Anon25 [30]3 years ago
6 0

Answer:

3. x = y - 3

Step-by-step explanation:

You want to move all numbers on the same side of x to the other side with y. Whenever doing this, we have to reverse the operation. In this problem, we have + 3 with x. So we will need to subtract 3 from both sides.

x + 3 = y

x = y - 3

Step-by-step explanation:

We know that , the indicator variable is a dummy variable in regression analysis which is used to denote either presence ( by 1 ) or absence ( by 0 ) of a nominal variable that can be responsible for the change in output.

Number of indicator variables = (all levels in the original variable)-1

Here , the given categories as per the location are northeast, northwest, southeast, or southwest.

i.e. all levels in the original variable = 4

Then, the umber of indicator variables we need = 4-1 =3

Hence, we need 3 indicator variables.

Thus , the correct answer is b. 3.
