A bag contains 88 red, 66 orange, and 99 green jellybeans. What is the probability of reaching into the bag and randomly withdrawing 1212 jellybeans such that the number of red ones is 22, the number of orange ones is 44, and the number of green ones is 66? Express your answer as a fraction or a decimal number rounded to four decimal places.

Answers

Answer 1

Answer:

P ( 2 R , 4 O , 6 G ) = 0.0261

Step-by-step explanation:

Given:

- Red beans = 8

- Orange beans = 6

- Green beans = 9

Find:

What is the probability of reaching into the bag and randomly withdrawing 12 jellybeans such that the number of red ones is 2, the number of orange ones is 4, and the number of green ones is 6?

Solution:

- The question requires the number of selection of 12 jellybeans we can make from total available such that out of those 12 we choose 2 Red, 4 Orange and 6 Green.

- For selection we will use the combinations. So to choose 2 Red from 8; Choose 4 Orange from 6 and 6 green from 9 available. The number of possible outcomes with such condition is:

          Outcomes ( 2 R , 4 O , 6 G ) = 8C2 * 6C4 * 9C6

                                                         = 28*15*84

                                                         = 35280

- The total number of outcomes if we randomly select 12 beans irrespective how many of each color we select from available 23 we have:

          Outcomes ( Select 12 from 23 ) = 23C12

                                                               = 1352078

- Hence, the probability for the case is given by:

P ( 2 R , 4 O , 6 G ) = Outcomes ( 2 R , 4 O , 6 G ) / Outcomes ( Select 12 from 23 )

P ( 2 R , 4 O , 6 G ) = 35280 / 1352078 = 0.0261

Answers

Answer: the solutions of the equation are

x = - 1

x = 8

x = 9

Step-by-step explanation:

The given cubic equation is expressed as

x³ - 16x² + 55x + 72 = 0

The first step is to test for any value of x that satisfies the equation when

x³ - 16x² + 55x + 72 = 0

Assuming x = - 1, then

- 1³ - 16(-1)³ + 55(-1) + 72 = 0

- 1 - 16 - 55 + 72 = 0

0 = 0

It means that x + 1 is a factor.

To determine the other factors, we would apply the long division method. The steps are shown in the attached photo. Looking at the photo, we would factorize the quadratic equation which is expressed as

x² - 17x + 72 = 0

x² - 9x - 8x + 72 = 0

x(x - 9) - 8(x - 9) = 0

(x - 9)(x - 8) = 0

Suppose that a brand of lightbulb lasts on average 1730 hours with a standard deviation of 257 hours. Assume the life of the lightbulb is normally distributed. Calculate the probability that a particular bulb will last from 1689 to 2267 hours?

Answers

Answer:

P [  1689  ≤   X  ≤  2267 ]  = 54,88 %

Step-by-step explanation:

Normal Distribution

Mean        μ₀  =  1730

Standard Deviation      σ  = 257

We need to calculate  z scores for the values   1689     and      2267

We apply formula for z scores

z =  ( X -  μ₀ ) /σ

X = 1689     then

z = (1689 - 1730)/ 257      ⇒ z = - 41 / 257

z  = -  0.1595

And from z table we get  for  z =  - 0,1595

We have to interpolate

        - 0,15          0,4364

        - 0,16          0,4325

Δ  =   0.01           0.0039

0,1595  -  0,15  =  0.0095

By rule of three

0,01                  0,0039

0,0095                 x ??      x  =  0.0037

And    0,4364  -  0.0037  = 0,4327

Then    P [ X ≤ 1689 ]  =  0.4327     or    P [ X ≤ 1689 ]  = 43,27 %

And for the upper limit  2267  z  score will be

z  =  ( X - 1730 ) / 257       ⇒  z =  537 / 257

z  =  2.0894

Now from z table   we find  for score   2.0894

We interpolate and assume  0.9815

P [ X ≤ 2267 ]  =  0,9815

Ths vale already contains th value of   P [ X ≤ 1689 ]  =  0.4327

Then we subtract  to get    0,9815  -  0,4327   = 0,5488

Finally

P [ 1689  ≤   X  ≤  2267 ]  =  0,5488  or  P [  1689  ≤   X  ≤  2267 ]  = 54,88 %

Mary Ward recently leased a new convertible. The $1600 due at signing inc the title and license fee. Her monthly lease payments are $700 per mont leasing company allows 12,000 miles per year with a $0.12 per mile overage charge. If the total lease cost is $26,800, for how many months does the lease ludes . The last?

