What is the recursive formula of the geometric sequence? 1,5, 25, 125, 625, ...

A) an = (1) · (1/5)^– 1 for n > 1

B) an = (1) · (5)^n - 1 for n > 1

C) a1 = 1; an = an - 1 · (5) for n > 2

D) a1 = 5; an = an- 1 • (1) for n > 2

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
