Use elimination method to get -8
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
Answer:
Step-by-step explanation:
h(x) = 36 - 4.9x^3
Let x be 1.3
The question is not entirely clear. Looks like the iphone moved. Not only that, but the question is not really clear either. I'm taking it to mean that h is the distance from the GROUND to the ROCK after 1.3 seconds.
h(x) = 36 - 4.9(1.3)^2
h(1.3) = 36 - 4.9 * 1.3 * 1.3
h(1.3) = 36 - 27.719
h(1.3) = 8.28 m
