The distance it takes a truck to stop can be modeled by the function

Determine the value off, rounded to the nearest

hundredth.

DONE

d(u)=2.1502

64.4f

d = stopping distance in feet

v=nial velocity in miles per hour

= a constant related to friction

When the truck's initial velocity on dry pavement is

40 moh its stopping distance is 138 ft

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
