A) Answer: x>2
Step by Step: •-2x-10<-14
•-2x-10(+10)<-14(+10)
•-2x<-4 -divide each side by -2x
•x>2(since you divided by a negative, switch the sign)
b) Answer: x<-7
Step by Step: •x+4/3 < -1
•multiply each side by the denominator (3)
•x+4(-4)<-3(-4) subtract
•x<7
Here are the graphs!!
Answer:
This is B because as we can see the X axis increases in value to y decreases making it negetive
Let be the random variable representing the winnings you get for playing the game. Then
First thing to do is determine the probability of each of the above events. You roll two dice, which offers 6 * 6 = 36 possible outcomes. You find the probability of the above events by dividing the number of ways those events can occur by 36.
- The sum is odd if one die is even and the other is odd. This can happen 2 * 3 * 3 = 18 ways. (3 ways to roll even with the first die, 3 ways to roll odd for the die, then multiply by 2 to count odd/even rolls)
- The sum is 4 if you roll (1, 3), (2, 2), or (3, 1), and the sum is 8 if you roll (2, 6), (3, 5), (4, 4), (5, 3), or (6, 2). 8 ways.
- The sum is 2 if you roll (1, 1), and the sum is 12 if you roll (6, 6). 2 ways.
- There are 36 total possible rolls, from which you subtract the 18 that yield a sum that is odd and the other 10 listed above, leaving 8 ways to win nothing.
So the probability mass function for this game is
The expected value of playing the game is then
or about $7.89.
B is the answer I know because I took the test
The given equation is
First, we add 19 on each side
Then, we divide the equation by 3
<h2>Hence, z is equal to 64.</h2>
