Answer:

(a)∴A=$6753.71.

(b)∴A=$1480.24

(c) ∴P=$7424.70

(d)∴P=$49759.62

(e)∴P=$5040.99

(f) ∴P=$2496.11

Step-by-step explanation:

We use the following formula

[tex]A=P(1+\frac rn)^{nt}[/tex]

A=amount in dollar

P=principal

r=rate of interest

(a)

P=$2,500, r=5%=0.05,t =20 years , n= 4

[tex]A=\$2500(1+\frac{0.05}{4})^{(20\times 4)[/tex]

   =$6753.71

∴A=$6753.71.

(b)

P=$1,000, r=8% =0.08,t =5 years , n= 2

[tex]A=\$1000(1+\frac{0.08}{2})^{(5\times 2)[/tex]

   =$1480.24

∴A=$1480.24

(c)

A=$10,000, r=6% =0.06,t =5 years , n= 4

[tex]10000=P(1+\frac{0.06}{4})^{(5\times 4)}[/tex]

[tex]\Rightarrow P=\frac{10000}{(1+0.015)^{20}}[/tex]

[tex]\Rightarrow P=7424.70[/tex]

∴P=$7424.70

(d)

A=$100,000, r=6% =0.06,t =10 years , n= 12

[tex]100000=P(1+\frac{0.07}{12})^{(10\times 12)}[/tex]

[tex]\Rightarrow P=\frac{100000}{(1+\frac{0.07}{12})^{120}}[/tex]

[tex]\Rightarrow P=49759.62[/tex]

∴P=$49759.62

(e)

A=$100,000, r=10% =0.10,t =30 years , n= 12

[tex]100000=P(1+\frac{0.10}{12})^{(30\times 12)}[/tex]

[tex]\Rightarrow P=\frac{100000}{(1+\frac{0.10}{12})^{360}}[/tex]

[tex]\Rightarrow P=5040.99[/tex]

∴P=$5040.99

(f)

A=$100,000, r=7% =0.07,t =20 years , n= 4

[tex]100000=P(1+\frac{0.07}{4})^{(20\times 4)}[/tex]

[tex]\Rightarrow P=\frac{100000}{(1+\frac{0.07}{4})^{80}}[/tex]

[tex]\Rightarrow P=2496.11[/tex]

∴P=$2496.11

To find the balance A, we use the formula A = P(1 + r/n)^(nt). To find the principal P, we rearrange the formula to P = A / ((1 + r/n)^(nt)).

(a) To find the balance A, we can use the formula A = P(1 + r/n)^(nt). Plugging in the given values, we have:

A = $2,500(1 + 0.05/4)^(4*20) = $2,500(1.0125)^80 ≈ $9,005.29

(b) Using the same formula, we can calculate:

A = $1,000(1 + 0.08/2)^(2*5) = $1,000(1.04)^10 ≈ $1,483.11

(c) To find the principal P, we rearrange the formula: P = A / ((1 + r/n)^(nt)). Plugging in the given values, we get:

P = $10,000 / ((1 + 0.06/4)^(4*5)) ≈ $7,772.22

(d) Using the rearranged formula, we can calculate:

P = $50,000 / ((1 + 0.07/12)^(12*10)) ≈ $23,022.34

(e) Since the compounding is monthly, we need to calculate the value of r/n first: r/n = 0.10/12 ≈ 0.0083. Plugging in the values, we have:

P = $100,000 / ((1 + 0.0083)^(12*30)) ≈ $3,791.61

(f) Similarly, we calculate:

P = $100,000 / ((1 + 0.07/4)^(4*20)) ≈ $24,084.48

[tex]p_{5} (t) = x^{5} - 5\cdot x^{4} + 3\cdot x^{3} +9\cdot x^{2}[/tex], for [tex]r_{1} = 0[/tex]

Step-by-step explanation:

The general form of quintic-order polynomial is:

[tex]p_{5}(t) = a\cdot x^{5} + b\cdot x^{4} + c\cdot x^{3} + d\cdot x^{2} + e \cdot x + f[/tex]

