If f(x) is the slope of a trail at a distance of x miles from the start of the trail, what does 9 f(x)dx 3 represent? The change in the elevation between x = 3 miles and x = 9 miles from the start of the trail. The elevation at x = 9 miles from the start of the trail. The elevation at x = 9 miles from the end of the trail. The change in the elevation between x = 3 miles and x = 9 miles from the end of the trail. The elevation at x = 3 miles from the start of the trail.

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
