3w + 8 - w = 4w - 2(w - 4)
is an identity
3w-w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
2w - 2w = 8 - 8
0 = 0
zero equal to zero implies that any value of w satisfies the statement 3w + 8 - w = 4w - 2(w - 4) hence it is an identity.

Answer: The area under the part of a normal curve that lies within standard deviations of the mean is approximately . The mean, median, and mode are located at the center of the distribution. The area under the part of a normal curve that lies within standard deviations of the mean is approximately . The area under the part of a normal curve that lies within standard deviation of the mean is approximately . The normal distribution curve is symmetric about the standard deviation. A normal distribution curve is bell shaped.
