Answer:
Distributive Property, Subtraction Property of Equality, Subtraction Property of Equality, Division Property of Equality
Step-by-step explanation:
First, you need to distribute. Next, you subtract on both sides. Then, you subtract again. Finally, you divide.

<span>2x+38=180 since all triangles add up to 180 and we have 38 as a degree we have to find the value of
2x=180-38
2x=142
x=142÷2
x=71</span>
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.
