Answer:
6/25
Step-by-step explanation:
all you need to do is to look for common factors of both the numerator and the denominator and you keep on breaking it down
= - 4.2x + 3 + 2.5x - 6
= 2.5x - 4.2x + 3 - 6
= - 1.7x - 3
-2s + 14 > 4s + 8
6 > 6s
s < 1
So it's {-<span>∞, . . . . ., -2, -1, 0}

Answer : Probability that the pumping system will fail on any given day = 0.005
Explanation:
Probability that only older pump fail = P(A) = 0.10
Probability that only newer pump fail = P(B) = 0.05
Since they are independent events ,
then the conditions will be
P(A∩B) = P(A). P(B)
= 0.10 ×0.05
= 0.005
Hence, the probability will fail on any given day = 0.005
