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?

The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
