Answer:
The last one, Explanatory variable: player 40-yard-dash time
Response variable: player weight would be your answer. Hope this helps : )
Step-by-step explanation:
X + y = 10
x - y = 2
add the equations together
2x = 12
x = 6
6 + y = 10
y = 3

Step-by-step explanation:
Hello.
to find the volume of a sphere we must know its radius,
we don't know the radius but we have the area
Now, replacing this value in the volume equation
have a great day
The regression equation which correctly models the data in this table is y = 1.49x - 107.5,
<h3>How to determine the regression equation?</h3>
From the table of data values, we have the following parameters:
∑x = 632
∑y = 404
∑x² = 80.142
∑xy = 51.448
Mathematically, the regression equation is represented by the following slope equation:
y = Bx + A
Next, we would determine A by using this expression:
A = (∑y·∑x² - ∑x·∑xy)/(n∑x² - (∑x)²)
A = (404×80,142 - 632×51,448)/(5×∑x² - (632)²)
A = (32,377,368 - 32,515136)/(5×80142 - 399,424)
A = -137,768/1286
A = 107.5
For B, we have:
B = (n∑xy· - ∑x·∑y)/(n∑x² - (∑x)²)
B = (5×51,448 - 632×404)/(5×∑x² - (632)²)
B = 1.49.
y = Bx + A
y = 1.49x - 107.5
