Step-by-step explanation:
For the question 5, Noah is right, as 75/100 x 10 = 7.5, and 25/100 x 30 = 7.5
So both of then have equal amount, therefore, Noah is right.
Answer:
1/2 ; 1/3 ; 1/6
Step-by-step explanation:
Given :
Ben ~ exp(1)
Max ~ exp (2)
Yolanda ~ exp(3)
Ben :
X ~ exp(1)
Max:
Y ~ exp(2)
Yolanda :
Z ~ exp(3)
Probability that Yolanda is served first :
P(Z < (X, Y)) = Z /(x + y + z) = 3 /(1 + 2 + 3) = 3/6 = 1/2
Probability that Ben is served before Yolanda :
P(X < Z) = 1/ (1 + 2) = 1/3
Expected waiting time for first person served :
First person served = 1
Total = (1 + 2 + 3) = 6
Expected waiting time; E(x) :
E(x) : 1 / 6
3 pizzas=2 side dishes
8 side dishes=8/2 times 3
=12 pizzas
Answer: c
Step-by-step explanation: because yes
You can use zero as a starting point and then plot based on the direction of your number, so say you have a -1. You would plot that -1 to the left of 0 and any other negative numbers you have. Regarding positive numbers, they would all go to the right of zero so if you had to plot +1 you would plot that to the right of zero. I attached a photo to help you :)
