Suppose that the mean and standard deviation of the scores in a Statistics exam are 75 and 9.5 respectively. What minimum score

lyudmila [28]

The mean and standard deviation of the scores are 75 and 9.5 respectively.

The z-score is a means to find the probability of getting a particular score. This is calculated to be:

$z=\frac{x-\mu}{\sigma}$

where x is the score, μ is the mean, and σ is the standard deviation.

To be a part of the top 2.5 percent, the probability is:

$P=\frac{2.5}{100}=0.025$

The z-score for this probability, that is, P

The diameter and height of this cylinder are equal to the side length, S, of the cube in which the cylinder is inscribed. What i

N76 [4]

Volume of Cylinder = $\pi r^{2}h$
Based on what we're told:
r (radius) = $\frac{s}{2}$
h (height) = $s$
So:
Volume of cylinder = $\pi (\frac{s}{2})^{2}(s)$
= $\frac{1}{2}s^{3} \pi$
