Heather paid $2,214.00 for a computer. If the price paid includes a 8% sales tax, which of the following equations can be used to determine the price of the computer after tax?
(Let x represent the cost of the computer and y represent the total cost after tax.)
OA. y = 1.08x
B.
y = 1.8x
OC.
y = x + 8x
D. y = 0.92x

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
