Which function models the area of a rectangle with side lengths of 2x – 4 units and x + 1 units? A. f(x) = 2x2 – 4x + 4 B. f(x) = 2x2 + 8x – 4 C. f(x) = 2x2 – 8x + 4 D. f(x) = 2x2 − 2x − 4

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.
