Part III. Determine the sample size given the population (N) and the margin of error (e). by using Slovin’s Formula. 16. N = 1,000 e = 3% 17. N = 3,000 e = 4% 18. N = 12,000 e = 5% 19. N = 60,000 e = 6% 20. N = 100,000 e = 8% 21. N = 250,000 e = 10%

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
