Answer:
The probability of winning a jackpot is
The probability of winning the pick 5 game is
The earning of the lottery organisation if the game were to be runed for no profit is $10 000
Step-by-step explanation:
From the question
The sample size is n= 37
The number of selection is
Now the number of way by which these five selection can be made is mathematically represented as
Now substituting values
Now the probability of winning a jackpot from any of the way of selecting 5 whole number from 37 is mathematically evaluated as
Now the number of ways of selecting 5 whole number from 0 to 9 with repetition is mathematically evaluated as
Now the probability of winning the game is
We are told that for a $1 ticket that the pick 5 game returns $50 , 000
Generally the expected value is mathematically represented as
In this question the expected value is $1
So
So
$10 000

Answer:
y = 1/6 x^2 + 8/3 x + 49/6
Step-by-step explanation:
This is a parabola which opens upwards.
The distance of a point (x, y) from the focus is
√[(x - -8)^2 + (y - -1)^2] and
the distance of the point from the line y = -4
= y - -4
These distances are equal for a parabola so:
√[(x - -8)^2 + (y - -1)^2] = y + 4
Squaring both sides:
(x + 8)^2 + (y + 1)^2 = (y + 4)^2
x^2 + 16x + 64 + y^2 + 2y + 1 = y^2 + 8y + 16
x^2 + 16x + 64 + 1 - 16 = 8y - 2y
6y = x^2 + 16x + 49
y = 1/6 x^2 + 8/3 x + 49/6 is the equation of the parabola.
