Help pleaseeeee!!!!!!!

A bag contains 9 red, 8 orange, and 6 green jelly beans. What is the probability of reaching into the bag and randomly withdrawi

Olenka [21]

Answer:

63/12167

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Total number of jellybeans = 9+8+6 = 23

Assuming the withdrawal is done with replacement

Probability (of withdrawing 17 jellybeans with 7 red, 7 orange and 3 green) = 7/23 × 7/23 × 3/23 = 63/12167

Leona [35]

Answer:

The purpose of statistical inference is to provide information about the population based upon information contained in the sample.

Step-by-step explanation:

population based upon information contained in the sample

Step-by-step explanation:

Statistical inference is the process of using data analytics to deduce proprierties of an underlying probability distribution.

For example, if I want to know the percentage of Buffalo Bills fans that are from Canada. There is no way I can ask this question to every Bills fan(every Bills fan is the population). What I can do, for example, is go to a game and ask some of the fans there, that is, of a sample.

Need help filling in the blanks: selling price using markup.

Xelga [282]

Answer:

Refer to the explanation.

Step-by-step explanation:

Let's take each one at a time.

1.

To solve for the complement, we simply subtract our markup rate by 100%.

100% - 30% = 70%

Now to solve for the selling price, we use the formula

$SellingPrice=\dfrac{Cost}{ComplementOfMarkupRate}$

$SellingPrice=\dfrac{86.74}{0.70}$

Selling Price = $123.91

2.

We do the same process with the first number.

100% - 40% = 60%

$SellingPrice=\dfrac{Cost}{ComplementOfMarkupRate}$

$SellingPrice=\dfrac{220.00}{0.60}$

SellingPrice = $366.67

3.

The same as the first two.

100% - 20% = 80%

$SellingPrice=\dfrac{Cost}{ComplementOfMarkupRate}$

$SellingPrice=\dfrac{89.50}{0.80}$

SellingPrice = $111.88

4.

Now to solve for the markup rate, we use the formula:

$MarkupRate=\dfrac{Markup}{SelingPrice}$

In this case we first need to find the markup. The markup is the difference between the selling price and the cost.

Selling Price = $235.28

Cost = $199.99

Markup = $235.28 - $199.99

Markup = $35.29

Now the we know our markup, we can then solve for the markup rate using the formula.

$MarkupRate=\dfrac{Markup}{SelingPrice}$

$MarkupRate=\dfrac{35.29}{235.28}$

MarkupRate = 0.1499 x 100 = 14.99% or 15%

5.

Now for the last one, we need to find for the cost. Let's use the selling price formula to find for the cost.

$SellingPrice=\dfrac{Cost}{ComplementOfMarkupRate}$

Selling Price = $30.77

Complement = 65% or 0.65

This will then give us.

$30.77=\dfrac{Cost}{0.65}$

We multiple both sides of the equation by 0.65 to leave our cost alone.

30.77 x 0.65 = Cost

Cost = $20

Help please!!! thanks

Rom4ik [11]

Answer:

27

Step-by-step explanation:

first we can simplify by dividing by r

$\frac{9 {r}^{2} }{r} = \frac{9 \times r \times r}{r} = 9 \times r \times 1 = 9r$

the r on the bottom of the fraction will cancel out one of the r's on top, this happens because anything divided by itself is 1, thus r divided by r is 1

finally we can evaluate when r =3,

9r = 9(3) = 27
