Define g(n): =f( we want to find a closed formula for g(n)g(n). first of all, we want to find a recurrence for g(n)g(n). if nn is odd, then it is pretty easy to see that g(n) = g(n-1)g(n)=g(n−1). if nn is even, try to write g(n)g(n) in terms of g(n/2)g(n/2).

Find the equation of the trend line (line of best fit). show your work i'm using the points (34,76) (42,91)

Which simplifys to a+ b? a-(1-b)+1 -(1-a)-b+1 (a--1) -1)+1

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.
