General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations using graphing
Step-by-step explanation:
To find the solution set of a systems of equations, the point where the 2 lines intersect would show the solution for the systems.
According to the graph given, both lines intersect each other at x = -1.
Therefore, our answer is B.
Answer:
For many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.
Step-by-step explanation:
1/1000 chance of winning.
This means that there is an 1/1000 probability of you earning $500.
1 - 1/1000 = 999/1000 chance of losing.
In this case, you earn nothing.
What is your average payoff from many tickets
Your average payoff from a ticket is 0.5. So for many(n) tickets, the average payoff is 0.5n, in which n is the number of tickets.
$416.14
478.68-210-89.55+38.50+65.74+125.61=408.58x.0185=7.56
So 408.58+7.56=416.14
