The adventure of

Jeff on Stuart's deserted island

During the beautiful summertime, near the marvelous continent of Africa, Jeff went alone on a trip with his helicopter. But then... BING BANG BOOM! He crashed! He soon realized he ended up on a deserted island...

Jeff desperately tried to get his helicopter to work again but sadly, it is broken. He needs to find out how to escape the island .

Start

He has no other choice, Jeff takes a deep breath and start exploring. He needs to walk around a big volcano and then, in the middle of it, he miraculously found a map! On that map, there was a plan of the island. The X on the map caught his attention. The x is guiding Jeff where to head to.

Jeff needs to find a way to escape the desert island. He’s looking around him but there’s nothing except vegetations. There is also no human trace! At this moment, he realizes that he was alone nowhere on an island. His heart start beating so fast that it was ringing to his hears. The panic takes the control of his body.

f(x)= -7(x-192)2 +6

f(x)= 7(x+6)2 +192

f(x)= -7(x-6)2 +192

(X, 0)

Knowing that it is a parabola, you need to find the rule of the quadratic fonction

Correct answer!

Good job! You find the good rule. Now you need to complete the next task to help Jeff find where's the misterious x on the map.

Oh no! You have the wrong answer try again to help Jeff.

Oh no! You probably made a mistake. Try again.

Incorrect answer!

Good job! You made it! Turn the page to see what's Jeff found.

Correct answer!

You made your way to Stuart's house! Now enter to see what is inside.

Congratulations!

There is a lock on the door! You need 3 digits to make the lock open. Solve the next problems to figure out the code in order to help Jeff get in.

Oh No!

P (A | B) = ?

P (A) = 4 P(B) = 5 P (A B) = 15

To find out what the first digit of the code is, solve this problem by finding what P (A | B) is!

Oh no! It looks like you made a mistake finding the first digit! Go back and try again, you can do it!

INCORRECT ANSWER!

Good job! You figured out what the first digit of the code is. Keep going to find out what the other digits are.

CORRECT ANSWER!

In order to find the second digit of the code, find the expectation (E.M) of the situation down below.

Oh no! It looks like you made a mistake finding the second digit! Go back and try again, you can do it!

INCORRECT ANSWER!

Good job! You figured out what the second digit of the code is. Keep going to find out what the last digit is.

CORRECT ANSWER!

You only have one last digit to find! All you have to do to figure it out is to solve this last problem!

Round your answer to the nearest unit

= 50$

= 20$

= 10$

= 5$

Here is a bag full of marbles.This bag contains 7 blue marbles, 5 red marbles and one yellow marble. How many green marbles is there,knowing that the E.M is 13$

Oh no! It looks like you made a mistake finding the last digit! Go back and try again, you can do it!

INCORRECT ANSWER!

Good job! You figured out what the last digit of the code is. The code to the house is 345!

CORRECT ANSWER!

Enter the house!

Congratulations! Jeff was able to unlock the door thanks to the code you found!

Jeff made it inside the house. He decided to take a look, hoping to find some food.

Click to button next to the phone to be able to use it.

In the kitchen, Jeff sees a phone.He gets a sense of hope, thinking he will be able to call someone that could help him...

Oh no! The phone is locked! You need to help Jeff unlock it in order to continue the quest.

DRAW THE CODE

LOCKED

Which one out of these two options is correct?

A: { 2, 4, 6 }B: { 1, 3, 6 } C: { 3, 4, 5, 6 }

A: { 2, 4, 6 } B: { 1, 3, 5 } C: { 4, 5, 6 }

Your goal: Extend each of the sets.

A: Get an even number B: Get an odd number C: Get a number higher than 3

Imagine a 6 sided dice. Here are 3 possible events:

Oh no! It looks like you made a mistake finding the right answer! Go back and try again, you can do it!

INCORRECT ANSWER!

Good job! You figured out what the last digit of the code is. The code to the house is 345!

CORRECT ANSWER!

1 3

A: { 2, 4, 6 } B: {1, 3, 5 } C : { 4, 5, 6}

Now, you have to select the Venn diagram that matches with your previous answer.

Oh no! It looks like you made a mistake finding the right answer! Go back and try again, you can do it!

Congratulations, your good job made you figure out the code, Jeff was able to unlock the phone with your help!

DRAW THE CODE

UNLOCKED

no signal

Congrats you helped Jeff to unlock Stuart's phone!

As he was about to give up, he raised his head and saw this enormous mountain. Peacefully, he realised that it was his only option. Jeff needed to climb the highest mountain on the island to caught signal on Stuart’s phone.

Jeff was so happy to unlock Stuart’s cellphone. He taught he could finally escape and returned home safely. As he was about to enter the phone and call for help, the “no signal” sign popped to his blue eyes. Desperately, they turn into this grayish color. He was profoundly mad and started to think he would never leave this prison island.

f(x) = -2 ( x + 2) ( x + 12)

f(x) = 2 ( x - 2) ( x - 12)

f(x) = -2 ( x - 2) ( x - 12)
