Answer:
-$13.5
Step-by-step explanation:
Let x be a random variable of a count of player gain.
- We are told that if the die shows 3, the player wins $45.
- there is a charge of $9 to play the game
If he wins, he gains; 45 - 9 = $36
If he looses, he has a net gain which is a loss = -$9
Thus, the x-values are; (36, -9)
Probability of getting a 3 which is a win is P(X) = 1/6 since there are 6 numbers on the dice and probability of getting any other number is P(X) = 5/6
Thus;
E(X) = Σ(x•P(X)) = (1/6)(36) + (5/6)(-9)
E(X) = (1/6)(36 - (5 × 9))
E(X) = (1/6)(36 - 45)
E(X) = -9/6 = -3/2
E(X) = -3/2
This represents -3/2 of $9 = -(3/2) × 9 = - 27/2 = -$13.5
Y=4 or -4

Answer: $3.42
Step-by-step explanation:
Interest= Principal x Rate x Time
From the question, Principal =$2,150
Rate= 22.9% annually means per year, to calculate the monthly rate, we divide by 12
=22.9%/12 = 1.908% per month
Time = one month, meaning one month out of 12months = 1/12
I is therefore: 2150 x 1.908% x 1/12
= 2150 × 0.01908 x 0.0833
=$3.42
I hope this is clear, please mark as brainliest answer.
