The scales must measure a standardized 2-pound weight at exactly 2 pounds with accuracy within 0.017 pound. (a) Write the possible measured scale weights (in lb) using plus/minus notation. Ib # (b) Write the possible measured scale weights (in lb) using interval notation. (Simplify your answer completely.) (c) All of the measured scale weights must be between which two values (in lb)? All of the measured scale weights must be between a lower value of Ib and an upper value of |lb.11. [-/1 Points] DETAILS DAVISPRESTAT1 3.2.046. MY NOTES ASK YOUR TEACHER Consider the interval. (-5.6, 0.03) Rewrite the interval using plus/minus notation. Determine whether the number zero is contained in the interval. O Yes, zero is contained in the interval. O No, zero is not contained in the interval. Submit Answer 12. [-/1 Points] DETAILS DAVISPRESTAT1 1.5.030. MY NOTES ASK YOUR TEACHER A snack bag of potato chips is advertised as weighing 1.5 ounces. Suppose a bag of potato chips is selected at random from a snack pack and weighs 1.526 ounces. (a) Compute the absolute error. (Simplify your answer completely.) AE = Interpret the result. The advertised weight was off by this much relative to the random sample's weight. O This is the average weight of a single potato chip. The advertised weight was this many ounces off of the random sample's weight. O The advertised weight has this much percent error with the random sample's weight. The advertised weight is incorrect this proportion of the time. (b) Compute the relative error. Round to three decimal places. (Simplify your answer completely.) RE = Interpret the result. O The advertised weight was off by this much relative to the random sample's weight. O This is the average weight of a single potato chip. O The advertised weight was this many ounces off of the random sample's weight. The advertised weight has this much percent error with the random sample's weight. The advertised weight is incorrect this proportion of the time. 13. [-/3 Points] DETAILS DAVISPRESTAT1 3.2.042. MY NOTES ASK YOUR TEACHER
