Kristin boards a Ferris wheel at the 3 o'clock position and rides the Ferris wheel for one full rotation as shown. The Ferris wheel's radius is 11 meters long. Let s represent the distance Kristin has traveled along the circular path since the ride started (in meters). Imagine an angle centered at the Ferris wheel's center that subtends the path Kristin travels. Write an expression (in terms of s) to represent the angle's measure (in radians).

At the albinism gene, a population has a 10% frequency of the recessive “a” allele. If you sample two alleles from the population at random, what is the probability that you get an a/a homozygote (i.e., both of the alleles that you sample are “a”)? Assume the population is so large that pulling out the first allele does not alter the allele frequencies. Group of answer choices 80% 1% 10% 20% 19%
