Scale Factor is defined as the ratio of the size of the new image to the size of the old image. The center of dilation is a fixed point in the plane.
If the scale factor is more than 1, then the image stretches. If the scale factor is between 0 and 1, then the image shrinks. If the scale factor is 1, then the original image and the image produced are congruent.
To dilate a figure by a scale factor, all the coordinates are multiplied by the scale factor.
The coordinates of point A are (8, 6). A dilation by a scale factor of 0.5 means that the figure will be reduced. The new coordinates will be:A
Therefore, the FIRST OPTION is correct.

Answer:
(X - 4)(x - 4)
Step-by-step explanation:
x2 - 8x + 16
What two numbers multiply to 16 and add to -8
-4 * -4 = 16
-4 +-4 = -8
(x-4) (x-4)
(x-4)^2
Answer :
21 years old person picked at random did indicate that the town should build a high school.
Step by Step explanation:
The Problem statement has been added already in the details of this question. Please refer to that. The table for this problem statement is attached.
So, as asked :
<u>An eligible voter is picked at random. If this person is 21 years old, do you think he would indicate that the town should build a high school? Why or why not</u>
As we can see in the table, the age group of 18-25 years old also contains a person aged 21 years.
And we can see that:
Majority of the eligible voters in the age group of 18-25 years old said yes. Mainly , total of 61 out of 75 eligible voters in this age group said "yes" meaning that a 21 years old in this age group would also have said "yes".
Which means the 21 years old indicated the town should actually build a high school.