Answers

This calculation shows that Mary Ward's lease term is 36 months.

The question is asking us to find out for how many months Mary Ward's car lease lasts. To do so, we need to calculate the total monthly payments and then subtract the initial $1600 fee to find the total cost of the monthly payments alone. Then, we divide this amount by the monthly lease payment to determine the total number of months for the lease duration.

First, we deduct the initial fee from the total lease cost:

Total lease cost - Initial fee = Total of monthly payments

$26,800 - $1,600 = $25,200

Next, we divide this result by the monthly lease payment to find out the number of months:

$25,200 / $700 = 36 months

Therefore, the lease agreement lasts for 36 months, which is typically the term for most vehicle leases.

The average wall thickness of 25 panes of glass is 4.05 mm. The standard deviation of the thickness of the 25 panes is measured to be 0.08 mm. What is the 90% confidence interval of the mean of wall thickness

Answers

Answer:

u => 4,028

Step-by-step explanation:

To find the answer, we have the following formula:

u => m - t (alpha, n-1) * [sd / (n) ^ (1/2)]

where m is the mean.

where sd is the standard deviation.

where n is the sample size.

t is a parameter that depends on the confidence interval and the sample size.

alpha = 1 - ci

ci = 90% = 0.9

Therefore, alpha = 1 - 0.9 = 0.1.

n - 1 = 25 - 1 = 24

So it would come being t (0.1, 24), if we look in the table, which I will attach the value of t is equal to 1.318.

We know the rest of the values, m = 4.05; sd = 0.08; n = 25

u => 4.05 - 1,318 * [0.08 / (25) ^ (1/2)]

u => 4.028

Which means that the interval with a 90% confidence of the wall thickness measurement is:

u => 4.028

A Chinese restaurant uses about 15 exponent 2 appearance of chopsticks each day the manager wants to order a 30-day supply of chopsticks chopsticks come in boxes of 750. How many boxes should the manager order

Answers

Answer:

9 boxes of chopsticks.

Step-by-step explanation:

The first thing is to calculate the number of chopsticks spent in a day, the problem tells us that they are 15 ^ 2 = 15 * 15 = 225 chopsticks daily.

To calculate the number of chopsticks in 30 days, it is to calculate the previous amount by 30:

225 * 30 = 6750 chopsticks spent in one month.

To know how many boxes you should order is to divide the total number of chopsticks in a month and the number of chopsticks that a box brings that are 750:

6750/750 = 9 boxes of chopsticks.

Therefore you should order exactly 9 boxes of chopsticks for the restaurant's need.

Step-by-step explanation:

According to the flaring, the triangle expressed in the figure is formed.

Now we have a vector A and vector B, whose components are Ax, Ay and Bx and By respectively.

To calculate these components you must use the following formulas:

Ax = A * cos [angle a] = 32 * cos 37 ° = 25.6

Ay = A * sin [angle a] = 32 * sin 37 ° = 19.3

Bx = B * cos [angle a] = 21 * cos 23 ° = 19.3

By = B * sin [angle b] = 21 * sin 23 ° = - 8.2

In the figure it can be seen that vector B is the result of vector A and vector C

Thus:

B = A + C

reorganizing is:

C = B - A

Now to calculate Cx and Cy, we will do it with the previously calculated components:

Cx = Bx - Ax = 19.3 - 25.6 = -6.3

Cy = By - Ay = -8.2 - 19.3 = -27.5

Now to calculate the value of vector C, we apply the following formula:

C ^ 2 = Cx ^ 2 + Cy ^ 2

Rearranging:

C = (Cx ^ 2 + Cy ^ 2) ^ (1/2)

C = [(-6.3 ^ 2) + (27.5 ^ 2)] ^ (1/2) = 28.2

Then the distance would be 28.2 meters.

Answers

Answer:

85%

Step-by-step explanation:

The probability of finding our satisfactory service in the three visits in a row would be the multiplication of the probability of each event.

