Lynn, Jude, and Anne were given the function f(x)= -2x^2+32, and they were asked to find f(4). Lynn's answer was 16, Jude's answer was 0, and Anne's answer was ±2. Who is correct?

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

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
