Answer:
C. A square is a rhombus
Step-by-step explanation:
A square fulfills all the requirements to become a rhombus:
A. All sides being equal.
B. The diagonals bisected at an angle of 90 degrees
3. ΔBDE ~ ΔBCF
4. BF/BC = BE/BD
5. 254/BC = 160/457
.. BC = 254*457/160 ≈ 725 units
Answer:
See explanation
Step-by-step explanation:
Given
randomly selecting a male
randomly selecting someone with blue eyes
Solving (a): Interpret P(M|B)
The above implies conditional probability
The interpretation is: the probability of selecting a male provided that a person with blue eyes has been selected
Solving (b): is (a) the same as P(B|M)
No, they are not the same.
The interpretation of P(B|M) is: the probability of selecting a person with blue eyes provided that a male has been selected
