The game that is  used for the scenario above in terms of fair play is  using a balloon. Here, the player will hit the balloon.

<h3>What is the scenario under the balloon game?</h3>

The rule of play are:

This is a classic game with simple rules which are:

  • Each player to hit the balloon up and it bonce into the air but when one should not allow it to touch the ground.,
  • Players would be tied together in twos and they will juggle a lot of balloon and it have to be more than 1 balloon with one of their hands tied to their back.

A scenario of the worksheet game whose expected value is 0 is given below:

Assume that it costs about $1 for a player to play the billon game and as such, if  the player hits a balloon, they will be given $3. what can you say. Can you say that it this game is fair or not? and who has the biggest advantage.

Solution

Note that a  game is ”fair” if the expected value is said to be 0. When a player is said to hits a balloon, their net profit often increase by $4.  So when the player do not hit a balloon, it drops to $1.

(4)(0.313) + (-1)(0.313)

= 0.939 approximately

Thus, the expected value is $0.939 which tells that the game is fair.

Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

x+2x+21=180

Combine like terms:

3x+21=180

Subtract 21 from both sides:

3x=159

Divide both sides by 3:

x=53

Therefore, the value of x is 53 degrees.

What are the roots of this equation 2x^2+7x-3=0
Ludmilka [50]

Step-by-step explanation:

2x^2+7x-3=0

by doing splitting the middle term we get/ <u>using quadratic eq we get-</u>

Let's solve your equation step-by-step.

2x2+7x−3=0

For this equation: a=2, b=7, c=-3

2x2+7x+−3=0

Step 1: Use quadratic formula with a=2, b=7, c=-3.

x=

−b±√b2−4ac

2a

x=

−(7)±√(7)2−4(2)(−3)

2(2)

x= −7±√73 /4

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73

Answer:

x= −7 4 + 1 4 √73 or x= −7 4 + −1 4 √73
