If the Hubble constant is 70 km/s/max, how far away is the quasar that has an apparent recession of 45,000 km/s? Use the Hubble law v=h0d where v= velocity of galaxy, in km/s, h0=Hubble constant, measured in km/s/mpc, d= distance of galaxy, in mpc, what percentage of light is this? (It’s the first question in the Picture)

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.
