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?

Use the distributive law to multiply. 3(4x + 5y + 6)

Solve 2^x=32 and rewrite this equation in a logarithmic form
