Answer:
Factor analysis
Step-by-step explanation:
Factor Analysis is a method for modeling observed variables, and their covariance structure, in terms of a smaller number of underlying unobservable “factors.” These factors are typically viewed as broad concepts or ideas that may describe a noted occurrence.
Take for example:
A basic impulse of acquiring a certain social level might explain most consumption behavior. These unobserved factors are more interesting to the social scientist than the noted numerical measurements.
The employee discount is 30% off. Here's the process to find this answer:
Calculate the difference between the original price and the discounted price. We're trying to find the percentage of the discount, not the percentage 38.50 is of 55.
55 - 38.5 = 16.5
Multiply the difference by 100 as part of the percentage formula. (is over of is equal to the percentage over one hundred)
16.5 * 100 = 1,650
Divide your result by 55 as the final part of the percentage formula.
1,650 / 55 = 30
Answer:
Answer: FIRST OPTION
Step-by-step explanation:
The missing picture is attached.
By definition, given a Quadratic equation in the form:
Where "a", "b" and "c" are numerical coefficients and "x" is the unknown variable, you caN use the Quadratic Formula to solve it.
The Quadratic Formula is the following:
In this case, the exercise gives you this Quadratic equation:
You can identify that the numerical coefficients are:
Therefore, you can substitute values into the Quadratic formula shown above:
You can identify that the equation that shows the Quadratic formula used correctly to solve the Quadratic equation given in the exercise for "x", is the one shown in the First option.
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
