Since a right triangle has special rules to it such that the hypotenuse squared equals the sum of the squares of the other 2 sides. In other words, if the hypotenuse = c, and the 2 smaller sides are a and b, then:
Solving for c (hypotenuse), we get:
Therefore c is the root of the square of the other sides. So by having root18, it's like saying:
Getting rid of the square root, so sides a and b must have their squares total 18:
the only squares < 18 are: 16 (4×4), 9 (3×3), 4 (2×2), and 1 (1×1)
of those above added in any order of two of them, only 16+4
I HOPE THAT IS ALONG THE LINE THAT WAS ASKED FOR!!! :-D
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.

Teehee gacha but look it up on quizlet or what the person above me said
If x=5, you need to plug in the value of x into the equation.
So: assuming that it's x^3 +x^2= 5^3+5^2
(5)*(5)*(5)= 125
(5)*(5)=25
125+25=150
So x^3+x^2, if x=5, is equal 150
