Answer:
Step-by-step explanation:
Let the number at B be x.
We know that distance between two points on the number line is the absolute value of the difference of numbers at those points.
Then distances representing the lengths of segments AB and BC are:
We are given the ratio of segments:
Substitute and solve for x:
- (x - 9)/(13 - x) = 2/3
- 3(x - 9) = 2(13 - x)
- 3x - 27 = 26 - 2x
- 3x + 2x = 26 + 27
- 5x = 53
- x = 53/5
- x = 10.6
A. X ~ N(66, 6.25)
b.


Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403
c. z= 0.524 and -0.524

1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4
Answer:
C
Step-by-step explanation:
If you draw a straight line through all the corresponding vertices, where the three vertices meet up at is the center of dilation, they all meat up at point C so C is the center of dilation.
