Point A is at (-2,-7) and point B is at (7,4).
What is the midpoint of line segment AB?

You would expect 807 babies  to weigh between 3 and 6 pounds.

Step-by-step explanation:

Mean,pounds

Standard deviation,pounds

n=1500

The weights for newborn babies is approximately normally distributed.

Now,

Number of newborn  babies expect to weigh between 3 and 6 pounds
