Let A be the event
and B be the vent
. Since the intersection of the events
, the events A and B are mutually exclusive.
The number is either odd or even. Since
, the events are mutually exclusive and exhaustive.
Correct choice is "the number is either odd or even".
The first reaction represented is a decomposition reaction due to the fact the bonded pair are being split apart.
The second equation is a single displacement because the B and C have switched places, which is the only change making it a single displacement. If there had been another bond and A had also moved, it would be double.
$260
I don’t know what model/formula you are supposed to be using.
But what I did first was calculated what 30% of 2700$ is.
2700 x .3 = 810
So it depreciates $810 per year.
$810 x. 3 years = 2430
2700 - 2430 = 260
In three years, the laptop will be worth $260
Answer is D... the -3 outside the absolute/parenthesis shifts is down
The answer is the first option. 7 left is not - 7 in this case. With these questions, you switch the signs. The vertical movement signs stay the same. Therefore, the answer is the first option.
