A Crayon is shown here.
Aleks04 [339]

The volume of the single crayon is 89.5 cm³, then the total volume of the crayons will be 2148 cm³. Then the correct option is D.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A Crayon is shown here.

There are 24 crayons in a box.

The approximate total volume of the crayons will be

Total Volume of crayons = 24 × volume of the single crayon

The crayon is the combination of the cone and the cylinder

Then the volume of the single crayon (V₁) will be

\rm V_1 = \left ( \dfrac{1}{3} \times \pi \times r^2 \times h  \right ) + \left (  \pi \times r^2 \times h  \right )\\\\\rm V_1 = \left ( \dfrac{1}{3} \times \pi \times 1.5^2 \times 2  \right ) + \left (  \pi \times 1.5^2 \times 12  \right )\\\\V_1 = 4.712 + 84.82\\\\V_1 = 89.535 \approx 89.5

Then the Total volume will be

Total volume = 24 × 89.5

Total volume = 2148 cm³

The statistics of nequals22 and sequals14.3 result in this​ 95% confidence interval estimate of sigma​: 11.0less thansigmaless t
dimulka [17.4K]
Answer: no, the confidence interval for the standard deviation σ cannot be expressed as 15.7 \pm 4.7

There are three ways in which you can possibly express a confidence interval:

1) inequality
The two extremities of the interval will be each on one side of the "less then" symbol (the smallest on the left, the biggest on the right) and the symbol for the standard deviation (σ) will be in the middle:
11.0 < σ < 20.4
This is the first interval given in the question and it means <span>that the standard deviation can vary between 11.0 and 20.4

2) interval
</span>The two extremities will be inside a couple of round parenthesis, separated by a comma, always <span>the smallest on the left and the biggest on the right:
(11.0, 20.4)
This is the second interval given in the question.

3) point estimate </span><span>\pm margin of error</span>
This is the most common way to write a confidence interval because it shows straightforwardly some important information. 
However, this way can be used only for the confidence interval of the mean or of the popuation, not for he confidence interval of the variance or of the standard deviation.

This is due to the fact that in order to calculate the confidence interval of the standard variation (and similarly of the variance), you need to apply the formula:
\sqrt{ \frac{(n-1) s^{2} }{\chi^{2}_{\alpha / 2} } } \leq \sigma \leq \sqrt{ \frac{(n-1) s^{2} }{\chi^{2}_{1 - \alpha / 2} } }

which involves a χ² distribution, which is not a symmetric function. For this reason, the confidence interval we obtain is not symmetric around the point estimate and the third option cannot be used to express it.
