Angle E = the arc tangent (4 / 8)
Angle E = 26.565 Degrees
Yes, a quadratic model does exist and its equation is f(x)=4x^2
Answer:
3*(7 + 2) = 3*7 + 3*2
Option 3
Step-by-step explanation:
Distributive property of multiplication over addition:
a*(b+ c) = (a*b ) + (a * c)
A line parallel to the given one will have the same slope, 0.5. For the purpose here, it is convenient to start with a point-slope form of the equation, then simplify. For slope m and point (h, k), the equation of the line can be written as
... y = m(x -h) +k
We have m=0.5, (h, k) = (-9, 12), so the equation is ...
... y = 0.5(x +9) +12
... y = 0.5x +16.5
The variables have a negative association/correlation, because when one value increases (ex: x) the other decreases (see y)
If you would put a line through the dataset most of the points would be quite a bit off the line so the association is only moderate and not strong
so the answer is it is a "moderate negative association"
