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.

Answer:
y=.75x
Step-by-step explanation:
We use percents in decimal form to multiply it with the price. We convert percents into decimals by dividing the percent number by 100. For example, 78% divided by 100 becomes 0.78.
For finding the price we pay during a sale, we focus on the percent we pay. If 25% off is the sale, then we spend 75% or 100-25=75. 75% is 0.75. Multiply that by x an unknown price and we have 0.75x.
y=.75x
Answer:
10.34% probability that you both pick chocolate
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, it is not important if you or your friends picks first. So we use the combinations formula to find the number of desired and total outcomes.
Combinations Formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.

Desired outcomes:
10 are filled with chocolate, and we want to pick 2. So

Total outcomes:
The box has 30 chocolates, and 2 are picked, so:

Probability:

10.34% probability that you both pick chocolate
2(w + 2w+6) = 9090
6w + 12 = 9090
6w = 9078
w = 1513m
l = 2w+6 = 3032m
