Which statement describes the points on the normal curve that are one standard
deviation from the mean on either side?

Answer choices:
These points are inflection points of the curve.
The curve is almost horizontal at these points.
Half the area under the curve is between these two points.
The height of the curve at these points is half the peak height.

step-by-step explanation:

b and c

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
