Determine whether each statement is true or false. if a statement is true, give a reason or cite an appropriate statement from the text. if a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text. (a) adding a multiple of one column of a square matrix to another column changes only the sign of the determinant true, adding a multiple of one column to another changes only the sign of the determinant. false, adding a multiple of one column to another changes the sign of the determinant. false, adding a multiple of one column to another changes the value of the determinant by the multiple of the minor. false, adding a multiple of one column to another does not change the value of the determinant. (b) two matrices are column-equivalent when one matrix can be obtained by performing elementary column operations on the other. false, row-equivalent matrices are matrices that can be obtained from each other by performing elementary row operations on the other. false, row-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other. true, column-equivalent matrices are matrices that can be obtained from each other by performing elementary column operations on the other. true, column-equivalent matrices are matrices that can be obtained from each other by performing elementary row operations on the other. (c) if one row of a square matrix is a multiple of another row, then the determinant is 0. true, you can achieve a row of all zero's by adding a multiple of one row to another which does not change the determinant of the matrix. false, this is true for columns, because you can achieve a column of all zero's by adding a multiple of one column to another which does not change the determinant of the matrix. false, this is true for columns, because you can achieve a row of all zero's by adding a multiple of one row to another which does not change the determinant of the matrix. false, you can achieve a row of all zero's by adding a multiple of one row to another which changes the determinant of the matrix.

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
