Answer: 31%
Step-by-step explanation:
Formula : Percent of the variability = 
, where 
= Coefficient of Determination.
SSR = sum of squares of regression
SST = total sum of squares
is the proportion of the variation of Y that can be attributed to the variation of x.
As per given , we have
SSR = 14.55
SST= 46.8
Then, the percent of the variability in y that can be explained by variability in the regression model =
Hence, the percent of the variability in y that can be explained by variability in the regression model = 31%
Answer:
3602.
Step-by-step explanation:
The formula is:
Population after n years = 2000( 1.04)^n
After 15 years the population will be 2000(1.04)^15
= 3602.
The answer is infinite solution.
3(4x)+3(-1) = 12x-3
12x-3 = 12x-3
Answer:
One leg: 3
So, the hypo: 2*3 = 6
And the third is according to the formula for right angle triangles: a^2 + b^ = c^2
So: √9+36= c
6.7 to get an exact number round it: 7
