Select three equations that have no solution. a.19 + b + 12b – 8 – 5b = 2b – 7 + 3b + 3b – 4 b.4b – 9b – 13 – 6 + 16b = 1 – 8 + 6b + 5b – 12 c.7 + 7b – 2 – 15b + b = 4b – 5 – 11b + 2 + 10 d.10b + 8b + 9 – 18b + 3 = 5 + 6b – 2b – 12 + 7 e.9 – 19b – 9 – 2b + 7b = 4b + 3 + 14 – 4b – 17 f.8b – 10 + b + 3b + 2 = 7 + 2b + 10b – 18 – 3

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

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?
