It increases then falls, so it is approximately a bell shaped curve.
Answer:
Step-by-step explanation:
1 dozen eggs = 12 eggs
cost of one dozen = 24y+36
= 12( 2y+3)
cost of one egg = 2y+3
Answer: Tom's solution is incorrect.
Step-by-step explanation:
When you add 3/6 + 1/2 it equals ?.
3 + 1 = ?
6 + 2 = ?
We must have common denominators to do this problem.
So we must have 6 as our common denominator.
So 2 x 3 = 6. But we have to do the same to the Numerator.
So 1 x 3 = 3.
Now our problem is 3/6 + 3/6 = ?
3 + 3 = 6/6. Or 1
1 does not equal 4/12 or 1/3. So it makes it Incorrect.
What you should say:
Tom is incorrect, it is because 3/6 + 1/2 = 1, 1 does not equal 4/12 or 1/3. So, it makes it reasonable for the correct answer to be Incorrect
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.
