Answer:

E (X) = 1.8

Var (X) = 0.36

σ = 0.6

Step-by-step explanation:

Solution:-

- Denote the random variable X : is the number of red marbles that Suzan has in her hand after she selects three marbles.

- Total sample space (bag) have the following quantity of colored marbles:

                Bag : { 3 Red , 2 Green }

- Suzan selects three marbles from the bag. The Event (X) defines the number of red marbles out of 3.

- The total number of outcomes / selections for randomly selecting 3 balls from the bag:

               All outcomes = 5 C 3 = 10

- The probability distribution of the random variable X, we will use combinations to determine the required probabilities:

  X = 1 red marble:

        P ( X = 1 ) : Suzan chooses 1 Red marble from the available 3 red marble and 2 green marbles.

        P ( X = 1 ) = [ 3C1*2C2 ] / all outcomes = (3*1) / 10 = 0.3

X = 2 red marble:

        P ( X = 2 ) : Suzan chooses 2 Red marble from the available 3 red marble and 1 green marbles.

        P ( X = 2 ) = [ 3C2*2C1 ] / all outcomes = (3*2) / 10 = 0.6

X = 3 red marble:

        P ( X = 3 ) : Suzan chooses 3 Red marble from the available 3 red marble.

        P ( X = 3 ) = [ 3C3] / all outcomes = (1) / 10 = 0.1

- The probability distribution is as follows:

          X :         1                 2                3

       P (X):       0.3            0.6              0.1

- The expected value E(X) for the given random variable X is:

                E ( X ) = ∑Xi*P(Xi)

                           = 1*0.3 + 2*0.6 + 3*0.1

                           =1.8

- The variance Var(X) for the given random variable X is:

                Var ( X ) = ∑Xi^2*P(Xi) - [ E(X) ] ^2

                               = 1^2*0.3 + 2^2*0.6 + 3^2*0.1 - 1.8^2

                               = 0.36

- The standard deviation for the given random variable X is:

                σ = √Var(X)

                σ = √0.36

                σ = 0.6

The expected value, the variance, and the standard deviation of the given random variable X are 1.8, 0.36, and 0.6 respectively and this can be determined by using the given data.

Given :

X is the number of red marbles that Suzan has in her hand after she selects three marbles from a bag containing three red marbles and two green ones.

The total number of outcomes are:

[tex]\rm \; ^5C_3=10[/tex]

The probability of random variable X are as follows:

X = 1 red marble

P(X = 1) = [tex]\rm \; ^3C_1 \times ^2C_2[/tex] = 0.3

X = 2 red marbles

P(X = 2) = [tex]\rm \; ^3C_2 \times ^2C_1[/tex] = 0.6

X = 3 red marbles

P(X = 3) = [tex]\rm \; ^3C_3[/tex] = 0.1

So, the expected value is given by:

[tex]\rm E(X) = \sum X_i \times P(X_i)[/tex]

        [tex]= 1\times 0.3+2\times 0.6 + 3 \times 0.1[/tex]

        = 1.8

Now, the variance is given by:

[tex]\rm Var(X) = \sum X^2_i \times P(X_i)-(E(X))^2[/tex]

           [tex]=1^2\times 0.3+2^2\times 0.6+3^2 \times 0.1-1.8^2[/tex]

           = 0.36

Now, the standard deviation is given by:

[tex]\rm \sigma=\sqrt{Var(X)}[/tex]

[tex]\rm \sigma = \sqrt{0.36}[/tex]

[tex]\sigma = 0.6[/tex]

Answer:

a.  total cost including discount = 64.47

b. sales would be greater if tax was added before

Step--step explanation:

The total cost of the shirts including the discount is $64.57 and  total cost of the shirts including the 6.5% sales tax would be greater if the tax was applied after a 15% discount is taken, rather than before.

percentage, a relative value indicating hundredth parts of any quantity.

The cost of one shirt after a 15% discount is $9.99 - ($9.99 x 0.15) = $8.49.

The cost of two shirts costing $11.99 each after a 15% discount

2 x ($11.99 - ($11.99 x 0.15)) = $20.38.

The cost of two shirts costing $21.00 each after a 15% discount

2 x ($21.00 - ($21.00 x 0.15)) = $35.70.

Therefore, the total cost of the shirts including the discount

$8.49 + $20.38 + $35.70

= $64.57.

If the tax is applied before the discount, then the taxable amount would be the original price of the shirts, which is $9.99 + (2 x $11.99) + (2 x $21.00) = $84.97.

The tax on this amount at 6.5% would be $5.52.

