To better measure the effects of increases in poaching, the nation of Wakanda began a study in 2000 to track the number of elephants in each of the country's three administrative districts. Every two years, researchers performed a count of the number of elephants in each region; these counts were performed in January. The table above shows the results of the study.

Researchers determine that at a 95% confidence level, their margin of error for the population of elephants in 2010 was 17.4. If the actual population in 2010 is within the confidence interval, what is the lowest possible population of elephants in Wakanda in 2010 ?

  • A. 1317
  • B. 1318
  • C. 1319
  • D. 1320


In figures I and II above, two stacks of identical carpenter's sawhorses are shown, with heights of 92 and 60 inches, respectively. The height, in inches, of a stack of k sawhorses is given by the function h(k) = 16k + 12, where k is a positive integer and k ≥ 1. The number 12 in the function represents which of the dimensions shown in Figure III ?

  • A. a, the height of one sawhorse
  • B. b, the distance from the bottom of one sawhorse to the bottom of the next highest sawhorse
  • C. c, the distance from the top of one sawhorse to the bottom of the next highest sawhorse
  • D. d, the width of a sawhorse at the top


In the figure above, if sin a = cos b, which of the following is closest to the length of DF ?

  • C. 11.2
  • D. 12


Rick, Shane, and Darryl work at a widget factory. The table above shows the number of hours they each spent at the factory on a given day, the number of widgets they produced, and the number of 15-minute breaks they took while they were at the factory. Each man works at a constant rate.

Rick and Shane are each assigned an equal number of widgets. Neither will take breaks in order to complete this assignment as quickly as possible. Rick offers to do a certain percentage of Shane's assignment so that they both finish at the same time. What percentage of Shane's original assignment does Rick do?

  • A. 12.50%
  • B. 14.30%
  • C. 16.70%
  • D. 25%
