Answer:
$ -11.61
Step-by-step explanation:
The expected value in this case would be the subtraction between the probability that the draw will win for its value (the prize + value of the ticket) and the value of the ticket for the probability of not winning the draw, thus:
(1/810) * (1100 + 13) - (809/810) * (13)
1,374 -12,984 = -11.61
which means that the expected value is $ -11.61
The equation of parabola is
.
The canonical equation of parabola is
and this parabola has branches that go in positive direction of x-axis.
Since in your equation x is changed to y and y to x, then the <span>branches of the parabola go in positive y-axis direction, the vertex is placed at the origin.
