Regression without parameters using smoothing splines A scatterplot's data is smoothed by fitting a smooth curve to it. Will initially concentrate on two variable issues: OneX Yand Will eventually include more than two predictors. Our example: Where "1; "1;::: "are independent from me," yi=f(xi) + I.

The appealing, adaptable, and widely-used method of non-parametric regression uses cubic splines for curve estimation. Although the fundamental concept was developed many years ago, the approach is maybe not as well recognized or used as it could be. This paper's topics and examples are meant to increase comprehension and broaden the applicability of the spline smoothing technology. The fundamentals of the method, its relationship with moving averages and other smoothing techniques, the automatic selection of the degree of smoothing, and the use of residuals for model adaption and diagnostic testing are just a few of the specific topics covered. A finite-dimensional Bayesian framework is used to address the issue of offering inference areas for curves and for pertinent curve attributes.

According to the given information The highest 10% of the population's IQ is 0.0179.

The root of the variability in the given group as well as ungrouped data is referred to as the standard deviation. The standardized value is the value left after subtracting the mean and dividing by the standard deviation.

z =   (x- μ) / σ

x denotes the observations (a specific value that you are calculating the z-score for).

Mu(μ) is the mean.

Sigma(σ) denotes the standard deviation.

x = 131.5

μ = 200

σ = 15

So, when humans apply the values to the formula, we obtain,

=> z = 131.5 - 100 /15

=> z = 2 .10

Using table A-2, calculate the corresponding probability:

=> P(Z>2.10) = 1 − P(Z<2.10)

=> 1 − 0.9821

=> 0.0179

The top 10% of the population has a required IQ of 0.0179.

The student is wrong in the steps of the factorization.

Factorization of polynomials, also known as polynomial factorization, is a mathematical and computer algebraic technique that combines irreducible factors with coefficients in the same domain to produce a polynomial with coefficients in a particular field or in integers.  A polynomial with coefficients in a certain field or in integers is expressed as the product of irreducible factors with coefficients in the same domain in mathematics and computer algebra, which is known as polynomial factorization.  A polynomial can be expressed as the product of its factors, where the components must have a degree that is less than or equal to the original polynomial.

The equation is given as:

x^2  + 2 x - 48 = 0

Expand the equation

x^2 + 8x - 6x - 48 = 0

Factorize the equation

x(x + 8)- 6(x + 8)

Factor out x + 2

(x + 8)(x - 6) = 0

The above means that the factored equation of x^2 + 2x - 48 = 0 is (x + 8)(x - 6) = 0

Answer:

Step-by-step explanation:

A, because the slope 3 is larger than a slope of 1.

Equation A's line is steeper than equation B's line because it has a higher slope.

To determine which equation's line is steeper, we need to compare their slopes. In both equations, the coefficients of the x term represent the slope of the line.

Let's first rewrite both equations in slope-intercept form, which is of the form y = mx + b, where "m" is the slope and "b" is the y-intercept:

A. y = 3x + 7

B. y = x + 9

In equation A, the coefficient of x is 3, which means the slope of the line is 3.

In equation B, the coefficient of x is 1, which means the slope of the line is 1.

Now, to compare the slopes, we can see that the slope of equation A (3) is greater than the slope of equation B (1).

This means that the line represented by equation A is steeper than the line represented by equation B.

Hence, equation A's line is steeper than equation B's line because it has a higher slope.

The solution for x and y for the given expression are :

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the given equation is : 16x + 9 = 9y - 2x

Now,

solving for x :

16x+9=9y−2x (Add 2x to both sides.)

16x+9+2x=−2x+9y+2x

18x+9=9y

18x+9+−9=9y+−9 (Add -9 to both sides)

18x=9y−9

18x/18 = 9y−9/18 (Divide both sides by 18.)

x =1/2y + −1/2

solving for y :

16x+9=9y−2x

−2x+9y=16x+9 (Flip the equation.)

−2x+9y+2x=16x+9+2x (Add 2x to both sides.)

9y=18x+9

9y/9=18x+9/9 ( Divide both sides by 9.)

y=2x+1

Therefore, the solution for x and y for the given expression are :

x =1/2y + −1/2 and y=2x+1 respectively.

Given that x = 8, y = 2, and z = 3, the equation 2x = 3yz is false.

An expression is a number, variable or the combination of both put together by operation symbols while an equation is a statement that shows that two expressions are equal and is separated by an equal sign "=".

To check if the equation 2x = 3yz is true when x = 8, y = 2, and z = 3, plug in or substitute the value of each variable to the equation and evaluate.

2x = 3yz

2(8) = 3(2)(3)

16 ≠ 18

Since 16 is not equal to 18, the given values do not satisfy the equation, then the statement is not true.

Answer:

There were 248 adult tickets and 248 kid tickets.

Step-by-step explanation:

a = number of adult tickets

k = number of kid tickets

a + k = 524                                 10a + 5k = 3860

Multiply the equation on the right all the way through by -5 so that we can eliminate the k's when we add the equations together.

-5(a+ K) = 524(-5)

-5a - 5k = -2620

Add the two equations together:

-5a - 5k = -2620

10a + 5K = 3860

5a           = 1240  Divide both sides by 5

a = 248  There are 248 adult tickets.  Plug in 248 for a in either of the original equations.

a + k = 524

248 + k = 524  Subtract 248 from 524 to find the number of kid tickets.

There are 276 kid tickets.

Check:

Plug in 276 for k and 248 for adult to both equations to see if they work

a + k = 524

248 + 276 = 524

524 = 524

10a + 5k = 3860

10(248) + 5(276) = 3860

2480 + 1380 = 3860

38060 = 3860

The value of A is 35.

The given expression is as follows:

sin A = cos (A + 20)

using trigonometric rule,

sin A = cos(90 - A)

Therefore,

cos (A + 20) = cos(90 - A)

divide both sides by cos

Hence,

A + 20 = 90 - A

A + A = 90 - 20

2A = 70

divide both sides by 2

A = 70 / 2

A = 35

Therefore, the value of A is 35.
