There are 15,750 visitors at the football stadium. One of them is to be selected at random to win a prize. If the probability that a woman will be selected is 2/63, what is the number of women at the stadium?

Explanation

Answer: C - The number of women at the football stadium is 500. A probability of 2/63 means that of every 63 visitors 2 are women. Use a proportion to find the number of women among 15,750 visitors.
2:63=x:15,750
63x=15,750×2
x =(15,750×2)/63=250×2=500

After a peak period of exploration and classification of new species in the 1930s, the discovery of new creatures on the planet dropped significantly and has continued to decline. It is tempting, in light of the decreasing frequency of new identifications, to believe that all of the species in the natural world have been discovered. That, however, is not the case. In fact, in August of 2013, researchers from the Smithsonian’s National Museum of Natural History confirmed the discovery of a new species of mammal, the olinguito. The first indication that a new species might exist was identified in 2003. Kristofer Helgen, the curator of mammals at the museum, was evaluating specimens at a museum in Chicago when he discovered a collection of pelts that he had never seen before. “They were these rich, red skins with flowing fur,” noted Helgen. The data gathered with the skins identified their native locale as the northern Andes Mountains, at elevations higher than those common to the olingo, a related species they somewhat resembled. Spurred on by this discovery, Helgen assembled a team of researchers from the United States and Ecuador and set out to search for the animal in the Otanga Cloud Forest Preserve of Ecuador. The team happened upon the animal their first night in the jungle. Through their work on that first journey and several subsequent trips the team not only confirmed the existence of the new species, but also four subspecies. In their research, the team discovered that a live olinguito actually lived in the United States during the 1960s. The female olinquito was moved from zoo to zoo and refused to mate with olingos. Although the olinguito was only identified recently, it is neither rare nor endangered. Researchers estimate that thousands of the animals inhabit the forests of the preserve. The only major threat is the impact of deforestation on their habit, and even that, to this point, doesn’t seem to have a serious effect. Based on this passage, one can reasonably conclude that:

Let Prosperity Begin With the United States newly formed, citizens were excited about the prosperity that awaited them. The Revolutionary War had ended and the most powerful nation in the land was sure to offer the promise of wealth and financial gain. Unfortunately, with the realization that the Continental Congress, the governing body of the United States, was nearly bankrupt, the reality of fortune began to dissolve into the grim reality of despair. Given the armed mobs that were actively revolting in Massachusetts, the opposition between some states, and the United States’ inability to defend itself, a convention was called together in 1787. At this meeting, the Continental Congress and members from several states met in Philadelphia. The purpose was clear: amendments needed to be added to the Articles of Confederation. It had been noted that the current form of the American Constitution was lacking. Once the meeting began, the result was entirely different than originally anticipated. With more than fifty delegates in attendance from twelve of the thirteen states, proposals for the three branches of government were presented. As discussion continued among the farmers, merchants, lawyers, and Revolutionary War heroes, the legislative, executive, and judicial branches were formed. What followed was the official drafting of the Constitution, which was completed on September 17, 1787. Three years later, on May 29, 1790, the final state, Rhode Island, ratified the Constitution, making it “the supreme law of the land.”Why was the Continental Convention formed?
