(\frac{7!}{3!* 4!}\)

=35

Thus, the  total number of ways to arrange 3 copies of introduction to geometry and 4 copies of introduction to number theory on a bookshelf is 35.

Step-by-step explanation:

We know that the speed of light is about 3 × 10 ^ 8 meters per second and that the speed of sound in dry air is about 3 × 10 ^ 2 meters per second. We need to solve 3 × 10 ^ 8 minus 3 × 10 ^ 2.

3 × 10 ^ 8 - 3 × 10 ^ 2 =

The total number of matches played in the tournament will be the sum of all of these matches:
475 + 220 + 92 + 40 + 18 + 8 + 4 + 2 + 1 + 1 = 861

To determine the total number of matches to be played in the tournament, we need to first determine the number of rounds that will be played. Since each round eliminates half of the remaining players, we need to find the power of 2 that is closest to, but less than, the total number of players (951).

2^9 = 512 (too small)
2^10 = 1024 (too big)
2^8 = 256 (too small)
2^7 = 128 (too small)
2^6 = 64 (too small)
2^5 = 32 (too small)

Therefore, we can conclude that there will be 2^9 = 512 players in the first round, leaving 439 players. One player will be sitting out, since the number of players is odd. In the second round, there will be 2^8 = 256 matches played, with the 439 remaining players and the one player who sat out in the first round. This will leave 184 players for the third round, with one player sitting out again.

Continuing this pattern, we can determine that there will be 10 rounds in total, with the following number of matches played in each round:

Round 1: 475
Round 2: 220
Round 3: 92
Round 4: 40
Round 5: 18
Round 6: 8
Round 7: 4
Round 8: 2
Round 9: 1
Round 10: 1

The total number of matches played in the tournament will be the sum of all of these matches:

475 + 220 + 92 + 40 + 18 + 8 + 4 + 2 + 1 + 1 = 861

Therefore, there will be a total of 861 matches played in all the rounds of the tournament.

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

Total 1,512,000 "words" can be formed by rearranging INQUISITIVE so that U does not immediately follow Q.

In the given question, we have to find how many "words" can be formed by rearranging INQUISITIVE so that U does not immediately follow Q.

The given word is INQUISITIVE.

The total alphabets in the word INQUISITIVE is 11.

Let us first count the words without U and then insert U wherever applicable.

Now without U we have total 10 alphabets and the alphabet I is repeated by 4 times.

So permutations is 10!/4! = 151,200

Now we need to put U, we can see its 11 alphabets but U should not follow Q so it becomes 10 alphabets.

Hence, Total number of words = 151,200*10

Total number of words = 1,512,000

Hence, 1,512,000 "words" can be formed by rearranging INQUISITIVE so that U does not immediately follow Q.
