You ll need to do it t times:
x1 y1 x2 y2
(-1, 5) (4, 2) = (-1, 5) (4, 2)
(4, 2) (0,0)
(0,0) (5,5)
(5,5) (-1, 5)
then add all your results
Answer:
c. 64% of the variation in the weight of luggage is explained by the number of passengers
Step-by-step explanation:
The explained variance is a measure given by the coefficient of determination, R².
The value Given above is the correlation Coefficient, R, which is 0.8
The Coefficient of determination, R² = 0.8² = 0.64, expressing as a percentage ; 0.64 * 100% = 64%
This means that 64% of the variation in the dependent variable is can be explained by the regression line. (independent variable)
Monomial to the 2nd degree
Well first add up all the numbers of marbles (which is 34 in total) and divide it by the number of black marbles.
(which should give you 8/34)
Then simplify the fraction and you should get 4/17
