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!
Answer:
29.24 grams
Step-by-step explanation:
It is given that,
Rachel's chocolate bar is 43% cocoa
The weight of the chocolate bar is 68 grams
We need to find how many grams of cocoa does it contain. It means it will contain 43% of 68 grams. It can be solved as follows :

Hence, it will have 29.24 grams of cocoa.
The answer will be (x-9) with a little two in the corner *2
Answer:
Volume = 1539.38 cm³
Surface Area = 747.7 cm²
Step-by-step explanation:
Volume = πr² h
V = π(7)²(10)
V = π(49)(10)
V = 490π
V = 1539.38 cm³
Surface Area = 2πrh + 2πr²
SA = 2π(7)(10) + 2π(7)²
SA = 2π(70) + 2π(49)
SA = 140π + 98π
SA = 238π
SA = 747.7 cm²
Answer:
42.25cm^2
Step-by-step explanation:
8+5+8+5 = 26
26/4 = 6.5
6.5x6.5 = 42.25
