Answer:
-6+4p
Step-by-step explanation:
-(6-4p)
-1(6-4p)
-1*6=-6
-1*-4p=4p
-6+4p
Answer:
The probability of a event is a number between 0 and 1 or 1 and 10 or 1 and 100.
Step-by-step explanation:
The correct answer is - The probability of a event is a number between 0 and 1 or 1 and 10 or 1 and 100.
Reason -
Probability - It is a number between 0 and 1
Sample space - All the possible outcomes of an experiment.
Outcome - One of the individual results that can occur in an experiment.
Event: A subset of the sample space
Compound event : A event with more than one outcome.
2 gallons divided between 9 people would equal 0.222222222 gallons per person
You can see how this works by thinking through what's going on.
In the first year the population declines by 3%. So the population at the end of the first year is the starting population (1200) minus the decline: 1200 minus 3% of 1200. 3% of 1200 is the same as .03 * 1200. So the population at the end of the first year is 1200 - .03 * 1200. That can be written as 1200 * (1 - .03), or 1200 * 0.97
What about the second year? The population starts at 1200 * 0.97. It declines by 3% again. But 3% of what??? The decline is based on the population at the beginning of the year, NOT based no the original population. So the decline in the second year is 0.03 * (1200 * 0.97). And just as in the first year, the population at the end of the second year is the population at the beginning of the second year minus the decline in the second year. So that's 1200 * 0.97 - 0.03 * (1200 * 0.97), which is equal to 1200 * 0.97 (1 - 0.03) = 1200 * 0.97 * 0.97 = 1200 * 0.972.
So there's a pattern. If you worked out the third year, you'd see that the population ends up as 1200 * 0.973, and it would keep going like that.
So the population after x years is 1200 * 0.97x
