Answer:
None of the given option corresponds to the answer.
Step-by-step explanation:
The parabola has its axis of symmetry parallel to the x-axis and is represented by the following expression:

Where:
,
- Components of the vertex location, dimensionless.
- Absolute distance of focus with respect to vertex, dimensionless.
The absolute distance is determined by following formula:

Where
is the horizontal component of focus with respect to origin.
If
,
and
, the absolute distance and the equation that represents the parabola is:



None of the given option corresponds to the answer.
The lottery's anticipated worth is $80.
Given that,
The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.
A) EV=125*.2+100*.3+50*.5=$80
The lottery's anticipated worth is $80.
The expected value is obtained by multiplying each result by its likelihood.
The expected value of the lottery is then calculated by adding up all of these.
This is what we have: ;;
125(0.2) + 100(0.3) + 50(0.5) (0.5)
= 25 + 30 + 25 = $80
B) This is the formula for variance is shown in figure :
So, we can calculate the variance as follows:
.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975
C) A risk-neutral person would pay $80 or less to play the lottery.
