A bag contains different colored candies. There are 50 candies in the bag, 28 are red, 10 are blue, 8 are green and 4 are yellow

Mrrafil [7]

Answer:

$\displaystyle \frac{54}{5405}$ .

Step-by-step explanation:

How many unique combinations are possible in total?

This question takes 5 objects randomly out of a bag of 50 objects. The order in which these objects come out doesn't matter. Therefore, the number of unique choices possible will the sames as the combination

$\displaystyle \left(50\atop 5\right) = 2,118,760$ .

How many out of that 2,118,760 combinations will satisfy the request?

Number of ways to choose 2 red candies out a batch of 28:

$\displaystyle \left( 28\atop 2\right) = 378$ .

Number of ways to choose 3 green candies out of a batch of 8:

$\displaystyle \left(8\atop 3\right)=56$ .

However, choosing two red candies out of a batch of 28 red candies does not influence the number of ways of choosing three green candies out of a batch of 8 green candies. The number of ways of choosing 2 red candies and 3 green candies will be the product of the two numbers of ways of choosing

$\displaystyle \left( 28\atop 2\right) \cdot \left(8\atop 3\right) = 378\times 56 = 21,168$ .

The probability that the 5 candies chosen out of the 50 contain 2 red and 3 green will be:

$\displaystyle \frac{21,168}{2,118,760} = \frac{54}{5405}$ .

Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in

pentagon [3]

Compound inequality combines multiple single inequalities.

The solution and interpretation of the inequality is:

<em /> $x > 50$ <em> and </em> $x < 150$ <em>. Ryan needs to consume more than 50 grams of carbohydrates, but less than 150 grams of carbohydrates.</em>

<em />

We have:

$110 < 2x + 10$ and $2x + 10< 310$

Solve for x in both inequalities

$110 < 2x + 10$

$110 -10 < 2x$

$100 < 2x$

Divide both sides by 2

$50 < x$

Rewrite as:

$x > 50$

Also, we have:

$2x + 10< 310$

$2x< 310 - 10$

$2x< 300$

Divide by 2

$x < 150$

So, the solutions to the inequalities are:

$x > 50$ and $x < 150$

This means that Ryan needs to consume more than 50 but less than 150 grams of carbohydrates.

Hence, (a) is correct

3. JK Rowling and R.L. Stine are both reading the Hunger Games. J.K. reads 35

Crank

Answer:

Part A:

For J.K. Rowling: 17.5pages/hour

For R.L. Stine: 15pages/hour

Part B:

J.K. Rowling will finish the book first.

Step-by-step explanation:

Part A:

The rate of change in this case represents how much changes a variable in a specific period of time. The variable is the amount of pages.

You have to calculate the amount of pages that J.K. Rowling and R.L. Stine read in one hour.

For J.K. Rowling, 35 pages every 2 hours can be written as:

If you divide 35/2 you can obtain the amount of pages in one hour:

17.5pages/hour (17.5 pages per hour)

For R.L. Stine, 45 pages every 3 hours can be written as:

If you divide 45/3 you can obtain the amount of pages in one hour:

15pages/hour (15 pages per hour)

Part B:

In order to calculate who will finish the hunger games first, you have to calculate the amount of time needed to finish the book.

For J.K. Rowling:

You have to multiply 355 pages by (because in one hour she reads 17.5 pages) to obtain the amount of hours

For R.L. Stine:

You have to multiply 355 pages by (because in one hour he reads 15 pages) to obtain the amount of hours

So, J.K. Rowling will finish the book first because she needs less time than R.L. Stine.
