Answer:
Private saving (Sprivate) is equal to disposable income minus consumption:
Sprivate = Y - T - C = 15,000 - 3,000 - 9,000 = 3,000
Public saving (Spublic) is equal to government revenue minus government spending:
Spublic = T - G = 3,000 - 3,600 = -600
National saving (S) is equal to the sum of private and public saving:
S = Sprivate + Spublic = 3,000 - 600 = 2,400
Investment (I) is given by the investment function:
I = 3,900 - 100r
Equating investment to national saving gives:
I = S
3,900 - 100r = 2,400
Solving for r:
r = 15%
Therefore, the equilibrium real interest rate is 15%.
Substituting r = 15% into the investment function gives:
I = 2,400
Therefore, investment is 2,400.
Finally, to determine if the government has a budget surplus or deficit, we need to calculate the government's budget balance, which is equal to government revenue minus government spending:
Budget balance = T - G = 3,000 - 3,600 = -600
Since the budget balance is negative, the government of Flatland has a budget deficit.

The difference between the adjustable-rate mortgage (ARM) and the fixed-rate mortgage is $176,494.80.
How to find the difference ?First, find the total amount paid on the adjustable-rate mortgage would be :
= ( 5 years x 12 months x 2, 506.43 payment ) + ( 10 x 12 x 3, 059. 46 ) + ( 5 x 12 x 3, 646.76) + ( 5 x 12 x 3, 630.65 )
= $ 1, 172, 971. 20
Then we can find the total payment for the fixed - rate mortgage :
= Monthly payment x Number of years
= 2, 767. 99 x 30 years x 12 months
= $ 996, 476. 40
The difference is:

Find the probability that a single randomly selected value is more than 979 dollars.
P(X > 979) = ???
Find the probability that a sample of size
is randomly selected with a mean that is more than 979 dollars.
P(M > 979) = ???
1. The probability that P(X > 979) = 0.567
2. The probability that P(M > 979) = 0.956
How do you calculate probability?
To calculate the probability that a single randomly selected value is more than 979 dollars.
979-1016
= -37/209
= -0.177
P(X > -0.177) = 0.5675
Therefore P(X > 979) = 0.568
To calculate that a sample of size is randomly selected with a mean that is more than 979 dollars.
209 / √94 = 21.557
-37/ 21.557 = -1.7164

For two programs at a university, the type of student for two majors is as follows. find the probability a student is a graduate student, given they are a history major.
The probability that a student is a graduate student given they are a history major is approximately 0.16.
What is probability?The likelihood or chance that an event will occur is quantified by probability. A number between 0 and 1, where 0 denotes that the occurrence is impossible and 1, denotes that the event is certain, is generally used to express it.
According to question:We are given the following information:
Total number of students who are history major: 463
Total number of graduate students: 261
Number of graduate students who are history major: 73
We can use the formula for conditional probability to find the probability that a student is a graduate student given that they are a history major:
P(graduate | history) = P(graduate and history)/P(history)
P(graduate | history) = 73/463
P(graduate | history) ≈ 0.1575 (rounded to the nearest hundredth)

Θ(x) = tan⁻¹(5x / (4(x - 13))), and Θ is maximized when the distance the cow must stand from the billboard x₀ = 26.
How to determine angle and distance?To find Θ, use similar triangles. Let the distance from the cow to the top of the billboard be h. Then, using similar triangles:
h / x = 5 / (x - 13)
Solving for h:
h = 5x / (x - 13)
The vertical angle subtended by the billboard at the cow's eye is equal to the angle whose tangent is given by:
tan(Θ) = h / 4
Substituting for h:
tan(Θ) = 5x / (4(x - 13))
To maximize Θ, find the value of x that maximizes tan(Θ). Taking the derivative of tan(Θ) with respect to x and setting it equal to zero:
d/dx (tan(Θ)) = 5(52 - 26x) / (4(x - 13))² = 0
Solving for x:
x₀ = 26
Substituting x₀ into the expression for Θ:
Θ(x₀) = tan⁻¹(5(26) / 4(13)) = tan⁻¹(5/2)
Therefore, Θ(x) = tan⁻¹(5x / (4(x - 13))), and Θ is maximized when x₀ = 26.

