Answer: this is wrong. The final answer should be x - 4y = 8

Step-by-step explanation:

y = 1/4x + 2

We'll first isolate the constant

-1/4x + y = 2

We remove the fraction by multiply through both sides of the equation

-4

x - 4y = 8

What is the volume of this rectangular prism?
Fynjy0 [20]

Answer: V≈5.21 cm³

Step-by-step explanation:

To find the volume of a rectangular prism, you multiply the length, width and height.

V=wlh

Since we were given the length, width and height, we can directly multiply them together.

V=\frac{5}{2} *\frac{5}{3} *\frac{5}{4}             [multiply]

V=\frac{125}{24} =5.21 cm^3

Now, we know that the volume is approximately 5.21 cm³ or 125/24 cm³.

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
