A sphere has a radius of 5 inches. What is its volume? Sphere V = 4 3 πr3 1. Substitute the radius into the formula: V = 4 3 π(53) 2. Evaluate the power: V = 4 3 π(125) 3. Simplify: V = in.3

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?

Calculate the missing value. round the answer to on decimal place. start with 70, increase it by 21%, and end up with
