Answer: The expected waiting time is
Step-by-step explanation:
Since we have given that
Average waiting time for slow elevator = 3 min
Average waiting time for fast elevator = 1 min
probability that a person choose the fast elevator =
Probability that a person choose the slow elevator =
So, the expected waiting time would be
Hence, the expected waiting time is

Answer:
62 oz
Step-by-step explanation:
Let the volume of water to add be x so that the new volume will be (30+x) oz
The new concentration is now 15%, expressed in decimal as 0.15 and it is found by dividing the initial concentration by new volume
The volume of water to add is equal to 62 oz
Answer:
Step-by-step explanation:
f(x) = x² - 2x + 5
1) f(2) = (2)² - 2(2) + 5 = 5
2) f(-3) = (-3)² - 2(-3) + 5 = 20
3) f(0) = (0)² - 2(0) + 5 = 5
4) f(5) - f(-2) = (5)² - 2(5) + 5 - [(-2)² - 2(-2) + 5 = 20 - 13 = 7
5) f(1) + f(6) = (1)² - 2(1) + 5 + [(6)² - 2(6) + 5 = 4 + 29 = 33
