PLEASE HELP 2. CUBE GAME
In a carnival game, players win prizes by rolling a cube. The cube has one red side, one white side, one blue side and three green sides. This game costs $1 to play. If the cube stops with the red face up, the player receives a prize worth 50 cents. If it stops with the white face up, the player wins a prize worth $1.
When a blue face is showing, the prize is worth $1.50. If the cube shows a green face, the player wins
nothing.
a. Verify that the cube game is not mathematically fair by calculating the expected value.
b. Adjust the cost of playing the game to make it fair.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
