Bianca has $800 in her checking account. She wants to spend part of this money on a new phone. She wants to have at least $550 in her checking account after
buying the phone. The inequality shown can be used to find m, the amount of money
in dollars that Blanca can spend on the phone.
m + 550 S 800
Which inequality represents all possible values of m?
F. ms 250
G. ms 1,250
H. m 2 250
J. m 2 1,250

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
