Answer:
Step-by-step explanation:
<u>If two secants are drawn from a point outside the circle, then the formula used for it will be:</u>
(FG + GH) × GH = (JI + IH) × IH
<u>Given that</u> IH = 29, JI = 23 and GH = 30
(FG + 30) × 30 = (23 + 29) × 29
(FG + 30) × 30 = 52 × 29
(FG + 30) × 30 = 1508
Divide both sides by 30
FG + 30 = 1508 / 30
FG + 30 = 50.3
Subtract 30 to both sides
FG = 50.3 - 30
FG = 20.3
Hope this helped!
<h3>~AH1807</h3>Answer:
89.01% probability that a flight arrives on time given that it departed on time.
Step-by-step explanation:
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: Departing on time
Event B: Arriving on time.
The probability that a flight departs and arrives on time is 0.81.
This means that
The probability that an airplane flight departs on time is 0.91.
This means that
Find the probability that a flight arrives on time given that it departed on time.
89.01% probability that a flight arrives on time given that it departed on time.
