Answer:
SAS
Step-by-step explanation:
Sas states that if two sides and the angle of one triangle are congruent to two sides and the include angle of another triangle, then these two triangle are congruent.
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.

Answer: The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
Step-by-step explanation:
The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
A. Eli's error was 3900-3867=33 kg.
B. A fairly small child would weigh about 33 kilograms.
C. Macy's percent error was .7/70=.01, or 1%. Eli's was 33/3900.0085, or .85%. Macy's percent error was larger, so Eli is more accurate.
