Answer:
$ 140,104.96
Step-by-step explanation:
The amount the bank will the individual is the present value of the total mortgage payment.
monthly mortgage payment=28%*$36,000/12=$840
the payment is meant for 30 years but 360 months i.e 12*30
the amount of loan is the present value of $840 monthly for 360 months with 0.5% interest rate per month
=pv(rate,nper,-pmt,fv)
rate is 0.5%
nper is 360 months
pmt is $840 per month
fv is the total payments which is unknown
=pv(0.5%,360,-840,0)=$140,104.96
The loan amount is closest to $ 140,104.96

Eastbound travels at 95 miles per hour the westbound train travels at 105 miles per hour .how long will it take for the two trains to be 480 miles apart
Answer:
48
Step-by-step explanation:
This is a linear equation, it goes as follows:
[tex]105(x) - 95(x) = 480[/tex]
x stands for hours.
Solving for x yields 10.
Keep in mind that 105 and 95 are miles per hour where 480 is miles. So multiplying [tex](\frac{miles}{hours}) (hours)[/tex] gives off hours which is what we are looking for.
Hope this helps.

The circumference of a hula hoop is 86 cm what is the radius of the hula hoop?
Formula for circumference that involves the radius ⇒ C = 2πr
Since we are given that the circumference is 86 cm, substitute it in.
86 = 2πr
Now, π is equal to approximately 3.14 so we can
plug 3.14 in for π and we have 86 cm = 2(3.14)r.
Now solve the equation.
2(3.14) is 6.28 and we have 86 cm = 6.28r.
Now divide both sides by 6.28 and we have 13.6942 = r.
So the radius of the hula hoop is 13.6942 cm.

\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned} y=2x+1 x−y=−3 Is (2,5)(2,5)left parenthesis, 2, comma, 5, right parenthesis a solution of the system?
Answer:
Yes
Step-by-step explanation:
Given the system of equations
[tex]\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned}[/tex]
We want to determine if (2,5) is a solution of the system.
We can do this by substitution of the given point into the equations and see if it holds.
Given (x,y)=(2,5), x=2, y=5
In the first equation
y=2x+1
5=2(2)+1
5=5
Therefore, the point (2,5) satisfies the first equation.
In the second equation
[tex]x-y=2-5=-3[/tex]
Since our result (-3) is equal to the Right Hand Side, the point also satisfies the second equation.
Therefore, (2,5) is a solution of the system.

Point A is at (2,-8) and the point C is at (-4,7). Find the coordinates of point B on AC such that the ratio of AB to BC is 2:1.
Answer:
The coordinates of point B are (-2, 2)
Step-by-step explanation:
We have two points: A and C.
The coordinates for A are (2, -8) and the coordinates for C are (-4, 7).
We have to find the coordinates of the point B, that satisfies the condition that the distance AB is 2 times the distance BC.
We also know that B is a point of the line AC.
We can calculate the line AC as a linear function y=mx+b.
The slope m is:
[tex]m=\dfrac{y_c-y_a}{x_c-x_a}=\dfrac{7-(-8)}{-4-2}=\dfrac{15}{-6}=-2.5[/tex]
Then, the y-intercept b can be calculated using the coordinates of one of the points, in this case point A:
[tex]y=-2.5x+b\\\\b=y_a+2.5x_a=-8+2.5*2=-8+5=-3[/tex]
Then, we know that B is a point of the linear function y=-2.5x-3, within the range x ∈ (-4; 2).
To have a ratio AB to BC of 2 to 1, we can divide the length of the line AC in 3 parts, and the point B will be located in the end of the segment nearer to point C.
In the picture attached, you can see the division of the segment AC in three parts and the location of point B=(x, y).
Applying the Thales theorem, we can divide the segment in the y-axis in three and calculate y, and the same for the x-axis.
Then, the coordinate y for the point B is:
[tex]y=y_c-(y_c-y_a)/3\\\\y=7-[7-(-8)]/3=7-15/3=7-5=2\\\\\\x=x_c-(x_c-x_a)/3\\\\x=-4-(-4-2)/3=-4-(-6)/3=-4+2=-2[/tex]
Then, the point B has coordinates (-2, 2).
We can verify the distances as:
[tex]AB=\sqrt{(2-(-2))^2+((-8)-2)^2}=\sqrt{16+100}=\sqrt{116}\\\\\\BC=\sqrt{((-2)-(-4))^2+(2-7)^2}=\sqrt{4+25}=\sqrt{29}\\\\\\\dfrac{AB}{BC}=\dfrac{\sqrt{116}}{\sqrt{29}}=\sqrt{\dfrac{116}{29}}=\sqrt{4}=2[/tex]

