Answer:
2/7
Step-by-step explanation:
Like it says it is the same as monty hall with 3 doors.
You have 7 doors, the probability of the car being in each door is 1/7. After you pick one the probability of the car being in the other doors is 6/7, then he opens 3 doors showing only goats but the probability of it being in one of all the remaining doors is still 6/7 because you made a 1/7 probability choice when you picked your door. Meaning the remaining 3 doors have a probability of 6/7, then 2/7 each
I believe the answer is:
Alexia arrives 1 hour later than Hailey.
Good luck! XD
Ah, function problems, I had this in my math class around 2-3 weeks ago. So f and g is the function here.
TO SOLVE:
Simply look at where each plot is at. f(-3) is at (0, -3). So we will substitute -3 into f(-3).
Now, our equation should look like:
-6•(-3)-5•g(-7).
We can now take a look at the function, g. We can see that g(-7) lays at (-7, 6). We only need the Y here so it will be 6. Now, plug it in:
-6•(-3)-5•6=
=18-30
=-12
So thus, -12 is the answer!
If you believe this answer helped, please rate it! Please give me your honest opinion, meaning you may give me 1/5 depending on how good I explained so I can improve it!
