Which equation demonstrates the distributive property?
2 (5 + 7) = 2 ( + 5)
2 (5 + 7) = 2 5+ 2 7
(2 x 5) 7 = 2 x (5 x 7)
7 * (2 x 5) = 7 * (5 2)

Suppose medical records indicate that the length of newborn babies (in inches) is normally distributed with a mean of 20 and a standard deviation of 2.6. find the probability that a given infant is between 14.8 and 25.2 inches long.
