Answer:
Option C and D that is y= tan x and y= cot x
Step-by-step explanation:
The range is the values of y means the values that y can take in a function:
So, range of tan x and cot x are all real numbers.
Period of tan x is 
Period of cot x is 
Option A and B that is secx and csc x are discarded
the domain of a function is the domain of its inverse -- This is False.
Answer:
56 ft
Step-by-step explanation:
Perimeter is the distance around the shape
18 x 2 + 10 x 2 =
36 + 20 =
56 ft
She hit 35% of the times.
35% of 20
= (35/100) * 20
= 0.35 * 20
= 7
Answer:
C. heteroscedasticity
Step-by-step explanation:
The OLS regression assumption of error variance being constant irrespective of independent variables, is called Homoscedasticity.
Var (u | x) = σ^2 (u) ;
where u = error term, x = independent variable, σ^2 (u) = constant error variance
The violance of this assumption ie Var (u | x) is related to independent variable x, is called Heteroscedasticity.
