Missing part:

What is the probability that an international flight leaving the US is delayed in departing given that the flight is a transpacific flight?  

Answer:

P(D|P) = 0.50

Step-by-step explanation:

Given

P(D) = 0.26

P(P) = 0.50

P(D\ and\ P) = 0.13

The question illustrates conditional probability and it is represented as:

P(D|P)

This is then calculated as:

P(D|P) = \frac{P(D\ and\ P)}{P(D)}

So, we have:

P(D|P) = \frac{0.13}{0.26}

P(D|P) = 0.50

A plane flew 720 mi with a steady 30 mi/h tailwind. The pilot then returned to the starting point, flying against that same wind
NNADVOKAT [17]

Answer:

Plane's speed is 150 miles/hour

Step-by-step explanation:

Let the plane's airspeed be x

Speed of wind is 30 miles/hour

When a plane flew with the wind , Speed = (x+30)

So, the speed plain with wind on going = (x+30)

Since we are given that on returning plane fly against the wind .

So,When a plane flew against the wind , Speed = (x-30)

So, the speed plain against wind on returning = (x-30)

Distance = 720 miles .

Time = \frac{Distance}{Speed}

So, time on going  =\frac{720}{(x+30)}

Time on returning  =\frac{720}{(x-30)}

Now we are given that the total time for the whole trip (going + returning) = 10 hours.

So,  \frac{720}{(x+30)}+\frac{720}{(x-30)}=10

\frac{720x-21600+720x+21600}{(x+30)(x-30)}=10

720x-21600+720x+21600=10(x+30)(x-30)

720x+720x=10(x+30)(x-30)

1440x=10(x^2 -[30]^2)

144x=x^2 -900

x^2-144x -900=0

x^2-150x+6x -900=0

x(x-150)+6(x -150)=0

(x-150)(x+6)=0

x= 150,x= -6

So, the plane's speed is 150 miles/hour

Round 829 to the nearest tenth
Ainat [17]
829 rounded to the nearest tenth is 830

If the 9 would be a 4 or lower, then it would be 820, but in this case, it's a number larger than 5, so it would be 830.
