Answer:
0.5969 = 59.69% probability that it was a flight of airline A
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Left on time.
Event B: From airline A.
Probability of a flight leaving on time:
81% of 48%(airline A).
61% of 26%(airline B)
40% of 26%(airline C). So
Probability of leaving on time and being from airline A:
81% of 48%. So
What is the probability that it was a flight of airline A?
0.5969 = 59.69% probability that it was a flight of airline A
Answer:
27 minutes 44 blocks
Step-by-step explanation:
Add up the minutes for each driven block and non driven blocks. and add them up. Then add up the number of blocks he drove and there's your answer.When is say "add up the minutes for each driven block", I mean this ; For example when it said he drove from home which was 5 minutes then it said 2 blocks for every minute do 5 x 2 = 10, so 10 blocks for that.
When I say "add up the minutes for each non-driven block I mean this ; For example when it said he stopped at the bank and it took him 6 minutes it didn't say how many blocks it took for hime to get there so yeah. Just add them both together and that should be the answer.
Answer:
Yes, the zeros should be counted as significant.
Step-by-step explanation:
The zeros are significant because they show the place value of the number that is being rounded so they show how big the number is.
Answer:
78%
Step-by-step explanation:
Given the stem and leaf plot above, to find the median percentage for boys in the German test, first, write out the data set given in the stem and leaf diagram as follows:
40, 46, 46, 47, 69, 70, [78, 78,] 79, 82, 87, 90, 90, 95
The median value is the middle value in the data set. In this case, we have an even number of data set which are 14 in number.
The median for this data set would be the average of the 7th and 8th value = (78+78) ÷ 2 = 156/2 = 78
Median for boys = 78%
