Steel rods are manufactured with a mean length of 20 centimeter (cm). because of variability in the manufacturing process, the lengths of the rods are approximately normally distributed with a standard deviation of 0.07cm(a)? what proportion of rods has a length less than 19. to four decimal places as )? any rods that are shorter than 19.83 cm or longer than 20.17? cm are discarded. what proportion of rods will be to four decimal places as )? using the results of part (b), if 5000? rods are manufactured in a day, how many should the plant manager expect to the answer from part b to find this answer. round to the nearest integer as )? if an order comes in for 10,000 steel rods, how many rods should the plant manager expect to manufacture if the order states that all rods must be between 19.9 cm and 20.1 up to the nearest integer.)

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
