Dilate line f by a scale factor of one half with the center of dilation at the origin to create line f'. Where are points A' and B' located after dilation, and how are lines f and f' related? The locations of A' and B' are A' (0, 2) and B' (0, 0); lines f and f' intersect at point A. The locations of A' and B' are A' (0, 1) and B' (1, 0); lines f and f' are parallel. The locations of A' and B' are A' (0, 0) and B' (2, 0); lines f and f' intersect at point B. The locations of A' and B' are A' (0, 2) and B' (2, 0); lines f and f' are the same line.

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
