Suppose a ferris wheel with a 75 foot radius takes 3 minutes to complete 1 rotation. Use π = 3.14 in your calculator and round answers to the hundredths place. Answer the following:
a. After 40 seconds, through how many radians would a rider on the ferris wheel have traveled?
radians
b. How long would it take to travel through 3 radians?
seconds
c. What is the rotational speed of the rider on the ferris wheel in radians per second?
radians/second

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
