A classmate states that if s = {(3, 1), (2, 1), (4, 3), (5, 4)}, then the inverse of s = {(1, 3), (2, 1), (3, 4), (4, 5)} and is also a function. Which is the classmate's error? A. The classmate correctly identified the inverse of s but it is not a function. B. The classmate did not reverse the coordinates of (2, 1), so the inverse of s is wrong but it is still a function. C. The classmate did not reverse the coordinates of (2, 1), so the inverse of s is wrong and it is not a function. D. The classmate should not have reversed any of the coordinates, but the inverse of s is still a function.

Use the normal approximation to the binomial distribution to answer this question. fifteen percent of all students at a large university are absent on mondays. if a random sample of 12 names is called on a monday, what is the probability that four students are absent?

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