If the dealership you are buying the car from is offering 6.3% interest on a 5 year loan, what will your monthly payment be? How am I able to solve this when the selling price is $56,937.
Answer:
Step-by-step explanation:
To calculate the monthly payment on a loan, you can use the formula for the monthly payment on an annuity: P = (r * PV) / (1 - (1 + r)^(-n)), where P is the monthly payment, r is the monthly interest rate, PV is the present value of the loan (i.e., the amount borrowed), and n is the total number of monthly payments.
In this case, the amount borrowed is $56,937 and the interest rate is 6.3% per year. To convert this to a monthly interest rate, we divide by 12: r = 0.063 / 12 = 0.00525. The loan term is 5 years, so the total number of monthly payments is n = 5 * 12 = 60.
Substituting these values into our formula for the monthly payment, we get: P = (0.00525 * 56937) / (1 - (1 + 0.00525)^(-60)) ≈ $1102.53. So, the monthly payment on this loan would be approximately $1102.53.

Harrold is a dog walker. He walks 13 different dogs for the same distance around Greenpoint Park everyday. The park is a perfect square in shape. Harrold takes each dog for 1 full lap around the park. In one day Harrold will walk 6, 396ft all together. What is the length of 1 side of the park in yards.
Answer:
123 feet/41 yards
Step-by-step explanation:
When solving problems like this, we need to understand and note down what we already know to make our lives easier.
- He walks 13 different dogs
- the park is a perfect square
- he takes each dog for one full lap
- That day, he walked 6396ft
- He takes each dog the same distance
Now, let's find the unit value (how much ft does he walk if he takes JUST ONE dog around Greenpoint Park?)
Just divide: 6396 / 13 = 492 ft
Meaning, that when Harrold takes JUST ONE dog around the park, which is a perfect square, he walks 492 feet.
One full lap around the square shaped park is just 4 sides of the square.
So, he walks 492 ft every 4 sides.
However, the question specifically asked for one side.
Just divide again to get your answer:
492 / 4 = 123 ft
Therfore, the length of one side of the park is 123 feet, which is 41 yards.

13pi/6 terminal point
The terminal point of 13π/6 is (-√3/2, 1/2) by using unit circle.
What are the quadrants of a graph?The quadrants of a graph are the four sections that divide the coordinate plane. The quadrants are numbered in a counterclockwise direction starting from the positive x-axis.
1. Quadrant I is located in the upper-right section and contains points with positive x and y-coordinates.
2. Quadrant II is located in the upper-left section and contains points with negative x-coordinates and positive y-coordinates.
3. Quadrant III is located in the lower-left section and contains points with negative x and y-coordinates.
4. Quadrant IV is located in the lower-right section and contains points with positive x-coordinates and negative y-coordinates.
The quadrants are useful for determining the signs of coordinates, angles, and for plotting points on a graph.
To find the terminal point of 13π/6, we can start by recognizing that this angle is greater than 2π, which is one complete revolution around the unit circle.
To bring the angle back within one revolution, we can subtract 2π, which gives us 13π/6 - 2π/1 = 13π/6 - 12π/6 = 1π/6.
The angle 1π/6 is in the standard position between the positive x-axis and the first quadrant. The reference angle is π/6, which is the angle between the terminal side and the x-axis.
Since the angle is in the 2nd quadrant, the x-coordinate will be negative and the y-coordinate will be positive. Using the unit circle, we can find the values of sine and cosine at π/6 and then negate the value of cosine since the angle is in the second quadrant.
cos(π/6) = √3/2
sin(π/6) = 1/2
Therefore, the terminal point of 13π/6 is (-√3/2, 1/2).
