2c+17.6 =6 / 4 SOLVE give your answer as a decimal get brainly
tamaranim1 [39]

Answer:

-8.05

Step-by-step explanation:

In order to solve for C you first have to subtract 17.6 from both sides.

2c=(6/4)-17.6

6/4 is 1.5

1.5-17.6=-16.1

2c=-16.1

c=-8.05

HACTEHA [7]

Answer:

R^2 = r^2 = 0.445^2= 0.198

B. The coefficient of determination is 0.1980, 19.8​% of the variation is explained by the linear​ correlation, and 80.2​% is explained by other factors.

Step-by-step explanation:

Previous concepts

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.  

Solution to the problem

In order to calculate the correlation coefficient we can use this formula:  

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}  

On this case we got that r =0.445

The determinaton coefficient is just:

R^2 = r^2 = 0.445^2= 0.198

And we can put it on % and we got 19.8%. And represent the variation explained by a linear model. The best option on this case would be:

B. The coefficient of determination is 0.1980, 19.8​% of the variation is explained by the linear​ correlation, and 80.2​% is explained by other factors.

Since the explained variation is 19.8% and the remain 100-19.8= 80.2% is explained by other factors.
