The solids are similar. Find the volume of solid B. Write your answer in terms of pi.

Temka [501]

Now, I’m not sure if I’m right because I’m not in college, but I’m pretty sure for solid A you divide the area which is 12 times the volume which is 4608. We do this because the volume of a cylinder is a•h but since we don’t know the height we divide. So after dividing I got 384. And since the solids are supposedly similar you will multiply the area of solid B which is 15 times 384 which equals 5,760. So the volume of solid B is 5,760 pi in.^3… (let’s hope this is correct)

In a study of 259 comma 995 cell phone users, it was found that 121 developed cancer of the brain or nervous system. Assuming t

IRISSAK [1]

Answer:

The probability of having 121 cases or less is:

$P(X$

This suggests that the study does not show any significantly effect of the use of cell phone in the probability of having brain or nervous system cancer. The use of cell phone does not appear to be a significant factor in the risk of having this type of cancer.

Step-by-step explanation:

We start by calculating the expected standard deviation of the population cases:

$\sigma=\sqrt{n\pi(1-\pi)}=\sqrt{259,995*0.000489*0.999514}\\\\\sigma=\sqrt{126.29}\\\\\sigma=11.24$

Then, to calculate the probability, we first calculate the z-score for 121 cases.

$z=\dfrac{X-\mu}{\sigma}=\dfrac{121-127}{11.24}=\dfrac{-6}{11.24}=-0.5338$

The probability of having 121 cases or less is:

$P(X$

This suggests that the study does not show any significantly effect of the use of cell phone in the probability of having brain or nervous system cancer. The use of cell phone does not appear to be a significant factor in the risk of having this type of cancer.
