Answer:

5.5 x 10^-10

Step-by-step explanation:

There are 9 zeros descending from the decimal(so that's why its negative) then you count the five as a "number" and then it equals 10. Don't add the last five just one.

The expression 24y+36 represents the cost of a dozen eggs. Use factoring to write an expression that is equivalent to 24y+36 the
Genrish500 [490]

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 this in pictures and number of words
qaws [65]

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

David Barnes and his fiancée Valerie Shah are visiting Hawaii. At the Hawaiian Cultural Center in Honolulu, they are told that
balandron [24]

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:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}

C_{n,x} = \frac{n!}{x!(n-x)!}

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 N = 18.
  • 2 people will be chosen, hence n = 2.
  • David and Valerie corresponds to 2 people, hence k = 2.

The probability that both get picked is P(X = 2), hence:

P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}

P(X = 2) = h(2,18,2,2) = \frac{C_{2,2}C_{16,0}}{C_{18,2}} = 0.0065

0.0065 = 0.65% probability that both David and Valerie get picked for the Tahitian dance lesson.
