Answer:
And for this case 
The % of variation is given by the determination coefficient given by
and on this case
, so then the % of variation explained is 20.25%.
The proportion of the variability seen in final grade performance that can be predicted by math ability scores is 20.25%.
Step-by-step explanation:
For this case we asume that we fit a linear model:

Where y represent the final grade and x the math ability scores
Where:
And we can find the intercept using this:
The correlation coeffcient is given by:

Answer:
D
Step-by-step explanation:
since we have a non decimal bigger than 0.1 we know exponent is positive, so we move count how many spaces we move from the last number and we get 9.01*10^5
54 degrees because the angles are equal
Answer:
2x3=6 and that the number of frogs heather has or you can do this Ava has 2 frogs and heather has 1/3 more then take the 2 and add it to the 1 and that makes three. then take both of the threes and add them together and you then have the same number of 6
