Well, lets take a look at our options here. Option C is incorrect because PR doesn't equal SQ. D is wrong because it just tells us the same thing, which doesn't help us. A and B are our only answers. B is wrong because we can already see that the angle is a right angle, but we don't know if the hypo is the same, which is needed because without it, we can't tell what the other 2 angles are. A is the right answer.

Step-by-step explanation: Qualitative variables simply refers to variables of non-numeric character, nature or property. They are usually employed in assigning variables into discreet groups. The nominal and ordinal scales are employed when dealing with qualititative or categorical variables, with nominal variables used when the classes or groups involved do not follow any definite order or rank. Example include classifying sex into (male or Female), and other categorical classification of discreet nature. The ordinal scale is usually employed when dealing with ranked classifications such as level of importance[very important, Important, not so important, unimportant] or grade[distinction, excellent, very good, good, fair, poor].
-y=-(x^2) because you multiply both sides by -1.
