Match each function with the correct information about its vertex and zeros. The vertex is (−2,−1) and the zeros are (−3,0) and (−1,0). The vertex is (2,−1) and the zeros are (3,0) and (1, 0). The vertex is (2,1) and the zeros are (3,0) and (1,0). f(x)= x2+4x+3 f(x)=−(x − 2)2+1 f(x)=x2−4x+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?
