Answer:
The probability that you made this call is 0.8639.
Explanation:
Parameter for you = λ1 = 2
⇒ β1 = 1 / λ1 = 1 / 2 = 0.5
Parameter for Janice = λ2 = 4
⇒ β2 = 1 / λ2 = 1 / 4 = 0.25
Probability that you made a for 0.5 hours or more:
Probability that Janice made a for 0.5 hours or more:
Overall probability that a call was made for 0.5 hours of more
= (0.7 x 0.3679) + (0.3 x 0.1353)
= 0.2981
Probability that you made the given call
= 0.7 x 0.3679 / 0.2981
= 0.8639
Answer:
48/80
Step-by-step explanation:
In order to get a denominator of 80, we need to turn the current denominator, 10, into 80. We do this by multiplying it by 8. We then have to multiply the top by 8 to keep it equal.
hope this helped :)
Distance formula = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(20,-4)...x1 = 20 and y1 = -4
(-4,3)...x2 = -4 and y2 = 3
now we sub
d = sqrt ((-4 - 20)^2 + (3 - (-4)^2)
d = sqrt ((-24^2) + (7^2))
d = sqrt (576 + 49)
d = sqrt 625
d = 25 <==
Answer:
20:50
Step-by-step explanation:
2:5
They got 20 by multiplying 2 by 10 so we multiply 5 by 10 which is 50
Step-by-step explanation:
????
if every adult couple (2 people, 1 man, 1 woman) has 3 or more children, then there are automatically more children than adults.
it is absolutely possible that there are more boys than girls, as it is also possible that there are more girls than boys.
after all, this is a 50% chance, and it is very unlikely that a 50% chance has a true 50/50 split in real events or experiments.
like when flipping a coin. heads and tails will almost never be mathematically precisely split. there will be more heads or more tails.
this might be due to imbalances in the flipping process or in the coin balance itself. or, if truly balanced, it will achieve the full 50/50 split after infinite attempts.
