According to data on the state of iowa, the amount of water used for cooking per household per month is normally distributed, with a standard deviation of 10.4 liters. a survey was carried out to estimate the population mean. with a sample size of 60 households, the mean quantity of water used for cooking was found to be 62.6 liters.
there is a 95% chance that the population mean lies between liters and liters.

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'.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
