Anna created the poster shown below: What would be the dimensions of the poster at fraction 1 over 4 times its current size? A.) Length = 9 cm, width = 4 cm
B.) Length = 144 cm, width = 64 cm
C.) Length = 32 cm, width = 12 cm
D.) Length = 40 cm, width = 20 cm

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.

What function has a range {yly< 5}? question on picture above^

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
