what is the main purpose of efa? group of answer choices find out the relationship between variables. catch the idea of the late

zzz [600]

The main purpose of EFA is to find out the relationship between variables.

EFA is an abbreviation for exploratory factor analysis, which is used to determine the link between variables that are assessed.
Exploratory factor analysis is a statistical tool used in multivariate statistics to find the underlying structure of a rather large set of variables. EFA is a factor analysis approach with the overriding purpose of identifying the underlying connections between measured variables.
The common factor concept underpins EFA. Manifest variables are expressed as a function of common components, unique factors, and measurement errors in this model. Each distinct component has an effect on only one manifest variable and does not explain relationships between manifest variables. Common factors impact several manifest variables, and "factor loadings" are measurements of a common factor's influence on a manifest variable.

Calculate the length of AB. Round to the nearest tenth.

marissa [1.9K]

Answer:

AB = 10.06 cm

Step-by-step explanation:

Consider the given figure,

We have to find the length of side AB.

Lets rename the figure first, ABCD forms a rectangle. So , CB = DA = 12 cm

Also, EA = ED +DA ⇒ 15 = ED + 12 ⇒ ED = 15 - 12 ⇒ ED = 3 cm

Pythagoras theorem states that in a right triangle the sum of square of base and perpendicular is equal to square of hypotenuse.

Using, Pythagoras Theorem on Δ EDC,

$(EC)^2=(ED)^2+(DC)^2$

ED = 3 cm , EC = 10.5, Substitute, we get,

$\Rightarrow (10.5)^2=(3)^2+(DC)^2$

Solve for DC, we get,

$\Rightarrow 110.25=9+(DC)^2$

$\Rightarrow 110.25-9=(DC)^2$

$\Rightarrow (DC)^2=101.25$

$\Rightarrow DC=\sqrt{101.25}$

$\Rightarrow DC=10.06$

Since, ABCD is a rectangle. Thus, DC = AB

Hence, AB = 10.06 cm

The radius of a circle is 1 yard. What is the circle's circumference?<br> r=1 yd

matrenka [14]

Answer:

6.3 yards

Step-by-step explanation:

mathematically, to get the circumference of the circle, we will have to use the formula for the circumference of a circle

we have this as;

C = 2 * pi * r

r is 1 yard

c = 2 * pi * 1 = 2pi yards = 6.3 yards

Simplify the following expression.

Sloan [31]

Answer: $3x^{2}+12x$

Step-by-step explanation:

1. To solve simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.

2. Keeping this property on mind, you can rewrite the expression as following and simplify:

$\frac{-12x^{3}}{-4x}-\frac{48x^{2}}{-4x}=3x^{2}+12x$
