The ratios of (a) square kens to square meters (1 ken² / 1 m²) is 3.88
For given question,
We have been given the unit conversion.
A traditional unit of length in Japan is the ken
and 1 ken = 1.97 m
We need to find the the ratios of (a) square kens to square meters.
First we find the square of 1 ken.
⇒ 1 square kens = (1.97 m)²
⇒ 1 square kens = 1.97 × 1.97 m²
⇒ 1 square kens = 3.88 m² ..................(1)
And 1 square meters = 1 m² ................. (2)
Now we take the ratio of square kens to square meters.
From (1) and (2),
⇒ 1 ken² / 1 m² = 3.88 / 1
⇒ 1 ken² / 1 m² = 3.88
Therefore, the ratios of (a) square kens to square meters (1 ken² / 1 m²) is 3.88

Using the function concept, we have that:
Items 1, 4, 5, 6, 8 and 10 are functions.Items 2, 3, 7 and 9 are not functions.When does a relation represents a function?A relation represents a function when each value of the input is mapped to only one value of the output.
For the relations that are not functions, we have that:
Relation 2: Suppose x = sqrt(5), then y = 2 or y = -2, that is, for each value of x, there are two values of y associated with it, hence it is not a function.Relation 3: Input 3 is associated with outputs 4 and 2, hence it is not a function.Relation 7: Input 9 is associated with outputs -18 and 17, hence it is not a function.Relation 9: Input 9 is associated with outputs -16 and 9, hence it is not a function.More can be learned about relations and functions at https://brainly.com/question/12463448

Sometimes we ask you to enter an equation and not just an expression. find an equation of a line that has slope 8 and passes through the point (3, 11).
The equation of the straight line is 8x - y = 85.
It is given that the slope of the line is 8 and passes through the point (3,11).
We have to find the equation of the line.
We know that,
Equation of a line is :-
[tex]y -y_1 = m (x - x_1)[/tex]
Where,
x and y are variables
m is the slope of the line
[tex](x_1,y_1)[/tex] are the coordinates of the point that passes through the line.
Here,
[tex](x_1,y_1)[/tex] = (3,11)
m = 8
Hence,
Equation of the line = y - 3 = 8(x - 11)
y - 3 = 8x - 88
8x - y = -3 + 88
8x - y = 85

Scientific notation of given expression = 7.247× 10⁶
What is scientific notation?Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
For example,
650,000,000 can be written in scientific notation as 6.5 ✕ 10⁸.
Given expression
(7.26x10⁶)-(1.3x10⁴)
It can be written as
= (7.26×1000000) - (1.3 × 10000)
= 7260000 - 13000

Solve the recurrence relation: t(n) = 3t(n-1) 1, with initial condition of t(0) = 1
A linear recurrence relation is a function or sequence in which each term is a linear combination of the terms that came before it.
The recurrence relation exists [tex]$T(n)=\Theta\left(3^n\right)$[/tex].
What is meant by "recurrence relation"?Recurrence relations are used to simplify complex problems by reducing them to an iterative process based on simpler versions of the problem.
Using the substitution method, we find out that
[tex]T(n) &=n+3 T(n-1) \\[/tex]
[tex]&=n+3(n-1)+3^2 T(n-2) \\[/tex]
[tex]&=n+3(n-1)+3^2(n-2)+3^3 T(n-3) \\[/tex]
[tex]&=\cdots \\[/tex]
[tex]&=n+3(n-1)+3^2(n-2)+\cdots+3^{n-1}(n-(n-1))+3^n T(0) \\[/tex]
simplifying the above equation, we get
[tex]$&=\frac{3^{n+1}-2 n-3}{4}+3^n T(0) \\[/tex]
[tex]&=\Theta\left(3^n\right)[/tex]
Even without doing the full calculation it is not hard to check that [tex]$T(n) \geq 3^{n-1}+3^n T(0)$[/tex], and so [tex]$T(n)=\Omega\left(3^n\right)$[/tex].
A cheap way to obtain the corresponding upper bound is by considering
[tex]$S(n)=T(n) / 3^n$[/tex], which satisfies the recurrence relation
[tex]$S(n)=S(n-1)+n / 3^n$[/tex].
Repeated substitution then gives
[tex]$\frac{T(n)}{3^n}=\sum_{m=1}^n \frac{m}{3^m}+T(0)[/tex]
Since the infinite series [tex]$\sum_{m=1}^{\infty} \frac{m}{3^m}$[/tex] converges, this implies that [tex]$\frac{T(n)}{3^n}=\Theta(1)$[/tex] and so [tex]$T(n)=\Theta\left(3^n\right)$[/tex]
Therefore, the recurrence relation exists [tex]$T(n)=\Theta\left(3^n\right)$[/tex].

Suppose that the ratio of males to females in the sales field of a large company is 4:5. if there
are 81 sales representatives in the company, how many are male and how many are female?
There are 36 males and 45 females in the sales field.
Ratio of the number:
Ratios compare two numbers, usually by dividing them.
For example,
If you are comparing one data point (A) to another data point (B), your formula would be
=> A/B.
This means you are dividing information A by information B.
Given.
Suppose that the ratio of males to females in the sales field of a large company is 4:5.
Total number of representatives = 81.
Now, we need to find the number of males and number of females.
Let x be the number of representatives.
So, based on the ratio we have written this as,
=> 4x : 5x = 81
So, the total number of representatives is,
=> 4x + 5x = 81
=> 9x = 81
=> x = 81/9
=> x = 9
So, the number of males is
=> 4x => 4(9) = 36
And the number of females is,
=> 5x => 5(9) = 45
Therefore, there are 36 males and 45 females in the sales field.

The mean of this data was found to be 42, while the median was 37. what does this tell you about the shape of this distribution?
Mean > median, the distribution is skewed to the right.
What is mean?In mathematics, particularly statistics, there are several types of means. Each mean is used to summarize a specific set of data, often in order to better understand the overall value (magnitude and sign) of a given data set.The arithmetic mean, also known as "arithmetic average," of a data set is a measure of the central tendency of a finite set of numbers: specifically, the sum of the values divided by the number of values.So,
Given that age was documented in a survey of 8225 Americans.The mean was 42, and the median was 37.As a result, the median mean is used here.When the mean exceeds the median, we can say that the data is skewed to the right.If the mean is symmetrical, the median will coincide. If the mean differs from the median, the data is skewed rather than symmetrical.When mean > median, we have a skewed distribution to the right.Therefore, mean > median, the distribution is skewed to the right.

Testing for within × within and between × within moderation using random intercept cross-lagged panel models "allow measurement decomposition into between- & within components and have thus are becoming famous for testing developmental hypotheses."
What is cross-lagged panel models?Cross lagged panel design is a form of structural equation model in which data is gathered at a number of points in time. It is primarily used to assess causal relationships (which may be bi-directional) in a non-experimental setting, where variables are not controlled but simply recorded.
According to cross-lagged panel design analysis:
If rX1Y2 is'significantly different' from zero, we can draw the conclusion that X is the cause of Y.If rX2Y1 is significantly distinct from zero, we can deduce that Y is the cause of X.If they are both substantially different from zero, we deduce that X causes Y and Y causes X. If they are both equal, we reach the conclusion that they do not cause each other but instead are both affected by a third variable.If we understand that X and Y are correlated but with us data shows no conclusive correlation (neither rX1Y2 or rX2Y1 are significantly different from zero), it is possible that our time lag was just too short (or too long) to enable causal influences to operate, and we need to redesign our experiment.
