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%
False, it can. I hope this helps
To figure out one measure of a triangle, we use A2+B2=C2
(Where a is the first measure times itself, b is the second side times itself and c is the longest side times itself). Once you figure that out and plug all your numbers into the formula, you can solve like a regular equation. 45 times 45 is 2,025. 85 times 85 is 7,225. We don't know c so we just put that as C2. Our equation- 2,025+7,225= C2
Add the numbers to get 9,250= C2
Our answer is 96. (Because 96 times itself is 9,250). The answer is not exact so I just rounded it to the nearest whole number.
X² - 6x + 7 = 0
x² - 6x = -7
x² - 6x + 9 = -7 + 9
(x-3)² = 2
