.15 is your answer, seeing as .15 is equivalent to 15%
Z score = (x -mean) / standard deviation.
For this problem X = 50 cm.
Z-score = (50 - 49.2) / 1.8
Z score = 0.8 / 1.8
Z score = 0.44
Look up 0.44 on a z-score table.
0.44 = 0.6700
0.67 x 100 = 67% will be 50 cm or longer.
Answer:
26 2/3 mph
Step-by-step explanation:
time = distance/speed
speed = distance/time
Use the first of these relations to find Aidan's time getting to school:
time = 16 mi/(40 mi/h) = 16/40 h = 0.4 h
Then the time Aidan takes to get home is 0.6 hours, and his average speed for that trip home is ...
speed = 16 mi/(0.6 h) = 26 2/3 mi/h
