The sign of each coefficient indicates the direction of the relationship between a predictor variable and the response variable. A positive sign indicates that as the predictor variable increases, the response variable also increases.
What do the estimates of the regression coefficients tell us?
You may determine if each independent variable and the dependent variable have a positive or negative association by looking at the sign of a regression coefficient. A positive coefficient means that the mean of the dependent variable tends to rise when the value of the independent variable rises.
What is predictor and response variable in regression?
The risk factors and confounders are referred to as the predictors, or explanatory or independent variables, whereas the outcome variable is also known as the response or dependent variable. The independent variables are designated by "X" while the dependent variable is denoted by "Y" in regression analysis.

Part A:
The number of outcomes that each of them will have to choose anyone at random is calculated below.
n = 3 x 3 = 9
This is because, Al will have 3 choices and similarly, Bill will also have three choices. These outcomes are as written below.
S = (1,1), (1,2), (1,3), (2, 1), (2,2), (2, 3), (3, 1), (3, 2), and (3,3)
Part B: To make the same choice, there will only be three outcomes. These are:
S = (1, 1), (2, 2) and (3, 3)
Part C: If neither of them will vote for 2, there will only be four outcomes. This is because each of them will only have two choices. These are:
S = (1, 1), (1, 3), (3, 1), and (3,3)
Answer:
max profit at MR = MC is 1,562.5 dollars
Explanation:
we need to solve for the point at which MR = MC
First we calculate marginal revenue, the revenue generate from an additional units which, is the slope of the revenue function
p = 70 - 0.1Q
total revenue = (70 - 0.1Q)Q = -0.1Q^2 + 70Q
dR/dq= -0.2q + 70
Then we do the same for marginal cost, the cost to produce another unit:
total cost: 1,500 + 35 Q
dC/dq = 35
Now we equalize and solve:
-0.2q + 70 = 35
70 - 35=0.2q
35/0.2 = q = 175
p = 70 - 0.1 (175) = 70 - 17.5 = 52.5
52.5Q - 1,500 - 35Q = profit
52.5 x 175 - 1500 - 35 x 175 = profit
profit = 1562.5
if we calcualte for one up or down:
Q = 174 then profit = 1562.4
Q = 176 then profit = 1562.4
This profit is lower than our maximize point, so we agree this is the max point.
Answer:
1. Benefits Of Regional Economic Integration
2. Enhanced political cooperation. Several nations usually have a much larger political influence as compared to the influence that each individual country would have.
3. Creates trade. Member countries in a regional economic integration agreement have a wider choice of services and goods that were previously unavailable.
<em>4. Employment prospects. </em>
Explanation:
The benefits of regional integration can easily identify. There are economic benefits such as additional trade, improved quality, increased imports and exports, high-quality international relations and an integrated market. Regional integration can enhance the general quality of life for the citizens of those states.
Answer:
March 1, purchased securities from Benton Corporation:
Dr Investment in securities 500,000
Cr Cash 500,000
May 1, sold half of securities plus accrued interest:
Dr Cash 248,550
Dr Loss on investment in securities 5,000
Dr Brokerage fees 200
Cr Investment in securities 250,000
Cr Interest revenue 3,750
Securities were sold at 98 or $250,000 x 98% = $245,000, which means that the company lost $5,000 with that investment.
