Answer:
Step-by-step explanation:
When we find a geometric sequence using the first and second terms, what we do is divide the second by the first to find a "common ratio," the number you multiply by to get to the next term.
In this case, we only have the second and fifth terms. From the second to the fifth term, we've multiplied by that common ratio three times.
What we can do is divide the fifth by the second and then take the <em>cube root</em> to find our common ratio.
Now we know we're multiplying by -4 each time, let's find the first term.
The opposite of multiplying by -4 would be dividing by -4. We work back from our second term -36 to find that the first term would be 9.
For each sucessive term, we then multiply by -4.
Our equation is
Using it's concept, it is found that the probability that the first three balls are drawn out of the box alternated in colour is of 0.1541 = 15.41%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Considering the situation described, the ways that alternate colored balls can be taken, and their probabilities, are given as follows:
- R(5/8) - W(3/9) - R(5/11).
- W(3/8) - R(5/10) - W(5/11).
Hence the probability is given by:

<h3>Conner work is correct. Jana work is wrong</h3>
<em><u>Solution:</u></em>
<em><u>Given that,</u></em>
<em><u>Conner and Jana are multiplying:</u></em>
Given Conner's work is:
We have to check if this work is correct
Yes, Conner work is correct
From given,
Use the following law of exponent
Therefore,
<em><u>Given Jana's work is:</u></em>
This is incorrect
The powers of same base has to be added. But here, powers are multiplied which is wrong
