Which of the following selected variables, associated with clinical trials of a drug, are quantitative variables? check all that apply.(a) dosage form - 1=tablet, 2=capsule, 3=liquid solution, 4=other(b) age (in years) - < < 20, 20-30, 30-40, 40-50, 50-60, 60 or above(c) smoking history (cigarettes per year)(d) body mass index (kg/m2kg/m2)(e) gender - male, female

The correct options are:

C) Smoking history (cigarettes per year) is correct.

D) Body mass index (kg/m2kg/m2) is correct.

Step-by-step explanation:

Consider the provided information.

The value of quantitative Variables can be determined by counting or measuring something.

The value of qualitative Variables can't be determined by counting or measuring something.

Now consider the provided options:

Option A) Dosage form - 1=tablet, 2=capsule, 3=liquid solution, 4=other

This is not a quantitative Variables, because we can't determined the value by counting the measuring.

Option B) Age (in years) - <<20, 20-30, 30-40, 40-50, 50-60, 60 or above

This is not a quantitative Variables

Option C) Smoking history (cigarettes per year)

We can count the number of cigarettes per year so it is  a quantitative Variables.

Thus, the option C) Smoking history (cigarettes per year) is correct.

Option D) Body mass index (kg/m2kg/m2)

We can count the Body mass index as it is a numerical value.

Thus, the option D) Body mass index (kg/m2kg/m2) is correct.

Option E) Gender - Male, Female

This is not a quantitative Variables, because we can't determined the value by counting the measuring.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

is there more to this question?
