Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
Answers
(A) The scale factor of the dilation that transforms Triangle PQR to Triangle P'Q'R' is 1/4
(B) Coordinates of Δ P"Q"R"
P" (-1,0)
Q"(0,-1)
R"(2,-1)
(C) Triangles PQR and P"Q"R" are not congruent.
Given
ΔPQR is transformed into ΔP'Q'R'
Coordinates of P, Q, R are
P (4,0),
Q(0,-4)
R(-8,-4)
Coordinates of P'Q'R' are
P'(1,0)
Q'(0,-1)
R'(-2,-1)
(A) By Distance formula we can find the distance between P Q and P'Q'
Distance formula =
Where D = Distance between two points
from distance formula we can write that
PQ =
Similarly
P'Q'=
PQ /P'Q' = 4
hence the scale factor of dilation is 1/4 (Compression)
(B )The Coordinates of Reflection about y axis can be written for a point
So the Coordinated of Δ P"Q"R" can be written as
P" (-1,0)
Q"(0,-1)
R"(2,-1)
(C) ΔPQR and ΔP"Q"R" are similar triangles but they are not congruent because their sides are not equal in size.

Answer:
24.44 percent
Step-by-step explanation:
F=Friday
S=Saturday
P(F or S)= 20/90+22/90-20/90=22/90
22/90 as percentage is 24.44 percent
Answer:
For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.
Step-by-step explanation:
Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

The distances between the points are:
4) 45) 8.86) 67) 10How to find the distances between the points?The distance between two points (a, b) and (c, d) is given by:
[tex]distance = \sqrt{(a - c)^2 + (b - d)^2}[/tex]
4) Here the points are (-5, 2) and (-5, 6) so the distance is:
[tex]distance =\sqrt{(-5 - (-5))^2 + (6 - 2)^2} = 4[/tex]
5) Here the points are (4.5, -3.3) and (4.5, 5.5), so the distance is:
[tex]distance = \sqrt{(4.5 - 4.5)^2 + (-3.3 - 5.5)^2 } = 8.8[/tex]
6) Here the points are (5 + 1/2, -7 - 1/2) and (5 + 1/2, -1 - 1/2), so the distance is:
[tex]distance = \sqrt{(5.5 - 5.5)^2 + (-7.5 - (-1.5)^2)} = 6[/tex]
7) Here the points are (-2.25, -8) and (7.75, -8), so the distance is:
[tex]distance = \sqrt{(-2.25 - 7.75)^2 + (-8 + 8)^2} = 10[/tex]

n = 16 * 4
n = 64
n = 64 will be your answer.

The mode cannot be determined.
Step-by-step explanation:
The reason it cannot be determined is because there is no common value since they all appear just once.
Answer:
J. The mode cannot be determined.
Step-by-step explanation:
Mode cannot be directly examined with a box & whisker plot such as this. The nature of this sort of representation just doesn't make it possible.
To find mode, the ideal way is to set the data of numbers from least to greatest (in order), then examine which numbers shows up the most.
Fun fact: Another great way to represent the mode is by using a DOT Plot; this is where you plot each number based on how many times it shows up on a graph. The number with the most marks is the mode because that number is what shows up most in the data.
Provided in the attachment is an example of a box plot; of which the mode is 100 as it has the most marks.
