Answer:And Explanation
Initially the number of rabbits in the preserve are: 6
After one year the population of rabbits are doubled this means that the population of rabbits at the end of one year is: 2×6=12
Again after one year the population of rabbits are doubled this mean that at the end of second year the population of rabbits are: 12×2=24
and at the end of third year the population of rabbits is: 24×2=48
Hence, the points are plotted as follows:
(0,6)
(1,12)
(2,24)
and (3,48)
We know that the y-intercept is the point where x-value is zero.
Hence, here we have y-intercept at (0,6
-9 because a negative plus a negative is a negative so -5+-4 or -5-4 is -9
1/4
probability of getting a tail or a head is 50% or 1/2
If you want a tail then a head, it’s 1/2 *1/2 =1/4
Answer:
P(500< xˉ
<510)≈0.95

To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 180 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 180 is 100%, so we can write it down as 180=100%.
4. We know, that x is 30% of the output value, so we can write it down as x=30%.
5. Now we have two simple equations:
1) 180=100%
2) x=30%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
180/x=100%/30%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 30% of 180
180/x=100/30
(180/x)*x=(100/30)*x - we multiply both sides of the equation by x
180=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x
180/3.33333333333=x
54=x
x=54
now we have:
30% of 180=54
