Apassenger train has 15 cars that each hold the same number of passengers. the train is filled with 1,020 passengers. how many passengers does each car hold? enter m for multiplication or d for division.

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?

Find the difference (8ab+a+2) - (3ab+6)
