Randomly selecting a seventh grader from a school that has 250 sixth graders, 225 seventh graders, and 275 eighth graders

The probability is P = 0.32

Step-by-step explanation:

Here i guess that the question is: "what is the probability of randomly selecting a seventh-grader".

The data that we have is:

We have 250 sixth graders, 225 seventh graders and 275 eight graders, this adds to a total of 700 options.

The probability of randomly selecting a seventh-grader is equal to the number of seventh-graders divided the total number of possible options, in this case, 700.

So we have P = 225/700 = 0.32

This means that the probability of randomly selecting a seventh-grader is equal to 0.32

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'.

no its the same as every other grade
