Point E is given by 
Now plot point E.
Answer:
The correct option is E) About 1 in a million.
Step-by-step explanation:
Consider the provided information.
It is given that one in a hundred million people is a genius.
Let G represents the Genius and Q represents the quirky.
We need to find the probability that someone is acting quirky- what is the probability that they are a genius.
The probability that person is quirky is: 
The probability of
Hence, the required probability is:



Which is near about 1 in a million.
Hence, the correct option is E) About 1 in a million.
4(k-2) when it says 2 less than it means you are subtracting from the constant and 4 times means you are multiplying the whole equation with 4.
Since the parabola passes by the center its equation is:
y = ax². But it opens downward, that means the coefficient a is negative.
Then the equation becomes:
y = - ax², with x = 0 as its axis of symmetry.
We are given that the height is 84 ft when the opening downward is 42 ft.
That means to the (height) y, corresponds x =+21 & x=-21 (due to symmetry).
In order to calculate a let's plug y & x with their related values:
y = - ax²
84 = - a(21)²
84 = - a(441) and a = - 84/441 ↔ a = - 4/21
And the final equation is : y = -4/21. x²
