Andrew and Matthew discuss divisibility. Andrew says, “280 is divisible by 5 and by 8.
5 × 8 = 40, so 280 is also divisible by 40.”
Matthew says, “296 is divisible by 4 and by 8.
4 × 8 = 32, so 296 is also divisible by 32.”
Are both Andrew and Matthew correct?
Explain your thinking.

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?
