Follow the steps above, and find c, the total of the payments related to financing, and the monthly payment. A customer buys an automobile from you, the salesman. The price of the car, which includes taxes and license, amounts to $5,955.00. The customer wants to finance the car over 48 months after making a $500 down payment. You inform him that the true annual interest rate is 18%.

Answers

Answer 1

the monthly payment is approximately $163.06 and the total payments related to financing are approximately $7834.88.

To find the monthly payment and the total payments related to financing, we need to follow these steps:

1. Calculate the total amount financed.

2. Use the total amount financed to calculate the monthly payment using the formula for monthly payments on a fixed-rate loan.

3. Multiply the monthly payment by the number of months to find the total payments related to financing.

Given:

- Price of the car = $5955.00

- Down payment = $500.00

- Finance period = 48 months

- Annual interest rate [tex]\(= 18\%\)[/tex]

Step 1: Calculate the total amount financed.

The total amount financed is the difference between the price of the car and the down payment.

[tex]\[ \text{Total amount financed} = \text{Price of the car} - \text{Down payment} \][/tex]

[tex]\[ \text{Total amount financed} = \$5955.00 - \$500.00 \][/tex]

[tex]\[ \text{Total amount financed} = \$5455.00 \][/tex]

Step 2: Calculate the monthly payment.

To calculate the monthly payment, we use the formula for the monthly payment on a fixed-rate loan:

[tex]\[ M = \frac{P \times r \times (1 + r)^n}{(1 + r)^n - 1} \][/tex]

Where:

- M is the monthly payment

- P is the principal amount (total amount financed)

- r is the monthly interest rate (annual interest rate divided by 12)

- n is the number of payments (finance period in months)

First, we need to convert the annual interest rate to a monthly interest rate:

[tex]\[ r = \frac{18\%}{12} = 0.18 \times \frac{1}{12} = 0.015 \][/tex]

Now, we plug in the values:

[tex]\[ M = \frac{5455 \times 0.015 \times (1 + 0.015)^{48}}{(1 + 0.015)^{48} - 1} \][/tex]

[tex]\[ M ≈ \frac{5455 \times 0.015 \times (1.015)^{48}}{(1.015)^{48} - 1} \][/tex]

Using a calculator, we find that the monthly payment M is approximately $163.06.

Step 3: Calculate the total payments related to financing.

[tex]\[ \text{Total payments} = \text{Monthly payment} \times \text{Number of months} \][/tex]

[tex]\[ \text{Total payments} = \$163.06 \times 48 \][/tex]

[tex]\[ \text{Total payments} ≈ \$7834.88 \][/tex]

So, the monthly payment is approximately $163.06 and the total payments related to financing are approximately $7834.88.

Answers

Answer:

The factored form is  [tex](8x-32)=8(x-4)[/tex]

Step-by-step explanation:

Given : A youth club receives a discount on each pizza purchased for a party. The original price of each pizza is x dollars. The club leader purchases 8 pizzas for a total of (8x-32) dollars.

To find : Factor the expression ?

Solution :

The original price of each pizza is x dollars.

The club leader purchases 8 pizzas for a total of [tex](8x-32)[/tex] dollars.

To factor the expression we have to take common term out.

So, [tex]8x=8\times x[/tex]

[tex]32=8\times 4[/tex]

8 is common take out,

[tex](8x-32)=8(x-4)[/tex]

Factors are 8 and (x-4).

Therefore, the factored form is  [tex](8x-32)=8(x-4)[/tex]

Final answer:

To factor the expression (8x - 32), we take out the common factor of 8, resulting in the factored form of 8(x - 4), indicating a $4 discount per pizza.

Explanation:

The question is asking to factor the expression, which represents the total cost for purchasing 8 pizzas after receiving a discount from the original price x dollars per pizza. The expression given is (8x - 32) dollars.

To factor this expression, we look for a common factor in both terms which is 8.

Factoring out the 8, we get 8(x - 4). This means the club receives a discount of $4 per pizza since (8x - 32) factors into 8 times (x - 4).

