AveGali [126]

Answer:

Lorsque vous montez dans la voiture et sortez de l'aéroport, tournez à gauche. Lorsque vous arrivez à la bifurcation de la route, tournez à droite. Ensuite, vous continuerez à avancer. Vous devrez faire deux virages à gauche. À droite, vous verrez ma maison.

Step-by-step explanation: I had a similar project so I used mine as an example and I rewrote it. Hope this helps

Translation : When you first get in the car and exit the airport turn left. When you get to the fork in the road turn right. Then you will keep driving forward. You will have to make two left turns. To the right you will see my house.

PLEASE HELP GIVE BRANLIEST!!
Ipatiy [6.2K]

Answer:

1. 2/25

2. 4/15

Step-by-step explanation:

1. P(Y∩X)

Since  P(X) =2/3 , P(Y) =2/5 , and P(X|Y) =1/5, this is a conditional probability.

So  P(Y∩X) = P(Y)P(X|Y) = 2/5 × 1/5 = 2/25

2. P(Y)· P(X)

P(Y)· P(X) = 2/3 × 2/5 = 4/15

Complete the process of solving the equation. Fill in all missing terms and select all missing descriptions. Simplify any fracti
Sati [7]

Answer:

Step-by-step explanation:

WE willl solve the question for the following equation -8c-10+4c=-6c+8

1. Add 8c on both sides

8c-8c-10+4c = 8c-6c+8

-10+4c = 2c+8

2. Add 10 on both sides

10-10+4c = 10+2c+8

4c = 2c+18

3. Substract 2c on both sides

4c-2c = 2c+18-2c

2c =18

4. Divide both sides by 2

\frac{2c}{2}=\frac{18}{2}

c=2

Then, the equation is solved.
