Answer:
y = 1
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 25 when x =
, then
25 =
= 5k ( divide both sides by 5 )
5 = k
y =
← equation of variation
When x = 5, then
y =
= 1
You already know that y equals -4. It says that x equals 3, so multiply the -4 by 3 and because it has a negative number and a positive number it will equal -12. Remember anytime you see a letter after a number it means multiply. The complete problem should be -10 because 2 is a whole number you subtract it from -12. Hope that helped you out some.

Answer:
y+2= -4(x-8)
Step-by-step explanation:
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.
