Using the segment addition postulate, which is true?

Mathematics
1 answer:
Andrew [12]3 years ago
6 0

Answer: BC + CD = BD

Step-by-step explanation: The segment addition postulate tells you that when a segment is divided into two parts, the sum of the lengths of the first part of the divided segment and the second part of the divided segment will be equal to the length of the whole segment.

If point C divides segment BD into BC and CD, then the sum of those two segments will match the whole.

Givin P(X)=0.35, P(Y)=0.45, and P(Y|X)=0.25, what are P(X and Y) and P(X or Y)
schepotkina [342]

Answer:

P(Y|X)=\frac{P(Y\cap X)}{P(Y)} \\ P(Y\cap X) = P(Y)P(Y|X)  \\  = 0.45 \times 0.25 \\  \boxed{P(Y\cap X) =0.1125} \\ P(Y\cup X) = P(Y) + P( X) - P(Y\cap X) \\  = 0.45 + 0.35 - 0.1125 \\ \boxed{P(Y\cup X) =0.6875}
