Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 6x² - 2x + 2
f(-1) is x = -1
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-1) = 6(-1)² - 2(-1) + 2
- Exponents: f(-1) = 6(1) - 2(-1) + 2
- Multiply: f(-1) = 6 + 2 + 2
- Add: f(-1) = 8 + 2
- Add: f(-1) = 10
Answer:
1/6
Step-by-step explanation:
We know this because we have to first add up all of the coins, bringing us to 18. Then, to make the fraction of the probability of selecting a penny at random, we'd simply do 3/18. This simplified would be 1/6
