Answer:
The variable that is being predicted is the <u>dependent variable</u>.
Step-by-step explanation:
The regression analysis is used to determine the effect on the response or dependent variable with every one unit change in the predictor or independent variable.
In case of simple linear regression there is only one independent variable and in cases of multiple linear regression there are more than one independent variables.
The general form of simple linear regression is:
The general form of multiple linear regression is:
The dependent variable are usually denoted by the letter "<em>y</em>" and the independent variables are usually denoted by the letter "<em>x</em>".
Thus, the variable that is being predicted is the <u>dependent variable</u>.
Answer:
Step-by-step explanation:
3pink,5red,4yellow. 12 total roses. Probability of selecting a pink rose would be 3/12 or 1/4. The complement of that would be 1-1/4=3/4. So theres a 3/4 chance that she WON'T randomly select a pink rose. Answer=3/4

Answer:
D. (-3, -2)
Step-by-step explanation:
The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.
Using (x, y) = (-2, -3):
x = y -1 ⇒ -2 = -3 -1 . . . . False
Using (x, y) = (-3, -2):
x = y -1 ⇒ -3 = -2 -1 . . . .True
2x = 3y ⇒ 2(-3) = 3(-2) . . . . True
The solution is (-3, -2).

If you'd like to solve the set of equations, substitution for x works nicely.
2(y -1) = 3y
2y -2 = 3y . . eliminate parentheses
-2 = y . . . . . . subtract 2y
x = -2 -1 = -3
The solution is (x, y) = (-3, -2).
