An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120120 lb and 161161 lb. the new population of pilots has normally distributed weights with a mean of 129 lb129 lb and a standard deviation of 30.6 lb30.6 lb.

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
