The median would be the average between the 2 numbers.
Ex :
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
The average between 6 and 7 would be 6.5, so the median would be 6.5.
Answer:
B
Step-by-step explanation:
X = The amount of cd's
Y = Jewelry sets
X + Y = 50
X + 8y<_50
20 + 8Y<_50
Subtract 20 from both sides.
8Y<_30
Divide by 8 on both sides
Y<_3.75 (3 total)
She can buy 3 jewelry sets.
Infinity depends on the graph you are looking at but should be positive
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.
