Match the parametric equations with the verbal descriptions of the surfaces by putting the letter of the verbal description to the left of the letter of the parametric equation. d 1. r(u, v)=ui+cosvj+sinvk 2. r(u, v)=ui+vj+(2u−3v)k 3. r(u, v)=ui+ucosvj+usinvk 4. r(u, v)=ucosvi+usinvj+u2k

Which value of c would make he following expression completely factored? 8x+cy

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