According to the statement of the problem, the polynomial has the following roots:

[tex]p_{5} (t) = (x - r_{1})\cdot (x-3)^{2}\cdot x^{2} \cdot (x+1)[/tex]

Then, some algebraic handling is done to expand the polynomial:

[tex]p_{5} (t) = (x - r_{1}) \cdot (x^{3}-6\cdot x^{2}+9\cdot x) \cdot (x+1)\\p_{5} (t) = (x - r_{1}) \cdot (x^{4}-5\cdot x^{3} + 3 \cdot x^{2} + 9 \cdot x)[/tex]

[tex]p_{5} (t) = x^{5} - (5+r_{1})\cdot x^{4} + (3 + 5\cdot r_{1})\cdot x^{3} +(9-3\cdot r_{1})\cdot x^{2} - 9 \cdot r_{1}\cdot x[/tex]

If [tex]r_{1} = 0[/tex], then:

[tex]p_{5} (t) = x^{5} - 5\cdot x^{4} + 3\cdot x^{3} +9\cdot x^{2}[/tex]

The polynomial P(x) given has a degree of 5, leading coefficient of 1, roots at 3, 0 (both with multiplicity 2), and -1 (with multiplicity 1). It can be written as P(x) = (x - 3)^2 * x^2 * (x + 1), according to the Fundamental Theorem of Algebra.

A polynomial P(x) of degree 5 with a leading coefficient of 1 and roots at x = 3, x = 0 with multiplicity 2, and x = -1 with multiplicity 1 can be expressed as:

P ( x ) = (x - 3)^2 * x^2 * (x + 1)

This polynomial function is derived based on the fundamental theorem of algebra that states each polynomial equation of degree 'n' has 'n' roots or zeros, considering multiplicity. Here, the factors (x-3)^2, x^2 and (x+1) correspond to the roots 3, 0 and -1 with their respective multiplicities. Multiplicity refers to the number of times a number occurs as a root in the polynomial function.

Answer: the expression for the combined total number of miles she biked in the two days is

117 - 5x miles

Step-by-step explanation:

Let x be the number of hours she biked yesterday.

In the two days, she biked for a combined total time of 9 hours. This means that the number of hours that she biked today is (9 - x) hours.

Distance = speed × time

Yesterday, Carmen went on a bike ride. Her average speed was 8 miles per hour. This means that the distance that she covered yesterday is 8x miles

Today, she went on another ride, this time averaging 13 miles per hour. This means that the distance that she covered today is 13(9 -x) miles.

An expression for the combined total number of miles she biked in the two days is

8x + 13(9 - x)

= 8x + 117 - 13x

= 117 - 5x

Step-by-step explanation:

Answer: a) [tex]\frac{x^{2} }{2352.25 }[/tex] + [tex]\frac{y^{2} }{529}[/tex] = 1

b) The distance of two foci is 85.4 feet

c) Area = 3502.67 square feet

Step-by-step explanation: a) An ellipse has the equation in the form of:

[tex]\frac{x^{2} }{a^{2} }[/tex]+[tex]\frac{y^{2} }{b^{2} }[/tex] = 1, where a is the horizontal axis and b is the vertical axis.

For the Statuary Hall, a = [tex]\frac{97}{2}[/tex] = 48.5 and b = [tex]\frac{46}{2}[/tex] = 23, so the equation will be

[tex]\frac{x^{2} }{2352.25 }[/tex] + [tex]\frac{y^{2} }{529}[/tex] = 1.

b) To determine the distance of the foci, we have to calculate 2c, where c is the distance between one focus and the center of the ellipse. To find c, as a, b and c create a triangle with a as hypotenuse:

[tex]a^{2}[/tex] = [tex]b^{2} + c^{2}[/tex]

[tex]c^{2} = a^{2} - b^{2}[/tex]

c = [tex]\sqrt{48.5^{2} - 23^{2} }[/tex]

c = 42.7

The distance is 2c, so 2·42.7 = 85.4 feet.

The two foci are 85.4 feet apart.

c)The area of an ellipse is given by:

A = a.b.π

A = 48.5 · 23 · 3.14

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

c represents the y intercept

m represents the slope of the line.