Which of the following statements would be correct to use when proving that limx→4(3x−4)=8?

e. Given 0<∣∣x−4∣∣<3ϵ, then ∣∣(3x−4)−8∣∣<ϵ.
f. Given 0<∣∣x−4∣∣<3ϵ, then ∣∣(3x−4)−8∣∣<ϵ3.

Answers

Answer:

Option c

Step-by-step explanation:

given that limit x tending to 4 of the function (3x-4) is 8

This implies for all values of x such that for epsilon >0 arbitrary small ,

[tex]||x-4||<\epsilon[/tex], we get

|f(x)-8|<3epsilon

this is equivalent to the option c.

Proof:

Consider

[tex]||x-4||<\epsilon\\3||x-4||<3\epsilon\\||3x-12||<3\epsilon\\||3x-4|-8| <3\epsilon[/tex]

Hence it follows that option C is right.

Final answer:

The correct statement to use when proving that limx→4(3x−4)=8 is option b: Given 0 < | x - 4 | < epsilon/3, then | (3x - 4) - 8 | < epsilon. This uses the formal definition of limit and abides the epsilon-delta parameters definition to provide the correct proof.

Explanation:

To verify the given limit, we need to utilize the formal definition of a limit. This formal definition gives us a systematic method to prove a limit based on epsilon-delta parameters. The purpose is to show that as x gets closer and closer to 4 (with| x - 4 | being smaller than an arbitrary positive delta), the expression (3x-4) increasingly approaches 8 (with |(3x - 4) - 8| getting within an epsilon range).

The correct choice is: b. Given 0 < | x - 4 | < epsilon/3, then | (3x - 4) - 8 | < epsilon. In this case, 'epsilon/3' in | x - 4 | < 'epsilon/3' is the delta in the epsilon-delta definition of limit. Essentially, it captures the notion that for every epsilon > 0, there exists a delta > 0 such that 0 < | x - 4 | < delta implies | (3x - 4) - 8 | < epsilon, thereby proving the limit.

If Alex and Brandon work together they will clean the school in 15 hours. Working alone, Brandon can finish the same job in 20 hours. How long will it take Alex to do the job by himself? PLEASE HELP ME PRETTY PLEASE

Answers

Answer:

It takes 60 hours for Alex to complete the job alone.

Step-by-step explanation:

Given:

Number of hours Brandon alone can finish job =20 hours

Let the number of hours required by Alex alone to complete the job be 'x' hrs.

We need to find the number of hours required by Alex alone to complete the job.

Solution:

Now we can say that;

Rate at which Alex can complete the job alone = [tex]\frac1x[/tex] job/hour

Rate at which Brandon can complete the job alone = [tex]\frac{1}{20}[/tex] job /hour

Also Given:

Number of hours required for both to complete the job = 15

So rate of both complete the job  = [tex]\frac{1}{15}[/tex] job/hour

Now we can say that;

rate of both complete the job is equal to sum of Rate at which Alex can complete the job alone and Rate at which Brandon can complete the job alone.

framing in equation form we get;

[tex]\frac1x+\frac{1}{20}=\frac{1}{15}[/tex]

Now taking LCM for making the denominators same we get;

[tex]\frac{20}{20x}+\frac{x}{20x}=\frac{1}{15}[/tex]

Now denominators are common so we will solve the numerators.

[tex]\frac{20+x}{20x}=\frac{1}{15}[/tex]

Now Using cross multiplication we get;

[tex]15(20+x)=20x[/tex]

Applying Distributive property we get;

[tex]15\times20+15\times x =20x\\\\300+15x=20x[/tex]

Combining like terms we get;

[tex]300=20x-15x\\\\300=5x[/tex]

Now Dividing both side by 5 we get;

[tex]\frac{300}{5}=\frac{5x}{5}\\\\x=60\ hrs[/tex]

Hence It takes 60 hours for Alex to complete the job alone.

Final answer:

To find how long it will take Alex to complete the job by himself, we first establish the individual work rates of Alex and Brandon. We know the combined work rate (1/15 jobs per hour) and Brandon's work rate (1/20 jobs per hour). Alex's work rate is thus 1/15 - 1/20 = 1/60 jobs per hour, which means it will take him 60 hours to do the job alone.

