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.

5/3 is already in its simplest form. It can't be equally divided. It can only be turned into a proper fraction. (1 2/3)
Answer:
t = 10.2
Step-by-step explanation:
We have the following exponential equation.

We divide both sides by 500.

We apply logarithm to both sides.

We use the logarithm power rule.

Finally, we solve for t.
t = 10.2
