24. Match each statement with the algebraic expression that models it. A. The price of a winter coat and a 20% discount B. The base salary of an employee and a 2% salary increase C. The cost of groceries and a 2% discount with coupons D. The number of students attending school last year and a 20% increase from last year x + 0.02x = 1.02x x - 0.20x = 0.80x x + 0.20x = 1.20x x - 0.02x = 0.98x

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
