Suppose that the life expectancy of a certain brand of nondefective light bulbs is normally distributed, with a mean life of 1900 hr and a standard deviation of 100 hr. if 40 comma 000 of these bulbs are produced, how many can be expected to last at least 1900 hr?

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.
