Given that you are seated next to a stranger on an airplane and you start discussing various topics such as where you were born (what state or country), what your favorite movie of all time is, your spouse's occupation, and so on.
Since each topic is independent we find that probability for success in each topic = constant = 1/50 = 0.02
X no of topics that match is binomial with n = 17 and p = 0.02
Required probability
= Probability to find that you match on at least one of them
=
It would not be surprising as probability is reasonably large.
Answer:
y=-4x-4
Step-by-step explanation:

y=mx+b where m=slope and b=y-intercept.
I think the answer would be the second one or B. the number of hours billed
Answer:
This is khan academy. I am pretty sure they have a video for this but whatever.
Step-by-step explanation:
So we are using sin, cosine, and tan. 3.4 is the hypotenuse. the side is X. The angle is 20 degrees. So, this is adjacent to hypotenuse. This means it is cosine.
3.4cos(20)= around 3.19
And thats that! let me know if this is wrong and I will try to fix it.
