Answer:
The answer is
<h2>a = 11, b = 7</h2>
Step-by-step explanation:
![( {5x}^{7} {y}^{2} )( { - 4x}^{4} {y}^{5} ) = - 20 {x}^{a} {y}^{b}](https://tex.z-dn.net/?f=%28%20%7B5x%7D%5E%7B7%7D%20%20%7By%7D%5E%7B2%7D%20%29%28%20%7B%20-%204x%7D%5E%7B4%7D%20%20%7By%7D%5E%7B5%7D%20%29%20%3D%20%20-%2020%20%7Bx%7D%5E%7Ba%7D%20%20%7By%7D%5E%7Bb%7D%20)
Multiply the terms on the left side of the equation
That's
![- 20 {x}^{11} {y}^{7} = - 20 {x}^{a} {y}^{b}](https://tex.z-dn.net/?f=%20-%2020%20%7Bx%7D%5E%7B11%7D%20%20%7By%7D%5E%7B7%7D%20%20%3D%20%20-%2020%20%7Bx%7D%5E%7Ba%7D%20%20%7By%7D%5E%7Bb%7D%20)
Since the bases are the same we can equate the exponents
That's
![{x}^{11} = {x}^{a}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B11%7D%20%20%3D%20%20%7Bx%7D%5E%7Ba%7D%20)
a = 11
And
![{y}^{7} = {y}^{b}](https://tex.z-dn.net/?f=%20%7By%7D%5E%7B7%7D%20%20%3D%20%20%7By%7D%5E%7Bb%7D%20)
b = 11
Therefore
a = 11 and b = 7

R = 0.9
A value of 0.9 would indicate that the correlation is positive. Since it's also close to the value 1, it would also tell us that the correlation of y and x is strong. Therefore, r = 0.9 would be a strong linear association in which y increases as x increases.
r = -1.0
Since the value of r is negative, this would mean that the correlation is also negative. Furthermore, the value of r is also at the minimum point which is -1.0 thus this would tell us that the correlation is a perfect linear association in which y decreases as x increases.
r = -0.6
Likewise, this r value is also negative thus allowing us to know that y will decrease as x increases. The value of r, which is -0.6, is also close to -1.0. This allows us to tell that it is a strong relationship. Therefore, r = -0.6 is a strong linear association in which y decreases as x increases.
r = 0.1
For this correlation, the r value is positive. This would indicate that the value of y will increase as x increases. Since the r value is only 0.1, we cannot say that it is a strong relationship since it is far from the maximum value for a perfect relationship which is 1. Therefore, r = 0.1 is a moderate linear association in which y increases as x increases.