The event is always the same. 95% of the service will be satisfactory. That is a probability of 95/100

Then the final probability would be:

Answers

Answer:

[tex]x<120[/tex]

Step-by-step explanation:

We have been given an inequality [tex]-30<\frac{x}{-4}[/tex]. We are asked to solve the given inequality.

To solve for x, we will multiply both sides of inequality by negative 4. When we multiply or divide both sides of an inequality, the inequality sign reverses.

[tex]-30\cdot (-4)>\frac{x}{-4}\cdot (-4)[/tex]

[tex]120>x[/tex]

This means that 120 is greater than x or x is less than 120.

[tex]x<120[/tex]

Therefore, our required inequality would be [tex]x<120[/tex].

Final answer:

The solution to the inequality -30 < x / -4 is found by multiplying both sides by -4, which reverses the inequality sign, resulting in the solution x < 120. This demonstrates the manipulation of inequalities, particularly when involving negative multipliers.

Explanation:

The correct interpretation of this question is solving the inequality -30 < x / -4. To solve this inequality, we firstly multiply both sides by -4, remembering that multiplying or dividing by a negative number reverses the inequality sign. Thus, the inequality becomes 120 > x, which means x must be less than 120 for the inequality to hold true.

Therefore, the solution to the given inequality is x < 120. This highlights the importance of carefully handling inequalities, especially when multiplying or dividing by negative numbers, as it requires reversing the inequality sign to maintain the accurate relationship between both sides.

A map is shown with a scale drawing of 1 inch = 15 miles,nicloe measured the distance to the next town as 3 inches. How many miles does she have to travel to get to the next town

Answers

Answer: There are 45 miles that she have to travel to get to the next down.

Step-by-step explanation:

Since we have given that

1 inch = 15 miles

If there are given 3 inches.

We need to find the number of miles she have to travel to get to travel to get to the next town.

So, it becomes,

[tex]\dfrac{1}{15}=\dfrac{3}{x}\\\\x=15\times 3\\\\x=45\ miles[/tex]

Hence, there are 45 miles that she have to travel to get to the next down.

A group of equations that have a common intersection point is called

Answers

Answer:

system of equations i think

Step-by-step explanation:

A group of equations that have a common intersection point is called: system of equations.

A system of equations can be defined as an algebraic equation of the first order with two (2) variables and each of its term having an exponent of one (1).

Generally, a system of equations in two (2) variables must have at least two (2) solution.

This ultimately implies that, a system of equations must have a common intersection point.

In Mathematics, an example of a system of equations include the following:

[tex]2x + 4y = 8[/tex]    ....equation 1.[tex]2x - 8y = 20[/tex]   ....equation 2.

Additionally, the above system of equations can easily be solved by using an elimination method.

In conclusion, a solution of the group of equations is an ordered pair that satisfies all the equations in a system of equations.

Law of Sines and the Ambiguous Case.
m < A = 34*
a = 9
c = 6
How many distinct triangles can be drawn given these measurements?

Answers

Answer:

One

Step-by-step explanation:

9/sin(34) = 6/sinC

sinC = 0.372795269

C = 21.9, 158.1

Since 158.1 + 34 = 192.1 > 180

Only one triangle can be formed with angle 21.9° at C

Sin(146° + ∠B) cannot exceed 1, there is no solution for b that satisfies the triangle inequality. Therefore, no distinct triangle can be drawn with the given measurements.

To determine the number of distinct triangles that can be drawn with the given measurements using the Law of Sines, we need to consider the Ambiguous Case (also known as the SSA case or the "side-side-angle" case).

The Law of Sines states:

sin(A) / a = sin(B) / b = sin(C) / c

Given:

m∠A = 34°

a = 9

c = 6

We want to find ∠B and side b.

