You have $47 to spend at the music store. Each cassette tape costs $5 and each CD costs $10. Write a linear inequality that represents this situation. Let x represent the number of tapes and y the number of CDs. 10x + 5y ≥ 47
5x + 10y ≥ 47
5x + 10y ≤ 47
10x + 5y ≤ 47

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
