Solution Steps

Step 1: Understanding Terpenes

Terpenes are a large and diverse class of organic compounds produced by a variety of plants, particularly conifers. They are often strong-smelling and may protect the plants that produce them by deterring herbivores and by attracting predators and parasites of herbivores. Terpenes are hydrocarbons and are classified by the number of isoprene units they contain. The basic molecular formula for terpenes is (C5H8)n.

Step 2: Identifying Isoprene Units

An isoprene unit has the molecular formula C5H8. To identify a terpene, we need to look for structures that are multiples of this unit.

Step 3: Analyzing Each Structure
  • Structure I: This structure has 10 carbon atoms and 16 hydrogen atoms (C10H16), which is a multiple of C5H8 (2 isoprene units).
  • Structure II: This structure has 10 carbon atoms and 16 hydrogen atoms (C10H16), which is a multiple of C5H8 (2 isoprene units).
  • Structure III: This structure has 8 carbon atoms and 12 hydrogen atoms (C8H12), which is not a multiple of C5H8.
  • Structure IV: This structure has 10 carbon atoms and 16 hydrogen atoms (C10H16), which is a multiple of C5H8 (2 isoprene units).

Final Answer

The structures that are terpenes are I, II, and IV. However, since the question asks for which one is a terpene, we can select any one of these.

Freight car loadings over an 18-week period at a busy port are as follows: Week Number 1 300 2 305 3 310 4 305 5 310 6 315 7 365 8 395 9 425 10 420 11 450 12 480 13 485 14 490 15 540 16 545 17 550 18 555 a. Determine a linear trend line for expected freight car loadings. Note: Round your intermediate calculations and final answers to 2 decimal places. b. Use the above trend equation to predict expected loadings for Weeks 20 21. Note: Round your final answers to 2 decimal places. The forecasted demand for Week 20 is and for Week 21 is c. The manager intends to install new equipment when the volume exceeds 880 loadings per week. Assuming the current trend continues, in which week (at the earliest) should the loading volume reach that level? Note: Use the rounded answers, as required, from any previous part of this problem. Do not round any other intermediate calculations. Round your final answer to 2 decimal places. It should reach 880 loadings in Week

The following data was collected to explore how a student's age and GPA affect the number of parking tickets they receive in a given year. The dependent variable is the number of parking tickets, the first independent variable (x1) is the student's age, and the second independent variable (x2) is the student's GPA. Effects on Number of Parking Tickets Age GPA Number of Tickets --------- 18 2 1 19 3 2 20 3 3 20 3 3 20 3 4 21 3 6 22 3 6 22 3 7 23 3 8 Determine if a statistically significant linear relationship exists between the independent and dependent variables at the 0.05 level of significance. If the relationship is statistically significant identify the multiple regression equation that best fits the data, rounding the answers to three decimal places. Otherwise indicate that there is not enough evidence to show that the relationship is statistically so significant.
