Answer:
A. 1/2 of a goal
Step-by-step explanation:
Hello!
Given the options:
A. 1/2 of a goal
B. 3/4of a goal
C. 1 goal
D. 4/3 goals
In a linear regression analysis the interpretation of the slope is:
> The modification of the average of Y when X increases one unit.
Given the variables
Y: Goals scored in the tournament.
X: Hours of training.
To calculate the slope, you have to use the y-intercept and choose two pairs of (Y;X) values that correspond to a value on the line, for example (1;1.5) and (2;1.5).
You can calculate the slope as b= ΔY/ΔX

1st value (X₁;Y₁)= (0;1)
2nd value (X₂Y₂)= (1;1.5)
So the average goals a player scores for every additional hour of practice is 1/2.
I hope this helps!
No, because it is not a solution to the linear system shown above
Answer:
D. 0
Step-by-step explanation:
Well we know that A+B+C=180
and we know that A=45 and B=90
so together there 135
180-135=45
so C=45
now we also know that a straight line is 180 degrees so 180-45 =135(angle f)
135+15(angle e)=150
180-150=30
so angle d=30
