Consider a home mortgage of $ at a fixed APR of % for years.
a. Calculate the monthly payment.
b. Determine the total amount paid over the term of the loan.
c. Of the total amount paid, what percentage is paid toward the principal and what percentage is paid for interest.
a.) So the monthly payment is $550.27. b.) the total amount paid over the term of the loan is $99,048.60. c.) Approximately 50.43% of the total amount paid goes towards principal, and 49.57% goes towards interest.
What would be the monthly payment?The calculation for a fixed-rate mortgage can be used to get the monthly payment:
Monthly Payment is equal to P * r * [(1 + r)n - 1] / [(1 + r)n]
When P represents the loan's principle, r represents the monthly interest rate (calculated by dividing the annual interest rate by 12), and n represents the total number of monthly payments.
When we enter the values, we obtain:
Monthly Payment is equal to 50,000 * (0.11/12) * (1 + 0.11/12) * [((1 + 0.11/12))*180 - 1)]
= $550.27 (rounded to the nearest cent) (rounded to the nearest cent)
the amount due each month is $550.27.
What would the total amount paid over the term of the loan be?We can multiply the monthly payment by the number of payments to get the total amount paid over the course of the loan. There will be 180 payments total in this instance (15 years times 12 months per year).
Monthly Payment * Number of Payments = $550.27 * 180 to get the total amount paid.
= $99,048.60 (rounded to the nearest cent) (rounded to the nearest cent)
Hence, the total amount paid during the loan's period is $99,048.60.
What percentage is paid toward the principal and what percentage is paid for interest?An amortization schedule can be used to calculate the portion of the total payment that goes to principle and interest. According to this arrangement, the principal and interest portions of each monthly payment are separated.
We may create the loan's amortization plan using an online mortgage calculator as follows:
Month Payment Principal Interest Balance
1 $550.27 $265.85 $284.42 $49,734.15
2 $550.27 $265.85 $284.42 $49,734.15
... ... ... ... ...
179 $550.27 $529.26 $21.02 $840.96
180 $550.27 $532.69 $17.58 $0.00
This table shows that the total amount paid in interest is $49,048.60, whereas the total amount paid in principal during the course of the loan is $50,000 (the original loan amount).
We can use the following calculations to determine what portion of the entire payment is allocated to principle and interest:
Principal Paid / Total Paid * 100% = $50,000 / $99,048.60 * 100% is the percentage of principal.
= 50.43%
Interest Paid / Total Paid * 100% = $49,048.60 / $99,048.60 * 100% = 49.57% is the percentage of interest.
Hence, around 49.57% of the total payment is spent on interest, and 50.43% is spent on principal.

A student bought a 10-speed bike on sale for $92. She paid for the bike in $10 bills and toonies. If the number of $10 bills exceeds the number of toonies by 2, how many of each did she use? Toonie = 200 cents / 2.00 dollars
The student used 6 toonies (worth $12) and 8 $10 bills (worth $80) to pay for the bike.
what is distribution?
Distribution can refer to various things depending on the context, but in general, it means the act of dividing or sharing something among a group of people or things.
In mathematics and statistics, distribution refers to the pattern or spread of values of a variable in a population or a sample. It describes how the values of a variable are distributed or arranged, and can be represented by a probability distribution or a frequency distribution.
In business and economics, distribution refers to the process of getting products or services from the manufacturer or producer to the consumer or end user. It involves various activities such as transportation, warehousing, and retailing, and is an important part of the supply chain management.
In politics and social sciences, distribution can refer to the allocation of resources or benefits among individuals or groups in a society. It can involve issues such as income distribution, wealth distribution, and resource allocation, and is a key concern in social justice and welfare policies.
In general, distribution is a fundamental concept that involves the division or sharing of something, and can be applied in various fields and contexts.
Let's start by using algebra to solve the problem. Let x be the number of toonies and x + 2 be the number of $10 bills.
The total cost of the bike is $92, which is equivalent to 9200 cents. The number of toonies is x, which is worth 200 cents each, so the total value of the toonies is 200x cents. The number of $10 bills is x + 2, which is worth 1000 cents each, so the total value of the $10 bills is 1000(x + 2) cents. Therefore, we can write the equation:
200x + 1000(x + 2) = 9200
Simplifying and solving for x:
1200x + 2000 = 9200
1200x = 7200
x = 6
Therefore, the student used 6 toonies (worth $12) and 8 $10 bills (worth $80) to pay for the bike.

