Answer:
Step-by-step explanation: what is the last word
Answer:
There is a significant relation between weight and price
Step-by-step explanation:
Brand Weight(x) Price ($)
(y)
A 17.8 2100
B 16.1 6,250
C 14.9 8,370
D 15.9 6,200
E 17.2 4,000
F 13.1 8,500
G 16.2 6,000
H 17.1 2,580
I 17.6 3,500
J 14.1 8,000
Null Hypothesis :
Alternate Hypothesis :
Given : SST=51956800 SSE= 7312286.84 n = 10
SSR = SST-SSE
SSR=51956800-7312286.84
SSR=44644513.16
Level of significance =
Where m = no. of restrictions
k = No. of independent variables
F=48.843
Degree of freedom 1 = 1
Degree of freedom 2 = 10-2=8
Using calculator
p-value is .000114.
p value < α
So, we reject the null hypothesis .
Hence There is a significant relation between weight and price
First we will obtain the original coordinates
A = (-3, 4)
B = (-1, 4)
C = (1, 1)
D = (-5,1)
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).
The reflection of the point (x,y) across
the line y = -x is the point (-y, -x).
A' = (-4, 3)
B' = (-4, 1)
C' = (-1, -1)
D' = (-1, 5)
