Answer:
"simplify" it
Step-by-step explanation:
To convert from vertex form to standard form for a quadratic, eliminate parentheses and collect terms. In short, "simplify" it.
2 x 6.25
is equal to 12.5 in multiplication
Answer:
450 foe
Step-by-step explanation:
Answer: Our required probability is 0.39.
Step-by-step explanation:
Since we have given that
X be the exponentially distributed with mean life = 6 years
So, E[x]=6
So, our cumulative distribution function would be
We need to find the probability that the CPU fails within 3 years.
Hence, our required probability is 0.39.
The answer is 96 min, here is why:
x / 240 + x / 160 = 1
<span>2x + 3x = 480 </span>
<span>5x = 480 </span>
<span>x = 96 min
(</span><span>Drainage rate of first pipe = 480000/240 = 2000 l/min </span>
<span>Drainage rate of second tube = 480000/160 = 3000 l/min </span>
<span>Combined drainage rate = 5000 l/min </span>
<span>Time to drain = 480000/5000 = 96 min. )</span>
