A botanist has developed a new hybrid cotton plant that can withstand insects better than other cotton plants. However, there is some concern about the germination of seeds from the new plant. To estimate the probability that a seed from the new plant will germinate, a random sample of 3000 seeds was planted in warm, moist soil. Of these seeds, 2430 germinated. Either a seed germinates or it does not. What is the sample space in this problem? Do the probabilities assigned to the sample space add up to 1? Should they add up to 1? Explain.

The following questions are unrelated except that they all apply to plant assets and intangible assets:

1. The manager of Wallace Manufacturing regularly buys plant assets and debits the cost to Repairs and Maintenance Expenses. Why would she do that, since she knows this action violates GAAP?
2. The manager of Arbor Homes debits the cost of repairs and maintenance of plant assets to Plant and Equipment. Why would he do that, since he knows he is violating GAAP?
3. It has been suggested that because many intangible assets have no value except to the company that owns them, they should be valued at $1.00 or zero on the balance sheet. Many accountants disagree with this view. Which view do you support? Why?

Scrap rates per thousand (parts whose defects cannot be reworked) are compared for 5 randomly selected days at three plants. Does the data show a significant difference in mean scrap rates?

You are handed a mystery pea plant with tall stems and axial flowers and asked to determine its genotype as quickly as possible. You know that the allele for tall stems (7) is dominant to that for dwarf stems (t) and that the allele for axial flowers (A) is dominant to that for terminal flowers (a). Identify ALL the possible genotypes for your mystery plant.

The part of a plant embryo that feeds the growing seedling is the A. seed coat. B. primary root. C. endosperm. D. cotyledon.

A farmer has three hundred acres of arable land on which she wants to plant cauliflower and cabbage. The farmer has $\$ 17,500$ available for planting and $\$ 12,000$ for fertilizer. Planting 1 acre of cauliflower costs $\$ 70$, and planting 1 acre of cabbage costs $\$ 35$. Fertilizer costs $\$ 25$ for 1 acre of cauliflower and $\$ 55$ for 1 acre of cabbage.

(a) Find a system of inequalities that describes the number of acres of each crop that the farmer can plant with the available resources. Graph the feasible region.

(b) Can the farmer plant one hundred fifty-five acres of cauliflower and one hundred fifteen acres of cabbage?

(c) Can the farmer plant one hundred fifteen acres of cauliflower and one hundred seventy-five acres of cabbage?

t has been reported that the average life for halogen lightbulbs is 4000 hours. Learning of this figure, a plant manager would like to find out whether the vibration and temperature conditions that the facility's bulbs encounter might be having an adverse effect on the service life of bulbs in her plant. In a test involving 15 halogen bulbs installed in various locations around the plant, she finds the average life for bulbs in the sample is 3882 hours, with a standard deviation of 200 hours. Assuming the population of halogen bulb lifetimes to be approximately normally distributed, and using the $0.025$ level of significance, do the test results tend to support the manager's suspicion that adverse conditions might be detrimental to the operating lifespan of halogen lightbulbs used in her plant?

What are stewardship assets? How does the accounting for a stewardship asset differ from that for general property, plant, and equipment?

Plants that thrive in salt water must have internal solutions (inside the plant cells) that are isotonic with (have the same osmotic pressure as) the surrounding solution. A leaf of a saltwater plant is able to thrive in an aqueous salt solution (at $\left.25^{\circ} \mathrm{C}\right)$ that has a freezing point equal to $-0.621^{\circ} \mathrm{C} .$ You would like to use this information to calculate the osmotic pressure of the solution in the cell. Solve for the osmotic pressure (at $\left.25^{\circ} \mathrm{C}\right)$ of the solution in the plant cell.

A power plant has a power output of 1055 MW and operates with an efficiency of 0.330. Excess energy is carried away as heat from the plant to a nearby river. How much energy is transferred away from the power plant as heat? A. $0.348 \times 10^{9} \mathrm{J} / \mathrm{s}$, B. $0.520 \times 10^{9} \mathrm{J} / \mathrm{s}$, C. $0.707 \times 10^{9} \mathrm{J} / \mathrm{s}$, D. $2.14 \times 10^{9} \mathrm{J} / \mathrm{s}$.

PhotoTech, Inc., a manufacturer of rechargeable batteries for digital cameras, signed a contract with a digital photography company to produce three models of lithium-ion battery packs for a new line of digital cameras. The contract calls for the following:

$$\begin{array}{cc} \text { Battery Pack } & \text { Production Quantity } \\ \text { PT-100 } & 200,000 \\ \text { PT-200 } & 100,000 \\ \text { PT-300 } & 150,000 \end{array}$$

PhotoTech can manufacture the battery packs at manufacturing plants located in the Philippines and Mexico. The unit cost of the battery packs differs at the two plants because of differences in production equipment and wage rates. The unit costs for each battery pack at each manufacturing plant are as follows:

$$\begin{array}{ccc} \text { Product } & \text { Philippines } & \text { Mexico } \\ \text { PT-100 } & \$ 0.95 & \$ 0.98 \\ \text { PT-200 } & \$ 0.98 & \$ 1.06 \\ \text { PT-300 } & \$ 1.34 & \$ 1.15 \end{array}$$

The PT-100 and PT-200 battery packs are produced using similar production equipment available at both plants. However, each plant has a limited capacity for the total number of PT-100 and PT-200 battery packs produced. The combined PT-100 and PT-200 production capacities are 175,000 units at the Philippines plant and 160,000 units at the Mexico plant. The PT-300 production capacities are 75,000 units at the Philippines plant and 100,000 units at the Mexico plant. The cost of shipping from the Philippines plant is $0.18 per unit, and the cost of shipping from the Mexico plant is$0.10 per unit.

a. Develop a linear program that PhotoTech can use to determine how many units of each battery pack to produce at each plant to minimize the total production and shipping cost associated with the new contract.

Define variables and write a system of equations for the situation. Solve using substitution. A farmer grows only sunflowers and flax on his 240-acre farm. This year he wants to plant 80 more acres of sunflowers than of flax. How many acres of each crop does the farmer need to plant?

Ford has four automobile plants. Each is capable of producing the Taurus, Lincoln, or Escort, but it can only produce one of these cars. The fixed cost of operating each plant for a year and the variable cost of producing a car of each type at each plant are given in Table 51. Ford faces the following restrictions: a. Each plant can produce only one type of car. b. The total production of each type of car must be at a single plant; that is, for example, if any Tauruses are made at plant 1, then all Tauruses must be made there. c. If plants 3 and 4 are used, then plant 1 must also be used. Each year, Ford must produce 500,000 of each type of car. Formulate an IP whose solution will tell Ford how to minimize the annual cost of producing cars. TABLE 51:

$$\begin{matrix} \text{Plant} & \text{Fixed Cost (\$)} & \text{Variable Cost (\$)}\\ \text{ } & \text{ } & \text{Taurus} & \text{Lincoln} & \text{Escort}\\ \text{1} & \text{7 billion} & \text{12,000} & \text{16,000} & \text{9,000}\\ \text{2} & \text{6 billion} & \text{15,000} & \text{18,000} & \text{11,000}\\ \text{3} & \text{4 billion} & \text{17,000} & \text{19,000} & \text{12,000}\\ \text{4} & \text{2 billion} & \text{19,000} & \text{22,000} & \text{14,000}\\ \end{matrix}$$