The equation of the given line is

y = - 2x + 3

Comparing with the slope intercept form, slope = - 2

If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.

Therefore, the slope of the line passing through (4, - 3) is 1/2

To determine the y intercept, we would substitute m = 1/2, x = 4 and y = -3 into y = mx + c. It becomes

- 3 = 1/2 × 4 + c

- 3 = 2 + c

c = - 3 - 2

c = - 5

The equation becomes

y = x/2 - 5

Multiplying through by 2, it becomes

2y = x - 5

x - 2y - 5 = 0

Therefore

A = 1

B = - 2

C = - 5

The equation y = 0.75x + 2 represents the cost of going to the festival and picking x pounds of apples.

The equation provided,  y = 0.75x + 2 , follows the form  y = mx + b, where \y represents the total cost,  x represents the number of pounds of apples picked, 0.75x  represents the cost of apples at $0.75 per pound, and  2 represents the admission fee.

This equation allows you to calculate the total cost y based on the number of pounds of apples picked x , including both the admission fee and the cost per pound of apples.

Answer: she bought 5 greeting cards at $2.50 each.

Step-by-step explanation:

Let x represent the number of greeting cards that she bought at $2.50 each.

Let y represent the number of greeting cards that she bought at $4 each.

She buys some greeting cards that cost $2.50 each and some greeting cards that cost $4 each. She buys 12 cards. This means that

x + y = 12

The total amount that she spent in buying the greeting cards is $40.50. It means that

2.5x + 4y = 40.5- - - - - - - - - - 1

Substituting x = 12 - y into equation 1, it becomes

2.5(12 - y) + 4y = 40.5

30 - 2.5y + 4y = 40.5

- 2.5y + 4y = 40.5 - 30

1.5y = 10.5

y = 10.5/1.5

y = 7

x = 12 - y = 12 - 7

x = 5

Maya bought 5 greeting cards that cost $2.50 each.

Step 1

Let's denote the number of greeting cards that cost $2.50 as x, and the number of greeting cards that cost $4 as y . We know two things from the problem statement:

1. Maya buys a total of 12 cards: x + y = 12 .

2. The total cost of the cards is $40.50: 2.50x + 4y = 40.50.

Now, we'll solve these equations simultaneously to find x .

From equation (1):

x + y = 12

y = 12 - x

Step 2

Substitute y = 12 - x into equation (2):

[tex]\[ 2.50x + 4(12 - x) = 40.50 \][/tex]

Expand and simplify:

[tex]\[ 2.50x + 48 - 4x = 40.50 \][/tex]

[tex]\[ -1.50x + 48 = 40.50 \][/tex]

Subtract 48 from both sides:

[tex]\[ -1.50x = 40.50 - 48 \][/tex]

[tex]\[ -1.50x = -7.50 \][/tex]

Step 3

Divide both sides by -1.50 to solve for x :

[tex]\[ x = \frac{-7.50}{-1.50} \][/tex]

[tex]\[ x = 5 \][/tex]

So, Maya bought x = 5 greeting cards that cost $2.50 each.

Verification:

Now, substitute x = 5 back into the equation y = 12 - x  to find y :

y = 12 - 5

y = 7

Check the total cost:

[tex]\[ 2.50 \cdot 5 + 4 \cdot 7 = 12.50 + 28 = 40.50 \][/tex]

Everything checks out correctly. Therefore, Maya bought 5 greeting cards that cost $2.50 each.

Answer:

Step-by-step explanation:

Hello!

The variable of interest is

X: number of 18-20-year-olds that consume alcoholic beverages in a sample of 50.

The proportion of underage people that drinks are known to be p= 0.697

This variable is discrete. This experiment has two possible outcomes success or failure, we will call "success" each time we encounter an underage individual that consumes alcohol and "failure" will be counting an underage that does not consume alcohol. The number of repetitions of the trial is fixed n= 50. All randomly selected underage individuals are independent and the probability of success is constant trough the whole experiment p=0.697.

