Aquality control engineer is in charge of the manufacture of computer disks. two different processes can be used to manufacture the disks. he suspects that the kohler method produces a greater proportion of defects than the russell method. he samples 150 of the kohler and 200 of the russell disks and finds that 27 and 18 of them, respectively, are defective. if kohler is designated as "group 1" and russell is designated as "group 2," the hypotheses that should be tested are:

Fast! find the length of cu. the triangles are similar. show your work.

Need same math paper but the back now i hope your able to read it cleary i need with hw

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?
