kicyunya [14]

Answer:

B

Step-by-step explanation:

A cylinder is like circles staked on top of each other so you want to find the are of the top circle which is 28.26 because pi r^2 (3^2)*3.14. now you found the area of the top circle. The height is 10.5 so that means there are 10.5 layers so you multiply 28.26 by 10.5 i know its confusing im new to brainly but hopefully this answer helped you  You will get 296.73 because i rounded pi to 3.14 but the answer is B

The distribution of blood cholesterol level in the
qaws [65]

Answer: A. Mean of sampling means =\mu=168\ Mg/dl

Standard deviation of sampling means =2.86\ mg/dl

B. The probability that your sample has mean less than  165 is 0.1492 .

Given : The distribution of blood cholesterol level in the

population of young men aged 20 to 34 years is close to normal with

mean \mu= 168 Mg/dl and standard deviation \sigma= 35 mg/dl.

Sample size : n= 150

Let \overline{x} sample mean values.

A. The mean and the  standard deviation of the distribution of the sampling means would be :

Mean of sampling means =\mu=168\ Mg/dl

Standard deviation of sampling means = \dfrac{\sigma}{\sqrt{n}}=\dfrac{35}{\sqrt{150}}

=\dfrac{35}{12.2474487}\\\\=2.85773803649\approx2.86\ mg/dl

The probability that your sample has mean less than  165 would be

P(\overline{x}

Hence , the probability that your sample has mean less than  165 is 0.1492 .