Then we can say that this variable has a binomial distribution and we will use that distribution to do the calculations.

a. Under a binomial distribution, the expected value is calculated as:

E(X)= n*p= 50*0.697= 34.85.

The variance of a binomial distribution is:

V(X)= n*p*(1-p)= 50*0.697*0.303= 10.55955

And the standard deviation is the square root of the variance:

√V(X)= 3.2495 ≅ 3.25

b. To know how rare the value 45, you have to see how distant it is concerning the expected value. For this you have to subtract the expected value and divide it by the standard deviation:

[X-E(X)]/√V(X)

(45-34.85)/3.25= 3.12

The value X=45 is 3.12 standard deviations above the mean, which means that it would be rare to find 45 people or more than consumed alcohol.

c. P(X≥45) = 1 - P(X<45)= 1 - P(X≤44)= 1 - 0.9994= 0.0006

I hope it helps!

The required values are:

a) Expect to have consumed alcoholic beverages[tex]=np=34.85[/tex]

and, Standard Deviation [tex]\sigma =3.25[/tex]

b) yes, 45 is more than two standard deviations above the expected value(mean)

C) Probability[tex]=0.0015[/tex]

The subject of this question is Mathematics, specifically set theory, and it is geared towards High School grade level.

Let's break this down step by step:

To find the number of adults who watched both programs, we subtract the number who watched the New Movie but not the Big Game from the total number who watch the New Movie:

285 (watched New Movie) - 183 (watched the New Movie but not the Big Game) = 102 adults watched both programs (a)

To find the number of adults who watched at least one program, we subtract the number who watched neither from the total number of adults:

644 (total number of adults) - 228 (watched neither) = 416 adults watched at least one program (b)

To find the number of adults who watched the Big Game, we add the number who watched both to those who watched only the Big Game. The later is calculated by subtracting those who watched both and those who watched neither from the total number of adults:

644 (total number of adults) - 102 (watched both) - 228 (watched neither) = 314 watched the Big Game (c)

And finally, to calculate the number of adults who watched the Big Game but not the New Movie, we subtract the ones who watched both from total Big Game watchers:

314 (watched Big Game) - 102 (watched both) = 212 watched the Big Game but not the New Movie (d)

Answer:she had $63.75 at first.

Step-by-step explanation:

Let x represent the amount of money that she had at first.

kathy spent 3 fifths of her money on a necklace. This means that the amount of money that she spent on the necklace is

3/5 × x = 3x/5

The amount of money remaining would be

x - 3x/5 = 2x/5

She used 2 thirds of the remainder on a bracelet. This means that the amount of money that she spent on the bracelet is 2/3 × 2x/5 = 4x/15

If the bracelet costs $17.00, then

4x/15 = 17

4x = 15 × 17

4x = 255

x = 225/4

x = 63.75

Final answer:

Kathy had $63.75 at first. We determined this by dividing the cost of the bracelet by 2 to find 1/3 of the remainder, then multiplying by 3 to find the full remainder, and finally calculating the total by multiplying by 5.

Explanation:

To solve the problem of how much money Kathy had at first, we need to work backwards from the cost of the bracelet. Kathy spent 2 thirds of the remainder of her money on a bracelet that costs $17.00. If 2/3 of the remainder equals $17, then 1/3 of the remainder would be $17 / 2 = $8.50. This means the full remainder (3/3) would be 3 times $8.50, which is $25.50. This remainder represents the 2/5 of her original amount, as she spent 3/5 on the necklace.

To find out the full amount of money Kathy had, we need to figure out what number 2/5 of it is $25.50. So, if 2/5 equals $25.50, then 1/5 equals $25.50 / 2 = $12.75. Finally, to find the total amount Kathy had at first, we multiply $12.75 by 5 (since her total money is 5/5), giving us $63.75 as the total amount of money Kathy had originally.

Answer:

2 chocolate balls with 1 coconut for chocolate

3 chocolate balls with 4 of coconut for coconut

Step-by-step explanation:

In this case, what should be done to know when it will taste more chocolate or coconut, is to get the percentage of each one with respect to the total there is. Analyzing each case would be:

2 chocolate balls with 1 coconut, total 3 balls.