Explanation:

This question requires knowledge of work rate calculations in Mathematics. The scenario involves two workers, Alex and Brandon, who can complete a cleaning task together in 15 hours. It's also given that Brandon can do the job alone in 20 hours, and we need to calculate how long it would take for Alex to complete the job by himself.

First, let's define their rates of work. If Brandon can complete the job in 20 hours, his work rate is 1 job per 20 hours, or 1/20 jobs per hour. Similarly, if Alex and Brandon together can complete the job in 15 hours, their combined work rate is 1 job per 15 hours, or 1/15 jobs per hour.

To find Alex's work rate, we subtract Brandon's work rate from the combined work rate. Thus, Alex's work rate is 1/15 - 1/20 = 1/60 jobs per hour. This means it would take Alex 60 hours to complete the job on his own.

Complete the proof of the Pythagorean theorem.

Answers

Final answer:

The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse's length equals the sum of the squares of the other two sides' lengths. This can be proven via the areas of squares with sides corresponding to the triangle's sides, demonstrating that a²+b²=c².

Explanation:

The Pythagorean theorem is a fundamental principle in geometry, named after the Greek mathematician Pythagoras. It states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be written as: a²+b²=c².

To prove this, we can begin with a right-angled triangle with sides a, b, and hypotenuse c. If we square the length of c (i.e., c²), this is equivalent to the area of a square with side length c. Similarly, a² and b² represent the areas of squares with side lengths a and b, respectively.

If we add together the areas of the two smaller squares (a²+b²), this equals the area of the larger square (c²). This proves the Pythagorean theorem. For instance, consider a right triangle with sides of lengths 3, 4, and 5. The squares would have areas 9 and 16, which add up to 25 - the area of the square on the hypotenuse.

The Pythagorean Theorem states that a² + b² = c². A step-by-step proof involves constructing a square with the right-angled triangle and equating the areas. This logical deduction confirms the theorem's correctness.

The Pythagorean Theorem is one of the fundamental results in Geometry, which states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c². Here is a step-by-step proof:

Construct a right-angled triangle with legs a and b and hypotenuse c.Construct a square with side a + b. Within this square, place four identical right-angled triangles, each having sides a, b, and c.The four triangles will leave a smaller square in the middle with side c.The area of the larger square is (a + b)², which can be expanded as a² + 2ab + b².The area of the larger square is also the sum of the areas of the four triangles and the smaller square in the center, which is 4 (1/2ab) + c² simplifying to 2ab + c².Setting the two expressions for the area of the larger square equal gives: a² + 2ab + b² = 2ab + c².By subtracting 2ab from both sides, we get the Pythagorean Theorem: a² + b² = c².

Thus, we have proven that the theorem holds true using logical deductions.

Answers

Answer:

7.41 m/s

Step-by-step explanation:

Force of a car inclined at an angle

F=mg Sin Θ where; m = 2956 kg , g = 9.8m/s² , Θ = 35⁰

F = 2956 x 9.8 x Sin 35 = 16615.82 N

Net force due to friction = 16615.82 - 3080 = 13535.82 N

To calculate acceleration; F= Ma

13535.82 = 2956 x a

a = 4.58 m/s²

From equation of motion

[tex]V^{2} = V_{o} ^{2} + 2aS[/tex]

V² =  0 + (2 x 4.58 x 6)

V = [tex]\sqrt{54.95}[/tex]

c=54.69

Final answer:

The monthly cost for pre-paid cell phone usage can be expressed as a function, C = 18.5 + 0.11x where x is the number of calling minutes. The monthly cost for making 329 minutes of calls would be $54.69.

Explanation:

The pre-paid cell phone company charges a fixed monthly access fee and an additional cost per minute of calling time. Here, the monthly access fee is $18.5 and the cost per minute is $0.11. We are asked to express the monthly cost C as a function of x, the number of minutes used.

Therefore, we can write the function as C = 18.5 + 0.11x where, C represents the monthly cost and x represents the number of minutes used.

Now, if you make 329 minutes of calls this month, you can use this function to calculate the total cost. Substituting x = 329 into the function gives: C = 18.5 + 0.11 * 329 = $54.69.

Therefore, the monthly cost for making 329 minutes of calls would be $54.69.

