Astate highway that is 4^4 miles long runs parallel to a smaller country road that is 4^2 miles long. how many times longer than the country road is the state highway? write the answer as a number with a positive exponent.

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

I'm confused on this could anyone me and show me what i need to do to solve it.

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.
