The answer is |10| absolute value CANT be negative so it is 10
Answer:
,
Step-by-step explanation:
The total area of the pool and the walkway is:
The roots of the second-order polynomial is:
and
The only possible root is:
The other dimension of the pool is:
Using the hypergeometric distribution, it is found that there is a 0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.
The people are chosen without replacement from the sample, hence the <em>hypergeometric distribution </em>is used to solve this question.
<h3>What is the
hypergeometric distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
In this problem:
- There is a total of 18 people, hence .
- 2 people will be chosen, hence .
- David and Valerie corresponds to 2 people, hence .
The probability that both get picked is P(X = 2), hence:
0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.

As time time starts at zero, he is at home. As time goes on, he travels to a given location, which is why his distance increases. He then stays there for a while which is why the time continues to go on but his distance doesn't change. He then rides home quickly.
Answer:
341
Step-by-step explanation:
- Plug the value of b in:
- 3(25) = 3 × 25 = 75
- Plug 75 in:
- = 75 ÷ 5 = 15
- Plug 15 in: 356 - 15
- 356 - 15 = 341
I hope this helps!