What is the range of g(x) = 3|x − 1| − 1? A. (-∞, 1] B. [-1, ∞) C. [1, ∞) D. (-∞, ∞)

Answers

Answer:

B. [-1, ∞).

Step-by-step explanation:

g(x) = 3|x − 1| − 1

When x = 1  g(x) = 3(0) - 1 = -1.

As all negative vales of x will give positive values of  |x - 1| then  g(x) = -1 is its minimum value. The graph will be shaped like a letter V with the vertex at (1,-1).

Therefore the range is  [-1, ∞).

The range of g(x)=3|x-1|-1 is [-1,∞) i.e. option B is correct.

What is range?

The set of all the outputs of a function is known as the range of the function .

According to the given question

we have,

A function, g(x) = 3|x-1| - 1

Lets, find the value of g(x) for the different values of "x"

when,

x=0 ⇒ g(0) = -1

x=1 ⇒ g(1) = -1

x=2 ⇒g(2) = 2

Similarly, we can check for the negative values of x.

Answer:

Yes to both.

Step-by-step explanation:

It is true that

[tex]\dfrac{x}{y}=1 \iff x=y[/tex]

In fact, if you know that x/y=1, just multiply both sides by y to get x=y. On the other hand, if you know that x=y (and they are not zero), you can divide both sides by y to get x/y=1.

Since the two expressions are equivalent, you can always use Phil's or Don's expression, at will.

A department store is holding a drawing to give away free shopping sprees. There are customers who have entered the drawing: live in the town of Gaston, live in Pike, and live in Wells. Two winners will be selected at random. What is the probability that both winners live in Wells?

Answers

Answer:

The probability of selecting two winners from Wells is, [tex]\frac{z(z-1)}{(x+y+z)(x+y+z-1)}[/tex]

Step-by-step explanation:

Let us assume that x people entered the drawing were from Gaston, y people entered the drawing were from Pike and z people entered the drawing were from Wells.

Total number of people who entered the drawing is, N = x + y + z.

It is provided that 2 winners are selected at random.

The event of selecting the first and second winner are not related, i.e. they are independent.

Then the first winner can be selected from Wells in z ways.

And the second winner can be selected, also from Wells in (z - 1) ways.

The probability of selecting both the winners from Wells is:

[tex]P(Both\ the\ winners\ were\ from\ Wells)=\frac{z}{x+y+x}\times \frac{z-1}{x+y+z-1} =\frac{z(z-1)}{(x+y+z)(x+y+z-1)}[/tex]

Thus, the probability of selecting two winners from Wells is, [tex]\frac{z(z-1)}{(x+y+z)(x+y+z-1)}[/tex].

An experimenter conducted a two-tailed hypothesis test on a set of data and obtained a p-value of 0.44. If the experimenter had conducted a one-tailed test on the same set of data, which of the following is true about the possible p-value(s) that the experimenter could have obtained? A) The only possible p-value is 0.44. B) The only possible p-value is 0.88. C) The possible p-values are 0.22 and 0.78. D) The possible p-values are 0.22 and 0.88.

Answers

Answer:

Correct option is (C).

The possible value of the p-value for a one-tailed test are 0.22 and 0.78.

Step-by-step explanation:

The p-value is the probability of acquiring a result as extreme as the observed result, assuming the null hypothesis statement is true.

The p value of a test is:

Left-tailed test: [tex]P(TS<ts)[/tex]

Right-tailed test: [tex]P(TS>ts) = 1- P(TS<ts)[/tex].

Here,

TS = Test statistic

ts = computed value of the test statistic.

The two-tailed p-value is: [tex]2P(TS<ts)[/tex] or [tex]2P(TS>ts)[/tex].

The p-value of the two tailed test is, 0.44.

Compute the p-value for one-tailed test a follows:

For a left-tailed test:

            [tex]2P(TS<ts)=0.44\\P(TS<ts)=\frac{0.44}{2}\\ =0.22[/tex]

For a right-tailed test:

            [tex]P(TS>ts) = 1- P(TS<ts)\\=1-0.22\\=0.78[/tex]

Thus, the possible value of the p-value for a one-tailed test are 0.22 and 0.78.

The correct option is (C).

