Answer:
C.20
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the difference between the two bounds, divided by 2.
In this question:
Lower bound: 70
Upper bounf: 110
Margin of error:
Thus the correct answer is given by option C.
Answer:
2023 rabbits
Step-by-step explanation:
The exponential model consists of the following expression:
Where:
- Initial population.
- Increase rate.
- Time
- Current population.
The initial population and increase rate are, respectively:
![r = \sqrt[4]{\frac{17}{12} }](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B4%5D%7B%5Cfrac%7B17%7D%7B12%7D%20%7D)
The exponential model that predicts the population of rabbits is:
Lastly, the expected population for the year 1996 is:
Answer:
Table D
Step-by-step explanation:
you have to solve .3x = 1.5. this equals 5....since 5 is doubled to 10 you have to double 1.5 to 3.0
