Hanna says you cannot represent the fraction One-fourth on the number line. A number line going from 0 to 1 with 8 equal spaces between 0 and 1.

Which statement best explains Hanna’s thinking?
Hanna is correct. The space between consecutive integers is divided into eight parts and not four. You cannot represent One-fourth on the line.
Hanna is correct. The number line stops at 1, and you need to be able to have 4 on the graph to graph One-fourth.
Hanna is not correct. You can graph One-fourth if you extend the number line to 4.
Hanna is not correct. The fraction One-fourth is equal to 2/8, so you can graph it on the second tick mark to the right of zero.

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
