What is the distance between (–4, –10) and (–4, –4)?

Gre4nikov [31]

Answer:

6 units

Step-by-step explanation:

(-4 , -10) ; (-4 , -4)

Distance = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$= \sqrt{(-4-[-4])^{2}+(-4-[-10])^{2}}\\\\= \sqrt{(-4+4)^{2}+(-4+10)^{2}}\\\\=\sqrt{0+(6)^{2}}\\\\= \sqrt{36}\\\\= 6$

You have fit a regression model with two regressors to a data set that has 20 observations. The total sum of squares is 1000 and

Llana [10]

Answer:

Hence the adjusted R-squared value for this model is 0.7205.

Step-by-step explanation:

Given n= sample size=20

Total Sum of square (SST) =1000

Model sum of square(SSR) =750

Residual Sum of Square (SSE)=250

The value of R ^2 for this model is,

R^2 = \frac{SSR}{SST}

R^2 = 750/1000 =0.75

Adjusted $R^2$ :

$Adjusted R^2 =1- \frac{(1-R^2)\times(n-1)}{(n-k-1)}$

Where k= number of regressors in the model.

$Adjusted R^2 =1-(19\times 0.25/((20-2-1)) = 0.7205$
