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:
12x-3y
Step-by-step explanation:
10x3 + x + X
Group like terms
10x + x +X-3
Add similar elements: 10x + x + x = 12x
= 12x - 3y
Answer: Probability that the proportion of students who graduated is greater than 0.743 is P = 0.4755
Step-by-step explanation:
Given that,
Probability of freshmen entering public high schools in 2006 graduated with their class in 2010, p = 0.74
Random sample of freshman, n = 81
Utilizing central limit theorem,
So,
= P( Z > 0.0616)
= 0.4755 ⇒ probability that the proportion of students who graduated is greater than 0.743.
