Answer:

13/25

Step-by-step explanation:

Firstly, we add the total number of persons together

That would be 20 + 6 + 17 + 7 = 50

The number of persons with brown eyes = 20

The number of persons with green eyes = 6

Probability of selecting someone with brown eyes = 20/50

Probability of selecting someone with green eyes = 6/50

The probability of selecting someone with brown or green eyes = Probability of selecting someone with brown eyes + Probability of selecting someone with green eyes = 20/50 + 6/50 = 26/50 = 13/25

What is the rule for finding the vertex of a formula in Standard form? Use that rule to
worty [1.4K]

The vertex is the minimum or the maximum point of the parabola.

<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

<em />

The standard form of a parabola is

f(x) = ax^2 +bx + c

The x coordinate of the parabola is calculated using:

x  =-\frac{b}{2a}

The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:

f(\frac{b}{2a}) = a(-\frac{b}{2a})^2 + b(-\frac{b}{2a}) + c

At the end of the calculation,

x and f(x) represent the horizontal and the vertical coordinates of the vertex.

Take for instance:

f(x) = 2x^2 + 4x - 9

The x-coordinate of the vertex is:

x = -\frac b{2a}

x = -\frac 4{2 \times 2}

x = -\frac 44

x=-1

The y-coordinate is:

f(x) = 2x^2 + 4x - 9

f(-1) =2 \times (-1)^2 + 4 \times -1 - 9

f(-1) =-11

So, the vertex of f(x) = 2x^2 + 4x - 9 is (-1,11)

See attachment for illustration of vertex of f(x) = 2x^2 + 4x - 9
