Ashipyard makes a container ship that can withstand the total amount of weight w, which is normally distributed with mean of 600 tons and standard deviation of 60 tons. let us assume that the weight of a single container that will be loaded to the container ship is also normally distributed with mean of 4 tons and standard deviation of 0.4 tons. what is the maximum number of containers that the container ship can load and not exceed the ship’s weight limit with a probability of 90%?
i believe the answer is c.
well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
the answer should be 3.54 g/cm^3
