The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0and 7minutes. find the probability that a randomly selected passenger has a waiting time greater than3.25minutes.

0.5357

Step-by-step explanation:

The waiting times are uniformly distributed between 0 and 7 minutes. We need to find the probability that a randomly selected passenger has a waiting time greater than 3.25 minutes.

The formula to use for uniform distribution is:

where,

b is the upper limit of the distribution which is 7 in this case.

a is the lower limit of the distribution which is 0 in this case.

x is the concerned value which is 3.25 in this case.

Using these values, we get:

This means, the the probability that a randomly selected passenger has a waiting time greater than 3.25 minutes is 0.5357

dont think so

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'.
