Answer:
<u></u>
Explanation:
The table that shows the results and the question (taken from similar question) are:
<em>Number Showing Frequency</em>
<em>on Top Face</em>
<em> 1 0</em>
<em> 2 3</em>
<em> 3 3</em>
<em> 4 6</em>
<em> 5 3</em>
<em> 6 5</em>
<em />
<em>Based on these results, what is the experimental probability that the next time the number cube is rolled it will land with 5 or 6 showing on the top face? </em>
<h2 /><h2>Solution</h2><h2 />
The frequencies of each event recorded for a particular experience are named<em> experimental probabilities</em> and, in general, differ from the theoretical probabilities.
Experimental probabilities, for instance, when compared with the theoretical probabilities, may show a bias, like a loaded (unfair) die.
<em>The experimental probability that the next time the number cube is rolled it will land with 5 or 6 showing on the top face </em>is equal to the number of times the die showed a 5 or a 6 on the top face (the frequencies) divided by the number of times the experiment was performed:
- Frequency of 5 on top face: 3
- Frequency of 6 on top face: 5
====
8
- Number of times the experiment was performed: 0 + 3 + 3 + 6 + 3 + 5 = 20
Probability = 8 / 20 = 2 / 5 = 0.4 ← answer

Step-by-step explanation:
F(x) = -5x^2 - x + 20;
f(3) = -5*3^2 - 3 + 20 = -5*9 - 3 + 20 = -45 - 3 + 20 = -28;
The answer Is 4! Good luck
