An fruit grower knows from previous experience and careful data analysis that if the fruit on a specific kind of tree is harvested at this time of year, each tree will yield, on average, 130 pounds, and will sell for $5.2 per pound. However, for each additional week the harvest is delayed (up to a point), the yield per tree will increase by 1.7 pounds, while the price per pound will decrease by $0.06. A) How many weeks should the grower wait before harvesting the apples in order to maximize the sales revenue per tree? (Round your answer to the nearest tenth of a week.) (rounded to the nearest tenth) B) Use your answer in part A to find the actual maximum revenue that can be expected. (Round your answer to the nearest dollar.) dollars (rounded to the nearest Answer: Answer: dollar)

5) If you purchase eggplants for $1.39/lb. Then how much will be the eggplant Edible Portion Cost per pound if the yield percent is 76%, and they each weigh in average 1.25 pounds?

2. The average adult spends 7 hours every night sleeping. If it is estimated that 20% of sleep is spent in deep sleep, how much time (in days) are spent in deep sleep each year?

2a. Assume that the world population is 6 billion people and that the birth rate is 2.25% and the death rate is 1.25%. How many years will it take in order for the population to double?

An fruit grower knows from previous experience and careful data analysis that if the fruit on a specific kind of tree is harvested at this time of year, each tree will yield, on average, 127 pounds, and will sell for $4.6 per pound. However, for each additional week the harvest is delayed (up to a point), the yield per tree will increase by 2.1 pounds, while the price per pound will decrease by $0.07.   A) How many weeks should the grower wait before harvesting the apples in order to maximize the sales revenue per tree? (Round your answer to the nearest tenth of a week.)   Answer: __________ (rounded to the nearest tenth)   B) Use your answer in part A to find the actual maximum revenue that can be expected. (Round your answer to the nearest dollar.)   Answer: ____________ dollars (rounded to the nearest dollar)

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 20out of 860fish died when caught and released using barbless hooks on flies or lures. All hooks were removed from the fish.   (a) Let prepresent the proportion of all pike and trout that die (i.e., pis the mortality rate) when caught and released using barbless hooks. Find a point estimate for p. (Round your answer to four decimal places.)(b) Find a 99% confidence interval for p. (Round your answers to three decimal places.) lower limit       upper limit

Given the statement: In 6 trading days, the stock price rose $29.59. How rapidly, on average, has the stock price changed on a daily basis?

In 1997 Fuller and coworkers at Texas A&M University estimated the operating costs of cotton gin plants of various sizes. The operating costs of the next to the smallest plant is shown in the following table. x 2000 4000 6000 8000 10000 12000 y 163,200 230,480 301,500 376,160 454,400 536,400 Here x is the annual number of bales produced, and y is the dollar total cost. (Use 4 decimal places in your answer.)A. Determine the best fitting line using least squares. Also determine the square of the correlation coefficient.The best fitting line is C(x) =         .The square of the correlation coefficient is r2 =         .B. The study noted that revenue was $63.25 per bale. At what level of production will this plant break even?The revenue equation is R(x) =        The profit equation is P(x) =        The production will break even when         bales are produced.C. What are the profits or losses when production is 3000 bales? 4000 bales? (Round to the nearest cent.)When…
