1. a 10-foot ladder placed on level ground leans against the side of a house. the ladder reaches a point that is 9.2 feet up on the side of the house. what is the measure of the angle formed by the ladder and the level ground? round your answer to the nearest degree. show your work. 2. the occupational safety and health administration (osha) sets standards for a variety of occupations to prevent accidents and other safety hazards. osha’s standard for the angle formed by a ladder and level ground is. the same 10-foot long ladder is placed against the building according to osha’s safety standard. what is the distance between the foot of the ladder and the foot of the building? round your answer to the nearest tenth. show your work.

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.
