Answers
Answer:
(2, –3) is a solution to the system of linear equations.
Step-by-step explanation:
Given: Equations:
3x - y = 9 --------(1),
4x + y = 5 --------(2),
Add Equation (1) + Equation (2),
3x + 4x = 9 + 5
7x = 14 ( Combine like terms )
x = 2 ( Divide both sides by 7 ),
From equation 1:
3(2) - y = 9
6 - y = 9
-y = 9 - 6 ( Subtraction 6 on both sides )
-y = 3
y = - 3 ( Multiplying -1 on both sides )

Find the 14th term of the arithmetic sequence x-1x−1, 7x-77x−7, 13x-13, ...13x−13,...
Answers
The 14th term of the arithmetic sequence x-1x−1, 7x-77x−7, 13x-13, ...13x−13,... is -79.
The nth term of a particular arithmetic sequence can be found by, an = a + (n – 1)d. So in order to find the nth term, substitute the given values \(a_{1}\) and d into the formula. So to find the 14th term, substitute n = 14 into the equation which is the nth term.
Given,
\(a_{1}\)= x-1x-1
\(a_{2}\)= 7x-77x−7
\(a_{3}\)= 13x-13
n= 14
We have to find the common difference d from differences in adjacent terms \(a_{1}\),\(a_{2}\),\(a_{3}\) . That is,
\(a_{2}-a_{1} =a_{3} -a_{2}\)
\(7x-77x-7-(x-1x-1)=13x-13-(7x-77x-7)\)
\(7x-77x-7-x+x+1=13x-13-7x+77x+7\\-70x-8x=-6+6\\-78x=0\\ x=0\)
Put x=0 in x-1x-1, 7x-77x-7, 13x-13
Therefore,
\(a_{1}\) = -1
\(a_{2}\) = -7
\(a_{3}\) = -13
Then, d will be \(-7-(-1)\) or \(-13-(-7)\)
So, d= -6
Put \(a_{1}\), d, and n in the equation \(a_{n} =a+(n-1)d\) to find the 14th term.
Therefore,
\(a_{14}=-1+(14-1)-6\\ =-1-78\\=-79\)
The 14th term of the given arithmetic sequence is -79

Bill's Grill is a popular college restaurant that is famous for its hamburgers. The owner of the restaurant, Bill, mixes fresh ground beef and pork with a secret ingredient to make delicious quarterpound hamburgers that are advertised as having no more than 25% fat. Bill can buy beef containing 80% meat and 20% fat at $0.85 per pound. He can buy pork containing 70% meat and 30% fat at $0.65 per pound. Bill wants to determine the minimum cost way to blend the beef and pork to make hamburgers that have no more than 25% fat. For every problem: 1. Formulate an LP model 2. Find the optimal solution by using Excel Solver and submit Excel Template with your solution results. 3. Provide an interpretation of the Sensitivity Report.
Answers
The main answer is to set up a linear programming model to minimize the cost of the hamburger mixture while satisfying the fat and meat content constraints, and then use Excel Solver to find the optimal solution.
To formulate an LP model for Bill's Grill problem, let's define the decision variables and the objective function:
Decision Variables:
Let x be the amount of beef (in pounds) used in the hamburger mixture.
Let y be the amount of pork (in pounds) used in the hamburger mixture.
Objective Function:
Minimize the cost of the hamburger mixture: Cost = 0.85x + 0.65y
Subject to the following constraints:
1. Fat Constraint: The fat content in the hamburger mixture should be no more than 25%.
0.20x + 0.30y ≤ 0.25(x + y)
2. Meat Constraint: The meat content in the hamburger mixture should be at least 75%.
0.80x + 0.70y ≥ 0.75(x + y)
3. Non-negativity Constraint: The amounts of beef and pork used should be non-negative.
x ≥ 0
y ≥ 0
By solving this linear programming model using Excel Solver, you can find the optimal solution that minimizes the cost while satisfying the fat and meat content constraints. The sensitivity report generated by Excel Solver will provide valuable information about the solution, including the shadow prices (dual values) associated with the constraints, which represent the rate of change in the objective function with respect to the constraint coefficients.
Please note that the Excel template and detailed solution results would require a specific file format that cannot be provided through this text-based interface. I recommend using Excel software with Solver add-in to set up and solve the LP model for Bill's Grill problem.

