Percy wants to use rigid transformations to show that triangle GHI is congruent to triangle LKJ as a way of confirming the SSS triangle congruence criterion. She starts by translating triangle GHI along a vector that Option #1: Percy did not make a mistake. The fact that the triangles do not overlap means that the triangles must not be congruent. Option #2: Percy made a mistake and did not reflect over the correct line segment. She should have reflected triangle G'H'I' across vector GH when creating triangle G"H"I". Option #3: Percy made a mistake and did not match corresponding points correctly. She should have translated triangle GHI along a vector that takes point G to point L when creating triangle G'H'I'.

Some college campuses have started using "puppy therapy" to help reduce stress among students, according to a Psychology Today article. Suppose you design an experiment to test the hypothesis that puppy therapy is an effective stress reducer for students, within the context of a 6-section introductory biology course at your school. Each section has 12 students. Students in three of the sections get to play together with a pack of therapy dogs for 15 minutes at the beginning of the section recitation (or "lab") meeting. The other three sections simply observe 15 minutes of quiet free time instead. Students rate their stress levels immediately after the 15-minute period. Then you measure the percentage of students that report being "very stressed out" for each section, and you compare the average percentage between sections that played with puppies and those that didn't. In your puppy therapy experiment, what is the experimental unit? - A single student - A section in the course - The entire course Check Answer In your puppy therapy experiment, how many replicates are in the experimental group?

22.core.learn.edgenuity.com Sugar Changed the World, Part 4: Building Claims Assignment Active Analyzing Historical Details to Support a Claim In 1806, the antislavery forces brought a new bill before Parliament that would limit British involvement in the slave trade. Some of the most powerful testimony in favor of the bill came from former army officers who had been to the Caribbean and had seen the courage of the former slaves and the horrors of slavery. The slaves spoke through the testimony of the very men who had gone to fight them. One member of Parliament told his colleagues of the tortures he had seen in the islands. Slavery was not an abstraction, an economic force, a counter in the game of world politics-it was the suffering of men and women Members of Parliament were being confronted with the reality of slavery, just as audiences at Clarkson's lectures were when he showed shackles and whips. While Parliament debated the new bill, Clarkson and his allies went on lecturing, talking, changing minds all across England. They succeeded. Newspapers reported that even in Bristol, a port city with a harbor filled with How does this passage support the claim that the sugar trade led to the end of slavery in some parts of the world? It emphasizes that Parliament was biased toward plantation owners and wrongfully supported them. It shows that the French followed the example of the English in overthrowing the crown to free enslaved people. It describes how testimony on the brutal practices on sugar plantations convinced Parliament to end the slave trade. It demonstrates that neither Britain nor France wanted to make changes in the practice of slavery until America did. Intro Done

Sugar Changed the World, Part 4: Building Claims Assignment Active Citing Evidence to Support a Claim The English public, now consuming some eighteen pounds of sugar a year, knew little about the lives of the enslaved Africans whose labor sweetened their meals. Worse yet, every Englishman who hammered the wood, sewed the sails, manufactured the rope for slave ships, or built the barrels to hold slave-harvested sugar made his money from the slave trade. The English were getting richer because Africans were being turned into property. Clarkson and others who believed as he did, who in the coming decades would be called abolitionists, realized that while that link gave the English a stake in slavery, it also gave the antislavery forces an opportunity. If they could reverse the flow-make the horrors of slavery visible to those who benefited from it-they might be able to end the vile practice forever. -Sugar Changed the World, Marc Aronson and Marina Budhos Which quotation provides evidence to support the claim that the sugar trade led to the end of slavery? "The English public . . . knew little about the lives of the enslaved Africans whose labor sweetened their meals." "Every Englishman who . . . built the barrels to hold slave-harvested sugar made his money from the slave trade." "The English were getting richer because Africans were being turned into property."
