Answer:
Ŷ = 76.4064+5.4254X
0.786
Strong positive relationship
Score = 98
Step-by-step explanation:
Using technology, the linear model obtained by fitting the data is :
Ŷ = 76.4064+5.4254X
Where, slope = 5.4254
y = test score ; x = study time
The Correlation Coefficient obtained is 0.786 ; which depicts that there exist a strong positive relationship between the two variables.
Using the model; test score, if x = 4
Ŷ = 76.4064+5.4254(4)
Y = 98.108
Test score = 98
Answer: v=-1/20
Step-by-step explanation:
-1/8v=5/2
-1 x 2=8v x 5
-2=40v
40v=-2
40v/40=-2/40
v=-1/20