determine which of the following (if any) regarding multicollinearity are true. i. we can calculate the amount of collinearity by using the vif. ii. if some predictor variables in the model are highly correlated with each other, this will generally have no impact on the model. iii. when an f test is significant, but none of the t tests are significant, we can rule out multicollinearity as the cause.
Answers
The first statement is true, while the second and third statements are false. Multicollinearity can impact the model and can lead to misleading results, even if some predictor variables are highly correlated with each other. Additionally, the significance of F-test alone cannot rule out the possibility of multicollinearity.
i. The first statement is true. The Variance Inflation Factor (VIF) can be used to measure the amount of collinearity in the model. VIF is a measure of the amount of correlation between a predictor variable and the other predictor variables in the model. Higher VIF values indicate higher levels of collinearity. Typically, a VIF value greater than 10 indicates a problematic level of collinearity.
ii. The second statement is false. If some predictor variables in the model are highly correlated with each other, it can lead to multicollinearity, which can impact the model's results. Multicollinearity can make it difficult to interpret the individual effect of each predictor variable on the outcome variable, and it can also increase the standard errors of the regression coefficients. This can result in reduced statistical power, decreased predictive accuracy, and misleading results.
iii. The third statement is also false. A significant F-test indicates that at least one of the predictor variables in the model is related to the outcome variable, but it does not rule out the possibility of multicollinearity. If none of the t-tests are significant, it could be due to a lack of statistical power or the presence of multicollinearity, which can make it difficult to detect the individual effects of each predictor variable.
To test for multicollinearity, one can examine the VIF values or use other diagnostic tests, such as the condition number or tolerance values. If multicollinearity is detected, one can consider removing one of the highly correlated predictor variables or using techniques like regularization to address it.

t/f if f '(x) = g'(x) for 0 < x < 6, then f(x) = g(x) for 0 < x < 6.
Answers
The statement "if f'(x) = g'(x) for 0 < x < 6, then f(x) = g(x) for 0 < x < 6" is false. This statement is False. If f'(x) = g'(x) for 0 < x < 6, it means that the derivatives of both functions are equal on the interval (0, 6).
However, this does not necessarily mean that the functions themselves are equal on that interval.
In other words, there could be a constant difference between f(x) and g(x), which would not affect their derivatives.
To illustrate this, consider the functions f(x) = x^2 and g(x) = x^2 + 1. The derivative of both functions is 2x, which is equal for all values of x.
However, f(x) and g(x) are not equal on the interval (0, 6), as g(x) is always greater than f(x) by 1.
Therefore, the statement "if f'(x) = g'(x) for 0 < x < 6, then f(x) = g(x) for 0 < x < 6" is false.

In 2022, Skylar sold equipment for $99,800 cash and a $998,000 note due in two years. Skylar's cost of the property was $798,400, and he had deducted depreciation of $479,040.
How much gain can be deferred under the installment sale method?
Answers
So the amount of gain that can be deferred under the installment sale method is $424,879.16.
What is percent?Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred" in Latin. When a number is expressed as a percentage, it is usually accompanied by the "%" symbol. Percentages are commonly used in many areas of everyday life, such as finance, taxes, and statistics. They are often used to express changes or differences, such as percentage increases or decreases in prices or quantities, or the percentage of people who hold a certain opinion or belong to a certain group.
Here,
To calculate the gain that can be deferred under the installment sale method, we need to first calculate the total gain on the sale. The total gain is equal to the selling price minus the adjusted basis of the property, which is the cost minus the accumulated depreciation.
Selling price = $99,800 cash + $998,000 note = $1,097,800
Adjusted basis = $798,400 - $479,040 = $319,360
Total gain = $1,097,800 - $319,360 = $778,440
To calculate the gain that can be deferred, we need to determine the gross profit percentage. The gross profit percentage is equal to the total gain divided by the selling price:
Gross profit percentage = Total gain / Selling price = $778,440 / $1,097,800 ≈ 0.7097 or 70.97%
Now we can calculate the amount of gain that can be deferred using the formula:
Gain deferred = Gross profit percentage × Payments received
Since the note is due in two years, Skylar will receive half of the payments in 2022 and the other half in 2023. Therefore, the payments received in 2022 are:
$99,800 + ($998,000 / 2) = $598,800
Substituting into the formula, we get:
Gain deferred = 0.7097 × $598,800 = $424,879.16
