Answer: in your case, point slope form will be y+1 = (the parellel slope or M)(x-0)

Step-by-step explanation:

basically the point slope form is suppose to be y - (y coodinate) = (M or slope)(x - (x coodinate) )

Parellel lines are the slope is the same, but the coordinates aren't

eg. what is the equation, in point slope form, of the coordinate of a line (3,4) that is parellel to the equation: y = 3/4x + 6

no. 1: slope is 3/4

no. 2 plug all info into the equation: y - (y coodinate) = (M or slope)(x - (x coodinate) )

no.3 you have your equation! y - 4 = 3 / 4 ( x - 3 )

You are considering developing a regression equation relating a dependent variable to two independent variables. One of the vari

lys-0071 [83]

Answer:

Step-by-step explanation:

a. How many dummy variables are needed to represent the categorical variable?

We need 1 less dummy variable than outcomes for the categorical variable.

categorical variable has 2 outcomes

So, we need 2-1 = 1 dummy variable.

Answer: 1

Note: If our categorical variable had 5 outcomes, we would need 5-1 = 4 dummy variables.

b. Write the multiple regression equation relating the dependent variable to the independent variables.

Note: Depending your your professor, this can be written one of the following ways...

yhat = a + b1 x1 + bx2

yhat = b0 + b1 x1 + b2 x2

yhat = beta0hat + beta1hat x1 + betahat2 x2

where x1 is the ratio variable

and x2 is the dummy variable

c. Interpret the meaning of the coefficients in the regression equation.

b0 = the predicted value of y when x1 and x2 both equal 0.

b1 = the change in y when x1 increases by 1 unit holding x2 constant.

b2 = the predicted difference in y between the two possible outcomes of the categorical variable holding x1 constant.

A fundamental basis of regression analysis is the assumption of a. the lack of a relationship between independent variables. b.

kodGreya [7K]

The correct answer is E. A fundamental basis of regression analysis is the assumption of the existence of two independent variables for every dependent variable.

Regression analysis is a statistical method that examines the dependence of a response variable on selected explanatory variables.

When studying the dependence between quantities and trying to describe a given functional dependence on a given formula, it is assumed that the dependence consists of a precisely determinable component and a random component. The relationship with this assumption is called the regression model.

If f(x)=x-1/3 and g(x)=3x+1, what is (f*g)(x) 3x+1 x-3

crimeas [40]

This is a composite. Another way to write them is f(g(x)). Take the function g(x) and stick it in for x in f(x). Like this: $f(g(x))= \frac{(3x+1)-1}{3}$ . But we aren't done cuz there's some simplifying there to do. $f(g(x))= \frac{3x}{3}$ and canceling out the 3's we get just a simple x as our answer. The choice is the last one above as your answer.
