The distribution of actual weight of tomato soup in a 16 ounce can is thought to be bell-shaped with a mean equal to 16 ounces, and a standard deviation equal to 0.25 ounces. based on this information, between what two values could we expect 95% of all cans to weigh?

Between 15.5 and 16.5 ounces

Step-by-step explanation:

If the distribution is bell-shaped it follows a normal distribution.

In a normal distribution you except the 95% of the values between +-2 standard deviation from the mean.

lower limit = 16 - 2 * 0.25 = 15.5

upper limit = 16 + 2 * 0.25 = 16.5

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
