Determine whether the solution space of the system $Ax = 0$ is a line through the origin, a plane through the origin, or the origin only. If it is a plane, find an equation for it. If it is a line, find parametric equations for it, using $t$ as parameter. (a) $A = \begin{bmatrix} -1 & 1 & 1 \\ 2 & 4 & 0 \\ -1 & -5 & -1 \end{bmatrix}$ The solution space is a line through the origin $x = -\frac{2}{3}t$ $y = -\frac{t}{3}$ $z = t$ (b) $A = \begin{bmatrix} 1 & 2 & 3 \\ 6 & 7 & 3 \\ 1 & 0 & 5 \end{bmatrix}$ The solution space is the origin

Question 4 2 pts A student wants to estimate the percent of all Bay Area families having more than 2 children. The student gathers random sample data from 100 families and computed the 95% confidence interval to be (0.153, 0.234). What would be an interpretation of the CI? none of these above 95% of all Bay Area families having more than 2 children We are confident that the percent of all Bay Area family having more than 2 children is between 15.3% and 23.4%. We are 95% confident that the percent of all Bay Area family having more than 2 children is between 15.3% and 23.4%. 95 Bay Area families having more than 2 children
