A researcher plans to study the causal effect of a strong legal system on economy, using data from a random sample of U.S. counties. The researcher plans to regress national income per capita on whether the country has a strong legal system or not (an indicator variable taking the value 1 or 0, based on expert opinion). Do you think this regression suffers from omitted variable bias
Answers
Answer:
Based on expert opinion the regression does not suffer from omitted variable bias
Step-by-step explanation:
Based on expert opinion the regression does not suffer from omitted variable bias because its indicators taking values of 1 and 0 where 1 would represent taking action by the legal system and 0 would represent not taking action by the legal system. as
The researcher plans to regress national income per capita based on the effect of the legal system
applying the formula for addressing omitted variable bias ( attached below )

Answers
Answer:
$641
Step-by-step explanation:
Let $p be the original price.
[tex](1 - 25\%)p = 481 \\ \frac{75}{100} p = 481 \\ p = 641[/tex]

Answer :
A cylinder has a radius of 5 m and a height of 11 m. Identify the volume of the cylinder to the nearest tenth.
Answers
Answer:
86,405 cm³
Step-by-step explanation:
V = cross-sectional area × height = πr²h = 3.142 × 5² × 1100cm
= 86,405 cm³
Answer:
863.9 m³
Step-by-step explanation:
Cylinder volume is V = πr²h. Here the height, h, is 11 m and the radius, r, is 5 m. Thus we have:
V = π(5 m)²(11 m), or
V = π(275) m³, or approximately 863.9 m³

What is the perimeter of the track, in meters? Use tt 3.16 and round to the nearest hundredth of a meter
Answers
Answer:
The perimeter of the track is of 317 meters.
Step-by-step explanation:
Perimeter:
The perimeter of a figure is the sum of all its dimensions.
In this question:
The track is composed by two straights of 80m, and two half circles with a diameter of 50m.
Perimeter of a circle:
The perimeter of a circle with diameter d is of:
[tex]P = \pi d[/tex]
Track:
Two half circles, each with a diameter of 50m, plus two straight lines of 80m. So
[tex]P = \frac{2\pi}{2}(50) + 2*80) = 50\pi + 160 = 50*3.14 + 160 = 317[/tex]
The perimeter of the track is of 317 meters.

Use the graph below to find the indicated function Value. y=f(x); f(4)
Answers
then y=3
The value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The graph of the function is shown in the picture.
From the graph the value of f(4) can be evaluated as follows:
y = f(x)
Plug x = 4
y = f(4)
From the graph:
Draw a vertical line from point 3 on the x-axis and when it cuts the curve draw a horizontal line when the line cuts the y-axis note the point.
y = f(4) = 3
Thus, the value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.

Jason drew a triangle to explain the Triangle Sum Theorem and labeled the angles 1, 2, and 3
He tore each angle off the triangle so he could move the three angles around.
What should Jason do next to explain the Triangle Sum Theorem?
Jason should line up the angles next to each other as adjacent angles to show that the 3 angles together form a straight angle.
Jason should create a new triangle by moving the angles closer together to show that the 3 angles can create other triangles.
Jason should fold each angle in half to show each angle with one half of the measure it had in the triangle.
Jason should stack the angles on top of each other to show that the 3 angles have the same measures.
Answers
Answer:
A
Step-by-step explanation:
Well B is strange. You might get them to make one complementary angle, but that has nothing to do with the Triangle sum theorem.
C is true. He is getting similar triangles, but that does not prove the Triangle sum theorem. So -- don't choose C
D is just taking up space so you get 4 choices.
The answer should be A but the problem is the tips of the angles should all come to the same place. I think it does mean A, but it is a bit awkwardly worded.
