What is the standard deviation? Round to the nearest hundredth.

Explanation:

To find the standard deviation of a set of numbers, first find the mean (average) of the set of numbers:

10+15+19+35+27+446=25

Second, for each number in the set, subtract the mean and square the result:

(10−25)2+(15−25)2+(19−25)2+(35−25)2+(27−25)2+(44−25)2=826

Then add all of the squares together and find the mean (average) of the squares, like this:

8266=137.67

Finally, take the square root of the second mean:

137.7−−−−√=11.7.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
