Answer:
V≈434.89
Step-by-step explanation:
V=4/3πr^3
plug the numbers in and you get 434.89
The question is kind of all over the place. Can you clear it up a bit because it sound to me that all you have to do is simple addition and subtraction hun.
Well I’m getting 574.5 for the first one and not getting the same for any of them.
Answer:
Probability: 131/195
Step-by-step explanation:
Total cookies:
7 + 6 + 2 = 15
Total candies:
14 + 12 = 26
Probability of raisin:
2/15
Probability of peppermint:
14/26 = 7/13
Probability of both:
2/15 + 7/13
131/195
Answer:
The option B is True
Step-by-step explanation:
Solution
nA < nB
Thus
1/√nA > 1/√nB
SD/√nA > SD/√nB
So,
SE (A) > SE (B).......(1)
Zα/2 SE (A) > Zα/2 SE (B)
Now
E (A) > E(B) this is the margin error
Since SE fro sample A is larger than SE for sample B
We have that,
The length = ZE
Therefore, option B is correct because here, we know that as the sample size increases or goes higher the length of the confidence interval decreases
In this case, the sample size is large for B then A.
Thus, the length of confidence interval based on A is larger than the length of confidence interval Based on B Since SE is large For A than B