% chocolate = (2/3) * 100% = 66.6%; % coconut = (1/3) * 100% = 33.3%

3 chocolate balls with 2 coconut, total 5 balls

% chocolate = (3/5) * 100% = 60%; % coconut = (2/5) * 100% = 40%

4 chocolate balls with 3 coconut, total 7 balls

% chocolate = (4/7) * 100% = 57.14%; % coconut = (3/7) * 100% = 42.86%

3 chocolate balls with 4 coconut, total 7 balls

% chocolate = (3/7) * 100% = 42.86%; % coco = (4/7) * 100% = 57.14%

6 chocolate balls with 4 coconut, in total 10 balls

% chocolate = (6/10) * 100% = 60%; % coconut = (4/10) * 100% = 40%

3 chocolate balls with 3 coconut, in total 6 balls

% chocolate = (3/6) * 100% = 50%; % coconut = (3/6) * 100% = 50%

When it tastes more like chocolate it is in the case of 2 chocolate balls with 1 coconut, which contains 66.6% chocolate, therefore it is when it tastes more like chocolate.

When it tastes more like coconut it is in the case of 3 chocolate balls with 4 of coconut, a total of 7 balls, which contains 57.14% chocolate, therefore it is when it tastes more like coconut.

Answer:

F(x)=-1/5x-7

Step-by-step explanation:

You have to switch signs and flip the orgininal slope to get a perpendicular one.

5 will become - 5

Then it will become -1/5 because 5 on its own is equivalent to -5/1

Answer: the slope is - 1/5

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form which is expressed as

y = mx + c

Where

m represents the slope

c represents the y intercept

Comparing with the given equation,

Slope, m = 5

If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line. Therefore, the slope of the line perpendicular to

F(x)=5x-7 is - 1/5

Answer: Xn = n(n+1)/2

Step-by-step explanation:

Firstly, you work with asingle dot for each and let n= 1,2,3,4....

Now if you double the dots, it will form a rectangle and it is easier to work with many dots i.e just multiple n by n+1

Dots in rectangle= n(n+1)

But remember the number of dots were doubled therefore,

Dots in triangle = n(n+1)/2.

Option B:

The relationship between angle j and angle k is j° + k° = 180°.

Solution:

Given JKLM is a parallelogram.

angle J and angle K are consecutive angles.

To find the relationship between angle j and angle k:

In parallelogram, the sum of the consecutive angles is 180°.

⇒ m∠J + m∠K = 180°

⇒ j° + k° = 180°

Hence the relationship between angle j and angle k is j° + k° = 180°.

Option B is the correct answer.

In parallelogram JKLM, angle J and angle K are congruent or have the same measure.

In parallelogram JKLM, angle J and angle K are congruent. This means that they have the same measure.

A parallelogram is a quadrilateral with opposite sides that are parallel. Since the opposite sides of a parallelogram are parallel, the opposite angles are also congruent.

Therefore, angle J and angle K in parallelogram JKLM have the same measure.

Answer:

7.54 sq. inches

Step-by-step explanation:

The cake with the cut portion has been shown in the figure below.

For calculating the area of cut part we first need to calculate the area of whole cake.

Diameter of the cake is given in the question as 12 inches.

So the area of the cake = [tex]\pi \frac{Diameter^2}{4}[/tex] = [tex]3.14 \times \frac{12\times12}{4} = 113.04[/tex] [tex]inches^2[/tex]

Since when the central angle is 360°, the area is 113.04 square inches

So when the central angle is 24°, the area of the section will be

[tex]\frac{113.04\times 24}{360} =7.54[/tex]

Thus area of the slice cut by Nestor is 7.54 sq. inches.

Fraction = [tex]\frac{7.54}{113.04} = 0.07[/tex]

Answer:

(a) P(X = 0) = 1/3

(b) P(X = 1) = 2/9

(c) P(X = −2) = 1/9

(d) P(X = 3) = 0

(a) P(Y = 0) = 0

(b) P(Y = 1) = 1/3

(c) P(Y = 2) = 1/3

Step-by-step explanation:

Given:

- Two 3-sided fair die.

