Answer:
The theoretical probability would be 25% or 1/4 because there are four sections but in the example the probability of a one being spun was 24%

Answer:
Her sister ate more cookies.
Step-by-step explanation:
If you convert 3/6 into a simplified fraction, it turns into half. Half of 12 is 6. Natalie ate 3 cookies. Therefore, her sister ate more.

<u>Pre-Algebra</u>
Order of Operations: BPEMDAS

<u>Algebra I</u>
Standard Form: ax² + bx + c = 0
Discriminant: b² - 4ac
- Positive - 2 solutions
- Equal to 0 - 1 solution
- Negative - No solutions/Imaginary
Step-by-step explanation:
<u>Step 1: Define</u>
x² - 6x - 10 = 0
<u>Step 2: Identify Variables</u>
<em>Compare quadratic.</em>
x² - 6x - 10 = 0 ↔ ax² + bx + c = 0
a = 1, b = -6, c = -10
<u>Step 3: Find Discriminant</u>
- Substitute in variables [Discriminant]: (-6)² - 4(1)(-10)
- [Discriminant] Evaluate exponents: 36 - 4(1)(-10)
- [Discriminant] Multiply: 36 + 40
- [Discriminant] Add: 76
This tells us that our quadratic has 2 real solutions.
