The answer is "Nominal".

Explanation:

It represents a category parameter that has no natural order or categorization. These probabilistic methods can be represented by integers if you like, but the ordering is arbitrary, and computations, like computing an average, mean, or baseline, have no value.

This nominal scale is a measurement scale used to categorize occurrences or things into distinct classes. Its usage of numeric value or class divisions will not need this form or scale; just distinct IDs are needed to label every single group.

x = 7

step-by-step explanation:

equating the expression for area to the given area

2x² - 7x - 4 = 45 ( subtract 45 from both sides )

2x² - 7x - 49 = 0 ← in standard form

to factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 49 = - 98 and sum = - 7

the factors are - 14 and + 7

use these factors to split the middle term

2x² - 14x + 7x - 49 = 0 ( factor the first/second and third/fourth terms )

2x(x - 7) + 7(x - 7) = 0 ← factor out (x - 7)

(x - 7)(2x + 7) = 0

equate each factor to zero and solve for x

x - 7 = 0 ⇒ x = 7

2x + 7 = 0 ⇒ 2x = - 7 ⇒ x = -

thus the positive value for x is x = 7

the correct answer is "hematoma formation, with ligaments that are stretched, partially, of fully torn" ankle sprain are produced by an injury to the tough bands of tissue (ligaments) that surround and connect the bones of the leg to the foot. this causes several damage to the ankle including hematoma formation and ligament injury .
