A swimming pool has dimensions of 10 feet by 14 feet by 5 feet. The calculations of five students are shown below. Adina: 70(5) = 350 ft3 Isaac: 14(5)(10) = 700 ft3 Mateo: 10(14) = 140 ft3 Shira: 14(5)(5) = 350 ft3 Zamir: 10(14)(5) = 700 ft3 Which students correctly calculated the volume? Check all that apply. Adina Isaac Mateo Shira Zamir

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