In a random sample of 50 frogs, 17 had elevated mercury content. Is there significant evidence (at the alpha = 0.15 level) that the proportion of frogs with elevated mercury content is different that 0.5?
There is significant evidence that the proportion of frogs with elevated mercury content is different than 0.5, The p-value is approximately 0.038.
What is significant evidence?
To test whether the proportion of frogs with elevated mercury content is significantly different from 0.5, we can use a one-sample proportion test. The null hypothesis is that the true proportion is 0.5, and the alternative hypothesis is that it is different from 0.5.
Let's calculate the test statistic and p-value using the following formula:
z = (p - P0) / √(P0*(1-P0)/n)
where p is the sample proportion (17/50 = 0.34), P0 is the null hypothesis value (0.5), and n is the sample size (50).
z = (0.34 - 0.5) / √(0.5*0.5/50) = -2.07
The calculated z-value is -2.07. We can find the p-value by looking up the area to the left of -2.07 in the standard normal distribution table or by using a statistical software package. The p-value is approximately 0.038.
Since the p-value (0.038) is less than the alpha level of 0.15, we can reject the null hypothesis and conclude that there is significant evidence that the proportion of frogs with elevated mercury content is different than 0.5.

A real estate broker decides to lease a car for 36 months. Suppose the anual interest rate is 7.8%, the negotiated price is $49,000, there is no trade-in, and the down payment is $4,000. Find the monthly lease payment (in dollars). Assume that the residual value is 49% of the MSRP of $51,500. (Round your answer to the nearest cent.)
Answer:
To find the monthly lease payment, we need to use the formula:
Monthly lease payment = (Net capitalized cost - Residual value) / Lease term in months
where:
Net capitalized cost = negotiated price - down payment
Residual value = percentage of MSRP x MSRP
Lease term in months = 36
First, we need to calculate the net capitalized cost:
Net capitalized cost = $49,000 - $4,000 = $45,000
Next, we need to calculate the residual value:
Residual value = 49% x $51,500 = $25,235
Now we can plug in the values and solve for the monthly lease payment:
Monthly lease payment = ($45,000 - $25,235) / 36 = $548.76
Therefore, the monthly lease payment is approximately $548.76.

A scientist collected 75 water samples from local streams. Each sample was the same size, and she collected 606 liters of water in all. What was the volume of each water sample?
8.08 liters.
To find the volume of each water sample, we need to divide the total volume of water collected by the number of samples collected.
Volume of each water sample = Total volume of water collected / Number of samples collected
We are given that the total volume of water collected is 606 liters, and the number of samples collected is 75.
Volume of each water sample = 606 / 75
Volume of each water sample = 8.08 liters
Therefore, the volume of each water sample is 8.08 liters.
A parabola opening up or down has vertex (0, -2) and passes through (6, 1). Write its
equation in vertex form.
Answer: y = (1/12)x^2 - 2
Step-by-step explanation:
The equation of a parabola in vertex form is given by:
y = a(x-h)^2 + k
where (h,k) is the vertex of the parabola and "a" is a coefficient that determines the shape of the parabola.
In this case, the vertex is given as (0, -2), so h = 0 and k = -2. Also, the parabola passes through the point (6, 1), which means that when x = 6, y = 1. We can use this information to solve for "a".
Substituting the values of h, k, x, and y in the equation, we get:
1 = a(6-0)^2 - 2
Simplifying this equation, we get:
1 + 2 = 36a
3 = 36a
a = 3/36
a = 1/12
Now that we know the value of "a", we can substitute it in the vertex form equation to get the final equation of the parabola:
y = (1/12)(x-0)^2 - 2
Simplifying this equation, we get:
y = (1/12)x^2 - 2
Therefore, the equation of the parabola in vertex form is y = (1/12)x^2 - 2.

