Answer:
Option C is correct.
The value of r=0.2 represents the weakest correlation.
Step-by-step explanation:
Strongest correlation states that a linear relationship is indicated by a correlation coefficient of -1 or 1.
Weakest correlation states that a linear relationship is indicated by a correlation coefficient equal to 0 or if the value is nearest to 0, then it also represents the weakest correlation.
From the options, the only r-value that is very close to 0 is 0.2.
Therefore, the r-value represents the weakest correlation is, 0.2
22.50-3.75= 18.75
18.75/1.25= 15
1.25 × X = total money left after purchases.
Answer:
31 x 8,203 = 254,293
Step-by-step explanation:
Answer:
A: -16/3
B: 16/3
C: -6
D: -6
E: 6
Step-by-step explanation:
A would be -16/3 because you multiply -2 time 8 which is 116. And the denominator is 3.
B would be 16/3. It is the same as problem A but there are two negatives which make positive.
C is -6. You just divide -18/3.
D is the exact same as C. It just has parenthesis but the answer is still -6.
E is 6 because there are two negatives which make a positive.
Answer: 7 π r² + π r³
Explanation:
1) The general formula for the volumen, V, of a cylinder with radius r and height h is:
V = π r² h
2) Now you have the condition that the height is 7 inches greater than the radius, that is:
h = 7 + r
3) Replace h with its expression
V = π r² (7 + r)
4) Expand the product (use distributive property):
V = π (7r²) + π r³ = 7 π r² + π r³
Answer: 7 π r² + π r³
