Categorical variables can assume values from a range of possible options, whereas quantitative variables can assume possibly infinitely many values from a certain number range.
So, the answer is "the colour of the bookshelf", because there can only be a limited number of possible colours for the bookshelf, whereas its width (no matter the unit measure) and height could be any number.
Answer:
B) part
Step-by-step explanation:
Cos 157.5º=-cos (180º-157.5º)=-cos 22.5=-cos(45/2)
cos Ф/2=⁺₋√((1+cosФ)/2).
In this case 157.5º is in the second quadrant, therefore we use the following equation:
cos Ф/2=-√((1+cosФ)/2). (we will have a negative number)
cos 157.5º=-cos (45/2)=-√((1+cos 45º)/2)
=-√((1+√2/2)/2)
=-√((2+√2)/4)
=-√(2+√2) / 2 (≈-0.92387...)
Answer: cos 157.5º= -√(2+√2) / 2
