Samples of 20 parts from a metal punching process are selected every hour. typically, 1% of the parts require rework. let x denote the number of parts in the sample of 20 that require rework. a process problem is suspected if x exceeds its mean by more than 3 standard deviations. (a) if the percentage of parts that require rework remains at 1%, what is the probability that x exceeds its mean by more than 3 standard deviations? (b) if the rework percentage increases to 4%, what is the probability that x exceeds 1? (c) if the rework percentage increases to 4%, what is the probability that x exceeds 1 in at least one of the next five hours of samples?

Me! i'm really confused the isosceles trapezoids, abcd and efgh, are similar quadrilaterals. the scale factor between the trapezoids is 2: 3, line gh = 6 centimeters, line ad = 8 centimeters, and line ab is three times the length of line dc . use complete sentences to answer the following prompts and include all of your calculations in your final answer. a. write a similarity statement for each of the four pair of corresponding sides. b. write a congruence statement for each of the four pair of corresponding angles. c. determine the perimeter for each of the isosceles trapezoids.
