Okay, So To Find The Mean, We Need To Look At The Values.
-588,-838,-691,-818,-846,-725,-605,-732,<span>-750
</span>So, We Add Them, Then Divide.
-588+-838+-691+-818+-846+-725+-605+-732+-750

This Is -732.555556.Rounded Is -733
Now, The Median. The Middle Value.
The Middle Value Is -846.
So, The Mean Is A, 113 Points Higher.
Step-by-step explanation:
n(s) for 2 cubes =6×6=36
n (5, even) = 3
(5,2) (5,4) & (5,6)
so, probability = 3/36 = 1/12
Hi There!
Out of the 120 students at a summer camp, 72 signed up for canoeing. There were 23 students who signed up for trekking, and 13 of those students alsosigned up for canoeing.
Use a two-way table to organize the information and answer the following question:
Approximately what percentage of students signed up for neither canoeing nor trekking?
10%
12%
38%
32%
Answer:10%
Answer:
C. not similar, dilations are involved
Step-by-step explanation:
For geometric figures, such as triangles, we generally study a couple of kinds of transformations.
One is the "rigid transformation" which lets us move, rotate, or reflect the figure any way we like, but we keep it the same size—as though it were cut from cardboard or anything else that holds its shape and size. Any figures transformed by a rigid transformation are <em>congruent</em>.
Another is very much like the "rigid transformation", but <em>dilation</em> is involved. That is, the figure is allowed to be stretched or shrunk <u>uniformly</u> (by the same factor in every direction). Figures transformed in this way are <em>similar</em>, but are not congruent.
In this diagram, your triangle has been reflected and <em>changed in size</em> by a different factor horizontally than vertically. Hence <em>dilation</em> is involved (answer choices A or C), but because the factors are different, the figures are <em>not similar</em> (answer choice C).

<em>Comment on the answer choices</em>
Rotations may be involved in similarity transformations, too. For some reason, that possibility was left off of choices A and C. (On the other hand, rotation is equivalent to a suitable set of reflections.)
