C&A takes 100 samples of 50 units each for inspection. The total number of defects is found to be 75 units. What is the center line of a 3-sigma p-chart?

Trapezoid tuvw is shown on the coordinate plane below: trapezoid tuvw on the coordinate plane with ordered pairs at t 4, 6, at u 7, 6, at v 7, 3, at w 2, 3. if trapezoid t'u'v'w' represents trapezoid tuvw reflected over the y-axis, the ordered pair of w' is (note: you must include parentheses, a comma, and a space after the comma when typing the ordered pair.)
