Answer:
x = 6, y = -4
Step-by-step explanation:
x=-2y-2
4x+2y=16 .... divide by 2 both sides
2x + y = 8 ... subtitute x
2 ( -2y - 2) + y = 8
-4y - 4 + y = 8
- 3y = 8 + 4 = 12
y = -4
x = (-2 * -4) - 2 = 6
X=21

Answer:
0.9662 ;
There is a strong positive relationship between the stocks.
Step-by-step explanation:
Given :
Standard deviation of stock X = 4.668
Standard deviation of stock Y = 8.006
Covariance of sample = 36.109
The Correlation Coefficient, r :
(Covariance of Sample (X, Y)) ÷ (standard deviation of X * Standard deviation of Y)
r = 36.109 / (4.668 * 8.006)
r = 36.109 / 37.372008
r = 0.9662
Given the value of the correlation Coefficient, we can infer that there is a strong positive relationship between the two stocks, (X, Y). That is Stock X increases as stock Y increases and vice versa.