First, find ∠B using the Law of Sines:

sin(B) / b = sin(A) / a

sin(B) / b = sin(34°) / 9

Now, find sin(34°):

sin(34°) ≈ 0.5592

Now, solve for sin(B) by multiplying both sides by b:

sin(B) = (0.5592 * b)

Next, find ∠C:

Since the sum of angles in a triangle is 180°:

∠C = 180° - ∠A - ∠B

∠C = 180° - 34° - ∠B

Determine the value of side b:

Using the Law of Sines again, we have:

sin(C) / b = sin(A) / a

sin(C) / b = sin(34°) / 9

Find sin(C):

sin(C) = sin(180° - 34° - ∠B)

We can now use the fact that sin(C) = sin(180° - angle) to find sin(C):

sin(C) = sin(180° - 34° - ∠B) = sin(146° + ∠B)

Now, solve for b by multiplying both sides by b:

sin(146° + ∠B) = (sin(34°) / 9) * b

Since sin(146° + ∠B) cannot be greater than 1 (the maximum value for sine), the number of distinct triangles will depend on the possible values of b.

In this case, we have sin(146° + ∠B) = (sin(34°) / 9) * b, and since sin(34°) ≈ 0.5592, the maximum value for (sin(34°) / 9) * b is approximately 0.5592 * 6 ≈ 3.3552.

Since sin(146° + ∠B) cannot exceed 1, there is no solution for b that satisfies the triangle inequality. Therefore, no distinct triangle can be drawn with the given measurements.

How do you writer this function in standard form??

Answers

Question 1) Function defining the table:

From the table the x-intercepts are -2 and 1. This means the factors are:

(x+2) and (x-1)

Let

[tex]h(x) = a(x + 2)(x - 1)[/tex]

The point (-1,-1) satisfy this function since it is from the same table.

[tex] - 1 = a( - 1 + 2)( - 1 - 1) \\ - 1 = - 2a \\ a = \frac{1}{2} [/tex]

Therefore the function is

[tex]h(x) = \frac{1}{2} (x + 2)(x - 1)[/tex]

We expand to get:

[tex]h(x) = \frac{1}{2} ( {x}^{2} + x - 2)[/tex]

The standard form is:

[tex]h(x) = \frac{ {x}^{2} }{2} + \frac{x}{2} - 1[/tex]

Question 3) Parabola opening up

The x-intercepts are x=3 and x=7

The factors are (x-3), (x-7)

The factored from is

[tex]y = a(x - 3)(x - 7)[/tex]

The curve passes through (5,-4)

[tex] - 4= a( 5- 3)( 5 - 7) \\ - 4= - 4a \\ a = 1[/tex]

The equation is:

[tex]y = (x - 3)(x + 7)[/tex]

Expand:

[tex]y = {x}^{2} + 7x - 3x - 21[/tex]

[tex]y = {x}^{2} + 4x - 21[/tex]

This is the standard form:

Question 3) Parabola opening down:

The x-intercepts are x=-5 and x=1

The factors are (x+5), (x-1)

The factored form is

[tex]y = - (x + 5)(x - 1)[/tex]

We expand to get:

[tex]y = - ( {x}^{2} - x + 5x - 5)[/tex]

[tex]y = - {x}^{2} - 4x + 5[/tex]

This is the standard form.

If Henry were to add 5 gallons of water to a tank that is already 3434 full of water, the tank would be 7878 full. How many gallons of water would the tank hold if it were full

Answers

Answer:

The tank would hold 40 gallons of water when full.

Step-by-step explanation:

The tank is already 3/4 full of water

If Henry added 5 gallons, it will be 7/8 full.

Therefore the fraction added by Henry =7/8-3/4=1/8

It means that 1/8 of the total=5 gallons of water

Let the total capacity of the tank=x

[tex]\frac{1}{8}Xx=5 gallons\\ x=8X5=40 gallons[/tex]

The tank would hold 40 gallons of water when full.

You return a DVD movie that was 5 days overdue including a previous unpaid balance of $2.50, your new balance is $7.75. How much is the daily fine for an overdue DVD?

Answers

Answer:

$ 1.05

Step-by-step explanation:

To solve the problem it is necessary to pose some equations, which are the following:

Debt DVD = New Balance - Old Balance

With this we will calculate the net value that only has to do with the debt of the DVD:

Debt DVD: 7.75 - 2.50 = 5.25

Now, the other equation is the value per day that generates a delay.

Debt DVD / # days

Replacing

5.25 / 5 = 1.05

Then the daily fine for a overdueDVD is $ 1.05
