Caught speeding suppose police set up radar surveillance on the stanford street described in exercise 18. they handed out a large number of tickets to speeders going a mean of 28 mph, with a standard deviation of 2.4 mph, a maximum of 33 mph, and an iqr of 3.2 mph. local law prescribes fines of $100, plus $10 per mile per hour over the 20 mph speed limit. for example, a driver convicted of going 25 mph would be fined 100 + 10152 = +150. find the mean, standard deviation, maximum, and iqr of all the potential fines.

The mean would be 100+10*(28-20)=$180

The max would be 100+10*(33-20)=$230

The IQR is $205-$135=$70

Using a graphing calculator, the standard deviation is $38.94.

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'.
