(a) ANSWER: S = 131 degrees. So the measure of the supplementary angle for 49 degrees is 131 degrees which is the second entry on your list of possible answers.

(b) A complementary angle is 90 degrees. For you to get the complement of 42 degrees, subtract 42 degrees from 90 degrees. ANSWER: C = 48 degrees

(Sorry if it’s wrong)

The bakers at healthy bakery can make 330 bagels in 5 hours. How many bagels can they bake in 13 hours? what was that rate per h

earnstyle [38]

5 hours = 330 bagels to find how many in 1 hours divide by 5 1 hour = 66 bagels then do 66 x 13 = 858 so in 13 hours they bake 858 bagels

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.