A graph of the coordinates of the vertices of the image after a dilation by the given scale factor and center of dilation is shown in the image below.
What is dilation?In Geometry, dilation simply refers to a type of transformation which typically changes the size of a geometric object, but not its shape.
Next, we would apply a dilation to the coordinates of the pre-image by using a scale factor of 0.5 centered at the origin as follows:
Ordered pair J (-8, 0) → J' (-8 × 0.5, 0 × 0.5) = J' (-4, 0).
Ordered pair K (-4, 4) → K' (-4 × 0.5, 4 × 0.5) = K' (-2, 2).
Ordered pair L (-2, 0) → L' (-2 × 0.5, 0 × 0.5) = L' (-1, 0).
Next, we would have to dilate the coordinates of the preimage by using a scale factor of 1/3 centered at the point B (3, 3) by using this mathematical expression:
(x, y) → (k(x - a) + a, k(y - b) + b)
For coordinate A, B, and C, we have;
Coordinate A = (9, 9) → (1/3(9 - 3) + 3, 1/3(9 - 3) + 3) = (5, 5).
Coordinate B = (3, 3) → (1/3(3 - 3) + 3, 1/3(3 - 3) + 3) = (3, 3).
Coordinate C = (6, 0) → (1/3(6 - 3) + 3, 1/3(0 - 3) + 3) = (4, 2).
For coordinate D, E, and F, we have;
Coordinate D = (2, -2) → (1.5(2 - 4) + 3, 1.5(-2 + 2) + 3) = (0, 3).
Coordinate E = (4, -2) → (1.5(4 - 4) + 3, 1.5(-2 + 2) + 3) = (3, 3).
Coordinate F = (1, -4) → (1.5(1 - 4) + 3, 1.5(-4 + 2) + 3) = (-1.5, 0).

USA Today reported that the annual birth rate is 16 per 1000 people. you live in a community with 1000 people for 1 year. a) what is the exponential distribution? B) what is the probability of 10 birthsC)what is the probability that there more than 10 births D)what is te probability that there less than 10 births
The answers are as:
a) The exponential distribution is a probability distribution
b) P(X = 10) = 0.006
c) P(X > 10) ≈ 0.16
d) P(X < 10) ≈ 0.015
What is probability?
Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.
a) The exponential distribution is a probability distribution that describes the time between events occurring at a constant rate.
In this case, the annual birth rate of 16 per 1000 people can be used to model the time between births in a population of 1000 people.
b) To find the probability of 10 births in a population of 1000 people in 1 year using the exponential distribution, we can use the following formula:
[tex]P(X = x) = \lambda\ ^{(-\lambda x)}[/tex]
where λ is the rate parameter, which is equal to the annual birth rate of 16 per 1000 people divided by 365 (the number of days in a year) to give a daily birth rate of λ = 0.044. x is the number of births we are interested in, which is 10.
Therefore, we have:
P(X = 10) = [tex]0.044e^{(-0.044*10)}[/tex]
≈ 0.006
So the probability of exactly 10 births in a population of 1000 people in 1 year is approximately 0.6%.
c) To find the probability that there are more than 10 births, we need to sum the probabilities of 11 or more births:
P(X > 10) = Σ P(X = x) for x > 10
[tex]= \Sigma 0.044e^{(-0.044x)}[/tex] for x > 10
[tex]= 1 - \Sigma 0.044e^{(-0.044x)}[/tex]for x ≤ 10
P(X > 10) ≈ 0.16
So the probability of more than 10 births in a population of 1000 people in 1 year is approximately 16%.
d) To find the probability of less than 10 births in one year, we can use the CDF again:
[tex]F(x) = 1 - e^{(-\lambda x)}[/tex]
In this case, we want to find the probability of less than 10 births in one year, so x = 1 year and λ = 0.016 births per person per year:
[tex]F(10) = 1 - e^{(-0.016)}[/tex]
P(10) ≈ 0.0158
So less than 10 births in one year are approximately 1.5%.
Hence, The answers are as:
a) The exponential distribution is a probability distribution
b) P(X = 10) = 0.006
c) P(X > 10) ≈ 0.16
d) P(X < 10) ≈ 0.015

