An ambulance with a siren emitting a whine at 1,600 Hz overtakes and passes a cyclist pedaling a bike at 2.44 m/s. After being passed, the cyclist hears a frequency of 1,590 Hz. How fast is the ambulance moving?

Explain your work. Thanks! :)

Let x be the number of minutes after 11:00 that a bus leaves the bus station. Assume that the distribution of times is approximately normal w/ a mean of fifteen and standard deviation of 4 minutes.

(1) if a person gets to the bus station at 11:10, what is the probability thtat the person has missed the bus?

(2) If a person is willing to risk a 20% chance of not making the bus, what is the maximum number ofminutes after 11:00 that the person can reach the station?

(3) What time should the person reach the station to have a 50/50 chance of catching the bus?

I AM SO CONFUSED! Your help is truly appreciated!

I've been experimenting with flyback transfomers lately. I just hold a piece of metal in my hands for the coil to arc over. Most of the time it doesn't hurt that much. Will this shorten my lifespan, im just curious?

if you dont know what a flyback is, click:

use a triple integral to find volume of the tetrahedron enclosed by the coordinate planes and the plane
2x+y+z=22

i did ʃʃʃdzdydx
0<=x<=2
0<=y<=4-2x
0<=z<=22-2x-y

i got the answer to be 72 and thats wrong. i tried to go back to see where i messed up but nothing caught my eye

I got a PH testing kit and it tests from 6.2(light lime green) to 7.4(Sky blue). now my question is, if i tested a solution that was say in between 12 and 14 would it be dark blue? or would it be yellow? because i heard a ph reading of 12 would make yellow, but that doesn't make any sense since it gets darker blue on the chart the further the number goes up.
