Which interval contains the median number of cars in line?
Drivers pay a toll to pass over a busy bridge, and
there are many toll booths that collect money. The city
manager counted the total number of cars waiting to
pay their tolls at 15-minute intervals during the day for
a total of 50 observations. The histogram below shows
the results.
O 10-20 cars
0 20-30 cars
30-40 cars
40-50 cars

answer: the first graph

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'.
