Answer:
Step-by-step explanation:
Given the regression equation :
y=2+3x
Mean of y values ; y = 5.0
Where y is the predicted variable ; x = predictor variable
The predicted value of y for X = 2
Null: H0 = 5
Alternative H1 : ≠ 5
Sample size (n) = 10 pairs
Degree of freedom = n - 2 = 10 - 2 = 8
Answer:
just simplify it ...
Step-by-step explanation:
- 4a-b+4b-a=180
- 3a+3b=180
- 3(a+b)=180
- both sides divide by 3
- a+b =60
- b=60-a
The formula is for slope is y2-y1/x2-x1 so 3- -1 = 4 and -2 - 4 = -6 so it would be 4/-6
Answer:
1. x ≤ 400
2. x ≥ 200
3. x < 20
Step-by-step explanation:
I am pretty sure that this is right. :)
Answer:
D.
Step-by-step explanation:
Graph the line using the slope and y-intercept, or two points.
Slope: −4
