The amount of milk sold each day by a grocery store varies according to the normal distribution with a mean of 130 gallons and a standard deviation of 12 gallons. On a randomly selected day, the probability that the store sells at least 154 gallons is what ?

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

answer: i ! the answer is   9000 seconds, also d

hope i

-lavira : )

16 is the coefficient

hope this
