Answer:

B. ​No, because while there is no linear​ correlation, there may be a relationship that is not linear.

Step-by-step explanation:

Relationships between variables are diverse and fitted model of a dataset for each of the models will usually differ. That is the lebl of association between variables for a linear model may differ and better than a quadratic model or an exponential may perform. For r = 0 ; this means no relationship exists between the variables, however , this is the information for the linear model, which clearly depicts that no assicitio exist for the linear fit. A model change could result in a differ and slightly or highly correlated R value.

Use the figure to answer the question.
Fiesta28 [93]

Answer:

1,530 cm³

Step-by-step explanation:

The figure consists of two rectangular prism or cuboid.

The dimension of cuboid 1:

l = 10cm, w = 9cm, h = 9cm

Volume_1 = l*w*h = 10*9*9 = 810 cm^3

The dimension of cuboid 2:

l = 18cm, w = 10cm, h = 4cm

Volume_2 = l*w*h = 18*10*4 = 720 cm^3

Volume of the figure = 810 + 720 = 1,530 cm³

Harrizon [31]

Answer:

<h2>(1, 4)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}2x=-y+6&(1)\\-4x+3y=8&(2)\end{array}\right\\\\(1)\\-y+6=2x\qquad\text{subtract 6 from both sides}\\-y=2x-6\qquad\text{change the signs}\\y=6-2x\\\\\text{substitute it to (2):}\\\\(2)\\-4x+3(6-2x)=8\qquad\text{use the distributive property}\\-4x+(3)(6)+(3)(-2x)=8\\-4x+18-6x=8\qquad\text{subtract 18 from both sides}\\-10x=-10\qquad\text{divide both sides by (-10)}\\x=1\\\\\text{put the value of x to (1):}\\\\y=6-2(1)\\y=6-2\\y=4
