There are a couple of questions, I'd really appreciate your help. (1) It takes 16 minutes to set up a candy making machine. Once the machine is set up, it produces 15 candies per minute. Use an inequality to find the number of candies that can be produced in 5 hours if the machine has not yet been set up. A: 75 candies (2) 8+|1-(x/2)|?10 A: (-?, -2] U [6, ?) (3) 6(x + 2) ? 5(x - 1) + x A: NO SOLUTION (4) -5x + 1 ? 11 or 3x + 3 ? -9 A: (-?, ?) (5) A random survey of 4000 TV households in the U.K. yielded the following data on the viewing percentages of five television programs in a given week. Let x represent the actual viewing percentage in the U.K. population. If the margin of error is 3%, find the percentage of the viewing public that watched Union Street (11.8%) last week. Express the answer in set-builder notation. A: { x| 8.8?X?148 } (NOT SURE ABOUT THIS) (6) -29 ? -4x - 1 < -13 A: (3, 7] (7) -9x + 4 - 7x < 10 - 18x + 10 A: (-?, 8) (8) -5x > -25 and x + 5 > 6 A: (1, 5) (9) |5x + 3| + 3 = 11 A: {1, -(11/3)} (10) (x-1)/18 ? (x-1)/24+(1/72) A: [2, ?) (11) The radius r of a plastic tube used in manufacturing a child's toy must not differ from the standard s by more than 5 millimeters. The manufacturing engineers express this as If the standard s is 23, solve the inequality for the radius r. Express the answer in set-builder notation. A: {r| 18 ?r ? 28} (12) |3(x+1)+9|?12
