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.
The statements that are true about this graph are the pumpkin grew at a rate of 6 ounces per week, and in 3 weeks the pumpkin grew to a total of 18 ounces.
<h3>What does 3,18 mean?</h3>

Answer:
No
Step-by-step explanation:
its not because x doesn't go into all 3 coffecients (numbers) and 6 doesn't go into 3.
22.6+x-1.2
22.6-1.2+x
21.4+x
