An expression is shown below:
10n^3 − 15n^2 + 20xn^2 − 30xn
part a: rewrite the expression so the gcf is factored completely.
part b: rewrite the expression completely factored. show the steps of your work

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?
