Solve the following linear systems of differential equations.

Use the following linear regression equation to answer the questions. x3 = -18.8 + 4.0x, + 9.3x4 - 1.3x7 (a) Which variable is the response variable? Which variables are the explanatory variables? (b) Which number is the constant term? List the coefficients with their corresponding explanatory variables. (c) If X1 X3? = 10, X4 = -4, and x7 = 4, what is the predicted value for (d) Explain how each coefficient can be thought of as a "slope" under certain conditions. Suppose x1 and X7 were held at fixed but arbitrary values. If x4 increased by 1 unit, what would we expect the corresponding change in x3 to be? If x4 increased by 3 units, what would be the corresponding expected change in x3? If x4 decreased by 2 units, what would we expect for the corresponding change in x3? (e) Suppose that n = 11 data points were used to construct the given regression equation and that the standard error for the is 0.857. Construct a 90% confidence coefficient of X4 interval for the coefficient of x4.…

Use the following linear regression equation to answer the questions. x1 = 1.5 + 3.6x2 – 7.8x3 + 1.8x4(a) Which variable is the response variable? answer: x1 Which variables are the explanatory variables? (Select all that apply.) answer: x4x3x2 (b) Which number is the constant term? List the coefficients with their corresponding explanatory variables. constant 1.5 x2 coefficient 3.6 x3 coefficient -7.8 x4 coefficient 1.8 (c) If x2 = 10, x3 = 7, and x4 = 7, what is the predicted value for x1? (Use 1 decimal place.) answer: -4.5 (d) Explain how each coefficient can be thought of as a "slope" under certain conditions. answer: If we hold all other explanatory variables as fixed constants, then we can look at one coefficient as a "slope." Suppose x3 and x4 were held at fixed but arbitrary values and x2 increased by 1 unit. What would be the corresponding change in x1? answer: 3.6 Suppose x2 increased by 2 units. What would be the expected change in x1? answer: 7.2 Suppose…

Data on alcohol content and wine quality was collected from variants of a particular wine. From a sample of 50 ​wines, a model was created using the percentages of alcohol to predict wine quality. The data are modeled by Yi=−0.384+0.5332Xi​, where Xi is the alcohol content​ (%) and Yi is the rated quality of the wine. For these​ data, SYX=0.9431​, X=10.19​, and hi=0.029612 when X=11.   a. Construct a 90​% confidence interval estimate of the mean wine quality rating for all wines that have 11​% alcohol.   _____≤μY|X=11≤_______ ​(Type integers or decimals. Round to three decimal places as needed. Use ascending​ order.)