After the 15% discount, the total cost of the shirts would be $64.57, which includes the $5.52 tax.

Therefore, the total cost of the shirts after the discount and tax

$59.05 + $5.52 = $64.57.

The total cost of the shirts including the 6.5% sales tax would be greater if the tax was applied after a 15% discount is taken, rather than before.

Hence,  the total cost of the shirts including the discount is $64.57 and  total cost of the shirts including the 6.5% sales tax would be greater if the tax was applied after a 15% discount is taken, rather than before.

Step-by-step explanation:

Answer:

A rate

Step-by-step explanation:

Its a ratio that compares unlike units.

Answer:

The area of the bedroom actually is 453.75 sq ft.

Step-by-step explanation:

Given that,

A blueprint shows the master bedroom to be 5 inches long and 3 inches wide.

The scale on blueprint is 2 inches : 11 feet.

It means 2 inches = 11 feet.

Then,

1 inches [tex]=\frac{11}{2}[/tex] feet = 5.5 feet.

So,

The length of the bedroom is 5 inches = (5×5.5) feet=27.5 feet

The wide of the bedroom is 3 inches = (3×5.5) feet= 16.5 feet

The area of the bedroom actually is = length × wide

                                                            =(27.5×16.5) square ft

                                                            =453.75 square ft

Final answer:

To find the area of the actual bedroom, you need to use the scale provided on the blueprint. By setting up ratios and solving for the actual length and width, you can find that the area of the actual bedroom is 453.75 square feet.

Explanation:

To find the area of the actual bedroom, we need to use the scale provided on the blueprint. The scale states that 2 inches on the blueprint represents 11 feet in reality. So, we can set up a ratio to find the actual length and width of the master bedroom:

Length ratio: 2 inches ⁠∩⁠ 11 feet = 5 inches ⁠∩⁠ x feet
Width ratio: 2 inches ⁠∩⁠ 11 feet = 3 inches ⁠∩⁠ y feet

By cross-multiplying and solving for x and y, we can find that x = 27.5 feet and y = 16.5 feet. Therefore, the actual length of the bedroom is 27.5 feet and the actual width is 16.5 feet. To find the area, we simply multiply the length and width: Area = 27.5 feet × 16.5 feet = 453.75 square feet.

Answer: True

Step-by-step explanation:

If you draw a vertical number line, the numbers in it will infinitely extend in both directions (up and down), having the zero 0 as the neutral number (the origin).

Then, the numbers that are above the origin are the positive integers and represent the distance of an object above zero, while the numbers below the origin are the negative integers and represent perfectly the distance of an object underground (below the origin).

The statement is true, negative numbers can be used to represent the distance of an object below a reference point, such as underground relative to the surface.

True or false? You can represent the distance of an object underground using negative numbers.

The statement is true. In mathematics, especially when dealing with physical situations like displacements and positions, using negative numbers to indicate direction is a common practice. We often choose a frame of reference and a positive direction at the beginning of a problem. In this context, for example, if we define the surface of the ground as our reference point and the direction away from the center of the Earth (upwards) as positive, then it would take sense to use negative numbers to represent the distance of an object that is located underground, indicating it is below the reference point.

Answer:The answer is 50

Step-by-step explanation:

The first step is to add up the numbers in order to get the outcome

5 red + 20 blue +25 green =5+20+25 =50

Step 2

Probability =no of events /no of outcome

We were asked to find the probability of red

Where red represent event

And the summation of red ,green and blue represents outcome .

So probability of red =5/50 = 1/10

Step 3

Recall in the question ,we were told that the card was selected 500 times ,so we multiply the probability of getting red by 500

1/10 *500 =50

Therefore the probability of drawing a red card from the special deck 500 times is 50 .

Answer:

B

Step-by-step explanation:

2/36=1/18=0,056 it's too easy

The probability that the sum adds to 2 or 12 is P = 0.056.

We have two number cubes, each one has 6 outcomes, so the total number of outcomes is:

C = 6*6 = 36 outcomes.

Now, we need to find the number of outcomes that add up to 2 or 12, these are:

Dice 1  dice 2    sum

  1           1            2

Answer:

The amount of payment that needs to be applied to the debt balance to bring the debt to limit ratio to 15% is $2,250

Step-by-step explanation:

Here we have the card limit as $3,000

The card debit to limit ratio should be kept below 15%

Therefore, card limit of $3,000 = 100%

The protect FICA score card debt to limit ratio required required is 15% that is;

Maximum appropriate card debt is 15% of Max allowable card debt

Maximum appropriate card debt  = 15% of $3,000 = $450.00

Current debt on card = $3,000

Payment to be applied to the balance to pay it down to 15% is given by

[tex]\$3,000 - \frac{15}{100} \times \$3000 = \$3,000 - \$450 = \$2550[/tex]

Therefore a $2,550 payment will be applied to the balance to pay it down to 15%.

