X* y = -7
x + y = 12

what are the values of x and y?

The question that you should ask yourself is “what are the factors of -7 that adds up to 12?” And you will find out that 7 is prime so the only factors that could ever be are 7 and 1, however, they don’t add up to 12 so the answer is prime.

Ordinal Scale

Step-by-step explanation:

An ordinal scale is a system (of measurement) that classifies cases (measures) into ordered groups using tags or labels rather.

One must remember that an ordinal scale means that classes must be ordered in such a way that each case in one class is considered to be greater than (or less) every case in another class.