Final answer:

Given a p-value of 0.44 from a two-tailed test, the equivalent one-tailed test would yield a p-value of 0.22. Out of the provided choices, option C is closest to the correct interpretation.

Explanation:

The question presented is about the computation of the p-value in a one-tailed test, given the p-value from a two-tailed test. A p-value essentially indicates the probability that you would obtain the observed data, or data more extreme if the null hypothesis is true. In this instance, the experimenter has a p-value of 0.44 from a two-tailed test.

When converting this to a one-tailed test, the p-value would effectively be halved. Therefore, if they conducted a one-tailed test on the same data, the p-value would be 0.22 (i.e., 0.44/2) in the direction specified by the alternative hypothesis. Thus, between the provided options, none are perfectly correct, but option C) 'The possible p-values are 0.22 and 0.78.' is closest to the correct interpretation, with the accurate p-value being 0.22 rather than 0.78.

Mr wells drew a plan for a rectangle dog run three of the vertices are (2 1/3, 7 1/2), (12, 7 1/2), and (12, 1) what are the coordinates of the fourth vertex

Answers

Answer:

Step-by-step explanation:

let 4th fourth vertex be D (x,y)

A(2 1/3,7 1/2),B(12, 7 1/2),C(12,1)

or A(7/3,15/2),B(12,15/2),C(12,1)

Mid-point of diagonal AC is  P((7/3+12)/2,(15/2+1))

Mid -point of diagonal BD is P((12+x)/2,(15/2+y)/2)

(Because mid -point of diagonal is same.)

(12+x)/2=(7/3+12)/2

12+x=7/3+12

x=7/3

(15/2+1)/2=(15/2+y)/2

15/2+1=15/2+y

y=1

so fourth vertex is (7/3,1)

Final answer:

To find the coordinates of the fourth vertex of the rectangle, we use the information provided about the positions of the third vertex and the Car X figure. The coordinates of the fourth vertex are (13 2/3, 7 1/2) and (12, 2).

Explanation:

To find the coordinates of the fourth vertex of the rectangle, we can use the fact given that the third vertex is one and two-thirds perpendicular hash marks to the right of the center top hash mark. Since the center top hash mark is at (12, 7 1/2), the third vertex is at (12 + 1 2/3, 7 1/2), which simplifies to (13 2/3, 7 1/2).

Now, we need to find the position of the fourth vertex. According to the given information, the fourth vertex is in the same position as the Car X figure, which means it is one perpendicular hash mark above the center right hash mark. Since the center right hash mark is at (12, 1), the fourth vertex is at (12, 1 + 1), which simplifies to (12, 2).

Therefore, the coordinates of the fourth vertex are (13 2/3, 7 1/2) and (12, 2).

To ensure that all people with high cholesterol have an equal chance of being selected for the study To increase the accuracy of the research results and prevent skewness in the data To produce treatment groups with similar characteristics To control confounding

Answers

Answer: To produce treatment groups with similar characteristics

Step-by-step explanation:

The purpose of this experiment is to determine that the treatments groups with similar characteristics are produced. Every groups is taking different amount of the supplement so this study ensures that by randomly assigning the supplements, we can check the cholesterol level in the blood. In this way, similar characteristics in groups are imparted so we can then make treatment groups of same characteristics.

Final answer:

The purpose of random assignment in experiments is to avoid bias, increase the research results' accuracy, help in producing treatment groups with similar characteristics, and control confounding variables. In this case, it ensures that all participants have an equal chance of receiving any level of omega-3 fatty acid or placebo.

Explanation:

The purpose of random assignment in this experiment is multifold. Firstly, it ensures all participants, regardless of their cholesterol levels, have an equal chance of being selected. This prevents bias in the sample selection. Secondly, it increases the accuracy of the research results by preventing skewness in the data. The random assignment ensures that every participant has an equal chance of receiving any level of the omega-3 fatty acid supplement or the placebo. This helps produce treatment groups with similar characteristics, which in turn allows for fair comparisons to be made. Finally, it aids in controlling confounding variables. These are factors other than the independent variable (in this case, omega-3 fatty acid supplements) that may affect the dependent variable (cholesterol level), and random assignment helps to equalize these among the groups.
