Answer:
62.5%
Step-by-step explanation:
To find percentage of win, we simply need to find the number of games won and divide it by the total number of games played. Then we will multiply that answer by 100 (to get percentage).
So,
Number of games won = 15
Total number of games = 15 + 9 = 24
Percentage of Win =
Answer is 62.5%

Hello!
Standard form of a quadratic:
From our Equation:
- a = 1/2
- b = -2
- c = 0
There are several values that are needed to drawing a parabola:
- y - intercept
- Axis of Symmetry (AOS)
- Vertex
- x - intercepts
Standard form of a quadratic:
The y-intercept is the "c" value. Given that our equation has a "c" value of 0, the y -intercept is 0.
<h2>Axis of Symmetry</h2>A parabola is always symmetrical vertically. The line in which the fold happens is the Axis of Symmetry.
To calculate the AOS, we use the formula , from the values of the equation.
Calculate
The Axis of Symmetry is a vertical line, so the AOS is the line x = 2.
<h2>Vertex</h2>The vertex is the highest or lowest point on the graph of a parabola. It resides on the AOS of the graph.
To calculate the vertex, we simply have to find the y-value, given that we have the x-value from the AOS. We can find the y-value by plugging in the AOS for x in the original equation.
Calculate
The y-value is -2. The vertex is (2, -2).
<h2>X-intercepts</h2>The x-intercepts are the points where the graph intersects the x-axis (y = 0).
Solve by Factoring
The roots are (0,0) and (4,0).
<h2>Graph</h2>Now we just draw the y-intercept, vertex, AOS, and the x-intercepts, and draw a curved line between them.

<h2>Domain Restrictions</h2>The Domain (x-values) are being restricted to all x-values that are greater than or equal to -2 and less than 4.
That means we remove the parts of the line that don't belong in that domain.
