Answer:
0.9113
Step-by-step explanation:
Given :
Sample standard deviation of Stock X = 4.665
Sample standard deviation of Stock Y = 8.427
Sample Covariance = 35.826
The Correlation Coefficient, R is related to sample covariance and standard deviation using the formular :
R = Covariance(X, Y) / (SD(X) * (SD(Y))
R = 35.826 / (4.665 * 8.427)
R = 35.826 / 39.311955
R = 0.9113
Hence, correlation Coefficient, R = 0.9113 which depicts a strong positive relationship.
Answer:
he would have to work 43 hours
Step-by-step explanation:
So if we know that at job one he gets payed 860 dollars a week and in job two he gets payed 20 per hour all we need to do is divide 860 by 20 to find the number of hours in a week and it would be 43
The angles are in the ratio of 5:6:9.
Let the angles be represented by:
5x, 6x, and 9x.
The sum of the interior angles of a triangle is 180.
5x + 6x + 9x = 180
20x = 180
x = 9
The angles are 5*9 = 45,
6*9 = 54,
and
9*9 = 81.
3/4+z=5/6
Find the common denominator which is 12 for 3/4 and 5/6.
Multiply by 3 for 3/4.
Multiply by 2 for 5/6.
3(3)/4(3)=9/12
5(2)/6(2)=10/12
9/12+z=10/12
Move 9/12 to the other side. Sign changes from 9/12 to -9/12.
9/12-9/12+z=10/12-9/12
z=1/12
Answer: z= 1/12
The answer is 13/24 i dont know how you want it
