The equation of the least squares regression line is modifyingabove y with caret equals 2.0233 x minus 2.3256 and the sum of squared residuals for this line is 0.7907. answer parts (). x 3 4 5 7 8 y 4 6 7 12 14 (a) predict the mean value of y if xequals12. modifyingabove y with caret equals 22 (round to one decimal place as needed.) (b) construct a 95% confidence interval about the mean value of y if xequals12.

step-by-step explanation:

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

yes
