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
Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.
the answer is 81.9% hope this question will be helpful

Answer:
12.167
Step-by-step explanation:
The volume of any solid shape is the quantity or capacity it can contain. For example, if you have a closed tin of milf that is filled to the brim, the volume of the tin is the quantity of milk that is in the tin.
Given any cube with side length s, the Volume V=
If the cube has a side length of 2.3 centimeters
Volume== s X s X s = 2.3 X 2.3 X 2.3=12.167
Volume of the Cube = 12.167
