Which graph represents an exponential decay function?

In JMP, open the data in Fit Model and choose scatterplot, and a residual usually looks like the scatterplot but more extended vertically.

(a): Yes, because there is not much of a trend in the data.

(b): The materials cost is a very small percentage of the average cost. It could be true that items that use fewer materials take more labor hours to make ready for the customer.

(c): chose a correct residual plot

In JMP, in the top red triangle, click on save columns, and then click on Residuals. Then go to the data table in JMP and in Graph, press GRAPH BUILDER... put residuals on y and # of labor hours on x

As the number of labor hours​ increases, the residual values from the regression also tend to​ increase, suggesting that the labor input is a lurking variable.

The amount to save according to the recommendation of 3/10 of income is $17400.

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom. The denominator specifies the total number of equal parts in the whole, whereas the numerator specifies the number of equal parts that were taken.

Given that the amount made in a year is $58,000.

The recommended savings is 3/10 thus:

(58000) (3/10) = 17400

Hence, according to the recommendation the amount that needs to be saved in one year is, $17400.

Given f ( x ) = 4 − ( x + 3 )^5, find f(3).

The values for x at which f has a relative maximum are -3 and 4.

A relative maximum is a point on a function where the function has the highest value within a certain interval or region. It is a local maximum, meaning that it is the highest value within a certain interval, but it may not be the highest value overall.

For example, a function may have multiple relative maxima but only one global maximum.

It's important to note that a relative maximum is not always an actual maximum, it's only a maximum in a specific interval or region of the function.

It's also important to note that for some functions, there might not be any relative maximum in the interval or domain where the function is defined, and for others, it might have a relative maximum at the endpoint of the interval.

On plotting the zeroes of the f(x) on the number line we observe the value of the derivative of f(x) changes from positive to negative indicating points of relative maximum.

Therefore, The values for x at which f has a relative maximum are -3 and 4.

We can only say that X+y=21 is a true statement for any values of X and y that satisfy this equation.

In mathematics, elimination is the process of solving a system of equations by eliminating variables. Elimination involves two steps: first, a variable is chosen to be eliminated and then the coefficients of the variable are used to modify the remaining equations so that they contain only the other variables.

To solve for the unknown variables, we can use the following methods:

Graphing: We can graph the equation on a coordinate plane by plotting the line of the equation. The point of intersection of the line with the x and y-axis represents the solution of the system of equations.

Substitution: We can solve for one variable in terms of the other by isolating one variable and substituting it into the other equation.

Elimination: We can eliminate one variable by adding or subtracting the equations to eliminate one of the variables.

In this case, we don't have any other equation to solve the system, so we can not find a unique solution, we can only say that X+y=21 is a true statement for any values of X and y that satisfy this equation.

Answer: To solve for all values of x in the equation x^2 - 2x - 48 = 0 by completing the square, we can follow these steps:

Bring the x term to one side of the equation by adding 2x to both sides: x^2 - 2x = 48

Divide the coefficient of the x^2 term (which is 1) by 2 and square it to find the value to add to both sides of the equation to complete the square: (1/2)^2 = 1/4. Add 1/4 to both sides of the equation: x^2 - 2x + 1/4 = 48 + 1/4

Take the square root of both sides of the equation: (x - 1)^2 = 192 + 1

Solve for x by taking the square root of both sides of the equation: x - 1 = ± √193

Add 1 to both sides of the equation to find the values of x: x = 1 ± √193

So the solutions of the equation are x = 1 + √193 and x = 1 - √193

It is important to notice that these are the solutions in radical form, so they are not exact values of x.

Jennifier was paid $1.49 for each shirt, $4.99 for each pair of slacks and $7.99 for each sports coat.

Two or more expressions with an Equal sign is called as Equation.

Let x = shirts, y = slacks, z = sports coats.

Set up your systems of equations equations.

3x+2y=$14.45..(1)

6x+2y+z=$26.91...(2)

4x+2z=$21.94...(3)

From equation 2

$14.45+3x+z=$26.91

3x+z=12.46...(4)

Multiply equation 4 with 2

6x+2z=24.92..(5)

6x+2z-4x-2z=24.92-21.94

2x=2.98

Divide both sides by 2

x=$1.49

Now plug in x value in equation 1.

3(1.49)+2y=$14.45

4.47+2y=14.45

2y=9.98

Divide both sides by 2

y=$4.99

4x+2z=$21.94

4(1.49)+2z=21.94

5.96+2z=21.94

2z=21.94-5.96

2z=15.98

Divide both sides by 2

z=$7.99

Hence, Jennifier was paid $1.49 for each shirt, $4.99 for each pair of slacks and $7.99 for each sports coat.

A response variable, also known as a dependent variable, is a variable that is being studied or measured in an experiment or statistical analysis. It is the outcome or output of the study, and its value is influenced by one or more predictor variables, also known as independent variables.

The goal of a study is often to understand how the response variable is affected by the predictor variables.

For example, in a medical study, the response variable might be the level of a certain protein in the blood, and the predictor variable might be the dosage of a new drug being tested.

The square root of 6^2 (√6²) is 6.

What is square root?

Square root of a number is a value, which on multiplication by itself, gives the original number. The square root is an inverse method of squaring a number. Hence, squares and square roots are related concepts.

Suppose x is the square root of y, then it is represented as x=√y, or we can express the same equation as x^2 = y. Here, ‘√’ is the radical symbol used to represent the root of numbers. The positive number, when multiplied by itself, represents the square of the number. The square root of the square of a positive number gives the original number.

For example, the square of 3 is 9, 32 = 9 and the square root of 9, √9 = 3. Since 9 is a perfect square, hence it is easy to find the square root. But for an imperfect square like 3, 7, 5, etc., we have to use different methods to find the square root.

Equation of parallel line = y = 3x + 2 and equation of perpendicular line 3y = -x + 16, passing through the point (1,5).

(a) To find an equation of the line that passes through the point (1,5) and is parallel to the line y = 3x - 5, we need to use the slope of the given line. The slope of a line is represented by m and it is equal to the coefficient of x. In this case, the slope of the line y = 3x - 5 is 3.

Therefore, the slope of the line that is parallel to y = 3x - 5 is also 3.

We can use the point-slope form of a line, which is:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line and m is the slope.

Substituting the given point (1, 5) and the slope of 3, we get:

y - 5 = 3(x - 1)

Simplifying the equation, we get:

y = 3x + 2

So, the equation of the line that passes through the point (1, 5) and is parallel to the line y = 3x - 5 is y = 3x + 2

(b) To find the slope of a line that is perpendicular to the line y = 3x - 5, we need to take the negative reciprocal of the slope. The negative reciprocal of 3 is -1/3. So, the slope of a line that is perpendicular to y = 3x - 5 is -1/3

We can use the point-slope form of a line, which is:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line and m is the slope.

Substituting the given point (1, 5) and the slope of -1/3, we get:

y - 5 = -1/3(x - 1)

Simplifying the equation, we get:

3(y - 5) = -x + 1

3y = -x + 16

So, the equation of the line that passes through the point (1, 5) and is perpendicular to the line y = 3x - 5 is 3y = -x + 16

m^2 = (x+y+z)(x^2+y^2+z^2-xyz).

We can substitute the original equation back in to get

m^2 = (x+y+z)\frac{m^2}{n}.

Then, we can divide both sides of the equation by (x+y+z) to get m^2 = \frac{m^2}{n}. Finally, we can solve for m+n by multiplying both sides of the equation by n, which gives us m+n = m^2.
