Answer:

The Triangle is reflected across two lines.

 A composition means two or more transformation has taken place.

When the composition of two reflections between Intersecting line takes place, we consider it as equivalent to Rotation.

An Isometry means neither the change in shape,size, nor Angles (Interior as well as Exterior), that is two shapes after transformation are Congruent.

This kind of Isometry which is composition of reflections is called  

 Option D: Glide reflection

Papessa [141]

Answer:

Stem     Leaf

______________

0        |  4  8

1         |  0  5

2        |  5

3        |  3  6  6

4        |  0  0  9

5        |  0  

6        |  3  4  6

______________

Notation : 0|4 means 04 or 4 , 4|9 means 49/

For this case we can conclude that the distribution is approximately symmetrical.

For the 5 number summary we have

Minimum = 4 , Q1= 20 , Median =36, Q3= 49.5 , Maximum = 66

The mean for this case is Mean= 35.93

And as we can see since the mean is similar to the the median

The mode is 40 and 36 (bimodal distribution) with frequency of 2

Step-by-step explanation:

Data given:

4 15 10 8 33 25 36 40 36 66 63 50 64 49 40

For this case the first step is order the dataset on increasing way and we got:

4  8 10 15 25 33 36 36 40 40 49 50 63 64 66

Now we can construct the stem leaf plot like this:

Stem     Leaf

1         |  0  5

2        |  5

3        |  3  6  6

5        |  0  

6        |  3  4  6

Gabe has 60 coins consisting of quarters and dimes. The combined value of the coins is $9.45. Find how many quarters and dimes G
Ugo [173]
We could say that dimes = x and quarters = 60 -x

Then we use the value of the coins 

10(x) + 25(60-x) = 945

I did 945 because I am doing this in cents not dollars but the answer would still work because it is asking for the amount of coins.

10x + 1500 - 25x = 945

-15x = -555

x = 37 

Dimes = x = 37
Quarters = 60 - x = 60 -37 = 23