The calculation for future value of the an annuity can be used to resolve this issue:
FV = PMT x ((1 + r/n)nt - 1) / (r/n), where FV is just the future value of a annuity, PMT is indeed the payment amount (in this case, $500), r is indeed the interest rate (the value of which in this case is 12% or 0.12), n refers to the number of occasions a year the interest is greatly exacerbated (which in this case is four for quarterly cumulative), and t is the duration of the annuity .

b = 5000/2 = 2500
We can repeat this process for each time period and find the average value of b:
b = (2500 + 3125 + 3906.25 + 4882.81 + 6103.51 + 7629.38) / 6 = 4275.5
Now that we have the value of b, we can find the equation that models the relation:
y = 2000(4275.5)^x
Rounding to one decimal place:
y = 2000(4.3)^x
B. Using the equation, we can find the population after 12 and 24 hours:
y = 2000(4.3)^12 ≈ 8,898,335.7
y = 2000(4.3)^24 ≈ 7.42 x 10^13

5. Open Response Consider triangles ABC and
JKL as shown. (Lesson 3)
(See photo)
Answer:
Yes, these two triangles are similar. Triangle similarity can be proved by the measurement of the angles. Angle A= Angle J. Angle B= Angle K and Angle C= Angle L. Triangle ABC ≈(similar to) Triangle JKL.
Explanation:
Triangle JKL is dilated with a scale factor of 2. (all side lengths were doubled; multiplied by 2) which is an enlargement any scale factor greater then 1 is an enlargement which means the triangle size is being increased. Any scale factor less than one is a shrinkage. The 2 triangles have the same angle but not the same side lengths.
What is a dilation:
A dilation is a geometric transformation that changes the size of a shape. The only thing the changes in a dilation is the size. It can either get bigger or smaller (angle measurements DO NOT change)
Conclusion:
triangle similarity can be proved by AA similarity postulate.
i hope this helps :)
happy geometry studying!!
The police lieutenant in charge of the traffic division reviews the number of traffic citations issued by each of the police officers in his division. He finds that the mean number of citations written by each officer is 23.2 citations per day, with a standard deviation of 3.1. Assume that the distribution of the number of tickets issued is approximately bell-shaped. The coefficient of variation for the number of citations is
Answer:
[tex] \sf \: 13.36\%[/tex]
Step-by-step explanation:
The coefficient of variation (CV) is a measure of relative variability, which expresses the standard deviation as a percentage of the mean. It can be calculated as follows:
[tex] \sf \: CV = \frac{standard \: deviation}{mean} \times 100%[/tex]
In this case, the mean number of citations is 23.2, and the standard deviation is 3.1. Thus, the coefficient of variation is:
[tex] \sf \: CV = \frac{3.1}{23.2} \times 100% [/tex]
[tex] \sf = 13.36\%[/tex]
Therefore, the coefficient of variation for the number of citations is approximately 13.36%.
Find the measurements of the missing angles.
the measurements of the missing angles are-
c = 96°
a= 84°
b= 84°
e= 42°
d= 96°
f=96°
What does an angle mean?Both the largest and the tiniest walls of a skew are determined by an intersection of the lines that connect that make up its ends. A junction could possibly bring two routes together. Another result of two objects interacting is an angle. They most closely resemble dihedral shapes. Two line beams can be arranged in a variety of ways between their extremities to form a two-dimensional curve.
Here,
c = 96 °(A pair of vertically opposite angles are always equal to each other)
a + c = 180°(a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees)
so, a= 180°-96°
a= 84°
therefore, b = 84°(A pair of vertically opposite angles are always equal to each other)
as shown in figure, 2e = 84°
that is, e = 84°/2
e = 42°
2e+f = 180°(a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees)
f=180°-2e (placing the value of e)
f = 180° -84°
so, f=96°
therefore d = 96°(A pair of vertically opposite angles are always equal to each other)
therefore, the measurements of the missing angles are-
c = 96°
a= 84°
b= 84°
e= 42°
d= 96°
f=96°

