B=3a+2. It can be checked by plugging in the numbers. 1) 8=3(2)+2. 8=8. 2) 14=3(4)+2. 14=14. 3) 20=3(6)+2. 20=20.
Answer:
A
Step-by-step explanation:
Simple linear regression is a statistical method that summarizes and study relationships between two continuous quantitative variables.
One variable is regarded as the predictor, explanatory, or independent variable and the other variable is regarded as the response, outcome, or dependent variable.
Two variables can be denoted by X and Y.
Among the given options, the correct option is A. After conducting a hypothesis test to test that the slope of the regression equation is nonzero, you can conclude that your predictor variable, X, causes Y
Distribute
a(b+c)=ab+ac or
a(b-c)=ab-ac
so
3(q-5)=3q-15
2(q+5)=2q+10
3q-15=2q+10
minus 2q from both sides
q-15=10
add 15 to both sides
q=25
Answer:
Z=20 Degrees
Step-by-step explanation:
We know that all of the angles of a triangle add up to 180, so:
65+55+ Angle A = 180
Simplify:
120+ Angle A = 180
Subtract 120 from both sides:
Angle A = 60
If you look at the bottom you can see that the 15 turns into 5, meaning it is being divided by 3, so:
60/3=20
Z=20 Degrees
