Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(3, −6), Q(0, 9), and R(−3, 0). Triangle P′Q′R′ has vertices P′(1, −2), Q′(0, 3), and R′(−1, 0).
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)
Answer:
P' = 1/3 P
reflection in the y-axis just changes the sign of all the x-values.
Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P
It is, however, similar to P.
Answer:
P' = 1/3 P
Step-by-step explanation:
Reflection in the y-axis just changes the sign of all the x-values. Since P" ≅ P', and P' is smaller than P, P" cannot be ≅ to P . It is, however, similar to P.

Tomás is gathering data about the sleeping habits of high school students. So far, he has completed 3 different surveys, each with 70 respondents.
What should Tomás expect as he continues his data-gathering process?
As the number of surveys increases, the mean of the sample means will approach ______, and the means will be ___________.
70 Points
Answer:
The population mean
Normally distributed
Please give me brainliest, I really need it.
a)As the number of surveys increases, the mean of the sample means will approach the population mean.
b)Means will be normally distributed.
What is a normal distribution?A normal distribution is a probability distribution that is symmetric about the mean, and data near the mean are more frequent than data far from the mean.
As the number of surveys increases, we will have more data.
So, the mean of the sample means will approach the population mean.
Means will be normally distributed because each survey has the same number of respondents.
Thus, a)as the number of surveys increases, the mean of the sample means will approach the population mean.
b)Means will be normally distributed.

On a BWIA flight, 2/3 of the
passengers are from Trinidad.
If there are 189 passengers
altogether, how many were
from Trinidad?
Answer:
126 passengers from Trinidad.
Step-by-step explanation:
Given that,
On a BWIA flight, 2/3 of the passengers are from Trinidad.
Total passengers = 189
We need to find how many were from Trinidad. It can be calculated by finding 2/3 of 189 such that,
[tex]P=\dfrac{2}{3}\times 189\\\\=126[/tex]
Hence, there were 126 passengers from Trinidad.
Colleen buys a movie for $32 and pays 9% sales tax. Her cousin, Brad, lives in another state. Brad buys the same movie for $38 and pays 7% sales tax. Who pays more sales tax? How much more?
HEEEELP!!!
Answer:
Colleen pays more sales tax. She pays $0.22 more sales tax than Brad.
Step-by-step explanation:
convert the percentage to a decimal and multiply by the amount paid to find sales tax
$32*0.09= $2.88
$38*0.07= $2.66
2.88-2.66= $0.22

Hey everyone. I need the answer to this ASAP!: Michael knows that 2 cans of paint is the exact amount he needs to paint a 10-foot by 12-foot wall. Graph the relationship between the total square feet of the walls and the number of paint cans necessary to paint them. Show your work or explain how you got your graph in part A . There is a picture of the graph attached.
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]2 cans = 10ft\ by\ 12ft[/tex]
Required
Graph the relationship between both parameters
First, calculate the area;
[tex]Area = 10ft * 12ft[/tex]
[tex]Area = 120ft^2[/tex]
This implies that: (2, 120) i.e. 2 cans for 120ft^2.
So we have:
(0,0) and (2,120)
(0,0) implies that: 0 cans for 0 square feet
Calculate the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{120 - 0}{2-0}[/tex]
[tex]m = \frac{120 }{2}[/tex]
[tex]m = 60[/tex]
The equation is:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = 60 * (x - 0) + 0[/tex]
[tex]y = 60 * (x )[/tex]
[tex]y = 60 x[/tex]

.On 1st March 2001, the ratio of Freddie’s age to his mother’s age was 1:11
On 1st March 2018, the ratio of Freddie’s age to his mother’s age was 2:5
Write the ratio of Freddie’s age to his mother’s age on 1st March 2030
Answer:
[tex]Ratio =16 : 31[/tex]
Step-by-step explanation:
Let
x = Freddie's age and y = His mother's age
Given
2001:= [tex]x : y = 1 : 11[/tex]
2018:= [tex]x +17: y + 17= 2 : 5[/tex]
Required
The ratio of their age in 2030
[tex]x : y = 1 : 11[/tex]
[tex]x +17: y + 17= 2 : 5[/tex]
Express as fractions
[tex]\frac{x}{y} = \frac{1}{11}[/tex] --- (1)
[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex] -- (2)
In (1), make y the subject
[tex]\frac{x}{y} = \frac{1}{11}[/tex]
[tex]y = 11x[/tex]
Substitute [tex]y = 11x[/tex] in (2)
[tex]\frac{x+17}{y+17} = \frac{2}{5}[/tex]
[tex]\frac{x+17}{11x+17} = \frac{2}{5}[/tex]
Cross Multiply
[tex]5(x +17) = 2(11x + 17)[/tex]
[tex]5x +85 = 22x + 34[/tex]
Collect like terms
[tex]22x - 5x = 85 - 34[/tex]
[tex]17x = 51[/tex]
[tex]x =3[/tex]
[tex]y = 11x[/tex]
[tex]y = 11*3[/tex]
[tex]y = 33[/tex]
This means that: In 2001, Freddie was 3 and his mother was 33
In 2030 (29 years after);
Freddie will be: 3 + 29 = 32
His mother will be: 33 + 29 = 62
So, the ratio is:
[tex]Ratio =32 : 62[/tex]
Divide by 2
[tex]Ratio =16 : 31[/tex]
