Answer:
The value of residual is 2.5131%.
Step-by-step explanation:
We are given the following in the question:
![\hat{y}= -4.599 +1.04x](https://tex.z-dn.net/?f=%5Chat%7By%7D%3D%20-4.599%20%2B1.04x)
The above is a linear regression equation to predict the percentage of people in a state that would vote for Obama in 2012 based on the percentage of people in a state that voted for Obama in 2008.
Independent Variable:
Percentage of people in a state that voted for Obama in 2008
Dependent Variable:
Percentage of people in a state that would vote for Obama in 2012
In the state of Florida, 50.09% voted for Obama in 2008; whereas, 50.01% voted for him in 2012.
Thus, the actual value is 50.01%.
We predict the value from regression equation by putting x = 50.09
![\hat{y}= -4.599 +1.04(50.09) = 47.4946](https://tex.z-dn.net/?f=%5Chat%7By%7D%3D%20-4.599%20%2B1.04%2850.09%29%20%3D%2047.4946)
The predicted value for percentage of people in a state that would vote for Obama in 2012 is 47.4969%.
Residual is the difference between the predicted value and the actual value.
![\text{Residual} = \text{Observed - Predicted}\\= y-\hat{y}\\= 50.01\% - 47.4969\%\\= 2.5131\%](https://tex.z-dn.net/?f=%5Ctext%7BResidual%7D%20%3D%20%5Ctext%7BObserved%20-%20Predicted%7D%5C%5C%3D%20y-%5Chat%7By%7D%5C%5C%3D%2050.01%5C%25%20-%2047.4969%5C%25%5C%5C%3D%202.5131%5C%25)
Thus, the value of residual is 2.5131%.

Answer:
Step-by-step explanation:
Cost of cheese = x
Cost of meat = 4*x = 4x
Cost of milk = (1/2)x
Equation that helps to find the cost of cheese:
![\frac{1}{2}x+x+4x=48](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dx%2Bx%2B4x%3D48)
