Answer:
100
Step-by-step explanation:
Put the values where the corresponding variables are, then do the arithmetic.
(-4 -2)^2 +(3 -(-5))^2
= (-6)^2 +(8)^2
= 36 +64 = 100
Answer:
No
Step-by-step explanation:
The ratio of 2 : 5 would be 2/5 or .4
The ratio of 5 : 2 would be 5/2 or 2.5
These are not equal.
Step-by-step explanation:
We need to find the value of x for all problems if Y is between X and Z.
For all cases, XZ = XY+YZ
4. XY = 5x, YZ=x, and XZ=25
Putting all values
25 = 5x + x
25 = 6x
5. XY = 12, YZ=2x, and XZ = 28
28 = 12 + 2x
x = 8
6. XY = 4x. YZ=3x, and XZ = 42
XZ = XY+YZ
42 = 4x + 3x
42 = 7x
x = 6
7. XY=2x + 1. YZ = 6x, and XZ=81
XZ = XY+YZ
81 = 2x + 1 + 6x
80 = 8x
x = 10
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.