- Random Variable X_1 denotes the number you get for rolling 1st die.

- Random Variable X_2 denotes the number you get for rolling 2nd die.

- Random Variable X = X_2 - X_1.

Solution:

- First we will develop a probability distribution of X such that it is defined by the difference of second and first roll of die.

- Possible outcomes of X : { - 2 , -1 , 0 ,1 , 2 }

- The corresponding probabilities for each outcome are:

                  ( X = -2 ):  { X_2 = 1 , X_1 = 3 }

                  P ( X = -2 ):  P ( X_2 = 1 ) * P ( X_1 = 3 )

                                 :  ( 1 / 3 ) * ( 1 / 3 )

                                 : ( 1 / 9 )

                  ( X = -1 ):  { X_2 = 1 , X_1 = 2 } + { X_2 = 2 , X_1 = 3 }

                 P ( X = -1 ):  P ( X_2 = 1 ) * P ( X_1 = 3 ) + P ( X_2 = 2 ) * P ( X_1 = 3)

                                 :  ( 1 / 3 ) * ( 1 / 3 ) + ( 1 / 3 ) * ( 1 / 3 )

                                 : ( 2 / 9 )

       ( X = 0 ):  { X_2 = 1 , X_1 = 1 } + { X_2 = 2 , X_1 = 2 } +  { X_2 = 3 , X_1 = 3 }

       P ( X = -1 ):P ( X_2 = 1 )*P ( X_1 = 1 )+P( X_2 = 2 )*P ( X_1 = 2)+P( X_2 = 3 )*P ( X_1 = 3)

                                 :  ( 1 / 3 ) * ( 1 / 3 ) + ( 1 / 3 ) * ( 1 / 3 ) + ( 1 / 3 ) * ( 1 / 3 )

                                 : ( 3 / 9 ) = ( 1 / 3 )

                    ( X = 1 ):  { X_2 = 2 , X_1 = 1 } + { X_2 = 3 , X_1 = 2 }

                 P ( X = 1 ):  P ( X_2 = 2 ) * P ( X_1 = 1 ) + P ( X_2 = 3 ) * P ( X_1 = 2)

                                 :  ( 1 / 3 ) * ( 1 / 3 ) + ( 1 / 3 ) * ( 1 / 3 )

                                 : ( 2 / 9 )

                    ( X = 2 ):  { X_2 = 1 , X_1 = 3 }

                  P ( X = 2 ):  P ( X_2 = 3 ) * P ( X_1 = 1 )

                                    :  ( 1 / 3 ) * ( 1 / 3 )

                                    : ( 1 / 9 )                  

- The distribution Y = X_2,

                          P(Y=0) = 0

                          P(Y=1) =  1/3

                          P(Y=2) = 1/ 3

- The probability for each number of 3 sided die is same = 1 / 3.

Answer:

5 cents.

Step-by-step explanation:

We have been George has $2.00 to spend at a store. He buys 3 cans of soda. Each can of soda costs 65 cents.

First of all George should calculate the total cost of 3 cans of soda by multiplying 3 by $0.65.

[tex]\text{Cost of 3 cans of soda}=\$0.65\times 3[/tex]

[tex]\text{Cost of 3 cans of soda}=\$1.95[/tex]

Now, George should subtract $1.95 from $2.00 to find the amount of change as:

[tex]\text{Amount of change that George will receive}=\$2.00-\$1.95[/tex]

[tex]\text{Amount of change that George will receive}=\$0.05[/tex]

Therefore, George will receive 5 cents in change.

Answer:

0.05 cents

Step-by-step explanation:

Given that George has $2.00 to spend at a store. He buys 3 cans of soda. Each can of soda costs 65 cents.

George has to use both multiplication and subtraction to find out the change

Spending at a store ...  2.00$

Cost of each can ... 0.65$

cost of 3 cans      ...  3*0.65 = 1.95$

Change he receives   ... 2-1.95 =0.05 cents
