2. the length of a rectangle is 5 mm longer than its width. its perimeter is more than 30 mm. let w equal the width of the rectangle.
(a) write an expression for the length in terms of the width.
(b) use expressions for the length and width to write an inequality for the perimeter, on the basis of the given information.
(c) solve the inequality, clearly indicating the width of the rectangle.

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
