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

Write the equation of the circle with the given information.
Center: (2,8)
Radius: 3

Answers

Answer:

(x - 2)² + (y - 8)² = 9

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (2, 8 ) and r = 3 , then

(x - 2)² + (y - 8)² = 3² , that is

(x - 2)² + (y - 8)² = 9

You have 2 different savings accounts. For Account​ A, the simple interest earned after months is ​$1.90. For Account​ B, the simple interest earned after 18 months is ​$22.05. If the interest rate is 3.8% for Account A and 2.1% for Account​ B, how much is the principal in each​ account? Which account earned you the most interest the first​ month? Explain your answer.

Please help i need to turn it in soon!!

Answers

Answer:

The computation is shown below;

As we know that

The simple interest is

Simple interest = Principal × rate × time

For Account A, the principal would be

2 = Principal × 3.2% × 3

So, the principal is $20.83

For account B, the principal would be

38.50 = Principal × 2.2% × 30

So, the principal is $58.33

Now the interest for both the accounts are as follows

For account 1

= $20.83 × 3.2%

= $0.67

And, for the account 2

= $58.33 × 2.2%

= $1.28

As it can be seen that the account 2 has the highest interest

The same is to be considered

Erica saw a skateboard on sale for $45.56. The original price of the skateboard was $75.99. What is the approximate percent discount on the skateboard? Round to the nearest whole percent.

Answers

Answer:

60%

Step-by-step explanation:

45.56/75.99 x 100 = 59.9

Rounded = 60%

Hello!

Discounts! I struggle myself with these, but a common method can help you find the price.

First, we'll subtract 45.56 from 75.99, to get our discount factor.

75.99 - 45.56 = 30.43

Now, we have to figure out the percentage of said factor. How much of 75.99 is 30.43. We must divide discount factor by original number.

30.43 ÷ 75.99 = 0.40044742729306 which would be equal to 40.044742729306%

Lastly we round 40.044742729306% to the nearest whole percent.

Our final answer is: 40%

Determine the probability of drawing either a jack or a spade?
Write ydur answer as a reduced fraction.
Answer =

Answers

Answer:

First Answer = 2/13

Second Answer = 4/13

Step-by-step explanation:

1. There are 52 cards in a standard deck. There is also a total of 4 jacks and 4 queens of these 52 cards. So, the probability of drawing either a jack or a queen after one pick would be 8/52 = 2/13.

2. There are 4 jacks, and 13 spades. However, one of those jacks is a jack of spades. So, instead of 17 possible picks, one overlaps, resulting in 16 possible picks. This is represented by 16/52 = 4/13.

The probability of drawing either a jack or a queen is 2/13 or 15.38%. In turn, the probability of drawing either a jack or a spade is 15/52 or 28.84%

Since Jenelle draws one card from a standard deck of 52 cards, to determine the probability of drawing either a jack or a queen, and to determine the probability of drawing either a jack or a spade, the following calculations must be performed:

Jack + Queen = 4 + 48/52 = X2/13 = X0.1538 = X

Jack + Spade = 4 + 1115/52 = X0.2884 = X

Use the net to find the surface area of the prism.



96 in2

12 in2

24 in2

84 in2

Answers

Answer:

a. 96 in²

Step-by-step explanation:

The surface area of the prism = the sum of the area of each part of the net shown

✔️Area of the 2 equal triangles = 2(½*b*h)

b = 4 in

h = 3 in

Area of the two triangles = 2(½*4*3) = 12 in²

✔️Area of the rectangle 1 with the following dimensions:

L = 7 in

W = 3 in

Area = L*W = 7*3 = 21 in²

✔️Area of the rectangle 2 with the following dimensions:

L = 7 in

W = 4 in

Area = L*W = 7*4 = 28 in²

✔️Area of the rectangle 3 with the following dimensions:

L = 7 in

W = 5 in

Area = L*W = 7*5 = 35 in²

✅Surface area of the prism = 12 + 21 + 28 + 35 = 96 in²
