The Factor analysis is a statistical method for analyzing the intercorrelations among various measures or test scores.

Factor analysis is a technique used to reduce a large number of variables to a smaller number of factors. This technique extracts the maximum common variance from all variables and puts them into the common score. This score can be used for further analysis as an index for all variables. A "factor" is a set of observed variables with similar response patterns. These are associated with hidden variables that are not directly measured (called noise variables). Factors are listed by their factor loadings, or the amount of variation in the data they can explain. There are two types: exploratory and confirmatory.

Yes, 64 a cube number.

64 is the cube of 4.

As, 4 x 4 x 4 = 64

The cubes are made up of values that are obtained by multiplying integers by themselves three or four times. The cube's original number can be found by raising any natural number to the power of three.

Cubes are the numbers that are produced when an integer is multiplied by itself three times. We can find cubes for any number, whether it be an integer or a fraction. In order for the cube of a whole number (x) to produce a perfect cube, the cube root of x3 must equal x. The procedure of locating cubes is thus the opposite of locating the cube root.

Answer:

f = 21

Step-by-step explanation:

since the rectangles are scaled copies then the ratios of corresponding sides are in proportion, scaled copy to original, so

[tex]\frac{f}{28}[/tex] = [tex]\frac{9}{12}[/tex] ( cross- multiply )

12f = 28 × 9 = 252 ( divide both sides by 12 )

The locations (0, 17) and are traversed by an exponential function of the type y = abx, where a and b are constants (2, 153). We can utilise these points to solve for the values of a and b in order to determine the equation of the exponential function.

Since we now know that y = abx when x = 0, we can change the first point to read as follows:

17 = a(b^0)

We can simplify this to: since anything raised to the power of 0 is 1,

17 = a

We can now determine b using the second point (2, 153):

153 = ab^2

By applying the formula:

153/a = b^2

taking square root

b = sqrt(153/a)

Substitute a = 17

b = sqrt(153/17)

The equation will now look like this when we add the value of a back in:

y = a * b^x

y = 17 * sqrt(153/17)^x

y = 17 * sqrt(9)^x

Consequently ,y = 17 * 3^x, is the exponential function that passes between the positions (0, 17) and (2, 153).

Therefore , the exponential function is y = 17 * 3^x .

The probability that a randomly chosen unsatisfactory screen came from Philips is approximately 0.4444.

What is probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Let's call the probability that a screen came from Philips "P".

know that 55% of the screens came from Corning Inc. and the rest came from Philips, so:

P = 1 - 0.55 = 0.45

We also know that the probability of getting an unsatisfactory screen from Corning Inc. is 1%, while the probability of getting an unsatisfactory screen from Philips is 4%:

P(unsatisfactory | Corning Inc.) = 0.01

P(unsatisfactory | Philips) = 0.04

Using Bayes' theorem, the probability that a randomly chosen unsatisfactory screen came from Philips can be calculated as:

P(Philips | unsatisfactory) = P(unsatisfactory | Philips) * P(Philips) / [P(unsatisfactory | Philips) * P(Philips) + P(unsatisfactory | Corning Inc.) * P(Corning Inc.)]

Substituting the values we have:

P(Philips | unsatisfactory) = 0.04 * 0.45 / [0.04 * 0.45 + 0.01 * 0.55] = 0.444444... or approximately 0.4444

Therefore, the probability that a randomly chosen unsatisfactory screen came from Philips is approximately 0.4444.

The probability that a randomly chosen unsatisfactory screen came from Philips is 46.48%.

Let's call P(Philips) the probability that a randomly chosen screen came from Philips, and P(Unsatisfactory | Philips) the probability that a screen is unsatisfactory given that it came from Philips. Then we can use Bayes' theorem to find P(Philips | Unsatisfactory), the probability that a screen came from Philips given that it is unsatisfactory.

Bayes' theorem states:

P(A | B) = P(B | A) * P(A) / P(B)

where A and B are events, P(A | B) is the conditional probability of A given B, P(B | A) is the conditional probability of B given A, P(A) is the probability of A, and P(B) is the probability of B.

In this case,

A = "the screen came from Philips"

B = "the screen is unsatisfactory"

So:

P(Philips | Unsatisfactory) = P(Unsatisfactory | Philips) * P(Philips) / P(Unsatisfactory)

We are given:

P(Unsatisfactory | Philips) = 4% = 0.04

P(Philips) = 45% = 0.45 (since 55% came from Corning Inc.)

