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
:
Where k= number of regressors in the model.

I think it is D or it could be c?
Answer: 1. False. [∠XFG is lying between the one side and the line extended to the next side of the triangle, therefore it is an exterior angle.]
2.True. [∠EFG is lying between the two sides of the ΔEFG, therefore it is an interior angle of the triangle]
3.True. [∠FEZ is lying between the one side and the line extended to the other side of ΔEFG ]
4.False. [∠YGE is a straight line it is between the one side and the line extended to the same side ∴ it cannot be an exterior angle of the triangle ]
5. True.[∠EGF and FGY together make a straight line therefore they are supplementary angles]
6.False.[∠FEG and ∠FGE are both the interior angles of a triangle and we know that for supplementary angles they should lie on the same line or together make a straight line]
The area of a shape is the amount of space it can occupy.
<em>The value of r is 13</em>
From the question (see attachment), we have:
--- area of the shaded region
--- the width of the shaded region
The area of the complete circle would be:

The area of the small circle is:

So, the area of the shaded region is:

Substitute known values

Substitute 2 for w

Expand

Open brackets

Cancel out line terms

Divide through by 4

Factor out pi

Divide through by pi

Substitute 22/7 for pi

Using a calculator, we have

Solve for r


Hence, the value of r is 13
