A composite figure is formed from a cone and a cylinder with the same base radius, and its volume can be calculated by multiplyi

olga55 [171]

The composite figure comprises of a cone balanced on top of cylinder

Step-by-step explanation:

The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r

Then the volume of the cone will be $V_{cone}$

Then the volume of the cylinder will be $V_{cylinder}$

$V_{cylinder} = \pi r^{2} h_{cylinder}$

The total volume of the composite figure will be V, where

$V= V_{cone} + V_{cylinder}$

$V = \frac{1}{3} \pi r^{2} h_{cone} +\pi r^{2} h_{cylinder}$

let the height of cone and cylinder be same

The volume of the composite figure will be $\frac{4}{3} \pi r$ $r^{2} h$

Hence $\frac{4}{3} = \frac{a}{b}$

Thecomposite figure comprises of a cone balanced on top of cylinder

Which measure of variability provides the most meaningful information about the following set of scores? Set of scores: 12, 12,

Alexus [3.1K]

Answer:

$Median$

Step-by-step explanation:

Median. Median in this case will give the most meaningful information about this data set.

<em>Reason</em>: There is at least one extreme score,32, in the distribution. It is an outlier that has a great effect on the mean:-

$m_9=\frac{148}{9}=16.44\\m_8=\frac{116}{8}=14.5 \ *11.8\% \ drop \ in \ mean.\\Median_9=15\\Median_8=14.5 \ *just \ a \ 3\% \ drop \ in \ median$

Hence median will give the most meaningful info about this data set
