Charlie builds sailboats for a shipyard. He builds various sizes of sailboats such that the speed of the sailboat (with the wind). Ax), in knots, largely depends on the length of the sail, x in feet, and is twice the square root of its length.
Dan also builds sailboats, but for another shipyard. The function gives the relationship between the speed of the sailboat, gfx. in knots, and
length of the sail, x in feet: 5()=152
Function Axlis
Function gx is

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

Astick 2 m long is placed vertically at point b. the top of the stick is in line with the top of a tree as seen from point a, which is 3 m from the stick and 30 m from the tree. how tall is the tree?

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.
