- = Question 4 (5pt): The Orchard Problem. Below is the graph y f(t) of the annual harvest (assumed continuous) in kg/year from my cranapple orchard t years after planting. The trees take about 25 years to get established, and from that point on, for the next 25 years, they give a fairly good yield. But after 50 years, age and disease are taking their toll, and the annual yield is falling off. 40 35 30 。 ៣៩ ថា8 8 8 8 6 25 20 15 10 y 5 0 0 5 10 15 20 25 30 35 40 45 50 55 60 The orchard problem is this: when should the orchard be cut down and re- planted, thus starting the cycle again? What you want to do is to maximize your average harvest per year over a full cycle. Of course there are costs to cutting the orchard down and replanting, but it turns out that we can ignore these. The first cost is the time it takes to cut the trees down and replant but we assume that this can effectively be done in a week, and the loss of time is negligible. Secondly there is the cost of the labour to cut…arrow_forwardWrite the prime factorization of 8. Use exponents when appropriate and order the factors from least to greatest (for example, 22.3.5).

- Clint is building a wooden swing set for his children. Each supporting end of the swing set is to be an A-frame constructed with two 10 foot long 4-by-4s joined at a 45 degree angle. To prevent the swing set form tipping over, Clint wants to secure the base of each A-frame to concrete footings. How far apart should the footings for each A-frame be?arrow_forwardA hat contains slips of paper numbered 1 through 6.

- In addition to the in-school milk supplement program, the nurse would like to increase the use of daily vitamin supplements for the children by visiting homes and educating about the merits of vitamins. She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference? Assume that drop-out rate is 5%.arrow_forwardA recent survey of 400 americans asked whether or not parents do too much for their young adult children.
