Answer: fracture

Explanation:

Minerals are formed by crystallization from magmatic liquids or thermal solutions, by solid-state recrystallization and further, as the product of chemical reactions between solids and liquids. Fracture: When minerals do not break flat but according to an uneven surface. The types of fracture can be classified into:

• Conchoidal: when the mineral breaks, leaving curved marks similar to the growth lines of shells. Ex: quartz.

• Irregular: When the mineral breaks randomly, forming rough and uneven surfaces. Ex: tourmaline.

• Fibrous: when the mineral breaks down in the form of fibers. Ex: chrysotile.

• Serrated: when the mineral breaks up according to a jagged surface with sharp edges. Ex: gold.

Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.

grin007 [14]

Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26
