Point A, located at (-11, -7) on the coordinate plane, is reflected over the x-axis to form
point B. Then point B is reflected over the y-axis to form point C. What are the coordinates
of points B and C?

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.
