true or false, we can compare a model to before using a transformation on x or y to a model after using a transformation by using the corresponding values of sse.
True, we can compare a model before using a transformation on x or y to a mode before using a transformation by using the corresponding values of the sum of squares error SSE.
For example, to compare two models, one of which has a transformation on the outcome of the variable, that is:
First model[tex]y=x+z[/tex]
Second model:[tex]y^{1/k} =x+z[/tex]
The best logical approach might be to look at the comparative performance obviously with predicted transformed values back-transformed and then look at the models sum of squares error of these predictions. It has to be random predictions and comparisons because the error distributions are also transformed.

By evaluating the exponential equation we will see that:
a) On 2001 the population is 150.38 thousands.
b) on 2018 the population is 409.13 thousands.
How to estimate the population in 2001?We know that the population (in thousands) x years after 1998 is given by the exponential equation:
y = 123.1*(1.069)^x
a) We want to find the population in 2001, this is 3 years after 1998, so x = 3, replacing that we will get:
y = 123.1*(1.069)^3 = 150.38
So the population on 2001 will be 150.38 thousands.
b) If the equation still works for 2018, then we can use x = 20 (2018 is 20 years after 1998) then the population will be:
y = 123.1*(1.069)^18 = 409.13
So the population is 409.13 thousands.

What is mensuration ?Mensuration is a division of mathematics that studies geometric figure calculation and its parameters such as area, length, volume, lateral surface area, surface area, etc. It outlines the principles of calculation and discusses all the essential equations and properties of various geometric shapes and figures.
Mensuration is a subject of geometry. Mensuration deals with the size, region, and density of different forms both 2D and 3D. Now, in the introduction to Mensuration, let’s think about 2D and 3D forms and the distinction between them.
CalculationThe rate of change of volume will be the product of the rate of change of radius and the area of the sphere. The area of the sphere is ...
A = 4πr² = 4π(6 ft)² = 144π ft²
Then the relationship above is ...
dV/dt = A·dr/dt
548 ft³/s = (144π ft²)·dr/dt
dr/dt = (548 ft³/s)/(144π ft²) = 137/(36π) ft/s ≈ 1.2113 ft/s

As per the question statement, we are provided with a set of values [1/3, 0.3, 33%, 8/25, 33.6%],
And we are required to rearrange the above mentioned set in the ascending order of magnitude.
To answer this question, we will have to convert all the values into fractions with a common denominator, and then arrange the fractions in an ascending order of magnitude of their numerators to obtain our desired answer, that is,
[(1/3) = 0.33333333...]
[(0.3) = (3/10) = (30/100)],
[(33%) = (33/100) = 0.330],
[(8/25) = (32/100) = 0.320]
And, [33.6% = (33.6/100) = 0.336]
Since (0.336 > 0.333 > 0.330 > 0.320 > 0.300),
Therefore, rearranging [1/3, 0.3, 33%, 8/25, 33.6%] in the ascending order of magnitude, we get, [33.6%, (1/3), 33%, (8/25), 0.3]

3 years ?
The amount of money (principal) that Hsu-Mel would need to invest in an account now with 7.4% APR, compounded daily, in order to reach her goal in 3 years is $7206.24.
How to determine the principal amount?Mathematically, compound interest can be calculated by using this formula:
A(t) = P(1 + r/n)^{nt}
Where:
A represents the future value.P represents the principal.r represents the interest rate.n represents the number of times compounded.T represents the time measured in years.Note: The annual percentage interest (APR) rate would be divided by 365 since it is compounded daily.
Substituting the given parameters into the formula, we have;
9,000 = P(1 + 0.074/265)^{365 × 3}
9,000 = P(1.00023)^{1095}
9,000 = P(1.2489)

For each direct variation, find the constant of variation. Then find the value of y when x = -0.5.
21. y =4 when x = 0.5
22. y =2 when x = 3
When x = -0.5, the value of y is -0.33. When y varies directly with respect to x, the equation y = kx is used. where k is the constant of proportionality
What is meant by variation?A variation is a relationship between one set of values for one variable and another set of values for another variable. Variation in direct. If m is a nonzero constant and b = 0, then the function y = mx (often written y = kx) is a direct variation of the equation y = mx + b. Variation is defined as differences in an individual's genetic constituents that result in differences in the physical appearance of individuals living in a population. Individuals differ in their physical appearance, fertility, metabolism, and mode of reproduction.The average of the squared deviations from the mean is defined as variance.Therefore,
When X equals 3, Y equals 2.
We solve for k by plugging in 3 for x and 2 for y.
y = kx \s 2 = k(3) (3)
Subtract 3 from both sides.
2/3 = k
Now we plug in 2/3 for k
y = 2/3 x
Given x = -0.5 simplifying we get,
y = 2/3 (-0.5)
y = -0.33
Hence, the value of y is -0.33 when x = -0.5

A mathematical statement proving the equality of two mathematical expressions is the essence of an equation. For example, 8x + 3 = 12 is an equation in which the expressions 8x + 3 and 12 are separated by a 'equal' sign.
The system of equations that could be used to determine the number of commercials and the number of movies on which Marques songs were played is illustrated as 30(x + 5) + 120(x) = 900.
The variable x represents the number of times the song has been played in movies.
According to the information, Marques is a songwriter who collects royalties on his songs whenever they are used in a commercial or a movie, and she will earn $30 every time one of his songs is used in a commercial, while he will earn $120 every time one of his songs is used in a movie.
Let x be the number of times the song was heard in movies.
Marques' songs were heard in five times more commercials than in movies. x+5 will be the answer.
As a result, the equation to solve the problem will be:
30(x + 5) + 120(x) = 900
30x + 150 + 120x = 900
150x + 150 = 900
150x = 900 -150
150x = 750
x = 750/150
x = 5
Number of movies = 5
Number of commercial = x + 5
5 + 5 = 10
Therefore Marques played songs in Number of movies = 5 and Number of commercials = 10

You are buying 3 shirts and 2 pairs of pants. You spend $300. Let x represent the price of the shirt and y represent the price of the pants.
Let
x ----> the price of the shirt
y ---> he price of the pants
we have that
The price of three shirts plus the price of two paints must be equal to $300
so 3x+2y = 300 this is the equation of the line in standard form
Convert to slope intercept form
y = mx+b
Isolate the variable y
3x+2y = 300
subtract 3x both sides
3x+2y-3x = -3x+300
2y = -3x+300
Divide by 2 both sides
y = -1.5x+150
----> equation of the line in slope intercept form
Find out the x-intercept
Remember that the x-intercept is the value of x when the value of y is equal to zero
In this problem, the x-intercept is the price of the shirt when the price of the paints is equal to zero
Using the Standard Form, identify the x-intercept of the graph
The standard form is
Ax+By = C
The x-intercept is C/A
we have
3x+2y = 300
so
300/3 = 100
The x-intercept is the point (100,0)
That means---> The price of the shirt is $100 when the price of the paints is equal to $0
Alternative method to find out the x-intercept (equation in slope intercept form)
y = -1.5x+150
For y=0
0 = -1.5x+150
solve for x
1.5x = 150
x = $100
Hence the x-intercept is the point (100,0)
