Answer:
7.487 tons
Step-by-step explanation:
There are 2,000 pounds in one ton, so you divide 14,974 by 2,000 to get your answer.
Answer:
47 hours
Step-by-step explanation:
564/12 = 47
Answer:
a)e^-(λ20891)
b)1-e^-(λ30598)
c)1-e^-(λ30598)-e^-(λ20891)
Step-by-step explanation:
The probability density function (pdf) of an exponential distribution is
f(x,λ)=λe^-(λx) for x>0, and 0 for x<0
The cumulative distribution function is given by
F(x,λ)=1-e^-(λx) for x>0, and 0 for x<0
P(X≥20891)=1-P(X≤20891)=1-F(20891,λ)=e^-(λ20891)
P(X≤30598)=F(30598,λ)=1-e^-(λ30598)
P(20891≤X≤30598)=F(30598,λ)-(20891,λ)=1-e^-(λ30598)-e^-(λ20891)
Both exponential i.e 5 ^x
A is true, surprisingly.
B cannot be true, it alternates.(rule of indices negatives by positive exponent = positive, negative by negative , but -5 x -5 x -5 = + 5)
I'm only imaginging, but C must be right, since it increases exponentially, as opposed to D which only increases quadratically.
Answer:
waste
Step-by-step explanation:
Try to think of something that doesn't involve energy and you won't get very far. Even thinking—even thinking about energy!—needs some energy to make it happen. In fact, everything that happens in the world uses energy of one kind or another. But what exactly is energy?
Energy is a bit of a mystery. Most of the time we can't see it, yet it is everywhere around us. Revving car engines burn energy, hot cups of coffee hold energy, street lights that shine at night are using energy, sleeping dogs are using energy too—absolutely everything you can think of is using energy in one way or another. Energy is a magical thing that makes other things happen. Everything in the world is either energy or matter ("stuff" around us) and even matter, when you really get down to it, is a kind of energy!