Step-by-step explanation:
A sample of 50 impossible whoppersandwiches have a mean fat content of 37.6g and standard deviation of 4.9g . A sample of 58 regular whopper sandwiches have a mean fat content of 39.3g and standard deviation of 2.7g. Use a 0.05 significance level to test the claim that the mean fat content for the impossible whopper is less than the mean fat content for the regular whopper.
(Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal.)
USE A 0.05 SIGNIFICANCE LEVEL TO TEST THE CLAIM:
H0: μ1____ μ2For Q17(circle one: equal to, less than, greater than, not equal to )
H1 : μ1____ μ2For Q18(circle one: equal to, less than, greater than, not equal to )
Test Statistic t=__________ Q19(ROUND TO 2 DECIMAL PLACES)
P-value: p =_____________ Q20(ROUND TO 4 DECIMAL PLACES)
Decision/Conclusion: _________________________________Q21(CIRCLE ONE BELOW) Reject H0, There is sufficient evidence to warrant the rejection of the claim.
OR
Fail to Reject H0, There is not sufficient evidence to warrant the rejection of the claim.
Construct an appropriate confidence interval ( ______________ Q22, _______________ Q23) (ROUND TO 3 DECIMAL PLACES)
Answer:
Step-by-step explanation:
H0: μ1____ μ2For Q17(circle one: equal to, less than or equal to, greater than or equal to, not equal to )
H1 : μ1____ μ2For Q18(circle one: equal to, less than, greater than, not equal to )
Formula for calculating the the test:
t = [ (x₁ - x₂) - d ] / sqrt[(s₁²/n₁) + (s₂²/n₂)]
where x₁ = 37.6, x₂ = 39.3, d = 0 assuming equality = 37.6 - 39.3 = -1.7
s₁² = 4.92 = 24.01, s₂² = 2.72 = 7.29, n₁ = 50, n₂ = 58.
thus, t = [ (-1.7) - (0)] / √(24.01/50) + (7.29/58)
t = (-1.7) / (0.4802 + 0.1257)
t = -1.7 / 0.6059
t = -2.8057. = -2.81
P value:
Lets find the degree of freedom:
DF = (s₁²/n₁ + s₂²/n₂)² / { [ (s₁² / n₁)² / (n₁ - 1) ] + [ (s₂² / n₂)² / (n₂ - 1) ] }
DF = (24.01/50 + 7.29/58)² / {[(24.01 / 50)² / 50-1)] + (7.29/58)² / 58-1)]}
DF = (0.4802 + 0.1257)² /{[ (0.4802)²/49] + (0.1257)²/57)]}
DF = (0.6059)²/ (0.00471 + 0.00028)
DF = 0.3671 / 0.00499 = 75.37
Thus, P value = 0.9968 using a t distribution calculator.
Decision/Conclusion: Since the P value 0.9968 is greater than α (.05), Fail to Reject H0, There is not sufficient evidence to warrant the rejection of the claim.
The following 96% confidence interval based on a sample of 32 students was formed to estimate the population mean time that students will require to complete a particular examination: 62.4 ± 12.6 minutes. Which one of the following interpretations is correct for this confidence interval?A) We are 96% confident that the population mean time required for all students who take this test is somewhere between 49.8 and 75.0 minutesB) We are 96% confident that the sample mean time (62.4 minutes) equals the true mean timeC) We are 96% confident that the population mean time required by students who take this test is 62.4 minutesD) We are 96% confident that the sample mean time (62.4 minutes) is correctE) We are 4% confident that an individual student taking this test will require less than 49.8 minutes or more than 75.0 minutes
Answer:
A) We are 96% confident that the population mean time required for all students who take this test is somewhere between 49.8 and 75.0 minutes
Step-by-step explanation:
x% confidence interval is between a ± b.
a is the sample mean.
b is the margin of error.
Interpretation: We are x% sure that the population mean is between a-b and a+b.
In this question:
96% confidence interval for the mean time that students will require to complete a particular examination. Between 62.4 - 12.6 = 49.8 minutes and 62.4 + 12.6 = 75 minutes.
The correct interpretation is that we are 96% sure that the population mean is in this interval.
So the correct answer is:
A) We are 96% confident that the population mean time required for all students who take this test is somewhere between 49.8 and 75.0 minutes
Answer:
The confidence interval for the true mean is given by the following formula:
[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex] (1)
The confidence interval for this case i given by:
[tex] 62.4 -12.6 \leq \mu \leq 62.4+12.6[/tex]
[tex] 49.8 \leq \mu \leq 75.0[/tex]
For this case we can conclude that the true mean for the time that students will require to complete a particular examination is between 49.8 and 75.0 minutes. And the best option for this case by:
A) We are 96% confident that the population mean time required for all students who take this test is somewhere between 49.8 and 75.0 minutes

