Answer:
(a) 0.675
(b) 0.3
Step-by-step explanation:
(Probability of functional red)
(Probability of non-functional red)
(Probability of functional green)
(Probability of non-functional green)
(a) The probability the board is functional is the probability that the red and the green resistors are functional.
(b) The probability that exactly one of the resistors chosen is functional is the probability that either red is functional and green is not or green is functional and red is not.
Factor using the AC method...
The answer is:
(x+6) (x+8)
Answer:
36 minutes when both pipes are working together
Step-by-step explanation:
capacity of tank = 5400 liters
Pipe A flow per mint. = 5400/90 = 60 liters per mint.
Pipe B flow per mint. = 5400/60 = 90 liters per mint.
Flow of A + B per mint. 60 + 90 = 150 liter per mint.
Therefore, 5400 / 150 = 36 minutes to fill the tank
its C the only one that makes a angle
