429.99 + 0.34m or in slope intercept format y = 0.34x + 429.99
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
<h2 />
So just your normal equation.
We need to isolate x alone.
First lets write out our equation
3 +7x = 12
Lets do this step by step.
first subtract 3 from both sides.
3 + 7x = 12
-3 = -3 it cancels out on the left side and we solve on the right side.
*************
7x = 9
second we divide both sides by 7
7x = 9
÷7 = 7 we got the x alone and we just write 9/7 as our answer.
x = 9/7
Or as a decimal.
9/7 could be <span>1.28571428571429
</span>
Either will work.
x = 9/7
or
x = <span>1.28571428571429
</span>
Have a nice day. :)
