5.2 .5 Quiz: Global Commerce Before the Columbian Exchange, most people in the New World did not rely on livestock to help them grow food. Which statement from this passage supports this conclusion? American Indians were very, very roughly speaking the equal of Old World farmers of crops. But American Indians were inferior to the Old World raisers of animals. The horse, cattle, sheep, and goat are all of Old World origin. The only American domesticated animals of any kind were the alpaca and the llama. One of the early advantages of the Spanish over the Mexican Aztecs, for instance, was that the Spanish had the horse. It took the American Indians a little while to adopt the horse and become equals on the field of battle.

11) \( x^{3}+75=200 \) 12) \( \sqrt{x-3}=6 \) 13) \( 3 \cdot \sqrt[3]{x}+5=26 \) 14) \( (x+2)^{2}=81 \) 15) \( 3 x^{2}+2=14 \) 16) \( (2 x+1)^{3}=343 \) 17) \( 5 x-2^{2}=\sqrt{36} \) 18) \( 7 x^{2}-3=60 \) 19) \( 3(2 x+3)=5 x+12 \) 10) \( \sqrt{9 \cdot(x+1)}=54: 6 \)

A data set includes systolic blood pressure measurements from 147 adult females. If we compute the values of sample statistics from that sample, which of the following statistics are unbiased estimators of the corresponding population parameters? Select all that apply. \( \square \) A. Sample standard deviation \( \square \) B. Sample proportion

53. Let \( f(x)=3 x^{2}-7 \) and \( (g \circ f)(4)=9 \). Find \( (g \circ f)(-4) \).

Compare your rounded answers to your calculated answers. How far off were they? Explain your reasoning.
