Answer:

Hence, the probability is:

0.82

Step-by-step explanation:

Let A denote the event that the flight departs on time.

Let B denote the event that the flight arrives on schedule.

Also, A∩B denotes the event that the flight that departs on time also arrives on schedule.

Let P denotes the probability of an event.

We are asked to find:

                              P(B|A)

We know that:

P(B|A)=\dfrac{P(A\bigcap B)}{P(A)}

Hence, we have:

P(A)=0.83 x.

P(A∩B)=0.68 x.

where x are the total number of flights.

Hence,

P(B|A)=\dfrac{0.68x}{0.83x}\\\\P(B|A)=0.82

Hence,  the probability that a flight that departs on schedule also arrives on schedule is:

                                     0.82

Solve for c <br><br> a= b+c/d
castortr0y [4]
B+c/d=a  subtract b from both sides

c/d=a-b multiply both sides by d

c=d(a-b) or if you prefer

c=ad-bd

Note: if you meant a=(b+c)/d, multiply both sides by d

b+c=ad  subtract b from both sides

c=ad-b

Answer:

The answer to your question is distance = 3500000 km

Step-by-step explanation:

Data

Scale  1 : 500000

7 cm

Process

1.- To solve this problem use direct proportions or rule of three.

                          1 : 500 000 :: 7 : x

2.- Multiply the middle numbers and the result divide it by the edge.

                x = (7 x 500000) / 1

Simplification

                x = 3500000 km
