Need really really really badly! lol hi : ) i really need with this statistics question within 10 minutes. i do not know where to start and math is not my strong suit. i don't even know where to start so your would be greatly appreciated < 3 this is worth 20 points!

a football quarterback has 2 more chances to throw a touchdown before his team is forced to punt the ball. he misses the receiver on the first throw 30% of the time. when his first throw is incomplete, he misses the receiver on the second throw 10% of the time. what is the probability of not throwing the ball to a receiver on either throw?

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?

What is the axis of symmetry of the function f(x)=-(x+ 9)(x-21)

4+(2+x) can you me solve this problem
