The probability of picking the blue card is 1/2 each time.
The probability of picking it BOTH times is
(1/2)•(1/2) = 1/4. (25%)
The scale factor in the question given above is: 2 See the explanation below.
<h3>What is a scale factor?</h3>
In math, the scale factor is the extent or ratio by which a geometrical shape is enlarged or reduced.
<h3>What is the explanation for the above answer?</h3>
We know that:
- The distance from point Q to point A is 1.25
- The distance from point A to point A' is 1.25
Given the above, the distance from point Q to point A' is 2.50. This is double the distance from point Q to point A.
The scale factor is 2.
1.25 + 1.25 = 2.50
2.50 / 1.25 = 2

Answer:
The Slope of both the lines is the same.
Step-by-step explanation:
Given two co-ordinates (x1, y1) and (x2, y2), the slope of a line can be found using the formula:
![slope = \frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=slope%20%3D%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
For the diagonal line of the first triangle, the coordinates are (0, 0) and (2, 1)
![slope of diagonal line of first triangle = \frac{1 - 0}{2 - 0} = \frac{1}{2}](https://tex.z-dn.net/?f=slope%20of%20diagonal%20line%20of%20first%20%20triangle%20%3D%20%5Cfrac%7B1%20-%200%7D%7B2%20-%200%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
For the diagonal line of the large triangle, the coordinates are (2, 1) and (6, 3)
![slope of diagonal line of second triangle = \frac{3-1}{6-2} = \frac{2}{4} = \frac{1}{2}](https://tex.z-dn.net/?f=slope%20of%20diagonal%20line%20of%20second%20%20triangle%20%3D%20%5Cfrac%7B3-1%7D%7B6-2%7D%20%3D%20%5Cfrac%7B2%7D%7B4%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
