Answer:
0.77
Step-by-step explanation:
From the information given:
The breakdown time (a)= 3 hours
The breakdown rate (λ) = 1/a = 1/3
Average flow time in the system (W) = 2.305 hours
For the entire system;
The average down machines L = Wλ
= 2.305 × (1/3)
= 0.77
Answer:
D.
Step-by-step explanation:
A Cubic Function goes up and down forever, as well as left and right.
Answer:
2x² + 19x + 45
Step-by-step explanation:
(x + 5)(x + 1) + (x + 5)(x + 8) ← expand both sets of factors using FOIL
= x² + 6x + 5 + x² + 13x + 40 ← collect like terms
= 2x² + 19x + 45
The answer is A. Each time it is multiplied by a higher number so 1 x 2 = 2 . 2 x 3 = 6 . 6 x 4 = 24 . 24 x 5 = 120 . 120 x 6 = 720
