Marvin was completing the square, and his work is shown below. identify the line where he made his mistake. f(x) = 2x2 − 8x + 5 line 1: f(x) = 2(x2 − 8x) + 5 line 2: f(x) = 2(x2 − 8x + 16) + 5 − 32 line 3: f(x) = 2(x − 4)2 − 27 line 1 line 2 line 3 he did not make any mistakes

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
