The answer is -3 sorry if it’s wrong but I doubt that it is wrong
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.

Multiply 4/5 by 3 and 2/3 by 5
4/5=12/15
2/3=10/15
Answer: 2
Answer:
Step-by-step explanation:
f(x) = 5x - 9 and g(x) = x+9/5 are inverses of each other.

1. $85
2. $110
3.$135
4. $160
Explanation: $60 is a one time fee so only has to be used once in a formula.
Y:25x+60 X= the # of days so just multiply numbers of days by 25 then add the 60.
