Complete Question:
Attached below as picture.
Answer:
From first graph there is no linear pattern so here linearity assumption violated.
From second graph there is observation is in some pattern like funnel or v shape so there is no constant variance occur that is there is no constant variance for error.
Constant variance for error occur when in residual plot all observation are in scatter everywhere.
From third graph we can say there is positive distribution but for regression analysis we need symmetric that is normal distribution.
Step-by-step explanation:
See graphs attached below.
Answer:
The leverage of an observation is determined by how far the values of the independent variables are from their means.
4)
ordered pairs : (-5,4)(-3,2)(2,6)(-3,-5) it is not a function because it repeats x’s
5)
ordered pairs : (4,5)(2,5)(1,-3)(-2,-2) it is a function because it is NOT repeating x’s
6)
(2,6)(6,8)(6,10)(8,12) it is not a function because it repeats x’s
102 times 4 =408
i know this because a square has 4 sides and i just need to multiply 102 and 4
You would want to use the Keep, Change , Flip
method. So you keep the 1/8, change division into multiplication, the flip the 4 into 1/4.
Step-by-step explanation:
(1/8) / 4
(1/8) * (1/4)
answer: 1/32 or 0.03125
