The answer is -40 because 1/2 of 4 is 2 and 1/2 of 5 is 2.5, 2•2.5=5. -2•-2•-2=-8. 5•-8=-40
Answer:
The score that separates the top 59% from the bottom 41% is 31.68
Step-by-step explanation:
<span>A: because a postulate is a statement that is accepted without proof.</span>
P(being delayed on M1) = 0.5 →P(NOT being delayed on M1) = 1-0.5 = 0.5
P(being delayed on M42)=0.75→P(NOT being delayed on M42) = 1-0.75= 0.25
P(NOT being delayed on M1) AND P(NOT being delayed on M42) = 0.5x0.25
→ 0.125 = 1/8
So, the chances he will not be delayed on his journey is 1/8
