b. Quantitative variable
C. constant variable
d. Qualitative variable​

Answer 1

Answer:

quantitive variable I think

Answer 2

Answer:

In the regression equation X = a + by, the X is called dependent variable.

Explanation:

The equation of the linear regression line is of the form Y=a+bX where Y is called the dependent variable or response.

X is called the independent variable or predictor or explanatory variable a is the y-intercept and b is the slope of the line.

The symbol X represents the independent variable. The symbol a represents the Y-intercept.When X is zero, the value that Y .

independent variables are variables in mathematical modeling, experimental sciences,statistical modeling. Dependent variables are so called because the experiment examines their values under the assumption or requirement that they depend on the values of other variables according to some law or rule (eg, a mathematical function). Independent variables are in turn not considered dependent on any other variable within the scope of the experiment in question. In this sense, some common independent variables are time, space, density, mass, fluid flow rate, and prior values. some observed value of interest (eg, human population size) to predict future values (the dependent variable).
