1. You must subtract both sides by 1/4n to end up with 2/4n-18=-4
2.Then you add 18 to both sides to end up with 2/4n=14
3. Now you multiply both sides by 2/4 , aka 1/2 to get n by itself, and you will end up with n=7
n=7 is your answer!
The answer is D because remember an open dot means that it isn't part of the answer and a closed dot means that it is part of the solution. So if 62 is the minimum number that they can retire at, they can also retire later than that. so it's D.
Answer:
39.10%
Step-by-step explanation:
The given timeout distributions are:
Exp (1/10), Exp (1/12)
The equation to use is the following:
F (x) = 1 - e ^ (- a / b); x> 0
So the probability is:
P (food has not arrived after waiting 25 minutes | R) = e ^ (- 10/10) = 0.3679
P (food has not arrived after waiting 25 minutes | S) = e ^ (- 12/15) = 0.2865
So:
P (food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) + (food has not arrived after waiting 25 minutes | S) * P (S)
Replacing:
P (food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 + 0.2865 * 2/3 = 0.3136
However:
P (R | food has not arrived after waiting 25 minutes) = (food has not arrived after waiting 25 minutes | R) * P (R) / P (food has not arrived after waiting 25 minutes)
P (R | food has not arrived after waiting 25 minutes) = 0.3679 * 1/3 / 0.3136 = 0.3910
It means that the probability is 39.10%
Answer:
8+8/-8-4
16/-12
4/-3
8=4/-3(-8)+b
8*3=12+b
24=12+b
12=b
y=-4/3+12