P(Unsatisfactory) = P(Unsatisfactory | Corning Inc.) * P(Corning Inc.) + P(Unsatisfactory | Philips) * P(Philips)

= 1% * 55% + 4% * 45% = 0.55% + 1.8% = 2.35%

So:

P(Philips | Unsatisfactory) = 0.04 * 0.45 / 0.0235 = 46.48%

So the probability that a randomly chosen unsatisfactory screen came from Philips is 46.48%.

The zeros of a polynomial are the values of x that make the polynomial equal to 0.

To find the zeros, you need to set the equation equal to 0 and solve for x. The multiplicity of a zero is the number of times that the factor (x – zero) is a factor of the polynomial. To find the multiplicity of a zero, you need to find the highest power that x appears in the equation. For example, if the equation is (x-2)2•(x+1)3, then the zero is 2, and the multiplicity is 2.

The zeros of a polynomial are the values of x that make the equation equal to zero. The multiplicity of a zero is the number of times the factor (x - zero) occurs in the equation. To find the zeros and multiplicity of a polynomial, the polynomial needs to be factored into linear factors. The zeros are the x-intercepts of the equation (where the graph crosses the x-axis). The multiplicity is the power of the factor (x - zero). For example, if the equation is (x-2)^2(x-5), the zeros are x=2 and x=5 and the multiplicity of the zeros is 2 for x=2 and 1 for x=5.

The inverse of an inverse function is the original function.

For example, if a function f(x) has an inverse function g(x) such that f(g(x)) = x and g(f(x)) = x for all x in their respective domains, then the inverse of g(x) is f(x).

This is because when you apply the inverse function twice, it cancels out the effect of the inverse, and leaves you with the original function.

In mathematical notation, if f^-1(x) is the inverse of f(x), then (f^-1)^-1(x) = f(x)

So the inverse of an inverse is the original function, which means that (f^-1)^-1 = f

It's also worth noting that any function and its inverse are always one-to-one function, meaning that each element of the domain of the function corresponds to exactly one element of the range and vice-versa, which makes it possible to define an inverse function.

Four ways of solving an equation are Graphical, Elimination, Substitution, and Cross multiplication.

Graphical method: To solve linear equations graphically, first draw the graph for both equations in the same coordinate graph and locate the intersection point on the graph.

Elimination method: In this method, any of the coefficients is first eliminated by equating. After eliminating the coefficient, the equations are resolved to get the other equation. For example:

3x + 2y = 9 ———–(i)

x – y = 6 ———–(ii)

Here, if equation (ii) is multiplied by 3, the coefficient of “x” will become equal and can be eliminated.

So, multiply equation (ii) × 3 and then subtract equation (i)

3x + 2y - 9 - 3x-3y-18 = 0

y = -9/5

Now, put the value of y = 1.8 in equation (ii).

So, x – 1.8 = 6

x = 4.2

Substitution method: To solve a linear equation using this method, first, take the value of one variable separately from any of the equations. Then, substitute the value of this variable in the second equation and solve it.

Cross multiplication method: Linear equations can be easily solved using this method. This technique is used to simplify the solution. The following formula is used for solving 2 variable equation:

x /(b₁ c₂ − b₂ c₁) = y / (c₁ a₂ − c₁ a₁) = 1 /(b₂ a₁− b₁a₂)

The slope and y-intercept represent, time worked, x Wages earned,

In mathematics, the slope of a line is a measure of its steepness and direction. It is defined as the ratio of the "rise" (the change in the y-coordinate) to the "run" (the change in the x-coordinate) between two points on a line. The slope is often represented by the letter "m" and can be calculated using the formula:

m = (y2 - y1) / (x2 - x1)

The slope of a line can also be thought of as the coefficient of the x-term in the equation of the line in the form of "y = mx + b" where m is the slope.

From the table, we can see that the wages earned are directly proportional to the time worked. This is a linear relationship and we can find the equation of the line using the point-slope form.

The point-slope form of a linear equation is y - y1 = m(x - x1)

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

We can use the data from the table to find the slope of the line.

m = (y2 - y1) / (x2 - x1)

We can use the first two data points (x1 = 1, y1 = 9.25) and (x2 = 3, y2 = 27.75) to find the slope:

m = (27.75 - 9.25) / (3 - 1) = 18.5/2 = 9.25

Now we have the slope, we can use the point (x1 = 1, y1 = 9.25) to find the y-intercept, b

9.25 = 9.25 * 1 + b

we can find b is 0

So, the equation of the line in slope-intercept form is y = 9.25x + 0

The slope of the line, m = 9.25, represents the rate of change of the wages earned with respect to the time worked. It means that for every one-hour increase in time worked, the wages earned increase by $9.25. The y-intercept, 0, represents the wage earned when no time has been worked, which is 0$.
