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!
The student would have 8 $5 bills and 7 $1 bills because 5*8=40 and 7*1=7 and adding them together makes 47! Hope that helps!
Answer:
number of green counters
=12-3+1+2
=6
number of green and yellow counters
=6+2
=8
probability of getting green or yellow counter
=8/12
=2/3

Answer:
This type of essay answer is pretty short.
You play out the equation and say what each part of the equation means. The vertex in this case, because it's a downward facing parabola, is the highest point on the graph. Now since they're kicking a ball, the vertex will be the highest point that the ball will go up to.
Hopefully this helps some. For full points you'll probably have to add a bit of padding and further explanation.
Step-by-step explanation:
1) use the distance formula to find that the radius (r) of the circle = 5
2) use the midpoint formula to find that the center of the circle (h,k) = (3, 0)
3) Now use the formula of a circle and input the (h,k) and r to create:
(x - 3)² + (y - 0)² = 5² → (x - 3)² + y² = 25
4) input the "x" value given in the question (x = 0) and solve for "y":
(0 - 3)² + y² = 25 → 9 + y² = 25 → y² = 16 → y = +/- 4
Since the question states that "b" must be positive, you can disregard the -4.
Answer: b = 4