A car was valued at $44,000 in the year 1992. The value depreciated to $15,000 by the year 2006.
A) What was the annual rate of change between 1992 and 2006?
r=---------------Round the rate of decrease to 4 decimal places.
B) What is the correct answer to part A written in percentage form?
r=---------------%
C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2009 ?
value = $ -----------------Round to the nearest 50 dollars.
In the exponential decay, A) r = -0.0839 , B) r = -8.39% , C) Value=$11,800.
What is exponential decay?
The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.
To find the annual rate of change between 1992 and 2006, we can use the formula:
r = [tex](V_2/V_1)^{1/n}-1[/tex]
where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.
=>r = -0.0839
Therefore, the rate of change between 1992 and 2006 is -0.0839.
To express the rate of change in percentage form, we can multiply the result from part A by 100:
=>r = -0.0839 x 100
=> r = -8.39%
Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.
To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.
From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:
where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.
=>V = 11792.51
Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

The third side of the right angled triangle is 45.
What is right angled triangle?
A right angled triangle, also known as a right triangle, is a type of triangle that has one angle that measures exactly 90 degrees, called the right angle. This angle is formed where the two shorter sides of the triangle meet.
To solve this problem, we can use the concept of special right triangles, specifically the 3-4-5 right triangle. In a 3-4-5 right triangle, the sides are in the ratio of 3:4:5.
Let's label the length of the triangle as [tex]$L$[/tex], the height as [tex]$H$[/tex], and the hypotenuse as [tex]X[/tex].
The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs is equal to the square of the hypotenuse. Therefore, we can set up the following equation:
[tex]$$ L^2 + H^2 = X^2 $$[/tex]
Substitute the given values.
We are given that [tex]$L = 27$[/tex] and [tex]$H = 36$[/tex], so we can substitute these values into the equation:
[tex]$$ 27^2 + 36^2 = X^2 $$[/tex]
Simplify the equation.
Evaluating the squares on the left side, we get:
[tex]$$ 729 + 1296 = X^2 $$[/tex]
Simplifying the right side, we get:
[tex]$$ 2025 = X^2 $$[/tex]
Solve for X.
Taking the square root of both sides, we get:
[tex]$$ X = \sqrt{2025} $$[/tex]
[tex]$$ X = 45 $$[/tex]
Therefore, the third side of the triangle is 45.

1,280 square feet
The area οf the actual bridge deck in square feet is 1,280 square feet.
What is Area?Area refers tο the measurement οf the size οf a twο-dimensiοnal surface, usually measured in square units such as square inches, square feet, οr square meters. It represents the amοunt οf space that is inside the bοundary οf a flat οbject οr shape.
The scale οf the drawing is 40:1, which means that the dimensiοns οf the scaled bridge deck are 40 times smaller than the actual bridge deck. Tο find the area οf the actual bridge deck in square feet, we need tο cοnvert the dimensiοns οf the scaled bridge deck frοm inches tο feet and then multiply by the square οf the scale factοr (40² = 1600).
The dimensiοns οf the scaled bridge deck in feet are:
24 inches = 2 feet
4 and 4/5 inches = 0.4 feet
Sο, the area οf the scaled bridge deck in square feet is:
2 feet x 0.4 feet = 0.8 square feet
Tο find the area οf the actual bridge deck in square feet, we need tο multiply the area οf the scaled bridge deck by the square οf the scale factοr:
Area οf actual bridge deck = 0.8 square feet x (40²) = 1280 square feet

Answer:
Step-by-step explanation:
The scale factor indicates the actual bridge is 40 times larger than the drawing.
Increase the scale dimensions by the factor of 40.
24 times 40 = 960"
4.8 times 40 = 192" (I changed 4 4/5 to 4.8)
Area = length times width
960 times 192 = 184320 sq inches actual bridge deck in square inches
Divide 183320 by 144 (sq inches in a square foot) = 1280 sq feet

The product between functions f(x) and g(x) gives:
(f·g)(x) = x⁵ - 2x³ + 2x² - 8x + 4
What is the product between the two functions?Here we have the functions:
f(x) = x³ - 4x + 2
g(x) = x² + 2
The product:
(f·g)(x) is just the product between the two functions, this gives:
f(x)·g(x)
Replacing these functions we will get.
(x³ - 4x + 2)*( x² + 2)
Expanding that product, we will get:
x³*x² + 2x³ - 4x*x² - 8x + 2x² + 4
x⁵ - 2x³ + 2x² - 8x + 4
That is the product.
