<em>Question:</em>
<em>Which of the following is NOT a formula for determining complementary probability?</em>
<em>A. P(outcome) = 1- P(-outcome)</em>
<em>B. P(outcome) - P(-outcome) = 1</em>
<em>C. P(outcome) + P(-outcome) =1</em>
<em>D. P(-outcome) = 1 - P(outcome)</em>
<em></em>
Answer:
Step-by-step explanation:
Required
Determine which option is not a formula of complementary probabilities
From the list of given options, the complementary probabilities are P(outcome) and P(-outcome)
In probability;
--- Equation 1
Subtract P(outcome) from both sides
------ Equation 2
Subtract P(-outcome) from both sides of equation 1
Equation 1, 2 and 3 represents options A, C and D
While option B is out of place
<em>Hence, option B is not a formula of complementary probability</em>
The standard form of the parabola is x = -4/3y² -40/3y -103/3
What is parabola?
A parabola is an approximately U-shaped, mirror-symmetrical planar curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. One way to describe a parabola is with a point and a line.
x = -4/3(y +5)² -1
Solve for x.
x = (4y² +40y +103)/(-3)
x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US
__
Taking our clues from the graph*, we can write the vertex form equation as ...
x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places
____
* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...
x = a(y -(-5))² +(-1) = a(y +5)² -1
The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.
