Answer:
B
Step-by-step explanation:
The information on the graph is almost symmetrical, because the lines look almost the same length on both sides.
Answer:
Good luck :)
Step-by-step explanation:
S=2πrh+2πr ²
subtract 2πr ² from each side
S -2πr ² = 2πrh
divide by 2πr from each side
(S -2πr ² )/ 2πr = h
Answer:
1. 24,000,000, i believe you divide, 300,000/80.
2. 4.065 seconds, i also believe you divide 5000m/1230.
Answer: 2185
Step-by-step explanation:
Let p be the proportion of visitors are campers.
Given : The Tennessee Tourism Institute (TTI) plans to sample information center visitors entering the state to learn the fraction of visitors who plan to camp in the state.
The prior proportion of visitors are campers : p=0.35
Allowable error : E= 2%= 0.02
We know that the z-value for 95% confidence = ![z_c=1.96](https://tex.z-dn.net/?f=z_c%3D1.96)
Then by Central Limit Theorem , the required sample size would be :
![n=p(1-p)(\dfrac{z_{c}}{E})^2](https://tex.z-dn.net/?f=n%3Dp%281-p%29%28%5Cdfrac%7Bz_%7Bc%7D%7D%7BE%7D%29%5E2)
![\Rightarrow\ n=0.35(1-0.35)(\dfrac{1.96}{0.02})^2\\\\ n= 0.35(0.65)(9604)](https://tex.z-dn.net/?f=%5CRightarrow%5C%20n%3D0.35%281-0.35%29%28%5Cdfrac%7B1.96%7D%7B0.02%7D%29%5E2%5C%5C%5C%5C%20n%3D%200.35%280.65%29%289604%29)
Simply , we get
[Rounded to the next whole number.]
Hence, the smallest sample size to estimate the population proportion of campers =2185
