The Smith Family is buying a house for $350,000 with a down payment of $70,000 for a 15-year loan, $66 per month insurance, property tax is $230 per month and HOA is $600 per year. Calculate their total monthly payment
Using monthly payment formula, the Smith Family's total monthly payment is approximately $2,360.99.
What is the Monthly Payment?To calculate the total monthly payment for the Smith Family, we need to consider the mortgage payment, insurance, property tax, and HOA fees.
1. Mortgage Payment:
The loan amount is the house price minus the down payment:
$350,000 - $70,000 = $280,000.
To calculate the monthly mortgage payment, we need to determine the interest rate and loan term. Since you mentioned it's a 15-year loan, we'll assume an interest rate of 4% (which can vary depending on market conditions and the borrower's credit).
We can use a mortgage calculator formula to calculate the monthly payment:
M = P [i(1 + i)ⁿ] / [(1 + i)ⁿ⁻¹]
Where:
M = Monthly mortgage payment
P = Loan amount
i = Monthly interest rate
n = Number of months
The monthly interest rate is the annual interest rate divided by 12, and the loan term is 15 years, which is 180 months.
i = 4% / 12 = 0.00333 (monthly interest rate)
n = 180 (loan term in months)
Plugging in the values into the formula:
M = $280,000 [0.00333(1 + 0.00333)¹⁸⁰] / [(1 + 0.00333)¹⁸⁰⁻¹]
Using a calculator, the monthly mortgage payment comes out to be approximately $2,014.99.
2. Insurance:
The monthly insurance payment is given as $66.
3. Property Tax:
The monthly property tax payment is given as $230.
4. HOA Fees:
The HOA fees are stated as $600 per year. To convert this to a monthly payment, we divide by 12 (months in a year): $600 / 12 = $50 per month.
Now, let's add up all these expenses:
Mortgage payment: $2,014.99
Insurance: $66
Property tax: $230
HOA fees: $50
Total monthly payment = Mortgage payment + Insurance + Property tax + HOA fees
Total monthly payment = $2,014.99 + $66 + $230 + $50
Total monthly payment = $2,360.99

Which of the following is not a proper sample space when all undergraduates at a university are considered? S = {freshmen, sophomores} S = {in-state, out-of-state} S = {age under 21, age 21 or over} S = {a major within business, no business major}
The sample space that is not proper when considering all undergraduates at a university is S = {age under 21, age 21 or over}. This is because age is not a defining factor for classifying undergraduates, and it is not mutually exclusive or collectively exhaustive.
It is possible for an undergraduate to fall into both categories, creating an overlap. On the other hand, S = {freshmen, sophomores} and S = {in-state, out-of-state} are proper sample spaces because they are mutually exclusive and collectively exhaustive. S = {a major within business, no business major} is also a proper sample space because it is mutually exclusive, and all undergraduates will fall into one of these categories. When defining a sample space, it is important to consider if the categories are exclusive and exhaustive, and if they apply to all members of the population being studied.

A line is perpendicular to y = -1/5x + 1 and intersects the point negative (-5,1) what is the equation of this perpendicular line?
Answer: y = 5x + 26
Step-by-step explanation:
To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.
We can use the point-slope form of a linear equation to find the equation of the line:
y - y1 = m(x - x1)
Substituting the values, we get:
y - 1 = 5(x - (-5))
Simplifying further:
y - 1 = 5(x + 5)
Expanding the brackets:
y - 1 = 5x + 25
Rearranging the equation to the slope-intercept form (y = mx + b):
y = 5x + 26
Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

In a game, a player earns 100 points for each question answered correctly and earns -30 points for each question answered incorrectly. A player answered 14 questions correctly and 6 questions incorrectly.
Part A) Write a numeric expression to represent the total number of points the player earned.
Part B) Determine the total number of points.
The general expression is 130 x - 600 and total points scored by the player is 1220
A) Let the number of correctly answered questions be x.
∴ Number of incorrectly answered questions will be 20 - x.
+ 100 points is awarded for each question answered correctly while -30 points is awarded for each question answered incorrectly.
Thus, the general equation becomes
= 100x - (20 - x)(-30)
= 100x +30x - 600
= 130x - 600
Thus the general expression becomes 130 x - 600
B) The player answers 14 questions correctly, thus x = 14
Substituting the value of x =14 in the general equation we get,
= 130(14) - 600
= 1820 - 600
= 1220.
Thus the total points scored by the player will be 1220

a) (f+g)(x)
to add the function , add like terms
\(\begin{gathered} f(x)+g(x)=(f+g)(x)=x^2+2x+3x^2-1 \\ (f+g)(x)=x^2+2x+3x^2-1 \\ (f+g)(x)=4x^2+2x-1 \end{gathered}\)so

How do you write an equation of a line through points (3,1) and (4,-4)?
Answer:
y = - 5x + 16
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (3, 1 ) and (x₂, y₂ ) = (4, - 4 )
m = \(\frac{-4-1}{4-3}\) = \(\frac{-5}{1}\) = - 5 , then
y = - 5x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (3, 1 )
1 = - 5(3) + c = - 15 + c ( add 15 to both sides )
16 = c
y = - 5x + 16 ← equation of line

(Calculator Active) Find the volume of the solid whose base is the region bounded by the parabola x^2 = 4y and the line y = 2, and each plane section perpendicular to the x-axis is an equilateral triangle.
o 1.131 o 7.838 o 0.980 o 5.226
The correct answer is: volume is approximately 5.226.
To find the volume of the solid, we need to integrate the area of the equilateral triangles along the x-axis, from the minimum to the maximum x value that corresponds to the region bounded by the parabola x^2 = 4y and the line y = 2.
First, we find the x values where the parabola and line intersect. For this, we substitute y = 2 into the parabola equation:
x^2 = 4(2) → x^2 = 8
The x values are -√8 and √8.
Next, we find the height of the equilateral triangle at a particular x value. To do this, we find the base length of the triangle using the distance between the parabola and line:
Base length = x^2/4 - 2
The height of an equilateral triangle can be expressed in terms of its base length:
Height = (base length * √3) / 2
Now, we substitute the base length and integrate the area of the triangles with respect to x:
Volume = ∫[(-√8, √8)] (x^2/4 - 2) * (√3) / 2 dx
Volume = (√3 / 8) ∫[(-√8, √8)] (x^4 - 16x^2) dx
After calculating the integral, we find:
Volume ≈ 5.226
So the correct answer is approximately 5.226.

what is the main difference in calculations for the independent samples t-test when the variances are equal and the variances are unequal?
The main difference in calculations for the independent samples t-test when the variances are equal and the variances are unequal is the method used to calculate the pooled variance, the t-value, and the degrees of freedom.
1. When variances are equal (also called pooled variance):
- Calculate the pooled variance using the formula:
\(Sp^2 = [(n1-1) × s1^2 + (n2-1) × s2^2] / (n1 + n2 - 2)\)
- Calculate the t-value using the formula:
\(t = (M1 - M2) / sqrt(Sp^2 × (1/n1 + 1/n2))\)
- Determine the degrees of freedom using the formula:
df = n1 + n2 - 2
2. When variances are unequal (also called Welch's t-test):
- Calculate the t-value using the formula:
\(t = (M1 - M2) / sqrt((s1^2 / n1) + (s2^2 / n2))\)
- Determine the degrees of freedom using the formula:
\(df = [(s1^2 / n1 + s2^2 / n2)^2] / [(s1^2 / n1)^2 / (n1 - 1) + (s2^2 / n2)^2 / (n2 - 1)]\)
