okay so i assume you meant these two:
y=-382 and y=6x+3
Answer:
y=-382
x=-385/6
Step By Step:
y=−382;y=6x+3
Step: Solve y=−382 for y:
y=−382
Step: Substitute −382 for y in y=6x+3:
y=6x+3
−382=6x+3
−382+−6x=6x+3+−6x (Add -6x to both sides)
−6x−382=3
−6x−382+382=3+382 (Add 382 to both sides)
−6x=385
Divide both sides by -6.
x=-385/6
y=-382

Step-by-step explanation:
(8)
the common ratio r, of a geometric sequence is
r = = = ......
r = = = 8
(9)
The simplest way to evaluate the sum is to substitute k = 3, 4, 5, 6 into each term and sum them
(- 9 + 20) + (- 12 + 20) + (- 15 + 20) + (- 18 + 20)
= 11 + 8 + 5 + 2 = 26
Answer:
The proportion of the variability seen in math achievement that can be predicted by math attitude is 0.78, the same value as the correlation coefficient.
Step-by-step explanation:
The correlation coefficient r between this two variables is found to be 0.78.
This coefficient can be calculated as:
where SSY' is the sum of the squares deviation from the mean for the predicted value and SSY is the sum of the squares deviation from the mean for the criterion variable.
Then, the value of the coefficient r is giving the proportion of the variability seen in the criterion value Y that can be explained by the predictor variable X.
