Answer:

Step-by-step explanation:

Y = 389.10 - 14.6 X.

Here when X increases Y decreases so correlation coefficient is negative .

correlation coefficient = - √ .657

= - .81

Need help with this will give brainiest and 5 stars along with points.

Answer:

<em> f ( x ) = - 2x^2 + 3x + 1</em>

Step-by-step explanation:

If f ( x ) extends to → − ∞, as x→ − ∞ , provided f(x) → − ∞, as x → +∞, we can rewrite this representation as such;

− ∞  < x < ∞, while y > − ∞

Now the simplest representation of this parabola is f ( x ) = - x^2, provided it is a down - facing parabola;

If we are considering a down - facing parabola, the degree of this trinomial we should create should be even, the LCM being negative. Knowing that we can consider this equation;

<em>Solution; f ( x ) = - 2x^2 + 3x + 1</em>, where the degree is 2, the LCM ⇒ - 2

How do i solve for x 30x - 60 = 20x
Lena [83]
First, subtract 30x from each side to get:
-60 = -10x
Then, divide each side by -10 to get:
x = 6
Now, plug back in to check your answer:
30(6) - 60 = 20(6)
180 - 60 = 120
120 = 120

Hope this helps!! :)
