To write this expression as a positive exponent we use this rule of exponents: x^color(red)(a) = 1/x^color(red)(-a) 5^-3 = 1/5^(- -3) .
Correlation coefficient helps us to know how strong is the relation between two variables. The strength of the model is a strong positive correlation.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
Hence, the strength of the model is a strong positive correlation.

Answer:
![1002](https://tex.z-dn.net/?f=1002)
Step-by-step explanation:
First find difference between the divisors and remainders.
![16-10=6\\18-12=6\\21-15=6](https://tex.z-dn.net/?f=16-10%3D6%5C%5C18-12%3D6%5C%5C21-15%3D6)
Here, the difference between the divisors and remainders is equal.
So, the required number is equal to LCM of ![(16,18,21)-6](https://tex.z-dn.net/?f=%2816%2C18%2C21%29-6)
![16=2^4\\18=2(3^2)\\21=3(7)](https://tex.z-dn.net/?f=16%3D2%5E4%5C%5C18%3D2%283%5E2%29%5C%5C21%3D3%287%29)
LCM of ![(16,18,21)=2^4(3^2)(7)=1008](https://tex.z-dn.net/?f=%2816%2C18%2C21%29%3D2%5E4%283%5E2%29%287%29%3D1008)
Required Number ![=1008-6=1002](https://tex.z-dn.net/?f=%3D1008-6%3D1002)
Answer:
width= x-7
Step-by-step explanation:
l= 8x
Area = l*b
b= 8x^2-56x/8x
b= 8x(x-7)/8x
b= x-7
Answer:
d
