When constructing an inscribed square, how many lines will be drawn in the circle?

The correlation coefficient between two quantitative variables is approximately 0.6. What does the value of this correlation coe

Answer:

The model does not fits the data well.

Step-by-step explanation:

Correlation:

Correlation is a technique that help us to find or define a relationship between two variables.

It is a measure of linear relationship between two quantities.

A positive correlation means that an increase in one quantity leads to an increase in another quantity
A negative correlation means with increase in one quantity the other quantity decreases.

R-square, $R^2$

The quantity R-squared is an indicator of the predictive power of a model.
It explains the variation in the dependent variable due to independent variable.
It shows how well the model fits the data.
R-squared is also known as the coefficient of determination.

$R^2 = \text{(Correlation coefficient)}^2= (0.6)^2 = 0.36 = 36\%$

Therefore, only 36% of the variations in the dependent variable is explained by the independent variable in the model which means more than 50% of variation cannot still be explained in the dependent variable.

Hence, the model does not fits the data well.

The polygons are similar. Find the value of x and y.

harina [27]

Answer:

x = 9, y = 27

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

$\frac{x-1}{6}$ = $\frac{16}{12}$ ( cross- multiply )
