morpeh [17]

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.

Levart [38]

Answer:

circumference=>2πr

circumference= 119.32 cm

π = 3.14

r =?

119.32 = 2 × 3.14 × r

r = 119.32/6.28

r = 19 cm

so area = πr²

area = 3.14 × (19)²

area = 3.14 × 361

area = 1,133.54 cm²
