Answer: C) $6^3$

Step-by-step explanation:

From the given tiling, it can be seen that for any vertex selected in the tile, there are 3 hexagons surrounding the vertex.

Therefore, the naming convention= $6\times6\times6=6^3$

Hence, the name of the tilling = $6^3$

A tessellation of a flat surface is the tiling of a plane using one or more geometric shapes are called called tiles, with no overlaps and no gaps.They can be generalized to higher dimensions and a variety of geometries.

In a study of 24 criminals convicted of antitrust offenses, the average age was 60 years, with a standard deviation of 7.4 years

Alexxandr [17]

Answer: 56.9 years to 63.1 years.

Step-by-step explanation:

Confidence interval for population mean (when population standard deviation is unknown):

$\overline{x}\pm t_{\alpha/2}{\dfrac{s}{\sqrt{n}}}$

, where $\overline{x}$ = sample mean, n= sample size, s= sample standard deviation, $t_{\alpha/2}$ = Two tailed t-value for $\alpha$ .

Given: n= 24

degree of freedom = n- 1= 23

$\overline{x}$ = 60 years

s= 7.4 years

$\alpha=0.05$

Two tailed t-critical value for significance level of $\alpha=0.05$ and degree of freedom 23:

$t_{\alpha/2}=2.0687$

A 95% confidence interval on the true mean age:

$60\pm (2.0686){\dfrac{7.4}{\sqrt{24}}}\\\\\approx60\pm3.1\\\\=(60-3.1,\ 60+3.1)\\\\=(56.9,\ 63.1)$

Hence, a 95% confidence interval on the true mean age. : 56.9 years to 63.1 years.
