To increase sales, a cell phone store began giving a free month of service on some cell plan purchases. Customers were unaware whether they would receive
the free month until after purchase. The store manager claimed that one in eight customers received the free month Nine customers each buy a cell phone plan
Let X = the number of customers that receive a free month of cell phone service.
Part A: Is X a binomial random variable? Explain. (3 points)
Part B: What is the mean and standard deviation of X? Provide an interpretation for each value in context. (4 points)

step-by-step explanation:

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'.
