Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
f(x) = 8x² - 1
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(2) = 8(2)² - 1
- [Order of Operations] Simplify: f(2) = 31
The probability of two independant events <span>
and
</span><span> can be found by multiplying the individual probabilities like so:
</span>
For each individual probability we can find the answer via a simplfied representation:
For the first stone (orange) we have:
For the second stone (green) we have:
**(Notice that the total is still 18 since he put the first one back in the jar before drawing the second.)
So:
The Line Perpendicular to the reflective surface is the Normal.
