Explanation Given: The differential equation x 2 y ' ' − x y ' + y = 2 x . It can be written as x 2 d 2 y d x 2 − x d y d x + y = 2 x . Since the equation is nonhomogeneous, first solve the associated homogeneous equation. Calculations: Assume y = x m be a solution of the homogeneous differential equation. Differentiating twice d y d x = m x m − 1 , d 2 y d x 2 = m ( m − 1 ) x m − 2 Substitute y and d 2 y d x 2 into the differential equation yields: x 2 . m ( m − 1 ) x m − 2 − x m x m − 1 + x m = 0 ( m 2 − 2 m + 1 ) x m = 0 Solving the auxiliary equation ( m − 1 ) ( m − 1 ) = 0 ,we get m = 1 with multiplicity 2. The complementary solutions is y c = c 1 x + c 2 x ln x . x 2 y ' ' − x y ' + y = 2 x y ' ' − x − 1 y ' + x − 2 y = 2 x − 1 y ' ' − x − 1 y ' + x − 2 y = 2 x − 1 Here f ( x ) = 2 x − 1

You have been hired as an intern to run analyses on the data and report the results back to Sarah; the five questions that Sarah needs you to address are given below. Does there appear to be a positive or negative relationship between price and screen size? Use a scatter plot to examine the relationship. Determine and interpret the correlation coefficient between the two variables. In your interpretation, discuss the direction of the relationship (positive, negative, or zero relationship). Also discuss the strength of the relationship. Estimate the relationship between screen size and price using a simple linear regression model and interpret the estimated coefficients. (In your interpretation, tell the dollar amount by which price will change for each unit of increase in screen size). Include the manufacturer dummy variable (Samsung=1, 0 otherwise) and estimate the relationship between screen size, price and manufacturer dummy as a multiple linear regression model. Interpret the…