Final answer:

To reduce your credit card debt to 15% of a $3,000 limit, you would need to make a payment of $2,550. This is calculated by determining 15% of the limit and subtracting it from the current balance to find the necessary payment amount.

Explanation:

Calculating Payment to Lower Credit Card Debt to Ratio

If your credit card has a limit of $3,000 and you wish to keep your credit card debt to limit ratio below 15%, first determine what 15% of your credit limit is. Calculate 15% of $3,000, which is $450. Since your current balance is the full limit of $3,000, subtract the target balance of $450 from $3,000. The result is the payment needed to reduce your debt to within the desired ratio.

$3,000 * 0.15 = $450 (15% of your credit limit)

$3,000 - $450 = $2,550

Therefore, a payment of $2,550 will bring your balance down to 15% of the credit limit. Managing your credit utilization is important not just for meeting the credit score components but also for maintaining good financial health.

Answer:

correct option is  C. $399,060

Step-by-step explanation:

given data

balloon mortgage = 7/23

initial payments = $915

time = 30 year

new payments = $895

solution

we know here that 7/23 is that loan has fixed rate =  first 7  years.

so that initial payments for 7 years is here

initial payment = 7 × 12 × 915

initial payment = $76860

and

payments for 30 years when refinance her balloon

payments for 30 year = 30 × 12 × 895

payments for 30 year = $322200

so total financed cost paid for her house is

total financed cost =  $76860 + $322200  

total financed cost = $399,060

so correct option is  C. $399,060

Final answer:

To determine the total financed cost of Margaret's house, one must sum the payments made during the initial balloon mortgage and the subsequent 30-year mortgage, totaling $399,060 (Option C).

Explanation:

The total financed cost that Margaret paid for her house can be calculated by adding the payments made during her initial 7-year balloon mortgage period to the payments for the 30-year mortgage she refinanced into.

For the balloon mortgage: 7 years = 84 months. Therefore, the total paid during this period is 84 months × $915/month = $76,860.

For the refinanced mortgage: 30 years = 360 months. Hence, the total paid after refinancing is 360 months × $895/month = $322,200.

Adding these two amounts gives us the total financed cost which is $76,860 + $322,200 = $399,060. The answer to the student’s question is C. $399,060.

Step-by-step explanation:

Symmetry is when you can flip the figure over a line and it will perfectly match the other side.

Then notice that we can draw two diagonals across the image, one from the upper left corner to the lower right corner and the other from the upper right corner to the lower left corner. That's another 2.

We try to find more, but try as we might, there are no others to be found.

Thus, there are 4 lines of symmetry.

Answer: Approximately 33 feet

Step-by-step explanation: Please refer to the attched diagram.

The 20ft ladder is placed on the wall at an agle of 85° with the ground.

If the person on the ladder were to lean back and fall to the ground (rotating the ladder away from the wall), then the distance he would have covered before he hits the ground is depicted by the arc as shown in the diagram. The ladder upon touching the ground would remain the same, which is 20 feet. So what the question requires is the length of the arc made during the fall, and the length of the ladder both on the wall an on the floor would be the radius (20 ft) while the angle subtended by the arc is 95° ( angles on a straight line equals 180, that is 85 + 95 = 180)

Therefore the length of an arc is given as;

Length of arc = (∅/360) x 2πr

Where ∅ = 95 and r = 95

Length of arc = (95/360) x 2 x 3.14 x 20

Length of arc = (19/72) x 125.6

Length of arc = 2386.4/72

Length of arc = 33.1444

Length of arc ≈ 33 feet (To the nearest foot)

The person on the ladder would have travelled approximately 33 feet before he/she hits the ground.

The person falls a distance of approximately 19.924 feet.

In this question, we must determine the vertical distance travelled by the person ([tex]y[/tex]), in feet. Let consider that the ladder is set between a horizontal ground and a vertical wall.

Then, the vertical distance is determined by the following trigonometric expression:

[tex]y = l\cdot \sin\theta[/tex] (1)

Where:

If we know that [tex]l = 20\,ft[/tex] and [tex]\theta = 85^{\circ}[/tex], then the vertical distance travalled by the person:

[tex]y = (20\,ft)\cdot \sin 85^{\circ}[/tex]

[tex]y \approx 19.924\,ft[/tex]

The person falls a distance of approximately 19.924 feet.
