Answer: b. 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.

1.6x=1.28<br> help me solve this
bogdanovich [222]

Answer:

Step-by-step explanation:

Sure! So, we need to divide by 1.6 on each side to isolate the x.

1.6x / 1.6 is just x. We need to divide by the same on the other side too!

1.28 / 1.6 is 0.8.

So x = 0.8
