Anouk and Tessa are playing a game where a player flips a coin. If the coin lands on heads, the player receives 1 point. If the coin lands on tails, the player receives 2 points.
The expected value of a turn is 1.5 points.
Which of the following statements are true?
Choose all answers that apply:
The total number of points from 2 turns must be exactly 3 points.
It is possible for a player to get 1.5 points on a turn.
If they play a large number of turns, they should expect to average about 1.5 points per turn.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
