Answer:
y = 2x + 1
Step-by-step explanation:
The gradient of line A is
Parallel lines have the same gradient, so m = 2.
Substituting the coordinates of P into y = mx + c,
Simple count by 2's to tens
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:
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%.
Answer:
4 19/20
Step-by-step explanation:
9 1/4 + 5 4/5 = 15 1/20
20- 15 1/20 = 4 19/20
7.25+6+6+4.25+20=$43.5
