Can someone me? ! 100% sure allison practices the piano for at least 15 hours per week. she practices for three fourths of an hour each session. if allison has already practiced 3 hours this week, how many more sessions remain for her to meet or exceed her weekly practice goal? question 2 options: 16 15 14 13 solve. -p - 4p > -10 question 3 options: p < -2 p > -2 p > -2 p < 2 solve. -3 - 6(4x + 6) ≥ 9 question 4 options: x ≤ -2 x ≤ 2 x ≥ -2 x ≥ 2 find the solution set for the given inequality if the replacement set is {3, 4, 5, 6, 7} 2x - 2 ≥ 10 question 9 options: {3,4,5} {6,7} {7} {6}

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
