The authors of this study (Porter, Guzdial, McDowell, & Simon, 2013) state "Assuming that the pass rate found in this survey is representative, approximately 650,000 students every year do not pass CS1.
The collection includes nearly 3,000 specimens of about 300 fish species and more than 3,500 representatives of approximately 150 different kinds of invertebrates.
Nuclear receptors belong to the best-characterized representatives of approximately 3,000 different mammalian proteins that are involved in transcriptional regulation in human tissues [9].
An optimized design for the network was determined to be a minimum of 21 sites in a representative and approximately uniform geographic distribution.
A representative area approximately 4 km2 in extent located within The Burren National Park was studied in order to determine the distributions of soil types and relate these to geology, glacial erosion and deposition, post-glacial mass movements and land use.
Two hundred and twenty-two members of ARCSA responded to the survey; the responses were representative of approximately 2700 RWH systems across the United States that the respondents own, have installed, or have observed in the field.
Individual pixels, representative of approximately 3 square kilometers, were assigned a number based on their degree of illumination, ranging from 0 (complete darkness) to 63 (brightly lit urban areas).
F− dose in rodents of 100 ppm is, therefore, representative of approximately 10 ppm in humans.
The experiments were performed in triplicate, and each figure is the representative of approximately 15 20 images.
The G9a null embryos do not develop beyond the 5 6 somite stage, representative of approximately day 8.25, though they survive until day 9.5 when they begin to die.