What is the value of g(1⁄2) when g(x) = 2x2? What is the input? What is the output?
Answer:
[tex]g(\frac{1}{2}) = 0.5[/tex]
The input is [tex]x = \frac{1}{2}[/tex] and the output is [tex]g(x) = g(\frac{1}{2}) = 0.5[/tex]
Step-by-step explanation:
Suppose we have a function g(x) = a. The input is the value of x and the output is the value of g.
In this question:
[tex]g(x) = 2x^{2}[/tex]
We want g(1/2) = g(0.5). So
[tex]g(0.5) = 2*(0.5)^{2} = 2*0.25 = 0.5[/tex]
[tex]g(\frac{1}{2}) = 0.5[/tex]
The input is [tex]x = \frac{1}{2}[/tex] and the output is [tex]g(x) = g(\frac{1}{2}) = 0.5[/tex]
Determine a region of the xy-plane for which the given differential equation would have a unique solution whose graph passes through a point (x0, y0) in the region. (x2 + y2)y' = y2
1. A unique solution exists in the region y ≥ x.
2. A unique solution exists in the entire xy-plane.
3. A unique solution exists in the region y ≤ x.
4. A unique solution exists in the region consisting of all points in the xy-plane except the origin.
5. A unique solution exists in the region x2 + y2 < 1.
Answer:
4. A unique solution exists in the region consisting of all points in the xy-plane except the origin.
Step-by-step explanation:
Given:
[tex] (x^2 + y^2)y' = y^2[/tex]
Solving the differential equation, we have:
[tex] \frac{dy}{dx} = \frac{y^2}{x^2 + y^2}[/tex]
Thus, except at (0,0), for all real values of x and y, the function[tex] \frac{y^2}{x^2 + y^2}[/tex] is defined.
The (0,0) values of x&y causes the denominator to be 0, so the function is not defined at this (0,0) condition.
Therefore,
[tex] \frac{d}{dy} \frac{y^2}{x^2 + y^2} = \frac{x^2 + y^2 (2y) - y^2 (2y)}{(x^2 + y^2)^2} [/tex]
[tex] = \frac{2x^2y + 2y^3 - 2y^3}{(x^2 + y^2)^2} [/tex]
[tex] = \frac{2x^2y}{(x^2 + y^2)^2} [/tex].
Apart from the point of origin (0,0), this is continuous.
This means a unique solution exists in the region consisting of all points in the xy-plane except the origin.
the perimeter of a square is equal to the perimeter of an equilateral triangle the length of a side of the square is given by the x and lenghth of a side of equilaterel triangle is given x+1 which equation can be used to find the value of x?
Answer:
x = 3
Step-by-step explanation:
We are told that the length of a side of the square is x.
Now, perimeter of square = 4 × side length
Perimeter of square = 4x
Also,we are told that the triangle is equilateral and a side is (x + 1).
Thus, perimeter of triangle = 3(x + 1)
Since we are told that the perimeter of the square is equal to that of the equilateral triangle. Thus;
4x = 3(x + 1)
4x = 3x + 3
Subtract 3x from both sides to get;
4x - 3x = 3
x = 3
