Findstep-by-step Statistics solutions and your answer to the following textbook question: Researchers wondered whether the trees in a longleaf pine forest in Georgia are randomly distributed. To find out, they divided the forest into four equal quadrants. Then the researchers took a random sample of 100 trees and counted the number in each quadrant.
Givenco-ordinates (x, y), determine the quadrant of the cartesian plane. Input : x = 1, y = 1 Output : lies in 1st quadrant Input : x = 0, y = 0 Output : lies at origin. There are 9 conditions that needs to be checked to determine where does the points lies -. If in first quadrant then, x > 0 and y > 0 If in second quadrant then, x < 0 and ySoit lies in the 1st quadrant. (ii) In the point (− 2, 1) abscissa is negative and ordinate is positive. So it lies in the second quadrant. (iii) In the point (− 1, − 3) abscissa and ordinate are both negative. So it lies in third quadrant. (iv) In the point (5, − 1) abscissa is positive and ordinate is negative. So it lies in the . 8 156 491 50 352 5 378 455
