Answer: none of the above
Explanation: it’s d.
Answer:
A(7,4)
Step-by-step explanation:
-2/3 is the slope and the slope is the rise over the run, and we know it passes through the point (1,8).
Next, we can create a chart/table
X int-1+3=4, 4+3=7
Y int-8-2=6,6-2=4
1st point: (4,6)
2nd point: (7,4)
Hope I helped, have a nice day :)
Answer:
x^10
Step-by-step explanation:
Answer:
-1/7
Step-by-step explanation:
If you count up once, for the y-value, then count over 7 times for the x-value, you get 1/7, rise over run.
Then, if you see the slope going backwards, you can see it is negative. Therefor, we get -1/7 for the slope.
Answer:
Step-by-step explanation:
Hello!
You have two regression models:
The multiple regression model that was estimated is y=40.7+ 8.63x1+ 2.71x2
The Simple regression model that was estimated is y=42.0+9.01x1
a.
MRmodel the 8.63 represents the modification in the estimated mean of Y when X₁ increases one unit and X₂ remains constant.
SRmodel the 9.01 represents the modification in the estimated average of Y when X₁ increases one unit.
b.
Yes, since both variables X₁ and X₂ are correlated, the effect that X₁ has over Y is directly affected by the precence of X₂
I hope you have a nice day!
