A $50,000 car with a 30% ($15,000) residual value is financed over five years. In this case, the loan is repaid in full in five years for $35,000, with the final $15,000 being paid as a balloon payment.

In statistical or machine learning models, the differences between actual and expected data values are referred to as residuals.

They act as a diagnostic instrument for assessing the caliber of a model. They are also known as errors.

The primary column, Inflation, of the table below provides details on US inflation for each month of 2017. Forecasts from a model that seeks to predict the rate of inflation are shown in the Predicted column.

Following are the calculations for the residuals: Residual is equal to predicted inflation.

The Residual column contains them.

The model predicted 1.8% for the data for January 2017, while the actual inflation rate was only 0.5%, leaving a residual of -1.3%.

Hence, A $50,000 car with a 30% ($15,000) residual value is financed over five years. In this case, the loan is repaid in full in five years for $35,000, with the final $15,000 being paid as a balloon payment.

Compare to last year the population of the Boom town increased by 25%  which is equal to 6000 then population of the last year is 4800.

As given in the question,

Present year population of the Boom town is equal to 6000

Let us consider 'y' be the population of Boom town last year.

Percentage of increase in population = 25%

Equation formed for the given condition is :

y + 25%y = 6000

⇒ y + (25/100)y = 6000

⇒ (100 + 25 / 100 )y = 6000

⇒ y  =  ( 600,000 / 125 )

⇒ y  = 4,800 population of Boom town last.

Therefore, last year population of the Boom town is equal to 4,800.

Step-by-step explanation:

The zeroes of the polynomial x5-x3+2x-2 are 0.618033988749895 and -1.618033988749895.

The given polynomial is x5-x3+2x-2. To find the zeroes of the polynomial, it should be set equal to zero.

Thus, x5-x3+2x-2 = 0

To solve this equation, the quadratic formula can be used. The quadratic formula is x = [-b ± √(b2 - 4ac)]/2a.

In this equation, a = 1, b = -1 and c = -2.

Thus, x = [-(-1) ± √((-1)2 - 4(1)(-2))]/2(1)

x = [1 ± √5]/2

The zeroes of the equation are

x = 0.618033988749895 and x = -1.618033988749895

Therefore, the zeroes of the polynomial x5-x3+2x-2 are 0.618033988749895 and -1.618033988749895.

The length of  the outside arc of each piece compared to the inside arc is 5.57 inches

Length of outer track = sum of length of 10 pieces = circumference of the outer circle

if R is the Radius of outer circle then...

Circumference of the outer track = 2pi*R

Similarly the circumference of the inner track (with radius r) = 2pi*r

length of each outer piece is 3.5 inch more than length of inner piece

So total outer length is 10*3.5 =35 inches more than the inner length.

=> Outer Circumference - Inner Circumference = 35 inches

=> 2pi*R - 2pi*r = 35

=> 2pi(R -r) = 35

=> R-r = 35/2pi = 5.57 inches

What is linear equation ?

Linear equation can be defined as equation in which highest degree is one.

In order to determine the equation for this relationship, we need to first find the slope between these two values. There are two ways to do this:

1. Create a graph

*Create a graph with the x-axis representing the years past 2000 (so 2000 would be 0 and 2003 would be 3 and so on)

*Use the fact that slope=rise/run to get slope=2.7/3 (because we rise 87-84.3=2.7 and run 3 (from 2000 to 2003), and 2.7/3=27/30=9/10

*Plug this and the point (0, 84.3) into the formula y=mx+b to find the y-intercept of your equation

--> 84.3=(9/10)(0)+b --> b=84.3

So, your equation can be written now as y=(9/10)x+84.3

[Note: To check, if you plug in 3 you should get 87, and you do, so it works!]

2. Use the slope formula

Alternatively, you could have did slope=(y2-y1)/(x2-x1)=(87-84.3)/(3-0)=2.7/3=9/10

The process here would be the same as above

b) Here, just plug 10 into the equation above (since 10 is the number of years 2010 is after 2000, or 2010-2000=10). Doing this we get:

y=(9/10)(10)+84.3=9+84.3=93.3

So, in 2006 we have 93.3 people per sq mile

Therefore, In 2006 we have 93.3 people per sq mile .

It is not possible to determine which system of inequalities is shown without a graph or more information about the inequalities. Without a graph, it is not possible to determine the region that is being represented by the system of inequalities. Additionally, without more information about the inequalities, it is not possible to determine which inequality is the upper bound and which is the lower bound. Therefore, the answer is "not enough information."

The solution of the system of inequalities is,

Taking the subject A and solving the equation, the resultant value of A will be 1,150.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

So, we have the equation:

4/5*A=920

Now, calculate the equation taking A as the subject:

4/5 * A = 920

4A  = 920 * 5

4A = 4,600

A = 4,600/4

Two or more inequalities in one or more variables make up a system of inequalities. When a problem calls for a variety of answers and those answers are constrained by multiple factors, systems of inequalities are used.

The intersection region of every solution in the system of inequalities is the system's solution.

Comparable to solving a system of linear equations, solving a system of linear inequalities involves locating the point (or points) of intersection, however this is not the case with inequalities. Instead, the area that fulfils each linear inequality will make up the solution set.

In slope-intercept form, the equation of a line is represented as y = mx + b. So the equation in slope-intercept form is y = (1/2)x + 2

Slope is a measure of the steepness of a line or a linear function. It is often represented by the letter "m" and is calculated as the ratio of the change in the y-coordinates of two points divided by the change in the x-coordinates of those same two points. In other words, it is the ratio of the "rise" to the "run" of the line. The slope of a line can be positive, negative, zero, or undefined.

The slope-intercept form of a linear equation is a way to represent the equation of a line in the form of y = mx + b, where m is the slope and b is the y-intercept of the line. The y-intercept is the point where the line crosses the y-axis, and it is represented by the value of b. This form of the equation is useful because it allows us to easily identify the slope and y-intercept of a line, as well as to graph the line using these values.

The first step is to add 12y to both sides:

The probability of being a senior citizen and white is: (0.63)(0.3) = 0.189.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty.

Given that the probability of identifying white is 0.63.

Then the probability of not white is:

The solution to the implicit differentiation problem is dy/dx = -16x/2y.

To solve this problem, we must use implicit differentiation. This means that we must differentiate both sides of the equation with respect to the independent variable, x. We can do this by taking the derivative of both sides of the equation.

The derivative of 8x^2 is 16x and the derivative of y^2 is 2y dy/dx.

Therefore, the equation becomes: 16x + 2y dy/dx = 0

We can then solve for dy/dx by dividing both sides by 2y, which gives us dy/dx = -16x/2y.
