R + b = 49
b = 6r
r + 6r = 49
7r = 49
r = 49/7
r = 7 <== he has 7 red beads
b = 6(7)
b = 42 <== he has 42 blue beads
Answer:
The Triangle
Step-by-step explanation:
<span>A correlation
coefficient is a measure of the strength of dependence and correlation of a set
of data. It shows how good is the fitted model to the data. It will have values
ranging from -1.0 - 1.0. Having a coefficient that is the lower or the upper
limit will tell you that the model best fit the data and a good correlation.
However, as it goes farther from the limits then the correlation is to be a bad
one.</span>
Minus 6 both sides
4>x/3
times3 both sides
12>x
The vertex of the parabola
has the coordinates:
Therfore, the vertex of the parabola
has coordinates
and
![y_v=(-3)^2+6\cdot (-3)+2=9-18+2=-7.](https://tex.z-dn.net/?f=y_v%3D%28-3%29%5E2%2B6%5Ccdot%20%28-3%29%2B2%3D9-18%2B2%3D-7.)
Answer: (-3,-7)
